[spring finch]

Dont think so -- could it be the sprite atlas im using? I have no idea

[solemn latch]

It could absolutely be the sprite atlas. If the atlas is larger than the max size you have set, it will be downscaled

[spring finch]

I just have no idea why it would randomly happen upon reload

I think it was the sprite atlas!

[thick lake]

Just to confirm something - There is no way to assign a Grid component to a Tilemap/Tilemap Renderer/etc, right? The configuration requires a Parent game object with Grid, then for Tilemaps, Tilemap Renderer's, etc. to be on descendant game objects?

[spring finch]

I have a grid component with the child components as the layers...e.g background, collission - then I assign it to a tilemap

[unkempt ledge]

How can i remove these weird lines in unity? I am using a tilemap for my sprites

this is my settings for the sprite

[thick lake]

Let me rephrase - There is no way to have a Tilemap use a Grid from a separate, non parent game object?

[spring finch]

I am unsure

[fathom sky]

how do you make the Pixel perfect camera zoom out?

[frozen osprey]

Zooming out is antithetical to the purpose of pixel perfect camera

Or are you just asking how to set the target asset resolution

[runic tulip]

lmao you use the same tilesheet than me

[mortal acorn]

It's a great tilesheet lol

[finite harbor]

why cant i slice this spritesheet

[still tendon]

could you post a screenshot of what the Inspector displays when your sprite selected in Project view? The importer settings need to be Texture Type: Sprite and Sprite Mode: Multiple. That makes it possible to see the sprite slicing options in the Sprite editor.

[finite harbor]

ok i managed to figure it out

had to select multiple sprites then attach the secondary animation directly to my player object

[thick lake]

Hello all! I am creating Tilemaps in the editor and then saving them in separate scenes, which are additively loaded at runtime.

The sprites are displayed correctly in Play mode, but any game objects I have assigned to my tiles are not instantiated (even though they are correctly instantiated in the editor). As far as I can tell GetTileData is not being called when the scenes with the Tilemaps are loaded in.

Do we need to manually call Tilemap.Update or some other method to get the game objects intantiated?

I discovered the issue and I think this is a bug.

If you instantiate the prefab that has the Tilemap in an activated state, everything works as it should. If you instantiate the prefab in a deactivated state (by parenting it to a deactivated game object), it breaks. If you load a scene where the root game object (containing the Grid and child objects with Tilemaps) is deactivated, it also breaks.

So it appears that if the Tilemap is loaded in a deactivated state, it breaks the Tilemap. I am using Unity 2020.3.37f1, so it's possible this has been fixed in a later version.

Edit: I'll also add that it's not the case that the game objects are simply hidden. The game objects I have associated with my tiles are colliders that serve as the floor, so I can confirm whether they are being instantiated or not because the player falls through the floor when they are not.

[modest cargo]

What specifically was it that breaks?

[thick lake]

The game objects that are assigned to tiles are not instantiated.

[thick lake]

Just to add to this, calling Tilemap.RefreshAllTiles fixes the issue (I am calling it after activating the game objects with the tile maps). Interestly, however, BaseTile.RefreshTile is not called when RefreshAllTiles is called, although that doesn't seem to hurt anything.

[thick lake]

Back with another question . . . does anyone know why in Play Mode the bounds of the generated tilemap sprite (at least, that's what I assume the white rectangle with the blue circles in the corners represents) is so much larger than the actual tilemap area (area with tiles)? I tried adjusting the Chunk Culling Bounds and that has no effect on this.

[quaint crest]

i think i should ask this here not really sure, how can i change where that circle centerpoint is

im trying to just move the circle down a bit but i cant seem to do that

and when i put a parent empty game object it takes teh same exact shape/centerpoint

[errant surge]

Theres sometimes gray lines between my tiles.
The old brackeys tutorial i'm going off said to disable antiailiasing in quality settings, but it seems like that menu changed since then and i cant find antialiasing in it any more

apparently its also already disabled on the camera i'm using... any ideas

the video showed this, and you can see the gray lines in the screenshot

idk if everyone elses quality settings looks like this but its completely different for me

Anyway... if u know how to stop antialiasing or how i can use pixel perfect camera pls do tell

[sly solstice]

hey is there any reccomened ai tool for generating sprites?

[modest cargo]

MSAA is still in the quality settings if you're in built-in render pipeline, URP asset if you're using URP
Camera has the SMAA option (subpixel morphological) which is a different type of AA from MSAA (multi-sample) that should not cause seam issues
However seam issues can occur even without AA, such as when camera size does not precisely match the sprite PPU
Pixel perfect camera component is used to precisely set the camera size to eliminate that issue, but it requires you to conform to a pixel perfect workflow
Another workaround could be to decrease the PPU a very tiny bit so the sprite of the tile overflows its grid square by half a pixel or so

There may also be seams that show some of the tile's color, rather than background in which case it's a separate issue from color bleeding between tiles

[bleak pier]

how do you get a smooth camera movement with pixel perfect camera and pixel snapping turned on?

[modest cargo]

Fundamentally you cannot
It will always be jittery because one pixel is the smallest step the camera can take

[bleak pier]

i see, is there any good way to get around it? or at least make it a bit less jittery

[modest cargo]

The worst varieties of visual jitters occur when the camera and individual sprites are moving at similar speeds so that they're rapidly jumping between screen pixels as a result

That's the biggest problem you can eliminate, and it's usually caused by scripts that make the camera follow some gameobject

[bleak pier]

yeah i noticed that when the camera follow was off it was decently smooth, but i kinda need it to follow haha

[modest cargo]

If it has smoothing, the smooth deacceleration in particular is very likely to clash with the movement of sprites, especially the sprite it follows

Even with unsmoothed follow camera jitter may occur if the camera position is upated at a different frame than its follow target's, so that it would always trail one frame behind

If you want a follow camera, parenting is your best option since it's the most solid way to sync their positions
If you're using Cinemachine the process is trickier, but using LateUpdate may help

If you need a smoothed camera, it's best to have it follow very rarely, and if at all possible only in a straight line at a brisk pace from one position to the next
You can see an example of this in Celeste

A lot of the "clash" of the motion that causes jitter is because all gameobjects have floating point precision positions and are only later snapped to nearest pixels, this means the closest pixel to snap to can very rapidly change when your camera and every sprite can smoothly move sub-pixel distances per frame relative to each other

But even in old games where positions were all in pixels and movement was likewise measured in pixels, jitter did occur back then too since nothing fundamentally locks the "pace" at which they move together

Pixel jitter is kind of an optical illusion that we observe when two sprites or the sprites and a camera are changing their pixel position in the same direction too close in time to each other but not at the same time

Smooth follow camera just tends to create a huge number of opportunities for that to occur

[bleak pier]

i see! thank you so much, this was a huge help :D

[frozen osprey]

If your camera is snapped exactly to your player, I should add that you may want to design your game so that typical player speeds are something rounded-ish like 1, 1.5, or 2 pixels per frame

that can make a big difference for a smoother feeling result

Basically the shorter the "pattern" is, the smoother it will look.
Moving 1 pixels per frame is a repeating pattern of [ 1 ] every frame (great)
Moving 1.2 PPF is a repeating pattern of [ 1, 1, 1, 1, 2 ] (not so great, noticable jitter)
Moving 1.5 PPF is a repeating pattern of [ 1, 2 ] every frame (okay)

Though really if you can get away with it, it's probably better not to use pixel snapping unless you're a huge stickler for retro styling

[lilac grotto]

Hello can someone really help me this is such big issue

first time using maptiles and stuff so i try to create map tiles then after that i put in my brush i create more maptiles because some of them are just for background and others are for colliding but literally when working with it they overlap with each other when i save or start the game

and that is so frustating cant even do anything

im creating more layers but it doesnt work

nvm im a idiot you dont create the layers in hierachy is on the actual renderer thing

[plucky stag]

i am working on a 2d game where the player is a square and I want to display a different sprite on each side (to represent the different ability's) the player can change these in the inventory so I have to be able to swap them out individually, I was thinking about a modular sprite but I have no idea how to do that.

[solemn latch]

You can just have the secondary sprites be children of the character?

[carmine lantern]

hey everyone, does anybody know where I can find more detailed information on how Unity's sprite system works behind the scenes? I'm a student and want to write a paper on it, but all the information I can find is about how to use it, not what it actually does. For example, how does Unity process the sprite atlas assets? Does is read them with UVs? It would be a great help if you could direct me to a place where I can find out more...

[abstract olive]

What level of detail did you want? They're essentially just quads. If you're hoping for true behind the scenes code, you won't find anything on that without paying for source code.

[jaunty sequoia]

how can add a light 2d into a particle system

[carmine lantern]

Right now, I am having trouble finding anything at all, so any level of detail would be helpful. I am not a programmer tho, and only know some basic coding.

[elfin temple]

which app should i use for 2d sprites?

[finite dock]

for pixel i suppose aesprite

mostly seen people use krita

[elfin temple]

okk ty

[elfin temple]

is there a free version?

[finite dock]

na

[modest cargo]

LibreSprite is a FOSS branch of Aseprite which is some features behind in updates
Aseprite is also free to compile from source, in case you have the know-how

The premium version is well worth it though in my opinion

[solemn latch]

Sprites are stored as SpriteRects.

Which has the GUID, name, pivot, border, and rect.

https://docs.unity3d.com/ScriptReference/Rect.html

[brazen ice]

Heya, is anyone familiar with an approach to cast "smaller" shadows in a 2D Top down setting? Currently shadows cast shadows as far as the light distance. Instead to simulate height in a 2D Top down game it would be nice to be able to cast smaller shadows the closer you get to the light source.

[modest cargo]

In 2D URP shadow casters can only cast infinitely tall shadows
You can tweak normal map distance per light to get shorter shadows, but only on normal mapped surfaces, not shadow casters

[frozen osprey]

that sounds like a job for true 3D lighting

[modest cargo]

There are also third party assets for 2D lighting that can handle those cases
Personally I might go with fully 3D lighting since that's what Unity is best at

[brazen ice]

How would that work with sprites? I would like to maintain Pixel art style art

[modest cargo]

You can use pixel style sprites but you'd have to treat them as 3D geometry for the sake of shadowing

URP doesn't support Pixel Perfect Camera without the 2D renderer, which in turn doesn't support any 3D lighting unfortunately
So that combination would be restricted to built-in render pipeline
But you don't need the Pixel Perfect Camera for a pixel style

[brazen ice]

Aha I see, I have a tool called Kenney Shape that can turn pixel art into 3D objects. But how would I go about having spritesheet animation for such 3D models?
Simply make all the parts of the spritesheet then quickly switch meshes or?

[modest cargo]

I suppose you would
That means you get shadows from actual 3D meshes and don't have to deal with sprites at all

[brazen ice]

Never done 3D, is there a term for this kind of "shape shifting"? Usually what I have seen for 3D is things have bones that you then can animate as you see fit.

Otherwise another approach would be to draw a shadow and simply resize/rotate depending on how close you are to light sources

[modest cargo]

They usually have bones yes
You should be able to animate the mesh filter component's mesh reference just as you would a sprite renderer's sprite reference

[brazen ice]

hmm, it did not allow me to drop it into the animator. I will take a look at this more tomorrow

[brazen ice]

Thanks

[modest cargo]

If the property cannot be keyframed, I expect you should be able to make a script component that sets the mesh reference from a serialized array, then keyframe that array index

[brazen ice]

Alright thx, that's a good idea. Little bit tedious for multiple animations but maybe worth the sacrifice for better light/shadow 😄

[modest cargo]

If the component is set up well it should be just as quick if not quicker to animate the index rather than explicit asset references

[solemn latch]

For such low resolution objects you could probably just use a cuboid shadow caster?

[brazen ice]

I am not familiar with this and google is not very good at telling me what cuboid shadow caster is.

[modest cargo]

Meaning you could make the shadow casting part by scaling cube meshes and use minimal to no animation for them

[rich crest]

is there a way to get like discount for photoshop

[solemn latch]

It is a cube roughly scaled to the shape of your sprite and set to 'cast shadows only'

[brazen ice]

But this is still in the 3D world right? I can't mix both 2D and 3D?

[modest cargo]

You can, and I assume in this case you would mix 2D and 3D
Otherwise if you use 3D meshes for your characters you can cast shadows off of that mesh without worrying about separate shadow casting geometry

[errant surge]

where would be the best place for downloading / commisioning tilesets for LDTK

Hello, I'm trying to understand how the tilemap feature works in unity and how to put tiles on the map, and not only I can't reasonably select and move tiles on the tile palette (they just select randomly no matter what tile I select, when I try to move them they move in chunks and stuff like that), when I try to paint with them on the actual scene the actual tile is miles away from my mouse cursor and this makes no sense, what should I do to solve this?

[solemn latch]

Are your tile pivots correct, and the sizes/ppu matching the tilemap?

[sharp spire]

Hey guys what would be the best tool to use ti create pixel art and a game

[thorn turtle]

i personally use aseprite

[sharp spire]

Yeah i have heard thats good is it for free

[thorn turtle]

afraid not

although i wouldn’t be surprised if it was on sale on steam, since the holiday season is coming up

[sharp spire]

It is on sale but too much for me to get atm

[thorn turtle]

sorry to hear that, my prof mentioned this pixel art website but i haven’t tried it out myself

https://www.pixilart.com/draw

i’m not sure how well it works, so you’d have to do additional research

hope you find something that works for you!

[sharp spire]

This could work thanks

Will give it a look

@thorn turtle you any good with pixel art

[thorn turtle]

i don’t do much pixel art unless it’s for school

i mostly do regular digital art

[sharp spire]

Ok understand thats all good

[random plover]

Is anyone available to help me out with something?

[solemn latch]

Can you be any more vague?

[sinful grail]

https://dontasktoask.com/

[warm cliff]

it is free, but you have to build it yourself

you either pay for the pre-built .exe (just click and install) or build it yourself (took me 20 minutes) and install it

[errant surge]

I'm looking to get into making some levels with LDK,
does anyone know / have any example tilemaps i can practice with before I buy some / create my own

[modest cargo]

LKD?

[modest cargo]

@errant surge Kenney has plenty of tilesets
https://www.kenney.nl/assets
Many more can be found on OpenGameArt
https://opengameart.org/

[errant surge]

So from my understanding, you'd use a map like this for the basic ground textures
and then a second, seperate automap for the things like cave walls... is that right? or can/should you use automapping for the floors as well

[modest cargo]

There's many ways to go about it technically
Unity only handles tile rules between two tile types per layer (or tiling rules between filled and empty space, to be precise)

[mint flower]

Im making a game, and i finished the first level. So i move on to the next level, but all of a sudden my player prefab is invisible and it retroactively turns my player model on the previous level invisible as well. None of the enemy models or anything but the player were affected though and I can still move through the level like normal. It also is only affecting it when im actually playing the game, not while its in the game or scene tabs. Anybody know what could be causing this?

im not sure this is the right place to post this but i can only assume theres a tool idk about or something that i accidentally activated. Im very new to game development.

[echo pagoda]

Hey guys, need some advice, I want to build game boy Pokemon game like(sort of tile pixel 2d game) , but I know nothing about Unity right now, I was wondering weather it's better to go for unity or other tools like flame with flutter

[frozen osprey]

do you mean that every time you play the game you start visible but become invisible once the next level starts? or is the player now always invisible since you’ve began development of the second level?

a possible explanation for the discrepancy in scene tab vs game is that you have the player’s z set too close to the game camera so it’s not rendered anymore

[modest cargo]

The camera might have a different Z position between the scenes

[mint flower]

Always invisible from the start.

[modest cargo]

Since it looks like both engines can easily handle what you need it to do (sprites and 2D tiles) it doesn't really matter which one you use

Whichever coding language you're more familiar is likely the better choice

[harsh ore]

Hey , does anyone have any good tips or tools on how to deal with the sorting issues as seen here?

[mint flower]

the camera is at -10 and the player is at 0 on the z axis so it should be showing up

[finite beacon]

i was just fixing that as im tinkering with tilemaps in unity. I just made another tilemap layer and paint areas where I move the Z value around to get around odd sorting issues. dunno how it will workout in the long run but its a quick and easy fix for now. blue areas are temporary offset spots, red is colllision :

[solemn latch]

Custom sorting axis based on the base of the sprite would probably get you a lot of the way there.

[hot kernel]

hello guys, im trying to either generate or use a ready 2d (pixel art) world, i am doing a project for a course and can't find an easy way to do it, is there an easy tool for this situation?

You'll probably need to provide more details. What is a ready 2D world exactly? What do you need this world to have? Is it sidescroller? Top down?

Tiled is a popular map editor with its own format and there are unity packages that allow importing them.
Sample Tiled maps:
https://github.com/jamesbowman/tiled-maps
SuperTiled2Unity:
https://github.com/Seanba/SuperTiled2Unity

[lime depot]

How to reuse those tiles without editing the tilemap itself in RuleTile?

To make it more varied.

We are speaking about RuleTiles

[modest cargo]

The middle icon can be clicked to allow tiles to be used in places where they would fit if rotated or flipped

[lime depot]

Yes but it only works if the tiles on tile sheet is facing the same direction?

[modest cargo]

Ah, you're right
Even if rotation is allowed, it's used only when necessary, when a tile of higher priority doesn't replace it
So the orientation would have to be the same on the sheet, and all the options listed in the Output array

[next sluice]

hey all, i seem to be having trouble with understanding rule tiles and how to use them for my game. I have a rule tile for all my "wall" sprites, and i want to have specific North, South, East, and West walls, as my game is top down, but from a slight angle, like SmashTV or the 2D Pokemon Games. the playable/walkable floor of my level is on a separate tilemap from my wall, and as i understand it, regular rule tiles can only look for tiles on the same tile map, so im a bit lost on how to seperate north and south walls, and east and west walls. Any ideas on how to accomplish this?

[still tendon]

Hi all
I was trying to make my shadow affect the lower grass tile map
Image
Like the rectangular grass under the garden bed
I toggled the sorting layers
And editted the shape
And changed the intensity
But for some reason this issue occurs when i target sorting layers
I don't want the shadow to cast anywhere else, only from the garden bed to the grass below it
It only works when I toggle the sorting layers to be everything
Here are my sorting layers

I want the shadow to be from the inner grass onto the dirt, here's how it looks when the shadow is applied to all layers:

When I set the layer of the shadow to only affect GrassBed (Grass around the garden), it does this:

When I do the inner grass it seems to do nothing, but i want it to only affect it:

How do I achieve this?

[still tendon]

Forgetting that

Why are the shadows on my scene view different to the ones in game view?

And how do I avoid this?

[modest cargo]

I'd check that camera type is orthographic, and that there's no weird depth position or clipping plane values that could be causing something to cut off

I don't use 2D lighting a lot but I usually saw similar issues with scene viewport related to zoom/clipping planes, but not the other way around in game camera

[modest cargo]

@still tendon if this is the effect you want, all I had to do was to place the cyan sprite on a new lower sorting layer and then exclude that sorting layer from the red sprite's shadow caster target sorting layers

[next sluice]

Just bumping this a bit

[modest cargo]

How tall are the tiles? In my mind it seems you could be asking about how to make basic rule tiles, or how to deal with fake perspective tiles that reach multiple tiles high

[next sluice]

All my tiles are flat, it's a purely 2d game

So yeah I'm asking about basic rule tiles

[modest cargo]

Can you show what you have so far in terms of sprites and rules

[next sluice]

I guess I just can't figure out the logic

[next sluice]

Yeah I can in a minute

[next sluice]

excuse the crude graphics i have atm, im just doing some testing.
red = north
light blue = south
green = east
yellow = west
rn im just experimenting with 4 tiles and will worry about diagnols later

[modest cargo]

Sure that works
Usually you have solid walls instead of hollow ones in an enclosed level, but there's nothing wrong with this way

Remember that when tile rule evaluation is successful, it stops checking, which is why you never see light blue or yellow walls in your example

[jaunty echo]

anyone can tell me more on raycasting

[thorn basin]

Hey, I have a small weird problem with a tilemap collider using a composite collider. So Mario can wallslide if he detects a wall on the left or right, which works well when sliding against a left wall, but it glitches on a right wall. This only glitches if he is sliding on this tilemap/composite collider, but not on a normal boxcollider2D. The bug causes Mario's state to constantly switch between wallsliding and falling. The colliders are all on the same Layer and I use raycasting for custom collision detection.

Here is a video showing the problem. The white wall uses a boxcollider2D, while the Mario tiles use a tilemap and composite collider:

[sinful grail]

This is a code question most likely. Not a 2d tool one for sure

But what do you want to know?

[jaunty echo]

well trying to figure out how to make a glass light reflection and something like a time of day system

and coloring for what would be the best setup for a gold glass like reflection

[sinful grail]

Are you wondering about rayTRACING then? You can use raycasting for what you mean too, but just wanna make sure

[jaunty echo]

well raytracing but 2d

as raytracing 2d doesnt looks like it exist

[sinful grail]

It does

[modest cargo]

It just doesn't much look like 3D ray tracing as there are no "surfaces" that we could see

Thank you Spazi

[jaunty sequoia]

is it possible to make shadows complete dark

[worthy holly]

hey, im now to this and i have a question. when making tilemaps and palettes and trying to use them in unity,

1. why the red outline
2. do they have to be a certain size to fill the square? i have mine at 48x48 px, but it doesnt fill it

the red outline didnt appear a moment before

also i cant move the camera anymore

[worthy holly]

on the subject, in the sprite editor the option for slicing is blacked out, so i cant cut it into 9 16x16 squares (i wanted to try something but still)

[modest cargo]

A shadow is an area occluded from light
If you have no global or ambient light, the shadow is totally dark

[meager belfry]

Hey everyone! I have a question regarding Tilemap alignment. I've set up a Tilemap with a cell size of 256x256, but some of my assets (e.g., bushes) have different dimensions like 413x166. What would be the best approach to align these non-square assets with the Tilemap effectively?

[modest cargo]

Slice them from the sprite sheet by cell size / count and assign a custom pivot if you need to offset them

You don't really have to worry about getting "empty space" in the slice since the sprite outline cuts it out in sprite mode: tight

It looks like the plants have random vertical offsets even if they're on a grid, so you may have to adjust the pivot point manually for each

[vague smelt]

Can i make my walls not be lit up by light if it is coming from above?

[modest cargo]

Shadow casters with self-shadowing enabled I guess is what you're looking for

2D light has no concept of "above" though

[vague smelt]

yes but sadly this doesn't work for me

is there any way using masks or normal maps?

[modest cargo]

I guess I don't understand what the goal is
What's "not working" here?
Is this meant to be a side view or a top-down view?

[vague smelt]

i need to light be lighting up the wall if it is under the sprite but not if above so it looks 3d

[modest cargo]

I have hard time parsing visually what's wall and what's floor, looks like just yellow rectangles
Anyway I think you could use normal maps if you don't want shadow casting specifically as shadow casters are infinite in height
A normal map can be "angled" so it would receive light from one direction but not others
If that fails I guess you could also get a similar effect by splitting point lights into two 180° spots with different layers

Probably achievable with normal mapping though

[next sluice]

Yeah, but idk how exactly to set up the rules to get seperate north and south walls... Its confusing me a bit

Sorry for the late reply, yesterday was a bit busy

[modest cargo]

With hollow walls you cannot
But if you swap to solid style that I mentioned then it becomes simple

[next sluice]

What are hallow walls

[modest cargo]

By hollow I mean you're only tracing the edges of your rooms

Instead of having all the space outside of the interior be wall tiles

Hallowing is something else entirely

[next sluice]

Oh

[modest cargo]

So your north wall checks if there's blocks next to it horizontally, but also if there's one above it

South wall checks if there's one below

Horizontal walls that have space above and below them do not know if they are north or south

From their perspective they could be both

[next sluice]

Oh I see

Is there no way to somehow check floor tiles instead of only being able to check for other wall tiles?

[modest cargo]

No built-in way
The normal tile rules only check for presence of tile on that tilemap vs lack of one

[next sluice]

[jaunty sequoia]

thank you

[next sluice]

So basically I wanna make my walls 2 blocks thick or something?

[modest cargo]

Yeah but you might as well fill the void with wall blocks
Unless you want "outside walls" also

[next sluice]

Nah but idk I feel that looks ugly

Tho what I could so is if a wall tile is surrounded by other wall tiles, then I could make it a blank/transparent sprite so it looks about the same

[modest cargo]

What do you need it to look like? Are these both interior and exterior walls?

[next sluice]

It's for a game that only has dungeons so it's all interior walls... I guess?

Sorry I kinda don't understand

Hold on

This is the look I'm going for

In terms of the wall and floor sprites

See how the walls have north and south sprites?

[modest cargo]

Yeah, the walls are filled in as I described

[next sluice]

Well actually I've seen this tutorial series, and the guy did it using some weird algorithm that uses structs full of binary values, he didn't use rule tiles. Someone in one of the comments said that they achieved this same effect using just rule tiles tho, which is why I'm doing it with rule tiles

But idk how the commentor implemented their rule tiles, maybe they filled any void space with wall tiles

[modest cargo]

I don't see why not

You don't need empty space outside if it's a dungeon

[next sluice]

I think the way the commentor phrases their comment, it insinuate that they didn't make any changes to the code

[next sluice]

BTW idk if this changes anything but the dungeon is procedurally generated

[modest cargo]

No, you just have to consider the filling when generating
Maybe "carve" rooms instead of simply lining them with walls but whatever works

[next sluice]

Eugh, that sounds like a big change to my algorithm over wanting some nice wall graphics

[hot brook]

It's the axis that is used for sorting. So for RPG like perspectives in 2D, you want it to sort by the Y-axis.

Make sure you have the pivots of your sprites in proper places (like at the feet), and set the sorting to pivot mode on the sprite rendere.

[hot brook]

Yes ok but I don't understand how it works🙈

[abstract olive]

The sprites are sorted by the axis. In this case whatever is lower down on the y (bottom of the screen) are rendered above things that are higher up.

It uses the pivot to calculate the position to determine the sorting.

[hot brook]

Aaaaaahn okok now I understand!🤩
Thanks a lot

[hot brook]

One last question, so the "Transparency Sort Axis", is the values that calculate the distance between each sprite's pivot?

[abstract olive]

It's the direction that will be used to order the sprites

[orchid crane]

I have a question about this. I have a tileset with a tilemap collider2D, and I place trees scattered throughout the map. Is there a way to make it work well? Because for sorting layer, the pivot position is taken into account, and some trees may be above and others below the pivot of the tilemap. I have opted to make each tree in a separate tilemap or to insert them as game objects. This corrects the problem, but it is not very practical.

Sorry my poor English

[torpid night]

in general, multiple tilemaps are a good idea for separate layers

it’s fine to have like 20 tilemaps if you need. you just don’t want to go overkill because you usually do want to group things together that should be mutually exclusive and in the same “layer” of the game

[solemn latch]

Those definitely are words?

[still tendon]

My words. Thx for asking.

[final imp]

How would i remove this orange outline? i need sprite selected but it is in the way of editing shader

[snow loom]

Hey!

so, I've got a sprite shape with a tileset I've made in mind, but there keeps being a gap between the fill & the outline & I've tried EVERYWHERE & I can't find a solution

[snow loom]

please help :D

[snow loom]

fixed

apparently sprite shapes really get angry if you have the outline be thin in the sprite itself

So, I have this simple sprite I split into multiple parts in sprite editor and now I want to use skinning editor (I am completely new to these tools, only watched a few tutorials)

How can I assemble my character to begin rigging? (You know, put the body parts together)

(ping me if you respond)

[barren anvil]

well, I found this, but how do I do that?

when I rig it

and then select the leg for example

the bones are connected only to the body

[meager belfry]

Hi everyone, I would like to ask if you know how to deal with such an uneven TilemapCollider2D? It's causing issues with my character's movement, and it can't bounce off the walls properly. I've tried using CompositeCollider2D, but then my character goes through the floor. I don't know what else to do about it. I noticed that everything works fine when I use BoxCollider2D for my character. Additionally, besides the previously mentioned issue, my character occasionally seems to get stuck in one place, and only after jumping can I continue moving. I'm not sure what causes this because sometimes it stops, and sometimes it doesn't, even in the same spot."

[lost pond]

what do you mean by uneven

if you want to manipulate the shape of tilemap collision you could try to go to the sprite editor and change the mode to custom physics to manipulate the collision body. Remember to reset the tilemap collider after you update the physic collider

[meager belfry]

I mean that this TilemapCollider2D seems to create an outline of the Tilemap, and the Sprites appear to be uneven by default, causing issues with my character's movement. CompositeCollider2D improved these outlines to make them even, but it also caused the character to start passing through the floor

[meager belfry]

i will try thank u

[lost pond]

np if you have any problem you can ask

[meager belfry]

Good to hear that, because I still have a bit of a problem XD. I don't fully understand how it works because I changed the Sprite Editor to custom physics as you said and reset the TilemapCollider2D, but I have no idea how to change these colliders now, especially since they should be perfectly straight. So far, they still seem to be aligning with the texture. Do you have any other ideas or could you tell me what I can do about this?

[lost pond]

you click on each tile then click on generate, change the shape as you want, and then apply. reset the tilemap collider afterwards

theres a documentation on unity you can read

[meager belfry]

thanks, done, ive change rigidbody2d to kinematic; colision detection to continous; interpolate to interpolate and than add CompositeCollider2D and adjust collider to my grid, everything works fine

[solemn latch]

Disable selection outlines in gizmos

[solemn latch]

That example was for sprites that are all on a single layer.

[barren anvil]

Oh, anyways I finally figured out what was wrong. Thanks for the help anyways

[proven island]

Hi, my background image dissapears when I switch from Full HD to Free Aspect. I couldn't find any fix online.

[modest cargo]

Is your background image a sprite or a canvas object

[proven island]

When I click play in Full HD :

[modest cargo]

Canvas so it's #📲┃ui-ux stuff rather than 2D
Anyway, the scaling settings of the Canvas component and the anchor settings of each canvas object determine how they adapt to different resolutions and aspect ratios

[proven island]

I'm so sorry about that wrong category

[modest cargo]

https://docs.unity3d.com/Packages/com.unity.ugui@2.0/manual/HOWTO-UIMultiResolution.html
This looks like a full guide

[proven island]

Thank you

[snow shell]

Is there anyone here who has a clue about parallax backgrounds? 🙂

[abstract olive]

Sure, move the layers at differing speeds. Parallax achieved.

[warm citrus]

Anybody can tell me why are my 2d sprites getting blurry while im walking around

If i put camera inside my player so it follows him as he moves, he will not be blurry, but everything else will

[modest cargo]

Known to be a side effect of using smooth camera movement together with pixel snapped sprites
Don't know if you're doing either of those things tho

[finite harbor]

how do i set it up so if i click open on an image in my assets collection, it opens up aseprite

seen some youtubers do it and i have no idea how to set it up

[modest cargo]

I think it uses whatever program you have set as the default for that filetype in your operating system preferences

[finite harbor]

ok i figured a workaround

just have the project files open in file explorer and open them in aseprite

they update with no problems

[meager belfry]

Hi, does anyone have an idea how to solve this problem? the character seems to run into the wall when turning around and I have no idea what's causing it

[solemn latch]

Is the pivot in the wrong place?

If she is pivoting around her front, then flipping will teleport her into the wall

[flat dagger]

Maybe you accidently moved the character on the animation, or perhaps you have a collider on your sprite, changing it's scale can move the collider along with it.

[meager belfry]

Sorry that I haven't been here for quite a while, but I took a break and completely forgot that I wrote this. However, you were right. Now, I tried doing something with the pivot, and indeed, it was about it not being well-adjusted, causing the character to move strangely. Now, it feels even better to play with it. Thank you for your help.

[solemn latch]

Glad it helped 😄

[proven oxide]

anyone here use aseprite because i made a image in aseprite and im struggaling adding it to unity
this is the image in aseprite and i have the clouds saved as a different image so i can have them move seperetly from the background but when i import it to unity i cant get the size and position right

thats the best i have gotten it in unity

[white helm]

Might be Pixel Per Unit in images settings, set both to the same amount
You can also try following these settings since it's also for pixel sprites

I have a question, I'm not sure if that's the right category but still-
I'm trying to make the player appear as a shadow beneath the leaves via sprite masking but I'm facing a problem. I can't animate mask sprite, is this possible using animator? I have frame animation, so rn I'm stuck with a simple sprite mask over my animation

[swift wind]

Hey all, I'm having an issue where my sprite in my 3D scene is much darker than it's actually supposed to be (see sprites below it). Is this due to working with URP or is there something else that I'm doing wrong? I've made sure that the light source is pointing directly as it in case that was the cause

[modest cargo]

What materials are the sprites using

[swift wind]

Oh I went to check and realised that I had a color applied to my sprite, which was making it darker 😅 oops

I had selected a darkish gray

[modest cargo]

That explains it
Note that sprite shaders do not receive any lighting, and lit sprite shaders only receive 2D lighting that requires 2D URP renderer
3D lit shaders may not support all sprite features properly
URP as good as it is for many purposes, may be a bad choice if you want to mix 3D and 2D because it attempts to separate the two

[swift wind]

Oh thank you for the heads up. My idea right now is to create a game with 3D environments and buildings, but 2D characters. Would you recommend going with the default Unity pipeline instead?

[swift wind]

Or is there a different option you'd recommend?

[modest cargo]

The choice might not make a difference
If you need to use pixel perfect camera component at any point, or have the sprites be lit by 3D lights, you may prefer the built-in render pipeline because it offers more options for those

For now I'd say do tests for your visuals and keep the option of switching in mind if you encounter issues
You can ask here more about them if those become apparent

[swift wind]

Thank you. I may not need either of those, but something I might want to do is to at some point have sprites reflect in 3D water. Would that be possible with URP?

[swift wind]

Okay awesome, great idea

[modest cargo]

That's not an easy task
You'd have to 1. use a shader that utilizes Scene Color information, which may be simplest and cheapest but it cannot do perspective and only works on opaque shaders which sprites normally are not
2. Use render target texutres, potentially with another camera to capture and draw an inverted view of the scene onto water material
3. Implement planar reflections, which is like option 2 but with extra code to offset the RT camera to give the reflections proper perspective
4. Implement screen-space reflections, BiRP supports this natively while URP has unofficial support for it, tends to suffer from rendering artifacts but otherwise is cheap and at least in BiRP is easy to implement

In any case you'll want to decide if you're "working in 3D while implementing 2D things" or "working in 2D while implementing 3D things" and try to solve every problem from that perspective

Even if you don't fully know at this point it's best to stick to one
In my experience it may be tempting to swap when you run into the limitations of either workflow, but swapping is a bunch of work and ultimately trades 2D problems to 3D problems or vice versa

[wary vector]

is there a good free programm for pixel arts? For 2d map design

like Piskel

[swift wind]

Sorry for only responding now, but thank you so much for the help. I think my idea right now is "working in 3D while implementing 2D things". I'll stick with URP for now and if there are complications down the line then I'll just handle it then.

[swift wind]

I believe Aseprite is free if you build it from source code.

https://www.reddit.com/r/PixelArt/comments/i387m1/guide_how_to_build_aseprite_from_source_aseprite/

[wary vector]

oooooh wow THANKSSSS

[wary vector]

what is the best way to make a building? In one big part or in many small parts?

[empty quiver]

Anyone know why this is happening?

[foggy horizon]

Hi all, anyone familiar with Sprite Shapes?

I used this sample
https://assetstore.unity.com/packages/essentials/tutorial-projects/dragon-crashers-2d-sample-project-190721
The river used to be a train track, which came with a set of diffuse main texture, _Mask, and _Normal texture for the tracks
I'm only able to change the main texture, while the _Normal (at least, seen from the screenshot) is still applied
Tried switching to "debug" inspector, but still can't find any slot to change the other texture maps

Original set of textures

[solemn latch]

The additional maps of a sprite are set in the sprite editor

I've not messed with secondary maps in sprite shape but if it is using the sprite data that's where you edit it

[empty quiver]

I'm using Unity 2022.3.15f1 and I'm really hoping I just did something wrong and this isn't just an uncontrollable glitch

[foggy horizon]

Hi all, anyone know why my 2 png are imported to unity with a... weird resolution scaling?
They're both 40px per unit
The only difference technically is, the house is part of a split bigger sprite, while the rice plant is a single sprite used whole

Between the house and the giant rice plant on the left

[modest cargo]

Most likely the plants have been superscaled before importing so sprite pixels don't match actual image pixels

Or it has a bigger transform scale

[acoustic burrow]

hi some tiles in our project lacks collision. and it seems to be related to the rule tile itself. since even if i change the sprite and update the colliders by placing new tiles it still lacks collision

the tiles that lacks collision are made with newer rules (as we had a functioning rule tile, and then added som more rules later) and those new rules lack collision

nvm, was grid / none problem in collider

[shell igloo]

Would be able to ask a question about graphics on this channel?

I haven't found i should ask those

It's basically about why the game looks so distorted sometimes

[sinful grail]

Which graphics? There is a whole graphics category with
#archived-urp
#archived-hdrp
#archived-lighting
#archived-shaders
#💥┃post-processing
#✨┃vfx-and-particles

[shell igloo]

uhm i have no clue im sorry im new to this things

[sinful grail]

Ah, this is probably the right channel for what you're asking

[shell igloo]

Thank you :)

[sinful grail]

You'll want to show the sprite import settings

[shell igloo]

that's for the tiles for example

[native tide]

hey guys

So, this is the og image

but when i export it to unity

[modest cargo]

Likely your game window's preview zoom level is not 1x, but less or more so it has to stretch or squash the pixels

[native tide]

this happens

its neck get all messed up

im not an artist, im more used to the coding part, so I really dont know much about exporting

[modest cargo]

In import settings Compression: none

[modest cargo]

Fear not, artists know even less about this side of the art asset process

[native tide]

ty so much

[shell igloo]

it still looks kind of bad

[modest cargo]

That's a different issue

Resulting from a lack of padding in your sprite sheet

Judging from the distortion the zoom level may still not be right
Might also be that your sprite PPU is wrong
If you want pixel perfectness you must use the pixel perfect camera component

[swift wind]

What's the best way to programmatically change a Sprite object's sprite?

For instance, I have a creature object that has a sprite child object. Based on what kind of creature it is, I want to change the sprite to match accordingly.

[nova tinsel]

is there a way i can avoid the aseprite importer modifying the dimensions of my sprite?

the sprite itself is 32x32 in aseprite, but the immporter sets the dimensions to 64x64

[nova tinsel]

i just embedded the package itself and modifiedd it to get what i needded, would be very cool if something like this to avoid the image packer for small, texture sprites was part of a future update

lol nvm it ddoesnt work if your sprite doesnt encompass the entire canvas

ugh

[hallow fox]

Hey guys, just a question about sprites here, I can’t seem to be able to splice this specific sprite sheet. Since it’s unevenly aligned I can’t splice by grid and the automatic splicing doesn’t want to work either. I’m really set on using this artists sprite sheets as I really like the style (and I was going for a Halo inspired game) . Another question I have is about the background- how would I go about with this sprite sheet/sprite atlas when it’s backround isn’t transparent? Also FYI I’m doing this on my school computer only (because I don’t know how to go about the hassle of getting a license for my pc at home) so I am limited to say the least. Thanks for reading

[swift fox]

is there a way to sort sprite sheet images?

after slicing this is what I get

[modest cargo]

No real way around it except getting a properly aligned sprite sheet, or slicing manually
The background must be removed in an image editor
You'd prefer to be working with proper development assets instead of rips
If you mean Unity license you can get one just by signing in

[modest cargo]

Yes, when you click on a slice you see its information in the sprite editor
There you can set its name, and the slices will be sorted alphabetically in the project window based on that

[swift fox]

Got it, Much appreciated !

[wild galleon]

after 2 and a half days of bashing my head against a wall... i finally made my first tilemap

now i have to find the tutorial to figure out how to make them do things when clicked

wish me luck guys

[modest cargo]

If you can tell what things it needs to do it may be possible to provide some directions

[wild galleon]

basically i want a sort of menu to pop up when a tile is clicked, with options to build, harvest, etc

i know i have to put some scripts and stuff in

gonna poke around google while i make some pizza

[modest cargo]

That takes many features working together, best cut it into smaller challenges

[wild galleon]

Yeah that sounds about right. I'm working on just making the tiles interactive. I can add the specific interactive buttons/features later I just need to start with the interaction

I think that's where I should start, anyways, if you think I should start from another angle I'm open to ideas. I'm a complete beginner on this stuff. My only software engineering experience is a Java programming class from high school

[wild galleon]

Do you have any tutorials/source material/etc I should start with?

[modest cargo]

The Tilemap Extras package has importable examples for various things to do with a tilemap

One of them might've been related to clicking tiles to change them

[wild galleon]

Alright cool I'll mess around with that and see what I can see, thank you very much. Do you know if those examples also come with scripts?

[modest cargo]

They do
The samples tab is in the package manager on each package that has them

[wild galleon]

Big thankies

[wild galleon]

im learning so many big words today like "orthogonal"

[finite harbor]

i dont understand why my tilemap scaling went wrong

for optimal size and pixel consistency i want to use 10 ppu but it results in this

[modest cargo]

Your tiles are 16 pixels wide, and it looks like your character has much higher PPU than 10 (or a smaller scale)

If you want 10 PPU you need to author your characters and tiles with 10 PPU in mind

It determines how big they are relative to each other and you won't be able to change that later, without losing pixel consistency

[finite harbor]

ok that means ill have to redraw my sprites at some point

which i mean is fair

[glossy fox]

Someone have an ideas how to create shadow caster for Tilemap :?

[glossy fox]

I've found the solution by myself 😁 by just adding shadow caster 2d and set casting source to composite collider 2d

[stray ember]

Is there anyone who can answer my question?

[spring hill]

why is my sprite pixalated

[modest cargo]

Game window is zoomed in using the "scale" slider that's barely visible

[spring hill]

even without zooming in it seems off and pixalated

[modest cargo]

It's too small or its PPU is too large relative to camera size

[spring hill]

how to fix dis?

[modest cargo]

Make the sprite larger, make its PPU smaller or decrease camera size

Nothing about the sprite itself is pixelated, it's simply too small to be represented by display pixels

[spring hill]

its too large, I fixed the ppu

but still

[modest cargo]

What does it look like after fixing it

[spring hill]

exact same

[quasi stag]

Pretty general question; Is it possible to have effects manipulate the environment itself? Maybe it makes sense to say on the renderer side. For example, a black hole that sucks in color.. the sprites themselves would be unaffected, it would just be an overlay effect. Or a ripple that goes across the camera overlay as a wave

[waxen token]

what is the best free 2D software for game art?

[modest cargo]

That's 100% subjective and depends on the type of game art you make

But I wouldn't miss an opportunity to praise Aseprite

[waxen token]

thanks for ur opinion 🙂

[modest cargo]

If you have clearer examples of the kind of art and assets you want to make, I can give more precise recommendations

[waxen token]

I really like smooth textures. Nothing realistic, I love quaint artwork, that look kinda cute-ish

this is an example of something i quite like

obviously not massive detail but you get the jist

or this

[modest cargo]

This one has extremely densely packed visual details and texturing, even if it doesn't make much sense at places
That happens with AI generated artwork like this, so I can't point to any specific real techniques
People usually use Photoshop to make art that closest resembles this, using digital painting and meticulous rendering of surfaces and light

[waxen token]

Awesome, before I can afford photoshop what would you suggest is the best to learn for free

[modest cargo]

This style on the other hand requires much less rendering due to relying on solid colors and gradients a lot, so in addition to Photoshop you can get by with digital painting oriented programs like Clip Studio Paint and Krita

[waxen token]

Legend, you really know your stuff

[waxen token]

does anyone know if you can use a Wacom One with Krita?

[open oracle]

Big Krita fan here. And. Yes.

[waxen token]

amazing jusr what i want to hear!

[weak mountain]

Hey guys, its me again. I'm using a super simple script to have my 2d character face/rotate towards the mouse position

Vector3 mousePos = Input.mousePosition;
mousePos = Camera.main.ScreenToWorldPoint(mousePos);

Vector2 direction = new Vector2(mousePos.x - transform.position.x, mousePos.y - transform.position.y);

transform.up = direction;

However, it causes a lot of jitter with the player camera. Any advice on how to fix this?

[solemn latch]

Where in the frame are you running this code, and how are you handling your camera?

[opal delta]

I'm making my level in reference to being on a 1920by1080 screen, however, if i switch to a different screen size, the borders i have set change, how do I account for this effectively?

[amber ice]

hey guys! for some reason my 2d sprite has a white line over it sometimes. anyone have an idea on how to fix this?

it goes away when i disable gizmos

nevermind

i just had to unselect the player

[weak mountain]

It’s a Cinemachine virtual camera and this script is being ran in my player movement controlling script

I believe the issue is that the player himself is jittering as everytime he moves, it rotates a bit to update and face the mouse position. If I solve this I’d likely fix the problem but I’m not sure how to go about it

[solemn latch]

I meant, in update, fixedupdate? And when do you have the cinemachine camera updating? Generally you want the camera to update after all character movement if you are following the character.

[strong island]

hi guys! I am using the aseprite importer for my tileset, but i have seen that I have version 1.0.1 which doesn't support custom physics shape for each tile, but a newer version (1.1.0) has it. The thing is that I am not being able to update it, does anyone have any idea about it?

[lost pond]

Just a programmer learning to draw

I need some help with shading and shaping

can someone give me some feedbacks?

I want it to be a top-down sprite if you wanna know

[modest cargo]

Different screens (and frames if on browser) have different aspect ratios
Unity normally matches camera height and screen height, and adjusts camera width to fill the screen width

There's probably some way to flip this behaviour to match width if needed, but in either case you need "safe areas" on the horizontal or vertical borders of the scene

[light elk]

which tool is used to make this red mask map in unity in the happy harvest demo?

[opal delta]

I ended up just making it so i use screen width clamps

[modest cargo]

It looks like the normal map ran through a step function to isolate the highest and lowest values meaning the ones with the sharpest angle
Not sure which tool specifically, a lot of them can do that

[solemn latch]

They could have just drawn it.

[swift wind]

Hey guys, I have a ScrollView (DeckComponent) that contains 8 card rows. Everything seems fine except for the fact that the scrollview doesn't scroll, it just keeps bouncing back. Any idea why this might happen?

The "View" in that tree there is an image with a mask

[tall sapphire]

send your components

[trail bramble]

The "Content" object is most likely not scaled enough to fit all of the cards. You could do this manually, but a more scalable solution is to do it automatically. For example, assuming the CardRow objects have a horizontal layout group, you could attach a vertical layout group to "Content", paired with a ContentSizeFitter that has the vertical scaling set to "Preferred size" to make it fit all the card rows inside it

[hollow crown]

They go into detail about it in, and everything else this e-book
https://unity.com/resources/2d-game-art-animation-lighting-for-artists-ebook?ungated=true
Though you can see they made it manually out of vectors on page 26

[tidal river]

i guys im looking for a good rpg dungeon assets for my game anyone know something?

[sullen copper]

Question about 2D (not sure where else to put this). I'm sorting layers by pivot points, but I'm not sure what to do about the trees in my world (using tilemaps, btw). If I put the trees in the world as a separate tilemap layer, they don't really have pivot points right? Right now, I've separated all trees into 3 different parts so it sorts correctly, but it still has kinks, and I feel like that's not the way to do it. Is there something I'm missing?

[modest cargo]

There are "gameobject tiles" that may solve the pivot problem
Once it's solved you probably don't need to separate the trees into parts

Unless the top part is so big that it can cover sprites that are "in front" of the tree

It's not uncommon to have the trunk and leaves as separate sprites

[sullen copper]

Yeah rn the trunk, tree itself, and then the leaves are all separate on different tilemap layers

the trees will never be cut down or anything

i just need them to be able to be walked in front of and behind

[deep citrus]

I need help with tilemapping

i got no idea what im doing and not to sure what i should be using

[open oracle]

as in - using the 2D tile system?

[open oracle]

https://learn.unity.com/tutorial/introduction-to-tilemaps

[deep citrus]

yes, im not gonna lie i just spen 1 and half figuring it out

[deep citrus]

the issue was it was a tile set and not individual 64 x 64 tile

[open oracle]

No lie, that's what a LOT of us do when we're new to something. You should have seen the mess I made of using the new input system

[open oracle]

well glad you got it

good luck with your project

[sharp raft]

Does anyone know how to make the tilemap collider just be a box instead of trying to fit the sprite?

[finite beacon]

click on the tile prefab in the project window and you'll see a collider type option in the inspector that you can change to grid from sprite

[modern niche]

Hey does anyone know how to import things from Krita as it just doesnt show up

[sinful grail]

You just export it from krita and move it into the assets folder. That's it
You have to export to a supported file format too I guess

[chilly stratus]

I want to make a pixelated 3D visuals, do i use a 2D tool?

[modest cargo]

Do you have an example of what you mean

It doesn't sound like you mean having 3D visuals and then simply pixelating them

[chilly stratus]

Like chained Echoes

Gives 2D vibe

While being 3D

[modest cargo]

The art of that game is 100% 2D
There's depth using an isometric perspective but that doesn't require 3D

[chilly stratus]

Oh, makes it a bit easier to do, thanks for the insight

[halcyon geyser]

Anyone know an alternate method for 2d pixel perfect? I tried using the Pixel Perfect Camera extensions, and it does what it's supposed to do, but it makes the camera's movement very jittery at slow speeds, and that stops happening as soon as I disable the component. I'm trying to recreate the genesis sonic games style in terms of how the game should be rendered. Apart from the 4:3 screen ratio.

[sand hemlock]

Wait, does the Shadow Caster in Unity ONLY work for editing the shape of each individual shadow? there's not one that automatically reads the shadow of the object and cast a shadow from it?

Would it be possible to add a dithering effect to something like this?

[sullen copper]

I have pretty big sprite sheets, and none of them are translating well to unity even though I'm keeping them under the 2048x2048 limit

sprite type is multiple, no compression, on point no filter

[oblique glade]

hey guys i am very new to all this and just doing this project to learn some things but in unity i got my little fella to move left and right with animations got my parralax setup (with my layers and the rate at which it moves bound to the Z coordinate of the layer when in 3d mode.) however one of the layers i would like to stay stationary or even LOCKED to the camera so it doesnt move at all AND i cant walk out of it. but i dont know how and i cant find anything on it.

[modest cargo]

What do you mean by "not translating well"

[modest cargo]

Parent it to the camera or use a script to set its transform inherit all motion by the camera's transform
Parallax effects usually mean in practice that one transform inherits a proportion of the camera's movement
This proportion visually translates to depth
Inheriting 0% makes it look like the object has 0 depth
100% makes it look like it's infinitely far away as it moves in sync with the camera
50% is somewhere in between
Negative proportions make it seem like the parallax layer is "poking out" towards the camera

[oblique glade]

ah sorry i already figured it

i should have said

my parralax was set up wrong

thank you though

i believe i will be here

VERY oftern

xD

off to work with me for now though

[sullen copper]

nvm im stupid i just needed to set the max size to 4096

[modest cargo]

I think the shadow caster inherits the sprite's physics shape when its assigned, or there's an option to, but I'm not sure
You can implement dithering using a Custom Lit Sprite -Shader Graph template, if you know how to implement dithering and have a general idea how to do that to the 2D light texture

[umbral flower]

how do i make an sprite of an png image?

i changes texture type but it wont show up as an sprite

[modest cargo]

Sprite type textures can be applied to Sprite Renderer components in the sprite field to appear visually
Clicking and dragging a sprite type texture asset into the scene automatically creates a gameobject with sprite renderer component and the sprite texture assigned
Remember to apply changes to the texture asset first

[sand hemlock]

No idea on that part. This is really my first time messing with the 2D sprite tools in Unity. Got any vids/resources on that?

[sand hemlock]

I'm using tilemaps and URP; I was trying to do the pivot point sort for the player VS the tilemap, but it doesn't really seem to apply as a whole with Individuals (obviously) and as Chunks it's considering the entire tilemap. How do I make it apply to individual IF my sprites are larger than one cell?

(just to show) my sprite sheet looks like this so when the character runs through the forest sprite or that pillar or cacti, since it's made of 32 x 32, despite 16x16 division, it's treated a bit "weirdly".
Is there a better way to handle this?

(Here's a recording of what's occuring just incase I'm being too obtuse)
Is the only solution to change my tilemaps, so 32x32 objects are on 1 map, 16x16 on another etc etc?

[sand hemlock]

oye, why am I seeing a sliver of the sprite next to the other in the sprite sheet below the plant decorations..? What's that about.

[sand hemlock]

Hm, I found someone telling me to use a Sprite Atlas, and used it and it seemed to work, but if someone wants to explain what exactly happened there I'd appreciate it.

[amber pasture]

I build a free tilemap editor that can export maps to Unity Tilemaps 🙂 lemme know if you want to try it!

[modest cargo]

These happen because the color sampling is a bit inaccurate at sprite edges and may incorrectly use the color of the pixel next to the sprite on the sheet, especially when not using Pixel Perfect rendering
The fix is to add at least one pixel of padding between each sprite
Sprite Atlas has a feature to add padding which is why it works
Aseprite can also do it when generating sprite sheets, but I don't know if the exporter package does it

[lost pond]

what is better tilemaps or sprite atlas?

can someone with experience tell me a little bit about it

[modest cargo]

They're not alternatives
A sprite atlas compiles all sprites to a single texture while keeping their slice / tile references
It's for optimizing draw calls and texture loads

[lost pond]

if in the future I want to make procedural generation is there any way to combine both tilemap and sprite atlas

for example a tree only has collision on its body but not the leaves and the tree must be counted as one object

but when I try to fit a tree into the tilemap

it isn't

every cell is counted individually

should I use trees as prefabs with sprite atlas instead?

[modest cargo]

A sprite atlas has no effect on how sprites work or how you use them
It happens entirely on the back-end

As I said it keeps slice and tile references

In unity tiles do not have to occupy just one grid square, but will if you slice them by grid

Your tree sprite can be a tile as just one big slice

[lost pond]

if I import the whole tree do I have to make another tileset for lets say 48x48 big things?

[modest cargo]

No
A tileset can use any sprite from any and all sprite sheets

But you may want to in the situation that you want multiple different grid sizes

If not, then no

I would have separate sprite sheets for different sized sprites/tiles just so I can use the same slicing settings for all of them

Otherwise it'll require manual slicing

Using a sprite atlas on top of that would just mean they get stored together in texture data

[umbral flower]

I clicked the png image, changed texture type from default to Sprite and I still cant select it as an sprite and when I try to drag it into the hierachy it doesnt allow me to

[modest cargo]

Probably missed some step, I'd assume
I'd look for tutorials or courses to see the process precisely

[spice geyser]

i have a sprite that i made a material and the sprite is not lookin like in aseprite is in 2d

[potent belfry]

sprite has a box collider on top and circle collider for the body + legs for smoother movement, for some reason it gets stuck on the wall when i jump into it, it wont let me jump again but i dont know why thats happening

the wall has a tilemap collider

[modest cargo]

Likely the corner of the box is getting stuck onto the corner of another box collider
The physics engine can't really figure out when the border of two colliders should be "seamless"
For that there's the composite collider component that should let the tilemap's discreet colliders combine together

[potent belfry]

what if i use an edge collider instead, make it 1 straight line?

[modest cargo]

Sure, but you'd have to do that for every wall manually

[potent belfry]

so do i get rid of the tilemap collider or do i keep it with the composite collider?

[modest cargo]

Keep

[potent belfry]

and how would i stop the sprite from sliding down the wall when i jump into it

like i want it to just fall down with no resistance

[modest cargo]

You can try setting a frictionless physics material, but it really depends on your movement code and how much they utilize physics

[sand hemlock]

Ohh. I didn't even know that was a thing. So the Sprite atlas then takes all the pieces and just adds that padding automatically, neat.

[potent belfry]

ive done that now the sprite is falling down but it still gets stuck sometimes when jumping up a wall

but it doesnt happen consistently

[modest cargo]

Hi, im trying to make one of those piano players in unity, but i'm running into an issue which i'm not sure how i should handle, im currently moving sprites to represent the note duration but the movement looks very choppy/glitchy?, and i don't know whats causing it but the sprites sizes/distances seem to be changing because of rounding errors? any help or pointing in the right direction would be appreciated :)

i don't know how well the video show the issues but you can see some squares that are paticularly close to eachother have their gaps change in size

[cold pelican]

There is a sorting issue in Unity? I thought this would be automatic
It flip flops between which is in front

Oh, ok. It is easily fixable manually. strange that they would include that in a tutorial project, but not mention it in the tutorial. maybe i just missed it when scanning to see if they covered it.

[quiet solstice]

Hello, I'm starting off on Unity by creating a 2d platformer and I want the player sprite to be a rectangle with rounded corners, anyone know how to do such thing? I've tried doing it in ms paint and visually it works but the hitbox is still a normal rectangle which I don't want

[solemn latch]

The hitbox will be determined by what kind of collider you use. If you want to use the sprite's actual shape, you'll need to set up the physics shape in the sprite editor. Otherwise, you can approximate the shape you want using box and capsule collider2ds.

[quiet solstice]

alright thanks

[little void]

Pardon me, I have what I hope is a very basic editor question:

How can I zoom in / enlarge 2D sprite keyframes shown in my Animation tab?

(I recently got a 1440 monitor. The animation tab depicts keyframes at their native size, which means for me they're... less than half a centimeter tall.)

[sage girder]

this has probably been asked before, but i haven't found a definitive answer. is there a way to tune the 2d physics engine to 1 pixel per unit? i'm having issues with jittering and i'd really like to stick to 1 pixel per unit for coordinates

[modest cargo]

The physics engine has no clue about pixels, they are only used for rendering

[sage girder]

but it does have a clue about scaling, no?

[modest cargo]

What do you mean by scaling? Physics work purely in floating point values

This means that to the physics engine the "pixel grid" is just a grid of abitrary size

Maybe you can snap rigidbody positions to such grid in FixedUpdate, but it might not work well

[sage girder]

but there's a difference in precision between 1 pixel per unit and 100 pixels per unit.

[sage girder]

i am not planning on using rigidbodies for physics. i'm just trying to make a simple character controller

[modest cargo]

Unity only does physics with rigidbodies, as far as I know

[sage girder]

there's still raycasts / boxcasts and overlaps

are you saying that has no affect on pixels per unit scaling?

for example i took a character controller i found and immediately had problems with jittering and falling through platforms after scaling the velocities and gravity up to match my pixel per unit scale

[modest cargo]

I think I misunderstood what you meant by pixels per unit

[sage girder]

yeah, all my assets / sprites are set to 1 pixel per unit. i prefer this because it makes positioning of objects a lot easier

[modest cargo]

In Unity one unit equals to one metre
I don't know of a way to change this really

Or to "tune" the physics in a different way
I believe this means they're optimized to work around real world object scales

[modest cargo]

If this is the problem you'll have much easier time solving the problem if you increase the PPU and simply enable grid snapping with a smaller grid

[sage girder]

i actually meant positioning objects with numbers. it's a lot easier for me to think in pixels rather than decimals

grid snapping only solves a part of the issue

[modest cargo]

Still probably easier, considering the other option might be impossible

Could try asking in #⚛️┃physics if they know more about changing the simulation scale

[finite mesa]

can someone help me with an issue im having regarding importing aseprite animations and the sprite editor?

[blazing lily]

What material should I read to learn how to properly support different window/screen sizes in my game? As it stands anything that isn't 16:9 is breaking the CameraConfiner2D

[bold remnant]

Mao by groups what are you specifically referring to?

cause im not sure what you mean by this exactly

yeah so adding sorting layers didn't fix it

since the red tilemap is still above the other in the sorting layer

for anyone else wondering my issue I am trying to solve. I am trying to figure out if its possible to emulate the effect on the right on the left. The left is my desired outcome but is using 4 tilemaps instead of the left which uses 2 and is far easier

[lethal niche]

Ah, maybe the groups only specific to the maps themselves

the ordering of the tilemaps should already have priority layering, no?

[bold remnant]

by priority you mean the "Order in Layer"?

[lethal niche]

when you create the maps and child them to a GO it's kind of like the UI

[bold remnant]

oh you mean like in the hierarchy?

[lethal niche]

Yeah

[bold remnant]

i can test if changing the order of the GOs in the heirarchy changes anything

[lethal niche]

I thought you had it working up there, or is that just something you did in paint

[bold remnant]

up where exactly?

[lethal niche]

your image lol

[bold remnant]

oh with the left and right

no so the way i got the right to work was

i had to make a tilemap for each height in the game instead

so instead of just having a floor tilemap

that handles all the floor since tilemaps can have height now with their z value of their position

so it went from 2 tilemaps

to 4 tilemaps

so id have to have a tilemap for each height in my game

also after checking

when two objects basically share all the same info on order and position

changing their order in the heirarchy doesn't do anything

[lethal niche]

looking at some older project I do have it ordered specifically in the hierarchy, and I think the layer groups are more specific to the tilemap than the scene

annnd unity crashed

[bold remnant]

very funny

love a good unity crash

gets the heart racing

[lethal niche]

and when I say sorting groups I mean the sorting layer. Sorting groups are just another abstraction for sprite sorting, im actually not sure if it applies to the tilemaps though

[bold remnant]

I see, but I am still getting the issue since i put the floor and the red layers in

but it causes the same problem

cause the red is just still listed as above the floor in that heirarchy

[lethal niche]

Ok, yeah it seems that hierarchy does affect rendering order and the sorting layer is per map. I'm pretty sure they all render at around the 2000 default transparent queue, but I guess the ordering overrides other maps with similar values.

[bold remnant]

curious why mine was updating then when i chagned it my simple test

but im curious if you think there is a solution then that doesn't require adding new tilemaps

[lethal niche]

im not too sure how you'd do it without multiple tilemaps, but there could be more to tilemaps than I remember.

that is, if sorting layers isn't what you're looking for

[sage girder]

after spending hours working on this today / tonight, i figured out the root cause of my issue.... it works a lot better when "Simulation Mode" in the physics options is set to "Update" instead of "Fixed"

[bold remnant]

they dont seem to be, but i appreciate the help regardless

[fading carbon]

Hello, I'm doing bone animation and I need to change the sprite of an already finished bone animation, how can I do this? (if this is the wrong channel for such issues, I'm sorry in advance)

[modest cargo]

Usually bone and sprite animations are two different things
What does the setup look like in your case?

Animators override component properties, for bone animations it's the transforms, and for sprite animations it's the sprite reference
If only bone transforms are overridden you should be able to change the sprite reference as needed

[fading carbon]

I need to change the sprite without changing the bone

What about my link?

[fading carbon]

And how can you easily replace it with a link?

[modest cargo]

I see, 2D rigging
With that feature I think the intended way is to use the Sprite Swap

Hi Everyone! These import settings options for sprite textures and such, is there no way to set defaults for all sprites that I import into the project?

Use the top right sliders icon to define presets for quick access

Is it possible to switch which tile palette this tilemap is using? I want to switch to a different palette that uses the same palette layout, but I want to preserve this palette as well for other tilemaps that use it

[kind geyser]

I need to rename these active tilemaps, but I don't know how to do that, or even where they are. Can somebody tell me how to do that?

I have "Tilemap_Background" and "Tilemap_Ground"

ok I'm a dumbass

these are the names of the empties they are children of

[sage girder]

is there a way to make the normal of the start and end points of an edge collider NOT left or right?
for example, my game is built using edge colliders because the platforms can be any shape. i'm implementing one way platforms but running into an issue because the normal of the edge collider start and end is left and right (90 degrees), but i also don't want the player to be able to jump through walls either.

is there a graceful way to handle this? it looks like there's "adjacent start point" which sounds like it might be helpful, but it doesn't appear to do anything

[bleak flume]

Why not use Polygon collider instead of edge collider? https://docs.unity3d.com/Manual/class-PolygonCollider2D.html... it would be much cleaner and easier to set up.

[sage girder]

would i still run into issues with platform ends having normals that point left and right?

[bleak flume]

Not what you mean but it is all connected in one shape

[sage girder]

i'm not sure that makes sense in my case. only the tops of the platforms are to be collided with

but platforms can have walls

[bleak flume]

You can also edit the physics shape in the sprite editor https://docs.unity3d.com/Manual/CustomPhysicsShape.html

I feel like using polygon is just better than edge colliders in any situation of a sprite but maybe if you have an example of what you are trying to achieve... Sounds like you might be wanting to go one way through a collider? That could be done by using then triggers and then custom logic.

[sage girder]

i'm trying to achieve something very similar to maplestory. the platforms are connected to the sprites in a way, yes, but it's only the top of the platforms and walls. that doesn't make sense for me to use a polygon collider

[bleak flume]

With a polygon collider you can have only the area of your sprite that you want for the collision.. much like the edge collider. But it's all connected. The vertices can be edited manually like an edge collider or with the physics shape you can make it more automated if you are using a tilemap.

Just only include the top of the platform and whatever else in the physics shape or edit what you want out manually

[sage girder]

how would that work with slopes?

oh nvm that's not an issue

i guess i still don't understand how that would help me because the sides would still have left and right normals

i managed a workaround anyways. i just get the edge collider that was collided with, grab the start and end points, and if the player's box collider contains either of those two points, ignore them

[modest cargo]

@sage girder this might be useful in your situation

[earnest cliff]

Hello everyone !
I am not sure which Artist Tools channel to post that in, but I have a 2D spritesheet animation workflow question.
I managed to find some nice Open Source Assets, including the spritesheet of 600 different units. I will sort through these and repackage the sprites I want in the form I want, but I plan to use 200 sprites from these.
I want to use them in a game, using spritesheets containing Idle, Movement, Attack, Hurt and Death animations.
I recently followed a tutorial to understand how to use a spritesheet to animate an entity, using the state machine or the other thingy, and I already know how to slice a spritesheet into multiple sprites, but I did these manually.
I am now looking for ways to do that procedurally, without having to slice and pick the dozens of sprites from each of the 200 spritesheets, then do the animation handlers one by one.
Is there a way to automate this process ?
(the spritesheets come with plist files, which indicate the different states of animations in the spritesheets)

[modest cargo]

I expect so

[modest cargo]

You can look up how to create sprite slice and animation assets procedurally, and figure out how the plist files convert to that
But my hunch is that unless you know precisely what from and to you need to create the conversion process, it's likely not worth it

If the sprites are in a grid, the grid slicing should make short work of them

Additionally you can multi-select sprite slice assets and drag them into the animation timeline to add them up

If you have multiple units reusing the same state machine you should look into Animator Override Controllers

[earnest cliff]

oh, I wasn't sure about that.
It will already let me reduce the time spent on the animation half, at least for the entities with identical state machines ! 🙂

[modest cargo]

There's also another workaround that could be an option
While Unity does not recognize "sprite sheets", but rather pools all sprite slices by their unique ID, classical sprite sheet animation where states are encoded by sprite sheet index / array position will not work
But that functionality can be implemented with a custom editor script that sets Sprite Renderer sprite reference from a sprite array that represents the sprite sheet

Then you make animations by changing the custom component's sprite index rather than the animator's sprite reference, and can swap the array that represents the sprite sheet at will

But I recommend that only if it seems you'd benefit from it, in case you have a lot of sprite sheets that have the exact same sprite positions relative to each other for animation sharing

[earnest cliff]

yeah, not sure that the best Idea for me, I'm a beginner in most things Unity 😄

[modest cargo]

I'd try to figure out the best workflows Unity can offer you out of the box, like the ones I mentioned about animation sharing and quick creation
They may be a bit under a rock as many seasoned users miss stuff like that
But automating the import process or creating the virtual sprite sheet component both require at least some understanding of editor scripting so those could get swampy

[light relic]

idk why the changing of the collider's shape and offset isn't working

[bold remnant]

I think I am going to try one last ditch effort to see if anyone has this knowledge on how to solve my problem.

I am working on a 2D isometric game. Since switching to Z as Y. The map looks a lot better however I have encountered a problem that so far. After 5 days of searching, and checking what feels like every crack on the internet, not a single answer has revealed itself. Hense why I am here on my last ditch effort before maybe I scrap the entire idea or something I am unsure.

The setup: In picture one you see that my game currently has 3 tilemaps. The tilemap for the floor, the movement Preview (which are the blue tiles you will see in other pictures) and the attack preview which are the red tiles.

The problem arises with the fact that since the Movement and Attack tilemaps are higher in the sort order, while they properly render above their tiles. They should be covered by tiles that are higher up. The second picture shows the problem, then hopefully the third picture shows what I am trying to produce (the third picture was produced through just hand doing in on the tilemaps). In the third picture you can see that the top 3 red tiles are being overall covered by the higher up tiles.

The main issue I have found is that because the floor tilemap is accounting for multiple heights. I have found 0 way to do this effect. I have tried what feels like every option from materials, Render Queue, Sort Order, Order in Layer, Transparency Sort Axis. Genuinely everything.

I apologize for the long post but I am just hoping some soul sees this and knows how to fix this problem I have been having that makes me feel like I am at my wits end.

[limpid warren]

what are the best softwares for making simple 2d graphics for your game? is Adobe Photoshop good?

[solemn latch]

Why are those layers higher in the sort order? That will override axis based sorting.

[bold remnant]

trying to set them all to the same sort layer and order in layer causes z fighting and its literally just random if it decides to work

[solemn latch]

Can you set it to z and y, and add a tiny offset to the overlays' position? Or add a slight offset in the shader for the overlays?

[bold remnant]

i was kind of trying that but it didn't look good

if you are willing to test it and get a decnet lookings version that would be awesome

[solemn latch]

I don't use the tilemap at all, so I'm the wrong person to be testing anything.

You could also handle sorting yourself

[modest cargo]

@bold remnant There's a dedicated page in the docs for isometric tilemap sorting iirc which I can't fetch now

Hi everyone, I'm new to unity.
I want to ask should I used Tiled Editor or use built-in Tile Map of unity for creating 2D map & level? I hear that people said i should use Tiled for more flexibility.
Thank you :3

[abstract olive]

What were the reasons people you heard say to use third party Tiled?

[modest cargo]

I think this is the one
Not a hundred percent sure it helps in your situation, but perhaps might

[bold remnant]

[uncut dragon]

Hey guys, i got a spritepack for a modular animated character. I understand how the spritesheet works, but i think unity doesn't offer all the features out of the box as i need them (e.g. flipping sprites horizontally during animations) - what's the smartest way to solve this? should i script the keyframes manually?

[lyric sail]

You can do that or cut the animation into smaller animations 🤔

Not sure myself what might be easiest but I guess just try it out, you are on the right path

Btw I wanted to ask, is there a way to make prefabs out of tilemaps

[loud mist]

Hello! Does anybody know if its possible to align handles of points whilst editing the sprite shape controller?

[merry oak]

I'm using a ruleTile that has tiles set in a TileBase

code:

var t = oreTable.GetRandomItem();
                    if (t.id == 0)
                        groundTileMap.SetTile(new Vector3Int(x, y, 0), groundTile);
                    else
                        groundTileMap.SetTile(new Vector3Int(x, y, 0), t.tile);

As you can see the auto tile rule doesn't understand there's a tile a single tile not part of its tilebase at a neighboring coordinate.

a) is there a way to have the ruleTile adjust if it finds any tile is found (aka not one part of the ruleTile rules?
b) is there a way to have some tiles in the ruleTile [let's say either in the TileBase or perhaps palette - these two terms might not be accurate] that aren't involved in the actual rule. e.g. i'm 99% sure that the following code wouldn't work but something like this:

groundTileMap.SetTile(new Vector3Int(x, y, 0), groundTile TinOreTile);

hopefully obviously I want it to look something like this instead:

the hack I had to do to accomplish this was to make another tilemap and unfortunately an ore tile is rendered on top of a full dirt tile behind it - once digging/mining of the ore tile is complete, it removes the dirt tile behind, then the ore tile.

[cedar barn]

Hello, I am very new to unity and have been trying to make a starter project with different assets from the unity store. As of right now, I am trying to make a background with assets and a tilemap, so far I made a floor but now I want to make a background, the problem is when I drag different parts of the background into the same tilemap that I used to make the floor, it looks so out of proportion. The mini blocks around the middle are suppose to be clouds but each individual block is a cloud and I do not want that. I want the clouds to look normal and big but I don't know how to do that.

[merry oak]

good afternoon Hollow King. I'll be honest, little hard to make out what icon is considered a cloud. I'm fairly certain that the icons you have listed below look like they're part of the same tileset so I'll take a moment to think that resizing your tile sheet is not the answer. Are you certain that the tiles that are blue in color aren't individual slices of a cloud which make up the top and bottom of a cloud or maybe even that these tiles don't represent a cloud but maybe a river appearance?

do you happen to have a screenshot of what perhaps a scene looks like from the asset store to provide perspective?

[cedar barn]

sorry, i took a break from trying to fix it, These are the original assets that i got from the unity asset store

u can see that some of them have different clouds

but when i dragged them into the first tile map i made

this one

you can see the differenet cloud blocks i put in, in the bottom left

When i tried to put the into the game scene, the clouds where way to small and I couldn't combine them to make a bigger cloud

this is what the original asset pack for the clouds look like

i want my background to look kinda like that

[modest cargo]

Do your tiles from different sources have the same PPU?

[cedar barn]

i have no idea what ppu is

[modest cargo]

Pixels per unit value

[cedar barn]

i dont know how to check

let me find out

i dont think they are

[modest cargo]

If you want pixels of your sprites to be the same size, they must have the same ppu

This will mean they will have a "correct" scale while keeping sprite resolutions consistent

[cedar barn]

so its not smart to mix different tiles?

[modest cargo]

Rarely

[cedar barn]

ok

i think ill stick with the second tilemap then

[modest cargo]

You tend to get different resolutions or tiles for a different grid size
And differing art styles also

[cedar barn]

how do i check what size to make each square

[modest cargo]

To know the correct PPU, count the number of pixels "one tile" is wide

[cedar barn]

i have no idea how to check lol

[modest cargo]

You could count them one by one
Or use an image editor with a marquee tool that tells you the selection dimensions (or potentially the sprite editor if that one tells you the slice size)

[cedar barn]

this is the section i am on right now, im not sure how to count the pixels from here

[modest cargo]

I'd open the texture with an image editor

You have little chance of counting it from a sprite with that much solid color, from a small preview thumbnail no less

[cedar barn]

ok

will photos on pc work?

[modest cargo]

No, not an image editor

it also filters images when zooming in so it smudges out pixel art

[cedar barn]

is there an image editor that automatically comes with windows 11

or do i have to download one

[modest cargo]

Paint, and it does tell you selection size

[cedar barn]

i got to this point here

but it seems like they all have various sizes

[modest cargo]

Doesn't look that way

Select one of those blue squares with the marquee selection tool and one of the numbers at the bottom bar reports the selection dimensions

Eyeballing it it looks like 64x64 but I can't say for sure as your screenshot appears zoomed in or out

[cedar barn]

ok

[modest cargo]

The rest of these are one grid square in size, whereas the long ramps appear to be 3x2 squares

The square size / ppu is often reported on the asset page, but often also not so this is a good skill

[cedar barn]

thank you

i think its 48x48

[modest cargo]

Seems right

[cedar barn]

and then from here what happens?

[modest cargo]

This means the sprites should have 48 PPU value in their import settings, and so will every other sprite also, if you want to keep their resolutions consistent with each other

Your sky tiles appeared small not just because of potential PPU discrepancy, but because the grass tiles you were combining with them were designed to look larger relative to grid size

The leafy details were much larger within one square compared to the grass tiles that were intended to go with the cloud tiles

[cedar barn]

ok

ill try and fix it

[modest cargo]

Now when you use the tiles from this tileset, they should all appear just like in the example

[cedar barn]

ok

let me test it out

[modest cargo]

That said it's not a hard rule to not mix different PPUs, but more of a stylistic rule that pixel art is supposed to obey
Plus it helps you keep track of how big every sprite is relative to the grid

[cedar barn]

ok

[modest cargo]

For example if you have a character sprite that's 48 by 96, you know that it's exactly one tile wide and two tiles tall (with 48 ppu)

[cedar barn]

ok

hopefully all goes well

thank you for your help g

[modest cargo]

Hopefully it's all a bit clearer

[mortal acorn]

Why isn't the shadow caster using a sprite renderer not working properly? It's acts like the transparency of the sprite is solid:

This is how it should look (I did this by using the shape editor and manually setting points):

[outer jasper]

Does anyone know how can I stretch the sprite to fill the bounding box of the object?

[modest cargo]

Change the transform scale or author the sprite in a way that it fills a square to begin with

[cedar barn]

im not sure where to find the option to change the size of the palette to fit in the boxes

[normal wasp]

how do i stop the empty pixels from getting filled in?

[pure turtle]

how can I draw a 2d map for a game? If I want to make a cave that has twists and turns, for example, tilemaps wouldn't work the best. so how can I draw a 2d map then get collisions for it?
right now i'm thinking of just drawing a map then using a polygon collider but this just doesn't seems like an elegant solution. thanks!

[cedar barn]

nvm, fixed it

[modest cargo]

You should be saving to png or tga, so alpha is preserved

After that it gets applied automatically if you're using a sprite type texture in a sprite component

(if you're using a custom shader you'll have to use the texture alpha when sampling)

[normal wasp]

deleted and readded the sprite renderer component without changing anything and somehow that fixed it, thank you

[modest cargo]

What kind of map exactly? Why are tilemaps not an option?

[cedar barn]

i finally managed to fix the tilemap sizes and implementation. Now the square goes behind the tilemap, im not sure how to make the square go infront of them instead of behind

[modest cargo]

What is the square meant to be? What do you mean by in front?
If it was behind, I assume we would not be able to see it

[cedar barn]

the square is a placeholder for the main character, you see how the top of the square is very slightly behind the blue sky, if i go higher the box goes behind it

the dark blue is literally nothing thats why you can see the box

[modest cargo]

That's important info

@cedar barn https://docs.unity3d.com/Manual/2DSorting.html
All 2D renderers utilize these sorting priorities

[cedar barn]

ok

[pure turtle]

tilemaps are more blocky if that makes sense. I want a custom drawn map that can have smooth curves

so a rock for example

I kind of want a smooth rock rather than a pixelated one

[modest cargo]

Tilemaps don't have to be blocky nor pixelated, strictly
But if you want very smooth organic curves of inconsistent sizes that never repeat then you'll probably want something drawn
You can make big sprites that use the polygon collider, in which case I guess your only worry is performance potentially

Polygons are kind of expensive colliders, so if you find them to be a performance bottleneck, you could slice your drawn map into chunks in a grid

[pure turtle]

Alright, thanks

[astral widget]

I am trying to make animations for 2d spritesheets. I am using this tileset:
https://finalbossblues.itch.io/time-elements-character-core-set

Long story short, each piece of the sprite is broken up into a tilesheet that is 23 x 4 sprites. To make a character, I have to layer the sprites together (hair, head, body, and so on).

I want to create a set of animations based on this (for example walking downwards is Sprite Index 0-1-2-1). I want to apply this to all of the sprite sheets, so that I can just build it (similar to how it would work with 3d models). Is there a wayt to do this easily? If not easily, can I automate creation of animations, so I could define this and then generate the animations for every sprite sheet?

[solemn latch]

You can just have a single animation and swap the texture using a shader, or you could make one set of animations and automate switching the textures into multiple assets. Really depends on your workflow preferences.

You could also probably automate converting the modular sheets into sprite libraries.

[modest cargo]

I think you could make a component that holds an array of sprites, and sets the sprite renderer sprite reference by the index of the array, and then you animate the index rather than the sprite reference
Then your characters can share the animation with just a swapped sprite array

[errant surge]

how do most people handle making maps in top down LDTK
i've drawn the level layout plans, then i'm trying with 4 layers and i'll use auto mapping later? is that the right way to do it or is this weird

[ashen flint]

Hi everyone
I need to add many (~1000) poly/spline shapes to my game as part of Level Design.
I tried Sprite Shape, but it "overworks" (does stuff I didn't ask it to). I want the outline in white (the one which actually follows the points I set) to be the final shape. Instead Sprite Shape extends the shape outwards, even worse - it doesn't properly "merge" sides (top right corner) depending on the angle (My Corner Threshold is already at 90 maximum). I found each vertex has a "height" attribute, which affects extension distance, but it needs to be set manually for each(!) vertex and its minimum value is 0.1 (instead of 0).
Any way to prevent extension entirely?
I don't need any edge graphics, just fill graphics.

[solemn latch]

You can have a fill without an edge on a spriteshape.

[ashen flint]

That sounds like what I need, but how?

[solemn latch]

It's been a couple of years since I have needed to, but from what I recall you just don't define an edge? Might vary with version.

[ashen flint]

I didn't, the screenshow above is pretty much its default behavior, and I couldn't find an edge-parameter so far.

[ashen flint]

I found it: you need to create Sprite Shape Profile and it has the necessary settings

Anyone knows the corresponding Sprite Shape shortcut to "Start editing the Shape in the Scene View"?

I couldn't find in Unity shortcuts window

[solemn latch]

I dunno if there is one

[abstract fjord]

hi, is there a reason for why my one way platforms aren't working? i can't jump through from the bottom

[modest cargo]

Is your character using a rigidbody? This is just a hunch but I feel that could be something

[abstract fjord]

it's okay

i figured it out

i feel rlly stupid rn

thx for replying tho

[modest cargo]

Well what did it turn out to be

[abstract fjord]

there was another layer ontop of it

i'm an idiot

[modest cargo]

One thing I've learned is that no matter how smart you become at this stuff, the dumb mistakes never fully go away
They're just another part of the troubleshooting process

[bright scaffold]

For my game I need some objects to move with other objects but they can't just be parented, so I am using AddForce(rb.velocity). Through trial and error I figured out you have to multiply the velocity by the mass and drag of the child rigidbody, but this keeps on slipping ever so slightly over time. If I increase what I multiply by for even 0.01 it starts slipping forwards, so I think I have the formula correct, and I have no idea why it's slipping backwards. Example: big ship with rigidbody2d and a barrel on it also with a rigidbody2d. Barrel has 3 linear drag and 10 mass, so I do AddForce(boatRb.velocity * 30) which means it moves for the most part with the boat but its slips backwards a tiny bit each frame. Anyone know why?

I think this is the right channel

[modest cargo]

Why can't it be parented?
In other words what's the root of the problem

How do you need them attached

[bright scaffold]

It can't be parented because both the parent and the child have rigidbodies and unity doesn't like that for some reason

So the child doesn't move with the parent

But the workaround was working mostly fine

Until I encountered this issue

[modest cargo]

Rigidbodies have indpendent physics unless one of them is set as "kinematic"
The correct way would be to use a fixed joint, I believe

[barren anvil]

In skinning editor, how can I fix things like these?

[errant surge]

how do most games go about creating shadows for 2d objects?
I understand i could draw / duplicate every sprite like this but is there a better or more common way?

[snow willow]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@17.0/manual/2DShadows.html

[errant surge]

i'd love it if it worked but it does this
looks completely different to the images in the docs

[errant surge]

grass looks seperate and from what i can guess i dont think that ground is done using tiles
probably instead is predrawn

[modest cargo]

Don't know of a "common" way
That kind of shadow techique can be automated with scripts that create shadow sprites, or potentially with the help of shaders
Shadow blending will be a challenge though
Unity's own 2D lighting can only do infinitely tall (or deep, depending on perspective) shadow casters
Assets on the store like Smart Lighting 2D and Modern 2D Shadows purport to do the kind of shadow casting you're looking for, but I have no experience of them

[solemn latch]

Better vertex positioning would mitigate that, though it may take some trial and error.

For most limbs, you will generally want joints to have a vertex at or near the actual pivot position the bone rotates around, with triangles radiating out from it.

That will minimize a lot of the 'pinching,' especially on less detailed sprites with no(say) visible kneecaps.

[solemn latch]

You can see a side by side comparison

How much of a difference one vertex can make

[coral vine]

how can I set the collisions for the tubes to none without the rule tile?

[modest cargo]

Change their physics shape in the sprite editor

[broken sable]

hey can i add like offset to tile or maybe does anyone recomend me other way to do bulidings for game?

[errant surge]

buildings are usually predrawn, not made with tilesets

[craggy salmon]

I am trying to create a new palette for my tilemap so I can drag my spliced tileset into. I watched two videos on people doing it, and they just created a new tilemap by clicking create a new palette, creating a folder and done. However when I create a new folder or select an existing one, it doesn't nothing and doesn't create a new palette, any ideas on how to fix this?

[broken sable]

no, im gonna use rule tiles but i dont really understand it well are you able to help me with it?

[errant surge]

if youre insistent on using plain tiles go ahead, theres nothing else to say just place the tiles
but its boarderline impossible not to make it look shit
every game has assets like houses as their own sprites for a reason

[broken sable]

i dont want it to be like a stardew valley bulidings

i want it something like this

how to change rule tile to change this sprite to something else

nvm

okay so now its like this do you know how now i can fix these things? sorting layer or something?

[thin venture]

Is there a way for sprite renderer to only change color on certain parts of the sprite?

[brittle terrace]

Hi, i am making a simple 2d game and i have a problem regarding particle systems. I set up a custom axis for my transparency sorting mode (x=0,y=1,z=0) in my project setting so that the objects with a lower y would render in front and it works for normal objects. But now i have created a fire particle system and it only seems to work when my objects are way higher than the particle system. I sent some images to illustrate the problem (first picture it works, second it doesn't). Anyone has a solution?

[brittle terrace]

the solution is to put a sorting group on the parent object

[wind ember]

Context: I want to make a dungeoncrawler where you go between rooms.
Problem: it works on a tilemap and there are 4 layers. when randomly creating a map i need to instance a bunch of rooms (as prefabs i assume) as child to a grid, but then it will instanciate 4 tilemaps per room. If we say i have 30 rooms, thats 90 tilemaps. thats a lot of tilemaps. is there any way to make this better where it spawns all the rooms walls on the same wall tilemap? that way it would still only be 4 tilemaps. or should i not do prefabs?

I am asuming a large amount of tilemaps affects performance.

[maiden sapphire]

unrelated but those trees are banger 💯

Theyre pretty nice, hey

[hollow solstice]

hi i need help with bone rigging

everytime i try to auto generate geometry to a leg it associates a nearby arm bone

and ignores the bone right on top of the leg

the arm bone doesnt even overlap the leg

at any point

[proper kiln]

You are ahead of me.... I am trying to get the bones to show. Something is misaligned on mine

[solemn latch]

Show your geometry? Might be a vertex placement issue. There are lots of times, though, where you just need to manually paint your weights.

[hollow solstice]

ill try to do it manually first

[tardy granite]

Hi guys, i want to start create game effect like skill fire/ice/water/... for my 2D topdown game. Where I could start and watch i can do to learn the rope fast? (Apologies for my english if they are bad)

[astral torrent]

Why is my selection appearing rotated when I try to place it? (I'm completely new to this)

[orchid tartan]

After hitting apply to changing my sprite sheet from single to multiple it reverts it back to single, I made sure I'm not in debug mode

[sullen copper]

I am currently using sorting layers on my characters, sorting groups. Etc.. they layer by pivot points. There is an issue though, when one of the characters is a child (it uses the same, although sized down version as the adult sprite) there is bugs, like the child appearing on top of a fellow adult rather than behind

I know this is because it still sorts by pivot point the exact same and with adult models in mind

I don’t see a way to effectively take into account characters of all life stages though

Is this possible to adjust where the character will sort based on its age? Like a setting via code or otherwise?

[modest cargo]

Why precisely does the size seem to affect sorting? Scale should only affect how far the pivots are from each other within a character, unless you're also scaling in Z axis which shouldn't be necessary

If you're using the sorting group component for the characters, there should only be one sort point per sorting group

[bold remnant]

potentially bizzare question. Is there any way for a ruletile to have the ability to interact with itself between z levels of a tilemap?

Like I am trying to see if there is anything unity has that lets me create conditions for things like this

[modest cargo]

You'd have to show the seams and the UV map
Do it in #🔀┃art-asset-workflow as this is the channel for 2D

[fast ledge]

oh thank you I apologize

[bold remnant]

darn seems like no one is sure. Which is unfortunate since google is not getting me anything either

[sullen copper]

here's an issue, like this wouldn't happen if it weren't for the size of one of the foxes

but it needs to be that size bc its a child

i guess maybe as a child i can make its box collider bigger?

[astral widget]

I'm having a weird issue. I am trying to use 3d models in a 2d game. Here is a screenshot:
The Red Square is a render texture on a Quad. The Material Shader is set to "Opaque".

This is what happens when I set the Surface Type to Transparent, it moves the texture behind the tile grid.

I can get the quad to render correctly (where the background is transparent with the alpha of the background of the camera that is being rendered to the texture, but I don't know why the quad gets pushed below the tilemap.

[modest cargo]

I see! When making isometric characters you want the character's combined pivot to be between its feet, both so they sort correctly regardless of their size and so that they scale correctly
You should be able to use a parent object along with the sorting group to fix the combined pivot

[sullen copper]

Combined pivot?

unfortunately their pivots are like right at their back

it just imported that way

and it seems to function as intended aside from this

[modest cargo]

You can override the pivot for scaling with a parent object, and afaik that works for the sorting group too

This is the same idea as with isometric trees
If the sorting point is at the base of the tree and the character's feet, they sort correctly regardless of the size and shape of the tree

And when you scale it, you scale it towards the base which also makes sense
You don't want the tree to start hovering when you scale it which happens if it's scaled towards its middle

[sullen copper]

how can I do that? the pivot point itself never changes unless i manually move it in sprite editor, using a parent object doesnt work

[modest cargo]

I'm pretty sure using a sorting group component makes all child sprites use the component's transform as the pivot

[sullen copper]

It does, but the issue is more so getting the smaller foxes to sort behind other foxes differently than if they were adults

But now that I think about it that would require changing the pivot of the adult, not the child one

[modest cargo]

What do you mean "differently"

If every character has their combined pivot at the feet (the isometric ground contact point) and they scale relative to it, they all sort properly regardless of size

[sullen copper]

Yeah mine are not having the pivot point at the feet, and idk how to put it there cause i thought you can only move pivot points in the sprite editor

and am i misunderstanding what isometric is?

my game is just a flat 2D game

isometric are 2d but looks like it's 3d

[modest cargo]

Not fully because simulating change in depth position with sorting by custom axis, that's a technique from isometric graphics
Were a game fully top-down or side-view there'd be no potential for this sorting issue

[modest cargo]

If you use the sorting group component, the sprites under its hierarchy will lose their pivot sorting relative to other objects outside of the sorting group, because they all use its pivot from then on out

I don't fully recall how it works but I assume the sorting group pivot is simply that GO's transform

[sullen copper]

is there anyway this could work with the object being a child

because making it a parent breaks A LOT of stuff

it's gonna require a lot of recoding

[modest cargo]

How so?

[sullen copper]

everything is based around the body

itself

all the pathfinding, collision, the animator

[modest cargo]

The sprite or the object? I'm not sure it's even possible to intrinsically connect the sprite renderer to those other systems

[sullen copper]

object

[modest cargo]

Then I'd assume all you need to do is to separate all the sprite parts into a child hierarchy
I'd duplicate the character and strip all non-sprite stuff from the duplicate, then strip all the sprite stuff from the original and parent

If you're using getcomponent a lot, you'll have to swap those to a different kind of reference, like ones with [SerializeField]

But compared to the hoops you've been jumping through I don't think that's a huge problem

A difficult part could be if you've been using the animator to also drive properties unrelated to the sprites, in which case you may need to refactor a bit more

In the future you should always separate visuals from the gameplay components hierarchically so when you need to swap one or the other it won't get messy

[pulsar sierra]

Why my camera dissapear im using 2d

[broken sable]

hey i need help with tile maps i dont really understand them and i need help how i can flip these tiles using rule tiles? tiles on right are good but on left they should be fliped but i dont have any idea how to do that i hope someone can help me

[pale nymph]

What do you mean by "disappear"... it's there. If you mean that you cannot see the camera outline, then just zoom in/out or press F to focus on the camera...

Also, make screenshots instead of taking pictures with your phone.

[astral widget]

If you click on the circle you can declare that the check should be flipped or rotated (depending on the indicator).

[solemn latch]

Opaque quads are sorted based on depth, but transparent ones aren't.

[broken sable]

No its not gonna work

[raven topaz]

Hi, i need help on how i could flip this group of sprite, like the ones in sprite renderer

[brazen silo]

Hi everyone. My problem is that sprite's position is changing when it switches to a different animation.

As you can see in the video, sprite's position changes on each animation

[modest cargo]

A common symptom of inconsistent sprite pivots, always happens if you slice the sprite with automatic slicing
Prefer mp4 or webm video formats as they can be watched without downloading

[brazen silo]

i fixed it by slicing by grid count and setting the pivot of all the animation sprites on the same x, y values on sprite editor. OBS records videos on mkv format by default, i forgot to change that. Thx for the reply

[sullen copper]

may someone explain how I may sort my trees? I've figured out how to sort most of my props, but the method I use there doesn't work for my tree tilemaps (URP Y sorting). sorting my trees individually absolutely does not work and I can't find anything online about common practice of how to do this. my trees are split up into 3 different tilemaps: trunks, trees, and leaves. I've found it is the best solution to leave trunks on individual Y sorting and trees and leaves on chunk. But then of course it produces this weird sorting issue, which granted takes a bit of manuvering to produce but would totally be noticable in average gameplay

how can i prevent this or is there no way and i just have to make the collision wider so this doesn't happen?

[cobalt zenith]

Hi peps. I heard of sprite shape renderer but is there something similar that can also give you the ability to give each side a specific texture?

Sprite shape profiles can give multiple different edges but it's limited to just specific angles.

[modest cargo]

By far the best way to sort is to have all the pivots at the base of the tree, like I was talking about earlier
But with tilemaps that's a bit more complicated
Do they necessarily have to be tilemaps?

[sullen copper]

Not really I just looked it up and apparently most people say to do trees with Tilemaps

[modest cargo]

I've never heard that one
It makes sense if you specifically want them to be made from tiles, so you could have trees made from fully modular square pieces

[sullen copper]

I mean there’s not much I can do with that.

Though wouldn’t it get extensive in some way if each tree on the map was a separate object

I mean there’s probably going to be like 200 trees on the map

[modest cargo]

Probably not terribly, but it's hard to say
If a tilemap turns out to be more optimized, you can also have a tile that's just by itself the whole tree

In Unity tiles don't have to be restricted to be within the tile square

[sullen copper]

how can I do that? In the sprite editor the grids on 32x32 and there are other objects on there such as the leaves and bushes

I guess I just have to do it separately from those or something?

[modest cargo]

Do leaves need to be separate? Sometimes they need to if you want to hide them contextually or something

But you could also do that to the whole tree if it's necessary

[sullen copper]

Yes they need to be separate to hide them contextually like if I go behind the tree

[autumn turtle]

Hey I'm running in this problem..
The redish blocks are Z Pos 0 and the blue ones are 2
But when placing them it gets messed up...

[sand solar]

You could try setting the Player object's transform x scale to a negative. The child objects should flip as well

[clever stream]
