[red gulch]

is there any way to have a sprite masked by multiple other sprites?

[upbeat edge]

yes the tilemap is useful for 2d pathfinding as well as world generation. you can get the locations of each cell in the tilemap and instantiate or activate objects / tiles depending on your needs, as well as having enemies locate objects on the tilemap and move from tile to tile toward them

[civic cypress]

Hey I am totally new and I am making this little game based of a tutorial. The tilemap never had any blue lines but all of a sudden (even though I have not changed anything) there is one between 2 chunks (I think thats what it's called)

[still tendon]

Does it only appear in play mode?

[civic cypress]

yes

[civic cypress]

this is how it looks like in scene mode

[still tendon]

https://www.youtube.com/watch?v=Wf98KrAyB2I is it something like this?

[civic cypress]

Thank you 🙂

[still tendon]

yeye ofc

If that guys solution doesnt work, I swear the easiest fix was to change the grid to something 0.001. I'd have to check my old 2d project to see lol

[civic cypress]

haha thank you, it worked though!

[still tendon]

gotcha! no problem- glad it worked :]

[severe comet]

how can I make a tilemap collider trigger for every tile, for some reason it is only triggering enter when I leave a whole bunch of tiles rather than each one

and I don't have a composite collider either

[polar niche]

send ur set up of ur tilemaps

[raw falcon]

native Pixel perfect camera (2D URP) wont work with camera stacking (what I use for parallax, especially parallax zoom) , anyone have an alternative method for PixelPerfect + upscale render texture, that would work with stacking? https://forum.unity.com/threads/pixel-perfect-or-upscaled-render-texture-with-2d-camera-stacking.948634/

[modest cargo]

I suppose you could use a custom post processing effect that upscales the render texture (though it can't snap sprite renderer position) or a parallax system that manipulates transform scales and positions instead of camera stacking

[raw falcon]

yeah I'd always done parallax that way for panning, but if you're trying to emulate zoom I find that http://www.procamera2d.com/ had a good solution in that you scale the orthosize of the cameras, and you use one camera per layer

rather than trying to "zoom" the world by scaling / translating

I'm looking into rendering to an RT at the res I want (640x360)

and rendering that on a canvas? I dunno i haven't done a lot of post/SRP style work

[raw falcon]

ok this is promising. giving me the results I'm expecting anyways

weird to have that "No camera's rendering", but I guess since I'm pretty much kicking everything onto a UI texture now

[raw falcon]

sweet, got CRT filter working too

[raw falcon]

whew, that was gonna put a damper on the day , hopefully not much of a performance hit to render one 640x360 RT on a canvas

[molten grotto]

can someone tell my why my character looks so bad

colors are mixed

and very low quality

looks fine in asesprite

its 16x32

[elfin sandal]

change sprite's compression to none and filter to point

[molten grotto]

yayy

thanks

ur best

it fixed

[elfin sandal]

np, it's a common issue that we should have in the pinned section but we don't

:/

[molten grotto]

i see

[modest cargo]

Canvas is usually not meant to be updated frequently due to performance costs, but it may depend on use case

[raw falcon]

Gotcha- if I took the stacked camera output render texture and put it on a 3D quad and pointed a camera at it, instead of putting the RT in a raw image canvas , should be the same visual but more performant?

[modest cargo]

I think so, but only testing will tell definitely
Canvas from what I know is procedural geometry and must be generated again when it changes, but I'm not sure if the updating RT texture causes that

[raw falcon]

Yeah IIRC I remember reading to build performant UIs use many canvases so that when one updates it doesn’t redraw the whole screen when you update one widget

Ok I’ll try to put the output RT on a world layer sprite or an unlit quad

My post effects should work either way

Gonna do that next year tho - happy new year @modest cargo !

[solemn latch]

Yeah. Doesn't need any special setup.

[frail glen]

So I'm trying to generate a 2d shader based on this tutorial:

https://m.youtube.com/watch?v=ACyqpLh4jrs

But even after installing URP, I'm lacking the last 4 options.

(1st picture is the tutorial image, 2nd picture is mine)

[noble cape]

I'm new to gamedev in general, I wanted an opinion, is this too big for a character?

it's for a project planning to star

[modest cargo]

That depends entirely on the game and the intended display resolution
Only you as the developer can answer that question

[frail glen]

Would love help on this because no one has responded to me on reddit

[noble cape]

dawn, makes sense, I was planning a turn based rpg, thank u anyway

[modest cargo]

Prototyping is important, as well as simple placholder art
When placing your character in the prototype project you'll pretty quickly see if say, the character appears 6 pixels tall and all the effort you put into detail is wasted

[noble cape]

thanks, as I said I'm a noob at gamedev I will make some prototypes ^^

[molten grotto]

when i imported animation for my 2d character it disappeared

how can i fix this

i noticed that animation is happening in background layer

how do i fix this

nwm i somehow fixed it

[ornate spade]

why is it that i can't slice in the sprite editor?

[modest cargo]

You can only slice "multiple" type sprites, for one

[ornate spade]

yeah i figured that out after one google search, which is probably the place i should have started with but still thanks

[leaden sonnet]

Does anyone that has a good idea of Rule Tiles think they could help me out? I want to get these tiles to create a wall like this, but i'm having trouble getting the rules for it right

[leaden sonnet]

Heres some examples of what they should look like

[cerulean vault]

idk if it's too big but it's soooo pretty

[cerulean vault]

love the style man

[noble cape]

thank u, its my 1st project, I have made many pixel arts before

[leaden sonnet]

it does look really cool

[noble cape]

thank u guys ^^

[leaden sonnet]

Anyone got an idea why this is happening? I'm getting close to the result I want

[solemn latch]

Define 'this.'

[leaden sonnet]

dw its solved

[half cliff]

Hello i wanna make some pixel game art and idk if there is any pixelart people in here but if you could help me with figuring out the size of the player sprite in this picture.

I wanna make pixelart myself and I found that pixelarchitect on Youtubes art looks very detailed and good so I wanna draw mine at the same size.

It is the player sprite I'm asking the size of

Down at the bortom it says that the entire picture is draw in 640x 360 pixels if that help but I do not know if the picture is zoomed in or not so.

I tried with my eye to count the player pixels from to pto bortom i got somewhere between 49-51 and that seems off? Usually sprites are in 8,16,32,64 right? So could this be a custom size? Plz help if you can

[charred rain]

when we speak of an 64 bit character, that doesn't necessarily mean the character is exactly 64 pixels tall.

[solemn latch]

Just eyeballing it, looks like 32x64 sprite but not using the entire size. Though there is no guarantee that the artist is actually working to a grid for the character at all.

[shadow cargo]

Forgive me if this is the wrong channel, I'm new to Unity.

I have a camera outputing to a "Render Texture". But when I try to apply that texture to something, it doesn't show up in search?

[shadow cargo]

Alright I answered it myself. I needed to apply the texture to a material, and then apply the material to the object.

[forest dagger]

Why does the sprites overlap? I used 2d sprites in designing and now when a panel appears even if it's above it, the sprites is still shown on top. How can I make it not overlap?

[willow reef]

Anybody know how to set the background image for a 2D scene? I don't understand it from googling it alone

[abstract raptor]

Hi there. I'm getting an unslightly line beneath my main character sprite during animation, even though I've packed it into a texture atlas. Can anybody suggest a solution?

This is the character sprite sheet.

Filtering is set to point, there's no compression.

Wrap mode is clamp.

Padding is set to 8 instead of the default 4.

[solemn latch]

That is the base file, not the atlas?

[abstract raptor]

That's the base file. I'm not sure how I can show you the atlas...!

There we go...

I'm also wondering how people normally do collision with 2D - do you do an entirely separate tilemap, or do you set up the collision for each sprite, or both?

[abstract raptor]

Finally, I've also ended up with some really bizarre 2D collision from the Tilemap Collider 2D...

Note the grass square to the bottom left of the bridge, just below the pink circle. This area should be walkable, yet I've ended up with a duplicate of the collision from the tile below it (a sort of lopsided trapezoid).

Can anybody suggest what to do here?

[abstract raptor]

Hmm. I seem to somehow have tiles under other tiles. Hmm.

Time to call it a night.

[modest cargo]

You'll certainly want to remove the sprite slices that don't have characters in them before creating the atlas

[bold bluff]

Performance-wise, is it detrimental to generate high-vertex custom outlines for sprites?

[solemn latch]

I mean, it will be more expensive than not doing that... but the difference will be negligible in most situations. Of course, it depends on what you consider to be 'high vertex,' too.

[bold bluff]

I assumed that, but, the documentation says that it will lead to better performance, which confounded me. In terms of quantity, I don't know exactly, I'm simply using the automatic generate function from the sprite editor, which, from what I can see, generates not that many points, but I could be wrong.

Here's the documentation in question https://docs.unity3d.com/Manual/SpriteOutlineEditor.html

[solemn latch]

Well, generally speaking, rendering a transparent pixel is more expensive than evaluating several vertices. So if you can spend a couple extra vertices to cut out a big chunk of empty space, then you will usually benefit. That generally won't be what I'd call high poly though.

[abstract raptor]

Thank you @modest cargo , will do that in future. As this is mostly a test, I guess I'll live with that for now.

Folks, if I'm looking to put pixel art on a recent iPhone screen (so something like 1179 × 2556), but also ideally put it on an average Android and later to Steam, is there a procedure I should be taking to ensure the game looks roughly the same on all displays? I'd know what to do with Unity UI, but I'm new to working with sprites here...

Supposedly the latest Pixel phone is 2400x1080 (2.22:1)

[snow ginkgo]

Hi! Can anyone explain to me why should I create the sprites in an atlas instead of invididual sprites? In the case that you want to change the atlas rows/columns I guess it will be a problem right? That wouldn't happen with invididual sprites, or am I missing something

[solemn latch]

There are many reasons to have the sprites packed into an atlas, but you can usually have unity create the atlas for you after import, and still work with individual files. You might still want to create in an atlas format for animation purposes

[snow ginkgo]

Yeah having them invididually and them create an atlas from them on Unity was my current approach but I see that a lot of people create them as an atlas directly

[solemn latch]

Well, a lot depends on your overall workflow. Building the sheet yourself also gives the most control, of course.

And of course, a lot of people use external software that exports as sprite sheets, so that's a good reason right there 😄

[solemn latch]

You can tile it, or create different versions for different resolutions.

[gusty lichen]

hmm..I'd like to have the 2D edge shading from the original box incorporated into the overlay though. Is it possible to tile it as an overlay?

[solemn latch]

Depends on how you're overlayingit

you could also just nineslice with a tiled center

[gusty lichen]

ooh that sounds like an idea! do you have a link for how to do both 9 slice and tile on the same image?

[solemn latch]

https://docs.unity3d.com/Manual/9SliceSprites.html

[modest cargo]

I'm not suggesting it just for optimization, but also to troubleshoot the problem
The sprite sheets colored background pixels should not be able to leak into the sprites when using a sprite atlas because of the margins, but it looks like it happens anyway
Without the excess sprites in the atlas at all, it would be impossible so if it still happens after removing them that means the atlas isn't being used for whatever reason

Note that you won't have to modify the sprite sheet for that, just select the sprite slices you generated in sprite editor and delete them, then recreate the atlas

[sharp hedge]

i am using a render texture with resolution 640 x 360 to get a more pixelated look, however, the color of urp/lit materials with emission appear very dull. how do i make the colors of emissive materials appear in the render texture like how it actually is in game?

[modest cargo]

Changing Color Format R16G16B16A16_SFLOAT could be a solution
The render texture needs to support HDR and to be able to store the necessary color information

Assuming that's how your project is handling high emission values

[sharp hedge]

i see, this resolved the issue. i thought itd be related to the color format, though i wasnt sure which

[gleaming perch]

Hi! Does anyone know of a tool with which I can organize the assets of a sprite based game, to make it easier for my artist to make level and interior decorations. My idea is that there would be something similar to the tile palette but with assets organized by categories and perhaps if these could already be prefabs with characteristics (colliders, scales, scripts, etc) it would be better.

[abstract raptor]

Ah, 10-4.

I've moved onto a different sprite sheet now, but that was good advice, appreciated.

[short osprey]

Hi people! Is there an API to calculate the real bounding box of a Texture2D? For example a 100x100 texture all transparent with only a 20x20 speck of color in the middle, I would like to ask Unity and have it respond to me something like (20, 20) or Vector2D {20.0f, 20.0f}

[short osprey]

Meanwhile I came up with this kind of thing...

using UnityEngine;

public class VisibleTextureRect
{
    public int x;
    public int y;
    public int width;
    public int height;

    public VisibleTextureRect(Texture2D texture)
    {
        int imageWidth = texture.width;
        Color32[] pixels = texture.GetPixels32();

        int x1 = texture.width;
        int y1 = texture.height;
        int x2 = 0;
        int y2 = 0;
        int row = 0;
        int scan = 0;

        foreach (Color32 c in pixels)
        {
            if(c.a > 0)
            {
                if (scan < x1) x1 = scan;
                if (scan > x2) x2 = scan;
                if (row < y1) y1 = row;
                if (row > y2) y2 = row;
            }

            scan++;
            if(scan == imageWidth)
            {
                scan = 0;
                row++;
            }
        }

        x = x1;
        y = y1;
        width = x2 - x1 + 1; if(width < 0) width = 0;
        height = y2 - y1 + 1; if(height < 0) height = 0;
    }
}

it seems like working, but still, if there is something built-in I would prefer to use that. I tried to google with no luck before doing this.

[thorny laurel]

is there a way to replace a 2d animation with another sprite to not have to reanimate each sprite

someone mentioned this was possible but i dont know how

or i misunderstood

[gusty lichen]

i just replace the sprite in the originally used png in photoshop or whatever and it updates automatically. Might be misunderstanding the question though.

[abstract raptor]

Is there a way to group select sprites in the Sprite Editor and change all their pivot points at once?

[modest cargo]

Not in the editor, I believe, but the .meta file that contains the pivots should be able to be modified externally in whichever way if you delve into it

[abstract raptor]

Aah. I get you. Hmm. I'll look into that.

I'm having a situation where the 2D grid doesn't seem to match up with the objects in my Tile Palette. I'm currently twisting all the dials and flipping all the switches, but if anybody knows what's going on here, I'd appreciate a pointer.

[modest cargo]

The sprites' pixels per unit value should match the intended pixel size of each tile
I would stick to one-unit grid to minimize relative scaling weirdness

[thorny laurel]

I think we might be meaning different things. I kinda mean for making new characters. I'd like to copy the animation files from the previous character and then just use new sprite sheets on the current characters animation file, but if I were to replace it like how you're saying I think it would replace all of the characters with that sprite which is not what I would like. Just the current character for new character creation I would like the sprite to be replaced

[solemn latch]

I believe the free shoebox tools on the asset store has a tool for that.

[jovial trench]

Hello, importing 2d textures onto unity and ive been trying to find how to align the grid with my textures pixels

i found out the grid size should be 512 units. But there is this small offset that seems to being present that i cant figure out how to fix

[modest cargo]

Why that much?
I would go with 1x1 grid and alter the texture pixels per unit instead

[jovial trench]

How may I do this instead?

[modest cargo]

Have you changed any pixels per unit values?

Pixel perfect camera component may help with the rendering, and to place the sprites accurately on grid in scene view I would use grid+vertex snapping or type exact values for the transform position

[merry torrent]

Hello, is it possible to add a Physics Material 2D to Only One side of a Edge Collider 2D for a Sprite Shape? as shown in the picture? I looked everywhere but couldn't find an answer

[lunar mist]

im really new to unity so this may not be a good answer but i would use more than just 1 collider

.

anyone know how to get rid of the tile pallete selector
solved

[merry torrent]

I was afraid that was the only way, I hope there is another alternative as that would require a significant amount of time considering how many unique platforms I have in the game

[uncut forge]

Using primitive colliders is usually better. For example you platform in the above picture could easily be approximated with three or even two box colliders.

[merry torrent]

I agree as that should have been done but that doesn’t fully solve the current situation as these platforms are already in a live game and I can’t change the collision as that would highly alter gameplay, speed runs times, ect…

[abstract raptor]

@solemn latch - thank you, I'll investigate these! https://assetstore.unity.com/packages/tools/sprite-management/shoebox-tools-for-unity-35760

Does anybody have any experience using the Sprite Resolver / Sprite Library asset and component? I'm having trouble getting sprite replacement for characters in a Zelda-style 2D environment working correctly. I'm following this tutorial - https://www.youtube.com/watch?v=6mNak-mQZpc - and have reached 8.55 . I can add the Sprite Resolver properties and get the correct sprites keyframing in the timeline, but if I remove my original sprites from the timeline, I can't see the character at all in the Game view. Is there anybody out there with some experience with swapping out Sprite Sheets? (I'm going to have to leave my computer for about an hour, but if anybody has experience with this please tag me and I'll get back to you very soon...!)

[wraith bay]

How can I attach a texture/shader to a sprite?
I got some shaders from the asset store and added them to my sprite renderer, but my sprites did not change at all.
what is going on

[abstract raptor]

Folks, I have a bunch of sprite sheets (about 16), all with the same grid spacing for characters. Anybody know how I can apply the same Sprite Editor slicing to a group of Sprite sheets all at the same time?

[pastel abyss]

hi folks, uber-noob here! just started this week and am having a weird issue with 2D Collision. The green boxes SHOULD represent the Tilemap Collider for the walls/door here, but instead they are reaching all the way out to this red area. My character can move just fine, but it is trapped within the red area. Nothing I am aware of indicates how/why this is the case. Any advice? TYIA!

[pastel abyss]

you could make them into one large sheet first

[abstract raptor]

Sadly, I don't think that would work with the Sprite Resolver. That seems to basically need several sheets of animated sprites in the exact same positioning.

Regards your problem, @pastel abyss , I had something similar just recently where I had multiple tiles overlaying each other on different 'heights' (see the Tile Palette). I deleted the offending tiles and replaced 'em with single non-collision tiles and it all worked out, seemingly. Not sure if that's your issue, but might be worth a shot...!

[pastel abyss]

I'm not sure what you mean by "heights"

[abstract raptor]

Yep, that was unclear, sorry. I'm referring to the Z Position, as can be found at the bottom of the Tile Palette - see here:

[pastel abyss]

I see. My Z position is locked and I have not done any sort of overlaying tiles. just really weird random collisions.

I'm baffled. Completely restarted an entire new project from scratch, ONLY the PLAYER and the WALLS have any sort of collider on them. The FLOOR is on its OWN TILEMAP (again NO COLLIDER), yet somehow my player is stuck in a 5x8 grid in the center of the floor...colliding with NOTHING. Nothing shows up under contacts. 🫠

[silver tiger]

How do i determine what the origin cell of a tilemap is in the editor?

[maiden forge]

In your tile palette inspector area did you select the right grid to place it on and not the grid that has the collider attached to it?

[pastel abyss]

yes. you can see in the image, the green boxes are the only colliders that should exist other than the player's own.

[maiden forge]

On the tilemap that is the solid objects do you have a tilemap collider?

[pastel abyss]

yes

and a composite collider as well

(the green boxes)

[maiden forge]

Can you show a video or through pictures how you're placing your ground tiles in the world?

[pastel abyss]

sure, here you can see I have the floor tilemap with only a renderer component. The walls are on a dif tilemap with Tilemap Collider 2D, Rigidbody2D and Composite Collider 2D. The palette contains all the dungeon tiles (and the player sprites).

the tiles were just hand-placed 1 by 1. for some reason, the colliders on the walls are reaching WAY farther than the boxes would indicate

[maiden forge]

In your tile palette when you place the floor did you select the correct one? Then placed it..

[pastel abyss]

yes.....

[maiden forge]

No idea then.. try removing the composite? and see if it fixes the issue..

[pastel abyss]

i have already tried that... again i restarted from scratch lol its just for some reason the colliders are HUGE.

[maiden forge]

Try editing the colliders in the sprite editor..

[pastel abyss]

i did already. the green boxes....

if its in the top result of google i have tried it lol thank you for trying tho

[maiden forge]

Maybe ask in a different channel so more people see it and see if someone else has a solution..

[pastel abyss]

that is what literally every channel says lmao i dont think this place will help with this problem

[maiden forge]

Maybe a weird unity bug.. What version you running?

[pastel abyss]

2021.3.16f1

[modest cargo]

@wraith bay .meta file contains sprite slice information in text form, so to some extent you can copy-paste settings between sprite assets

[pastel marlin]

Has anyone gotten Dragonbones to unity export to work recently?

[willow reef]

Can anyone help me put my damned tiled background BEHIND all the other sprites? I tried using sorting layers but it only goes behind the player and other game objects, not the floor or walls itself

[uncut forge]

Could it be an issue with your movement script, and not the tile map?

[pastel abyss]

possibly, but its a relatively basic 2D movement setup. I'm almost certain its an issue with the colliders

inspector shows that none of the player's colliders are in contacts with other colliders (outlined in green). Somehow the wall blocks are "larger" than they should be (red boxes). If I place only a single 16x16px wall with a box colllider 2d, it extends to cover NINE TILES... really dont get what is happening

[solemn latch]

Does your composite collider have a radius?

Is the collider of your player correct?

[short osprey]

Mmm not sure if I'm saying something plausible, but... Could it be an issue with "pixel per unit"? Like, your sprite is ppu X and the colliders somehow get scaled as per ppu Y? Maybe it's impossible, but it's the only thing I can think about when I read this

Or you have a script tampering with collider shapes and you forgot about it 😅

[pastel abyss]

this might be relevant, can you elaborate more on how to check these settings? (also the only script I am using is incredibly basic YT tutorial movement

[pastel abyss]

the composite collider does/did not have a radius set, the same issue occurs even if remove the composite component altogether and just use a custom box collider around a single tile

[abstract raptor]

Really, desperate for another set of eyes on my Sprite Resolver problem. If anybody has experience with this, or is happy to be my 'debugging duck', please let me know and I'll go over it in Discord...!

[solemn latch]

And the player character?

[solemn latch]

And other objects hit these enlarged colliders?

And if you set the box collider, can't you shrink it down?

[abstract raptor]

Fucksake. The problem wasn't with the Sprite Libraries, I just needed to ensure the Sprite Renderer on a different layer. =/

[fallow flare]

hello i have script for score and its correct but its not working and
I can't transfer to the marked location. how should i go about.

[gusty lichen]

so I'm having some sort order woes...I have a bed that i want my character to be under when he's on top of the tile, but I want him to be in front of it when he's below the tile. To make matters worse, I can't use the Transparency Sort Axis in Project Settings to solve this because I'm using another Scriptable Render Pipeline Setting.

Is there another way to get around this issue? 🙏 🙏

will I just need to change Sort Order on the fly with code or something?

[elfin sandal]

Why cant you change transparency sort axis?
If youre on urp you can still change it

[gusty lichen]

Because that would mean forgoing my pretty light LMP scriptable render pipeline. Unless there’s a way to have my LMP scriptable render pipeline as well as transparency sort axis in project settings?

[elfin sandal]

Hm idk never heard of it

Have tried getting in contact with the aseet author

If its an asset

[gusty lichen]

Hmmm I can’t remember how I got it 😦 does the Universal Render Pipeline do light sources well enough? Maybe I could just use that instead

[modest cargo]

You can, such as by changing the sprite's order in layer or its depth position
or any of the other means used to sort sprites https://docs.unity3d.com/Manual/2DSorting.html
Old games used to have the bed sprite split into two, the blanket up top rendered on top, and the blanket at the foot rendered below

[stoic island]

Did we have a tool to create png spritesheet with transparency from animation in unity ? 2 years ago we had recorder something something but it never worked properly

[gusty lichen]

So the old school method would work if the bed sprite was 2 tiles long, but it’s more like 1.5 so his head would still need to be above the sheets when in front, if that makes sense.

I may just need to get creative with sort order stuff in code. Wish me luck! 💪💪

[short osprey]

Get creative. One trick I used to solve a similar issue was like to place triggers around the bed to change the character sort order on the fly

[modest cargo]

I guess the simplest way is to change the depth position a bit based on the player's position
But that might be a problem if the custom sort axis is used in some other specific way
Dunno what you mean by "LMP" or "using another SRP setting"

[gusty lichen]

Ooh that Z order thing might work because I’m not using the transparency sort axis…I might just see if I can change the sort order when the player interacts with the bed.

[modest cargo]

Sprites always use depth axis for transparency sorting (among other methods), unless you define it as another axis in settings

[abstract raptor]

Just run into this problem. I'm using 2D BRP, an axonometric pov (think 2D Zelda) and I have a bunch of spriterenders moving behind my character in a queue. Sometimes they'll be above my character, sometimes below it (in terms of Y) - and I want to have characters that are 'higher' in Y to render behind my character. I can think of how I could code this second by second, but surely this is an issue with some fairly standard solutions, given how many axonometric games are on the market...?

[abstract raptor]

...And there was, I changed the Transparency Sort Mode to Custom and set the sort axis to 0,1,0.

[ornate spade]

hey so i made a tile specificaly for this situation but its still using the other one

are bones for 2d sprites removed?

im watching this guy make a characther and he just added bones and there doesn't seem to be any in 2021 version

[elfin sandal]

its a package you have to download

look up 2d sprite rigging unity

[solemn latch]

It is the '2d animation' package.

[still tendon]

its downloaded and unlocked, still cant find it

[solemn latch]

Your tutorial might be incredibly out of date

Have you looked at the documentation?

[still tendon]

im looking rn to find a way i understand

[still tendon]

yes the person uses 2018 version, i have 2021

[elfin sandal]

Look up tarodevs tutorial his is the best and most up to date

How can I make so that TextMeshPro also only appear in front to the mask, just like the sprite?

[coral bear]

hey guys, I am making my own Flappy bird, so I created a bird for the player, but when I imported (imported as .tga) it has small, so I change the scale but he look link this, and it's not supposed to look like this, how can I change it to look normal?

this is how its supposed to look like

Even not scaled it look like the first pic

[lean estuary]

turn off compression and filtering on the asset

[coral bear]

A could find the compression, but the filtering it's already turned off

now it worked, thanks

really appreciated

[glad nimbus]

Why I'm getting this weird lines on my tilemap? I turned off compression and filter.

It's a problem I've had to. Setting grid size to 0.999 fixes it, but that's not really a good solution

Here's a short explanation of two most common causes

[abstract raptor]

Folks, I had a 4-direction sprite sheet for a character in a top-down 3/4 view and I have it setup with a 2D Blend Tree for animation - but when I move the character(s) in the ordinal directions, I'm not triggering vertical or horizonal animations. Any ideas?

[pastel abyss]

add more motions for diagonals. if you dont have sprites specifically for diagonal facing, you could use the Horizontal movement animation instead. try it out!

[solemn latch]

Is your movement script actually feeding the values into your animator?

[still tendon]

So I created this prefab by combining multiple png files, I turn this into a sprite so I can use the Sprite Editor to add bones and stuff, but I can't add the prefab into the Sprite field in the Sprite Renderer component, anyone know how to?

[abstract raptor]

@pastel abyss - I tried adding more motions for the diagonals, but whenever the motions didn't exactly hit the diagonals, the characters would freeze their motions also. I was wondering if there was a way to increase the 'activation zones' (the blue pools) to ensure the interaction was captured or something, but it doesn't seem like that's possible in a useful way.

[pastel abyss]

try using 0.1 and -0.1 instead of whole numbers

[abstract raptor]

Yeah, absolutely - the Animator Controller parameters and visual feedback are all responding appropriately to the input, and the characters run when the ordinal directions are clearly invoked.

I've done this, but it seems to have just proportionally reset the activation zones...

Yeah, again, on test, the characters only animate sufficiently on ordinals.

[pastel abyss]

you arent utilizing anything on diagonals

also can you share your player controller script?

[abstract raptor]

Correct. So I only have four directions animated in my sheets, and I'm trying to set it up so that when moving in a diagonal, one of the four ordinal directions are triggered to cover for this, as you would have seen in old 3/4 Axonometric games in the past (eg. Chrono Trigger).

I'm happy to, but it's a horrific mess, as this is the first time I've been playing with Unity 2D in this way an I've been hacking stuff out.

My apologies in advance, this shit is embarrassing.

Just tested setting the Horizontal values to .1, but that seems to be having the same issues.

[still tendon]

is there any alternatives to photoshop to create psb files for sprites?

could i use gimp?

[abstract raptor]

I believe so.

Hmm. Let me check that, actually.

[pastel abyss]

do you specifically need a .psb file or just a tool to make sprites?

[abstract raptor]

Yep, seems like, though you'll need to test in Unity to see how effective it is.

[still tendon]

basically im trying to make a character but to add bones, i have to use the skinning editor which means my gameobject has to be a sprite

what i did was i had a bunch of png's and combined them to make a gameobject

but i cant use the sprite editor because on the inspector, spire renderer, the sprite field is empty, i cant assign my game object as a whole (i tried putting in just the png of the torso thats why it says body there)

but then sprite editor only opens the torso part

every tutorial online makes a psb file and edits the sprites like that so idk what to do

[solemn latch]

Yes, with caveats. Most software that can create a PSD(with converter) or PSB file doesn't actually provide the metadata Unity is looking for, so while it will usually work you can have subtle problems later- especially if you try to edit your existing PSB file.

[pastel abyss]

right on. .psb is an extension for photoshop files. you dont need that specifically

[still tendon]

what can i do in my scenario then

how can i add bones to my gameobject up there

i cant add the gam object "character" into the sprite field or the prefab or the object

[pastel abyss]

you need to find the prefab image in your assets and drag that onto the sprite renderer? i think?

[still tendon]

yeah doesnt work tho

when the drag it onto the field it just goes gray doesnt allow me to put it in

[abstract raptor]

Still really stumped with this ordinal sprite nonsense.

[still tendon]

what do you mean?

[solemn latch]

I would set specific values rather than feeding in the input, definitely

2d sprites don't 'blend' the way 3d transforms do

[maiden forge]

The easy fix is putting the tileset into a sprite atlas.

I done this and never had the issue again.

[abstract elm]

whenever i inport a tile for my tilemap it gets a white outline like this

how do i fix it? i am importing pst files from photoshop

[abstract raptor]

Forgot to say, @solemn latch , your advice fixed the issue. Of course Blend trees are dumb for this...!

[solemn latch]

Use a transparent shader

[maiden forge]

Create a blend tree for the idle facing directions...

[abstract raptor]

Oh, sure. Hey, that's vestigial from the previous version... and it ain't hurtin' noone (yet).

? Sorry, so that piece of code sets the parameters if there's any input. I'm not sure about the relevance?

[maiden forge]

Nevermind, haha.

[abstract raptor]

Was I missing something?

[full breach]

i dont know if this is the right spot to post this but is there any way to make the sprite fit the shape more? (its 3 seperate blocks)

[solemn latch]

Those handles are just the rect transform controls; it should adapt to a multiselection

[ruby hinge]

i have trees. the player. the backpack.

sorting layers dont seem to work the way i would have though

if i put the player and his backpack on the same sorting layer. and the trees seperate. it still changes the trees?

I want the backpack to be behind the player

but when i set that up. all the trees are always behind the player regardless of position :/

[uncut forge]

Pixels per unit in import settings I think is what you want.

[elfin sandal]

so when renaming a psd file to psd, do the layer IDs not transfer over?

when i'm in the skinning editor in unity i cant seem to be able to organize the sprites based on layer folders and such

anyone know a work around?

actually is there an asset that just does sprite rigging better than unity?

nvm
im an idiot

I didn't realize i had to click on sprite tab

[spiral solar]

There are two callbacks from Tilemap class. One of those does what you want

[spiral bear]

@spiral solar No not really XD

[spiral solar]

I use it that way. I’m not at my desk but one of the two callbacks returns “synctiles” which return position and tile instance iirc. If instance is null then the position is where are deletion occurs. It’s in a free asset and works fine. Maybe you’re trying to do something else?

https://docs.unity3d.com/2022.1/Documentation/ScriptReference/Tilemaps.Tilemap-tilemapTileChanged.html

although this one (TilemapOntilemapPositionsChanged) can be easier to use. Both work at Runtime in 2022.1 and later. Earlier versions are editor-only https://docs.unity3d.com/2022.1/Documentation/ScriptReference/Tilemaps.Tilemap-tilemapPositionsChanged.html

[solemn latch]

Use sorting layer groups

https://docs.unity3d.com/Manual/class-SortingGroup.html

[ruby hinge]

sorting layer groups isnt working ):

it just treats everything like its in the same layer group

the engine seems to only care abut Order in Layer

does not change at all when using Sorting Layer

[modest cargo]

Order in layer is the order within a sorting layer

[ruby hinge]

doesnt work

it just doesnt behave the way it should

[modest cargo]

It does work as explained here
https://docs.unity3d.com/Manual/2DSorting.html
Sorting layers take higher priority than distance to camera
Sorting group component allows you to override that within a hierarchy by inheriting the parent's sort order relative to other gameobjects

[ruby hinge]

i think the reasons im having problems is because im making a 3d game with 2d sprites

and it still didnt work. but i found another fix

it was caused by URP messing with the layers

The sorting group component didnt work until i changed settings in the URP renderer

[unreal ferry]

[modest cargo]

You can have two separate gameobjects with their own tilemap component

Or more

[elfin sandal]

when making a 2d skeletal rig that holds various different weapons, would putting all weapon sprites in the pbs file that has character sprites be the right way, or would it be better to have weapons be a game object that's a child of the hands. and the weapons object will have a sprite resolver

or is there no right way

for what its worth im planning on implementing various weapon types with each having their own swappable palletes

[tidal turret]

If I'm packing together my sprites in sprite atlases (4096x4096), does it matter if the original texture sprites are random, various resolutions, for example npot?

because Unity is basically only loading in the sprite atlas into the game yeah? So it's pretty much "leaving" the raw texture files behind.

[orchid oyster]

I'm pretty sure this is easy and/or there's a video that easily explains this. I just don't know what to look up. I want to put a sprite ontop of another and have it slowly fade in/out of the one it is against in the same animation. Does anyone know what that is or what I should google?

[misty ore]

In the sprite editor you set the pixel size you want..

[rich gyro]

Hello, i am trying to get the height and width of a texture2D but unity always limits the texture to 2048x1024 although I changed the MaxSize in the settings of the Texture to 4096. Does anyone know why?

[rich gyro]

I wanna get the real resolution of the texture

[modest cargo]

Pixels Per Unit value in texture import settings is not matching your sprite resolution

[modest cargo]

The "Non-Power of 2" setting will still resize the texture if its dimensions aren't a power of two

[modest cargo]

Sliced sprites are often NPOT anyways so safe to assume it doesn't matter

[modest cargo]

Maybe have them under one animator which controls the alpha
Hard to say without knowing what it's for

the tiles are all the same but you can see the ones over to the right have the outlines more prominent

[graceful sand]

nvm ended up using pixel perfect camera and some other compromise

[elfin sandal]

omg so when using 2d animation rigging, if you try to have a child of a sprite it wont get moved

and you can't change the sprite to something that isn't part of the psb file

what an awful system

and if you sprite swap a skinned sprite it won't transform based on the root bone

however if you sprite swap with a sprite from a completely unrelated skeleton it will work just because the sprite is associated with a bone

awful awful

[solemn latch]

@elfin sandal yeah. All problems I've complained about =p

[elfin sandal]

more people should complain lol maybe they'll listen someday

but i found if i just go to skinning editor on a random sprite and place a bone on it then replacing sprites will work

so dumb that it has to be done that way

should just be able to use the pivot

It is obnoxious, but it feels like whoever did the sprite swapping never tried using it with a real project

[normal plume]

Hi, I'm using a 2D Texture sprite on a quad on the top face of a cube in a 3D game with URP. I have the quad's material set to transparent (this works) and I want to "paint" on the texture using SetPixel(r, g, b, a) in such a way that the paint is not transparent.

When I try to set per-pixel transparency (that is, a=1) in this way it has no effect at all, although the r,g,b values are adopted, and the alpha channel of the pixels is unaffected. Here's a picture of a test scene - the cube stripes should not be visible through the paint but they somehow are, although the (r,g,b) value of the paint is applied and obliterates the Unity logo on the right.

Here's my core splat function on the paintbrush. Can anyone see what I'm doing wrong?

    private void RayCastSplat()
    {
        var rayStart = _splatRay.transform.position;
        var rayDirection = _splatRay.transform.forward;
        float rayLength = 1f;

        RaycastHit hit;
        if (!Physics.Raycast(rayStart, rayDirection, out hit, rayLength))
            return;

        Renderer rend = hit.transform.GetComponent<Renderer>();
        MeshCollider meshCollider = hit.collider as MeshCollider;

        if (rend == null
            || rend.sharedMaterial == null 
            || rend.material.mainTexture == null
            || meshCollider == null)
            return;

        // texture has been cloned in Start to avoid messing up original
        Texture2D tex = rend.material.mainTexture as Texture2D;
        Vector2 pixelUV = hit.textureCoord;

        var px = (int) (pixelUV.x * tex.width);
        var py = (int) (pixelUV.y * tex.height);

        // hopefully the compiler unwraps these loops (how to verify?)
        var padding = 2;
        for (int i = -padding; i <= padding; i++)
            for (int j = -padding; j <= padding; j++)
                tex.SetPixel(px + i, py + j, _color);
        
        tex.Apply();        
    }

[still tendon]

can someone explain why my texture does that ?

there a bit of overlap with the side texture

[civic knot]

Is the material albedo alpha set to 1?

[normal plume]

I think in 2021.3.14 the Albedo is called the Base Map; for the transparent Unity quad on the right, the Base Map is set up like this - the base colour is white, with alpha=0.5

I want the material to be semi-transparent but then I want to locally vary the actual alpha

[civic knot]

Okay, the texture color does not override this value. It's multiplied by it, so you'll never get an opaque color with the base map color not being 1.

[normal plume]

ah wow, ok, need to experiment some more with that, thanks

[civic knot]

What you could do is edit your texture to be half transparent instead of changing the base map color. Then when you paint, your alpha would be the actual alpha.

[normal plume]

interesting, thanks, haven't tried that - don't know how to do that actually but will find out. The texture is just a screen grab in windows (I think it was saved as a PNG file)

[civic knot]

Png can store alpha values, so open it in any decent image editor and tweak the alpha.

[normal plume]

I'm still concerned that this is what I'm doing already when I call .SetPixel on the texture. I understand that multiplying the alpha will clamp my observed alpha, so when I use a material with alpha 0.5 maybe I can't go outside a=[0,0.5] range but still would have expected the SetPixel call to do something ... I tried different values from 0 to 1 ... but anyway thanks for the input, will test.

[civic knot]

So you say, setting different alpha values for _color doesn't change anything?

Does it not become completely transparent at 0?

[normal plume]

correct, even zero, testing it now - I'd have thought with zero I'd make the pixels transparent

[civic knot]

Hmm

Can you take a screenshot of the texture import setting?

[civic knot]

Okay. The settings seem to be fine. How do you set the _color value?

Although, do try disabling the mipmaps and see if it changes anything.

[normal plume]

serialized in the inspector, so I can play with the alpha (testing mipmaps now)

[normal plume]

disabling mipmaps didn't seem to help

[civic knot]

Hmm

[normal plume]

that's basically the same but with three paintbrushes all alpha=0.0 but color r,g,b

I wonder if this is some URP devilry

[civic knot]

Well, I'm out of clues. If you want I could look at the project when I have some time. If so, upload it to GitHub or something and share the link.

[normal plume]

thanks that's a very kind offer, let me see if I can figure it out but thankyou for your input

[hollow crown]

What's the material used for the overlay, and what's the (presumably a) render texture setup look like

[hollow crown]

https://help.vertx.xyz/graphics/textures/wrap-mode-clamp

[still tendon]

dosen't work

[hollow crown]

Then presumably the problem is the padding you have set up in your sprite

[still tendon]

i'm quite new so what's that ?

[hollow crown]

https://docs.unity3d.com/Manual/SpriteEditor.html the way you have presumably sliced your sprite.
If that's not it, you'll have to provide some more context about your setup

[normal plume]

I went into a bit more detail up here:
#🖼️┃2d-tools message
but it's not a render texture; there's a 2D Texture applied to a material on a quad, which sits on top of the cube (the only purpose of the striped cube is to have something distinctive behind the quad so I can see variations in the alpha). The material on the quad is a 50% transparent Default type 2D texture; here are my complete settings and I haven't changed the code from what I posted above. So the puzzle is: if transparency is working for this setup, why can't I vary the per-pixel transparency of the texture using SetPixel(r,g,b,a)? Even setting a=0 seems to have no effect. But (r,g,b) does have an effect, that's how the paint is applied.

Basically if it was doing what I'd expect, at a=1 you would obscure the stripes on the cube in the background. and at a=0 you'd hide the Unity logo (by making it transparent) where you painted.

[hollow crown]

You have a lot going on and none of it is very clear to me which layer it's applying to.
Issues:

• Transparent is generally not good for anything other than glass. Often you want Fade instead.
• The color field next to the texture will multiply with the color values, including alpha, so if your other material also has that, it won't obsure anything.
• If the quad and the cube are both transparent, sorting will occur by the center of the objects, not via their actual depth. So it's likely at certain angles the cube renders above the quad.
• If you want to render something as 100% transparent and 100% opaque, use a cutout material (the material should be marked as opaque, and then it will sort properly)

[normal plume]

OK, thanks for the suggestions...

• I only see Transparent & Opaque as options for this material
• The cube is opaque, I want to be able to vary the per-pixel opacity of the quad on top (with the Unity logo) which is 0.01 above the cube's top.
• a cutout material may be exactly what I want and I will look into that, thank you

[hollow crown]

Ah, it's Unlit. Transparent is fine, Cutout is ideal
If the above material is what you're using for the quad, then the issue is that you have 0.5 alpha, which is multiplied with your rgba values

[normal plume]

again though, wouldn't you expect that if I apply a _colour value of (r,g,b,0) i.e. zero alpha, using SetPixel, that pixel should become transparent? Just an example

[hollow crown]

Yeah. I imagine the issue is that your original texture is imported as RGB8, as you can see in the preview window. If your original texture had transparency, that channel would probably exist, but seeing as it doesn't it's been stripped to save space

[normal plume]

Ah now we might be getting somewhere - that might be the issue, or almost... I added an alpha channel using GIMP but that didn't quite work yet, I still can't adjust the alpha using SetPixel. Unfortunately I have to stop for the night but I have learned some stuff... I'm optimistic that I will fix this. Thanks for the discussion @hollow crown

[hollow crown]

• Just also make sure you've actually debugged the color value you're sending just to be sure something isn't totally borked

Sprite sheets should be authored with padding and sliced with padding to prevent this issue

Generating a texture atlas has the option to generate padding as well, to avoid the effort of modifying the sprite sheets manually

[normal plume]

[solemn latch]

In your script, the color you are drawing.

https://docs.unity3d.com/ScriptReference/Color32.html versus https://docs.unity3d.com/ScriptReference/Color.html

They can be implicitly converted between but are very different.

For instance, an alpha of one would be solid for one and almost invisible in the other.

[willow reef]

Hello everyone, I know I may sound like an absolute douche for asking this but I really need help on my new character design and I would appreciate if someone made 3 more textures for my character

My character is unfortunately 256x256 which is why it may be a pain

If anyone can help I would I appreciate it

If it's too much I will back down and do it myself as I know it is my model

Thanks :)

Oohh

That clarifies everything

Nevermind then

[analog widget]

Is there a way to make objects hide behind shadows?

Also how can I make a shadow shape out of a tilemap collider?

How to get Motion Blur working with Post Processing on 2D Sprites moving and a static camera? Builtin, Post Processing v2

[celest tree]

With the unity tilemap is it possible to just fill tiles with a solid color instead of using a spite image?

And have it fill the whole tile, even if you resize the grid

[elfin sandal]

no

[elfin sandal]

when I try to getcategory() from sprite resolver it's returning null
actually my resolver's category is getting set to none as soon as the scene starts for some reason

but even if i set the category myself it gets reset

well, I can get the category at start and save it to a string
dumb as fuck that it has to be done this way

[wet spruce]

why when i export my pixel art it changes color and how to prevent that?

[uncut forge]

In import settings, choose point filter and set compression to none

[wet spruce]

ohh i forgot about the compression, thanks

[upbeat edge]

Anyone know how I can change the offset of my tiles to give the illusion of animation here? Or if this is even possible? The water tile is perfectly tiled, so I figured this might be easier than actually doing it pixel by pixel.

[solemn latch]

That's something you'd do in the shader usually.

[upbeat edge]

I suppose it was about time I got my feet wet with shaders

[spiral solar]

Another way to do it is to modify the transform.position (or transform.scale) of a tile. This changes the position (or size) of the sprite. But you'd have to do this for each tile position - or - you could have a custom tile class that wobbles the position (or size). But a shader is probably more efficient if it's a large number of tiles.

[thorny laurel]

Hello I tried to make some tile pallets but for some reason when I paste in my sliced sprites the tile pallet shift everything on a diagonal

this happened a few times

idk what ive done wrong

[thorny laurel]

another example

i dont understand

may i crosspost this to main

[maiden forge]

Did you get this problem fixed?

Also what version of Unity you have running? Because I think this issue was fixed in Unity Verison 2020.1

There was a whole forum post about it here: https://forum.unity.com/threads/solved-weird-positioning-of-tiles-in-tile-pallette.508296/

[thorny laurel]

using this version

and no I have not gotten it fixed but I will check this out

thank you

[maiden forge]

You're welcome and good luck.

[spring isle]

how do i keep the background on the camera?

[thorny laurel]

thank you i think it worked!

there was a fix in there

[maiden forge]

Make the background a child of the camera in the hierarchy is the easiest method. otherwise you have to do code.

[spring isle]

wow that is so easy. Thank you so much!

[thorny laurel]

should creating a sprite pallet literally take one second per split sprite

[maiden forge]

I think this is based on your system and the size of the sprite.. But I could be wrong.

[thorny laurel]

i have a good system

and its of course a large sprite

i have a ryzen 9

[maiden forge]

Could be Unity bro, not 100% sure so I cannot really say for sure.

[celest tree]

I have a hexagon tilemap; what equation could I use to get all the surrounding tiles at N distance?
Currently I have this function to get the adjacent tiles; but I need to be able to also get them for any given distance (not just distance = 1)

public static Vector2Int[] SurroundingTiles(Vector2Int tile, int distance = 1)
        {
            if (tile.y % 2 == 0)
            {
                return new Vector2Int[]
                {
                    new(tile.x - 1, tile.y),
                    new(tile.x + 1, tile.y),
                    new(tile.x - 1, tile.y - 1),
                    new(tile.x, tile.y - 1),
                    new(tile.x - 1, tile.y + 1),
                    new(tile.x, tile.y + 1),
                };
            }
            else
            {
                return new Vector2Int[]
                {
                    new(tile.x - 1, tile.y),
                    new(tile.x + 1, tile.y),
                    new(tile.x + 1, tile.y - 1),
                    new(tile.x, tile.y - 1),
                    new(tile.x + 1, tile.y + 1),
                    new(tile.x, tile.y + 1),
                };
            }
        }

There must be some mathematical way to do it, other than just doing function like this in multiple iterations.

[craggy kite]

lets continue here 😄

@willow reef make thread so its a bit organised

[willow reef]

sure

Sprite Render issue

[willow reef]

I did..

you there?

[green jewel]

Hello, I am testing the tile rule and I was wondering if it is possible to make two different types of tile rule interact as in my example image, with one side of stone and the other of earth (I wish they would stick).

I hope to be in the right place to ask ^^

[sweet trench]

I dragged in a sprite that wasn't the size of 1 cell and all my cells resized, how do I fix this?

ps this is the tile palette

[tender breach]

Hi.
Can I crop sprite with mesh type full rect and sprite mode single and get new center?

[maiden forge]

Having the same issue.... LOL

[woeful seal]

change pixels per unit measure in the import settings of the image

[sweet trench]

I did, it's just that the ones I tried to drag in were larger than 1 cell yet still got shoved into 1 cell

[maiden forge]

What do all use for 2D sprite drawing?

Or just 2D drawing in particular..

[celest arrow]

Does anyone know of a way to take a sprite sheet png and automatically split it into separate png files. Not by tile size like slicing, but it cuts out the individual sprites? I have a large sprite sheet that is component based and doing it by hand is taking forever.

All of the individual sprites are different sizes.

Edit: In case anyone else is in need of this someone pointed me to https://github.com/ForkandBeard/Alferd-Spritesheet-Unpacker/releases
Works great so far on every sheet I've tested.

[polar sinew]

If you're looking for something free this website is dope https://www.pixilart.com/draw if you have an extra 16 bucks somewhere I would recommend to buy Aseprite

[polar sinew]

Scratch the website is would just download Krita

[uncut forge]

Personally, GIMP. Probably not the best tool, but it's what I use.

[maiden forge]

Thanks everyone! 😄

[thorny laurel]

import times should not be 8 hours lmao

idk what's wrong

or how to fix it

[maiden forge]

Ye, something is definitely wrong.. Maybe ask in #💻┃unity-talk or one of the coding channels were more people look at the chat and see if you can get help..

[thorny laurel]

I’ve tried to like 3 times now :(

Idk

[maiden forge]

Did you use google to see if you could anything online?

https://forum.unity.com/threads/unitys-long-loading-importing.600115/ @thorny laurel

Seems to be decent info on this forum post

[acoustic nacelle]

i like aseprite but its commercial software

[thorny laurel]

Okay I will try this thank you

[thorny laurel]

sadly did not help

alright my idea i said in the unitytalk chat worked i think

i just remove all other pallets while importing

How

[modest cargo]

What puzzles you?

[uncut forge]

That's what I was about to ask

[exotic vessel]

would anyone have tips or advice how to draw an attack animation while also incorporating it into movement? i just cant figure out if i should draw a walk, walk-attack, and attack animations or just an attack animation, any help would be nice :]

[modest cargo]

This depends on subject and intended style
If "attack" means shooting a gun, you usually would have just a variant of movement states with a pointed gun
If it's a quick swing of a melee weapon, it could have leg movements that are brief and dynamic enough to work both for moving and standing

[exotic vessel]

oh ok, thank you

[modest cargo]

You could describe in more detail how attacking works in your situation, but either way your best bet is looking at how other games with similar styles do it

[exotic vessel]

i also asked help in another server and with your answer and theirs i think i have a grasp of how to do it, thank you

[modest cargo]

Another trick is to separate the upper and lower body animations to be able to re-use a lot of actions, even if they might look a bit stiff that way

Most games I can think of with long winded melee sequences don't allow the player to move during them

[kind yacht]

Idk where to put this, but is there a way to make a model invisible and only the texture? Making some sort of 2.5D

[wind socket]

hello there friends! I've a question about pixel perfect game development. I was beaten by that last time I tried and focused on oher parts of game. However I do not want to delay this problem anymore - I've setup pixel perfect camera that is scrolling upwards constantly.

However, this makes weird jitter every several frames and I cannot figure out how to deal with this. Was looking for solutions on google, but could not find anything.

I've included movie how it looks like.

I have tried putting camera movement into lateupdate but it doesnt help. I could probably store camera position in separate field and round transform Y position to nearest 1/16 value (to match PPU) but I'm sure there must be a better, more correct way to do it.

[elfin sandal]

you mean the jitter in the UI?

if I remember correctly the way I fixed it was by downloading a UI extension

forgot what it was called tho

[elfin sandal]

does anyone know how to properly do a rule for diagonal tiles?

i want the top one to look like the bottom one

[modest cargo]

Diagonals and outer corners are interchangeable, you can't differentiate them with just tiling rules
The rules for the diagonal there seem incomplete, even if you think of it as an outer corner piece

[elfin sandal]

should I use this?
https://docs.unity3d.com/Packages/com.unity.2d.tilemap.extras@4.0/manual/CustomRulesForRuleTile.html

[elfin sandal]

crazy how I can't find anything about this when I look it up

[solemn latch]

You can always just manually place a tile too.

[elfin sandal]

yeah, but if I wanted really long levels it'd take a long while

they always say dont reinvent the wheel
but apparently the wheel hasn't been invented for this problem

[uncut forge]

That's how you can become famous

[modest cargo]

Seems useful here
I know tilemapping techniques in general, but not Unity's systems so I can't give exact answers

[solemn latch]

It doesn't look like you've correctly filled in your rules

[elfin sandal]

Its not the only combination i tried

[solemn latch]

I mean, this seems like an obvious omission

The way you have it set up, the first rule will always have priority.

[elfin sandal]

ok that works

i didn't know that their positions meant priority

[still tendon]

any idea

why this happens

?

[solemn latch]

Because you hit enter way too often?

[still tendon]

what do you mean?

[still tendon]

To be clear, is it a unity problem or aseprite?

[solemn latch]

I mean you used three lines and still managed not to say what you need help with?

[still tendon]

Oh i thought it was sort of obvious. I exported the sprites on the Right, and when i drag them to unity they get

quite distorted

i was hoping to understand the reason.

[solemn latch]

I'm on mobile so they look identical to me. Probably your compression settings in unity.

[still tendon]

where can i change them

[solemn latch]

Your compression settings in unity.

[elfin sandal]

When yu inspect the sprite

[timid bluff]

Does anyone know what the best way to implement hazard tiles (like spikes) would be? In my previous project, I just put spikes on a separate tilemap and checked for collision with that but I'm wondering if there is a better solution?

[timid bluff]

I was thinking of using scriptable tiles though I'm not exactly sure how I'd implement it.

Okay, I decided on using a GameObject brush to get the advantages of grid snapping without having to deal with tile-related shenanigans.

[elfin sandal]

i would make it so whenever the player collides with the tilemap collider it checks what tile is at that position and if the tile name is spikes then damage the player

[timid bluff]

There was some other stuff that I wanted to do that may not have been possible with a tile anyways so that's why I switched

[elfin sandal]

👍

[still tendon]

any tools to edit batches of images? I just want to change basic image properties like saturation, brightness and contrast and maybe vignette if possible?

[still tendon]

nvm I downloaded an extension for gimp that does it^^

[uncut forge]

how is it, and what is the extension?

[still tendon]

https://www.youtube.com/watch?v=K_GexKOdXmg&t=187s
This, though I havent really used it yet

[compact jetty]

How do i get the actual camera view to align with the pixel perfect green box?

[solemn latch]

Use a pixel perfect camera the same size as the box and put it in the same position?

[kind yacht]

for a tilebased game, how would I make a grid?

[uncut forge]

grid component?

[kind yacht]

but like what would I add the component to?

[solemn latch]

A game object

[kind yacht]

how would I make other objects move and scale by that grid?

[elfin sandal]

easily googleable

[little kindle]

I don't know if this is the right channel (I'm assuming it is), but you can see in the first picture there's a little sword that is to the right of the big sword. I did not put that there and it's not in the hierarchy, but it does have the same sprite as this prefab (second picture).

does anyone know why that little sword here

he's just standing there menacingly

also I can't click on it in the scene

I saved the project, restarted unity, and now it's gone

that was strange. If anyone does find an answer though it would be nice, cuz I am curious how the heck it got there

[loud grotto]

Hello, how can i give an npc a decided path to follow?
I need to give an npc a specific path to follow, which includes jumping and falling. I would need it not to follow the player, but to go direct. I was thinking about NAVMESH, but it follows the player. Advice?

[solemn latch]

Really an #🤖┃ai-navigation question but you can use pretty much any method, and just periodically update the goal position.

[polar basin]

My slicing goes on very imprecisely, why is that? Here's like a 13x13 selection but you can see that there's only a little chunk in the left and a too big one on the right

[still tendon]

I really didn't think it'd be this difficult but how does one create their own custom tiles? I got an asset package from the asset store but it's missing a regular black tile and I'd like to make it myself. What I've found online is for either scripted tiles or rule tiles

[polar basin]

???? drag and drop the sprite onto a tile palette

[still tendon]

My question should have been how to make a custom sprite then

[polar basin]

What do you mean by custom sprite? It will have a custom texture

[still tendon]

That's my tile palette

However I want a tile that's all black (same black those tiles)

And I can't figure out how to create one

[polar basin]

Well

Get a black sprite

And do what I said

[still tendon]

Got it

[loud grotto]

And how can i do that?

[solemn latch]

You ask in the correct channel.

[radiant grail]

Does anybody know any good online softwares that are very good for creating 2d sprites?

[solemn latch]

I'm sorry, nobody does.

[ember lark]

light2d, why's the yellow line flat? it's usually a full circle

[thorn star]

not certain where to put this, but i feel it belongs here? I have discovered an odd quirk with the orthographic camera, it is that if an object has a higher y than the ones surrounding it, it gets given a black outline by some imperfection somewhere... Is there a workaround?

[lean estuary]

If alignment is slightly off or imperfect pixel per unit setting might allow bleed in from the border. Hard to say. Pixel perfect camera usually fixes looking through seams thing. But I've had it work without it with tilemaps as well.

[thorn star]

ok thanks, i will look into that stuff then!

[lean estuary]

One workaround to fix it is to make tile slightly larger to cover bleed in. But ideally you could match it perfectly.

[thorn star]

ooh, ill keep that in mind, thanks

[thorn star]

ok pixel perfect camera did not fix it, but i cannot guarantee that i set it up properly

[thorn star]

im probably going to have to do this, 1 or 2 pixels shouldn't be that noticeable hopefully

[lean estuary]

does the tile have any compression or antialiasing on the asset?

[thorn star]

i dont think so, but the texture is 3 times the size of the other textures, with the tile being 3 times scaled on the x and z to give it the illusion of being a tall tree.. could that be the cause?

[lean estuary]

That looks like something under the tree bleeds in though not the tree itself

[thorn star]

there isnt anything underneath the tree, with my current setup i can only have 1 tile per place

[lean estuary]

And that's a game view and you don't have any gizmos enabled?

[thorn star]

as far as im aware

[lean estuary]

It frames exactly the tile under it

[thorn star]

yep

[lean estuary]

don't seem to be related to the tree

[thorn star]

the black border thingy is exactly where the transparency in the tree starts, hence why i would think it was the tree...

[lean estuary]

Yea, that looks like an asset artifact. Cleanup edges.

[thorn star]

how would i cleanup the edges?

[lean estuary]

make sure you don't have semitransparent anything around it. You can see the top part of it is just fine

[thorn star]

none of my sprites have anything semitransparent as far as i know, I'm quite a noob to drawing pixelated sprites so i've been sticking to either 100% or 0% opacity for all pixels

[lean estuary]

Right, you are scaling it and it is mismatched, the thing is not pixel perfect anyway, so make it larger to cover seams

[thorn star]

ok, thanks so much!

[lean estuary]

you could also have background of the same color so it would help hiding it

[thorn star]

ooh, like using a solid colour sky box?

[lean estuary]

Yes. Also you could have a second tile grid to separate tiles from trees, you'll have more freedom with their positioning

[thorn star]

fascinating, ill keep that in mind, as that sounds cool, thanks a ton!

[lean estuary]

because you will have problem drawing object on that tile, they can't be sorted like this

that is if you want for something to appear in-front or behind the tree while standing anywhere near it

[thorn star]

not quite certain what you mean there, but currently i use y to get things to render over or under eachother, which seems decent atleast for now lol

[lean estuary]

if you have a floor attached to a tree, you can't exactly draw something behind it, the floor will be drawn on top of it if you do

[thorn star]

my tiles are all individual currently, they cannot be attached to eachother, but should that ever change ill keep that in mind

[celest tree]

I'm currently trying to learn the 2D Sprite rigging. I have a question if you have a .PSB where you want multiple variations of a layer. (For example 10 different hair styles). I can use a Sprite Library and Sprite Resolver to switch out the sprite for the hair. The problem is that I have to rig every single hair sprite. (Even if it's copy and pasting the rig this is still a lot of work if you have a lot of different variations). Is there a way to do it while only making the rig once?

If you put all the layer variations into 1 PSB and do auto-weights this works ok, but the problem is if you need to weight paint...because it seems you can only weight paint one layer at a time?

[elfin sandal]

nope, just a quirk of the system

bones need rigged sprites to move them so it can't be helped

[kind yacht]

whenever I make a tilemap, the tile is always bigger or smaller than the grid. How do i get around this??

[static violet]

Hey so I have this character
I am wanting to create a physics based tail for them rather than animating it by hand

There are 2 approaches to this that I'm considering:

1. a code based approach, where I set the offset that each segment should have from the previous segment, and Lerp the value to create smooth movement. This is how Madeline's hair works in Celeste.

The drawback to this approach, is that I have to define alot of offset values that are not very intuitive to figure out initially. The advantage however is that I can have very direct control over the psuedo-physics here and not have to deal with blackbox unity components/systems, and I wont run into any unexpected behaviours.

2. create some sort of spline, chain, link? I'm not sure what component to use exactly for this, but I know there is one that would suit this task perfectly. Disadvantage is that I have to control its behaviour through the component, which involves tweaking and fine tuning values, and depending on situations or behaviours I want, it could be very difficult to get it to behave the way I want.
   The advantage to this approach is alot less initial work.

I'm just looking for others thoughts or opinions on this, or how you would do it if you could think of a different approach

https://giant.gfycat.com/PotableSingleIcelandgull.mp4

[solemn latch]

There isn't really a good built in solution that would work similarly to that, unfortunately; there are a variety of options with their own benefits and drawbacks.

[static violet]

I do think there are components for this, like it wouldn't be much different than making a chain

[solemn latch]

Well, I suppose it depends on what you're doing. For instance, built in 2d physics don't play very well with animators, while spring bones need some script updating to get working since anima2d was depreciated. If you need squash/stretch rather than a rigid chain, that is an additional consideration.

[static violet]

I'm aware of animators vs physics. I dont use the animator for any of my movements, all of it is done via a 2D player controller on a kinematic rigidbody2d

hard coded psuedo physics

[modest cargo]

If the position of the tail's attachment point changes without inertia or teleports, such as when flipping the sprite or jumping, then a physics based system is likely to flip out
I think your best option is to code propagating motion on a chain of transforms, using something like this
https://youtu.be/9hTnlp9_wX8
There's many ways to make object chains depending on how it needs to work, and I can promise you'll be "tweaking and fine tuning" a lot regardless of the path you choose

After that you have the choice of representing the tail with multiple sprites or a line rendered along the tail points which is then pixelated in post

[static violet]

instant teleporting would cause issues with a physics based approach for sure, but I think this can be overcome by using code to clamp the max distance each segment can be from the last one. I expect fine tuning in any case, but getting it to work initially is going to be a task

in any case, I've been thinking on it all day, and I want to pursue the hard coded psuedo physics if I can get it to work.. that video you linked looks really relevant, and I'll give that a watch too

Ive also had a pixel perfect camera component on for a long time, but I'm finally considering taking it off, because the benefits it provides are starting to be outweighed by its drawbacks

and all the assets I've made are already to pixel scale anyways

[solemn latch]

Oh, and of course there is also the option to just draw six tail pose variation sprites and swap them based on the velocity 😄

[static violet]

https://giant.gfycat.com/RapidCelebratedHectorsdolphin.mp4

I did it

even got a bit of code in there to control the tail wagging on running and idle states

I ended up going with the Celeste-like coding method

[solemn latch]

Looking good

Oh yeah, and that actually is one of the things that the built in 2d physics is bad at- changing character direction. The coded version makes quite a nice transition. 😄

[solemn latch]

I actually had trouble with that for the tail of my first character 😄

[crystal flax]

I want to detect what tile I click on using tilemaps. I can do this (pseudo):

//
//
tile = tileMap.GetTile(position);```

This way I can detect the tile I click on at the tileMap I assign from the inspector. But I have multiple tilemaps so I'm not sure how to detect it without assigning a tilemap first. Thanks in advance

[modest cargo]

I think you've got two approaches generally

1. Detect the tilemaps under cursor first. I'd like to use OverlapPoint but since that doesn't return the results I think the option is a Physics2D.Raycast check that's the length of zero or very short, then do GetTile only on the highest poisition Tilemap
2. Have all references to all Tilemaps to start with, do GetTile on a loop on all them sequentially that stops as soong as it finds a tile at that position

[crystal flax]

...

that makes perfectly sense

Thank you. I already have tilemap references, I'll give the second one a try

[shut fern]

Anyone know how to export a level tilemap from one Unityproject to another?

[modest cargo]

My first attempt would be to make it a prefab, select the prefab and export as unitypackage with dependencies

[flat gyro]

When ever I import a sprite sheet everything gets corrupted, there will be blue splotches on the face and other splotches of colors, it's not the software I use or anything I checked various times so I think it's unity.. can anyone help?

[modest cargo]

It may be useful to show an example
It sounds like the usual texture compression artifacts though, which you can get rid of by setting compression to none

[flat gyro]

Ah ty I'll check that later

[paper pendant]

so I'm trying to programmatically make an isometric wall

and it works as a single layer, but if you do a dual layer (i.e. attempt to add height), it does this. I'm guessing its due to sort axis' and rendering order but I'm not sure. Does anyone know a workaround if there is one?

[flat gyro]

That is what it was!

[inland tendon]

anyone know a good tool for making 2d spritesheets?

I wanted to use paint.net but unity apparently struggles to read that format

[paper pendant]

ah okay so for anyone curious: I just needed to set sorting order thru the renderer, easy peasy!

[paper pendant]

use aseprite

Its the 2d art program, no lie. does animation even

[uncut forge]

Just export to png

[paper pendant]

yeah or png

asperite is pretty awesome still tho, its like 20 bux for a suite of tools that slap

[uncut forge]

Can unity use vector images?

[inland tendon]

can someone tell me what's going wrong here? I tried making the image to the right in photoshop, but when it was imported it became the image on the left.

[uncut forge]

Set filter mode to point, and compression to none in import setting for the image in unity

[inland tendon]

!

love you

[flat gyro]

Piskel is a good free one that does animation and can export it as spritesheet

[inland tendon]

Nevermind, I love you more than that last guy

[shut fern]

Thanx I`ll try that ..

[crystal flax]

is there a way to prevent placing sprites on top of each other using unity's tilemap?

[flat gyro]

💖

I also made this with Piskel and Unity

anyone know how to have a shadow caster 2d on a tilemap??

[vapid jewel]

i can't see any sprites rendered in my scene view.
using latest unity 2023.1 beta and URP..

does anyone know how to fix this?

[solemn latch]

Make sure the sprites are not behind the camera.

[novel timber]

how did you make this camera system

[static violet]

do you mean eliminating tears in the tilemap?

look into Pixel perfect camera scripts

[modest cargo]

Gaps in tilemap can be fixed by pixel perfect rendering
Gaps of color in tilemaps may be fixed by that as well, but the root cause is lack of padding between tiles on the sprite sheet

[analog widget]

is it possible to make the shape of a shadow caster the same shape as a tilemap collider?

[floral siren]

hey I have trouble understanding how do i set my game window to be exactly 320x180 in unity, cam anyone point me in some direction? I did set the game view to 16:9 but it'd like it to set it to the mentioned resolution so that it fits 40 tiles in width (Ive created 8x8 tiles). Am I missing anything or do I have to just manually resize the window to fit as many tiles as I want

[novel timber]

How do i enable this pixel perfect rendering

[modest cargo]

https://docs.unity3d.com/Packages/com.unity.2d.pixel-perfect@5.0/manual/index.html It's a component from this package
If you're working with Cinemachine or URP, note that Cinemachine requires a vcam extension for it and URP requires the 2D renderer for it

[novel timber]

Hm, i am watching a tutorial and for now i only added this pixel perfect component, but it upscales camera viewport

[modest cargo]

I should've given a heads up that pixel perfect rendering is not just a component that fixes problems, it's a workflow for constraining screen resolution, camera size and sprite PPU values all together

for ultimately producing pixel perfect results

[novel timber]

i cannot fully understand what you are saying

english is not my native

What to do if i want the camera size to stay at 4.8? As soon as i click "Run In Edit Mode" in pixel perfect camera it changes to 4

[modest cargo]

There is no simple answer to that because it depends on pixel perfect camera's reference resolution

[novel timber]

so i just need to test it?

[modest cargo]

I don't actually recommend using the pixel perfect camera if your goal is to just fix the color bleed between tiles

It's a good system for what it does but it takes a lot of learning and it has its limitations

If you only want to fix the color bleeding, then you need padding between tiles on the sprite sheet as I originally mentioned

[novel timber]

How do i set that up

[modest cargo]

A. Modify the sprite sheet in an image editor so that each tile has 1 pixel of padding in each direction
or B. Generate a sprite atlas in Unity which has the option to add padding automatically

A sprite atlas is not really intended to fix this specific problem either, but incidentally helps
And it's not as complex as pixel perfect rendering

[novel timber]

Where do i set the padding?

[modest cargo]

The sprite editor cannot do it

You need to modify the image itself in an external image editor, then slice it again in sprite editor

[novel timber]

i thought you meant sprite editor as image editor

what do you mean by external image editor?

Inspector?

Its my first time working with 2d in unity

[modest cargo]

I mean not Unity at all, but an image editor like Gimp or Photoshop
Aseprite can do the operation automatically very easily but it's not free

Because of that generating a sprite atlas is probably the simplest way
https://docs.unity3d.com/Manual/class-SpriteAtlas.html

damn

[thorn star]

orthographic camera strikes again, with a very large difference between scene view and game view... The shader i am using is one that allows me to have animated sprites, i would reckon that this is not the issue, due to the fact this issue does not occur on other animated sprites with the same shader. The skybox background is definitely black btw. It almost seems like the orthographic camera is not clearing the pixels, or something odd like that... Are there any workarounds?

ah discord compression has kinda ruined those screenshots.... the pink lines are much more visible than discord shows

[lean estuary]

Pretty weird issue. Have to narrow down the problem if it's a shader, or rendering pipeline maybe.

[thorn star]

ye it is odd, and im not really certain how to narrow down the issue, but so far i reckon it might have something to do with the mesh? As for quads the lines appear on the left side of the tiles, but for cubes the lines appear on the right side of the tiles... weird

[lean estuary]

Narrow down by swapping shader, assets shader is using. If it happens in a specific configuration

[thorn star]

can't really swap the shader, or else there is no issue, this is an animated texture where the issue is only present on the 2nd frame

doubt it is the shader though, or else changing mesh wouldn't affect it, atleast as far as i know

[lean estuary]

Maybe something off in that shader. Try leaving in only necessary parts to test it, no animation and swap manually to test

only minimal nodes

[thorn star]

ok ill try that and report back!

[lean estuary]

just leave the sprite swapping node and feed index values manually to it.

Just to strip down to very basics and remove all possible interference.

[thorn star]

Ok I've stripped it down to this and the issue still occurs, fascinating! Also upon unmaximising the shadergraph window i got this error.

[lean estuary]

Could possibly be a bug in Flipbook. What version Unity are you using?

[thorn star]

2022.2.5f1

[thorn star]

i doubt it is a bug in flipbook, cause why would a different mesh cause the issue to happen on the other side?

[lean estuary]

oh, does it happen if you use some base Unity sprites?

[thorn star]

ooh i dont know, ill quickly check

[lean estuary]

or at least change the order of sprites

[thorn star]

ill also check that then!

[thorn star]

having it as black then pink gives me the same issue as having it pink then black, except now the line appears on the opposite side of the tile, in the same way that changing the mesh does

[lean estuary]

and using any unity sprite?

[thorn star]

still trying to find a unity sprite, i remember finding tonnes always, but now i seemingly can't find any....

[lean estuary]

UI stuff has plenty

[thorn star]

thanks ill check there then!

i remember there used to be a way to open up a window that would allow you to look through all textures in a project, unity and not unity, does this window still exist, is there a shortcut for it?

[lean estuary]

texture property on the material would open asset browser

[thorn star]

aha that is how you access it! I always forget you have to create a new material to bring up the window!

[lean estuary]

Target button on the right of it

Oh, just realized it's not going to work, it needs atlas

[thorn star]

what is an atlas?

[lean estuary]

Does your atlas asset uses any compression, filtering? Try turning that off, maybe bleeding in

An asset with several sprites

[thorn star]

didn't know you could even do that lol, sounds cool

[lean estuary]

Aren't you passing atlas to the flip book?

[thorn star]

ok turns out that it is really difficult to find a unity texture that would work to test this, as most are a solid colour throughout, and the ones that have different colours in each half usually have some sort of transparency around the edges...

[thorn star]

no?

i dont pass any textures or anything to the flip book

i use the flipbook thing to sample the texture though

[lean estuary]

I mean yea, flipbook helps to walk through the atlas turning width and rows to simple indexes. I think.

So if you are not using an atlas you don't really need the flipbook

[thorn star]

i don't know if im using an atlas or not lol... I don't think i am, but i might be accidentally using one

[lean estuary]

I think I've linked this already. Here you can see how sprite atlas dimensions are being set and atlas itself. https://youtu.be/gEnsciDtbUQ?t=132

[thorn star]

ok and ye I can't work out if this is affecting unity sprites or not

[lean estuary]

If you are not using atlas and just entering sprites that would cause anomalies

[thorn star]

ye i tried to follow that, i think i did it somewhat well lol, I'll watch it again though

[thorn star]

ye, i only enter 1 sprite

[lean estuary]

So either put them into atlas or just swap sprites without flipbook manually,

[thorn star]

which do you reckon would be easier?

[lean estuary]

With flipbook you can create animation timer inside the shader and expose some controls. With regular shader you would animate like you previously did with coroutine.

[thorn star]

I'll do it the flipbook route then

how would i create an atlas?

[lean estuary]

in any image editor put then on a grid

[thorn star]

oh, i might already be using an atlas then?

[thorn star]

ok, from rewatching it seem I'm doing this basically the same, except that I'm using modulus instead of animation to control which tile to show

[lean estuary]

Make sure that atlas dimensions are setup correctly as well

width and height on flipbook

[thorn star]

yup, 2 width, 1 height is correct

[lean estuary]

Also no compression or filtering, it may have been bleeding in. On the atlas asset

[thorn star]

ye it has no compression or filtering:

[lean estuary]

It should have sprite mode multiple I think

[thorn star]

ah ok I'll try that!

[thorn star]

the problem persists sadly

[lean estuary]

then maybe leave it alone for now and do it with coroutine. You can detail the problem and post it on the forum, might get solved there.

[thorn star]

Ok! Btw which forum, as there are 2 official unity forums, atleast as far as i know lol

[wary plover]

Hello guys i am very new to unity and i wanted to ask how to check if a game object left the camera in a 2d game i tried googling it but i didnt find anything that worked for me can someone tell me how
?

[orchid thicket]

make a check for the position, and make the gameobject destroy if it goes out of bounds

Also, i need some help, i need help creating an animation from the PNG frames. I drag all the frames, but it keeps flashing, and its not really smooth

[tall current]

Heyo, I'm trying out the 2D shadows with 2D-URP.
When the light I'm controlling with the point goes too far away from the object being lit in the scene, the object ignores all other lights too.
There shouldn't be anything different from the light I can control compared to the non-moving ones.
Is this some shadow-option I'm missing?

[upbeat edge]

When you're importing sprites, is there some way to make them full squares when using a tilemap instead of using their custom physics shape? Here's my settings, which I had wrongly assumed were doing what I wanted 😦

(Mesh type being full rect and generation of physics shapes disabled)

[solemn latch]

No, it is just that their 2d shadows are terrible 😛

[upbeat edge]

This is getting pretty annoying -- I can't view my rule tile in the tile palette, because I'm only using the gameobject property. If I do use the sprite property, the sprite doesn't disappear when the gameobject is removed in the game..

Is there some way around this? I am sick of losing track of it, and I'd rather not make a "YOUR RULE TILE IS RIGHT HERE" sprite in my tilemap, haha

[upbeat edge]

At the moment I am thinking that each tile needs a reference to the tilemap it's on, and then deletes the tile in its cell when it is destroyed

[woven quest]

Hi all! Can I ask for some help please 😅 When import a PSB into Unity. I have layers for each sprite frame. But Unity cuts away the empty space around my layers. How can I force Unity to use the entire layer instead of cutting out the sprite?....On the left is the photoshop layer, on the right is the cut out sprite in Unity.......Why this is a problem is because the pivot is now off, so the sprite is "jumping" around in the animation.

[uncut forge]

You can edit the pivot in unity

[woven quest]

I know but I don't want to manually fix all the pivots, that's going to take a long time to get right

[elfin sandal]

have you tried import mode: merged

or activate/deactivate automatic reslice in import settings

[woven quest]

Hi! Thanks for the ideas! 😁 The automatic reslice doesn't seem to do anything. The merge one actually works to keep the spacing, but it throws all my layers on top of each other. So that's not going to work either.

[elfin sandal]

Oof srry to hear that
I do recall flipbook animation being used with psb importer in a unity video tho
I forgot the timestamp but it was aunity presentation of the animation package

[woven quest]

https://youtu.be/b2bIh8WPsi4?t=325

If you're talking about this one. It's hard to see if his scene has the same problem. He doesn't mention or explain an option for it at all. Which makes me feel his scene has the same issue. Scratch that, his scene does actually have the same problem. You can see the bottom shadow of the butterfly hopping up and down.

Another comment proving the same problem.

Is there an official Unity person we could tag in this problem? Seems like a real issue.

[elfin sandal]

Best place to do it would be forums

[woven quest]

https://answers.unity.com/questions/1938672/psb-import-keep-layer-size.html

You mean here?

[elfin sandal]

Thats unity answers
Forums is seperate
Theres a 2d dedicated section in the foums with a pinned thread about 2d features that the 2d devs are part of and check regularly

[woven quest]

Awesome I did this, thanks!

[plush prairie]

Hi, I created a tile and imported into unity and the colours are a bit off

Image 1 is what it looks like in Aseprite and how it should look
Image 2 is what it looks like in Unity

is anyone able to help pls?

[modest cargo]

Disable texture compression in import settings

[plush prairie]

perfect, thanking you! 🙂

[modest cargo]

@spring crypt More of a #🖼️┃2d-tools question, the two main ways are to have a stack of multiple ortho cameras of different sizes for each layer, or to average an object's transform position with its start point and the camera's position to some proportion
A an object that inherits 100% of camera's position is virtually at infinite distance
at 0% it's in the foreground, 50% somewhere in between and at negative values it seems to pop out from the scene towards the camera

[spring crypt]

I see. That makes sense, thank you.

Another question I have that is bugging me, if you don't mind answering, is why is this character unable to render on top of everything else? I have tried literally everything but it just won't work lmao. Tried sorting layers, messing with the game objects z position, nothing works

[modest cargo]

Canvas by default is rendered on top of everything else, and uses vastly different units for scale
Here it seems you're attempting to bring your sprite character into the canvas image space

[spring crypt]

And the final one is, I don't quite understand the interaction between a canvas and a 2D camera here. Why is this camera white square space so small compared to the canvas? Should the camera adapt to the size of the canvas or is it the other way around where the canvas should adapt to the camera? I have a canvas here that is holding 2 background images with these settings (So that the images that are supposed to be parallaxed fit to the player's screen aspect ratio and resolution at all times)

[spring crypt]

Oh I see, so I should not be using a canvas for this? Or do I just change some settings around?

[modest cargo]

Think of sprites and canvas as entirely separate things for now
They exist in the same 3D space even if they're in a mode that doesn't let them interact

Canvas treats scene units as pixels, other gameobjects treat them as meters

[spring crypt]

Ohh I see, so these white squares that represent them visually inside the scene are just that, to make me aware that they exist there?

[modest cargo]

So what you want to do here is bring your character back into the view of the camera, and make it reasonably small again instead of hundreds of meters tall

[spring crypt]

Ahh, that makes sense.

[modest cargo]

I like to hide the canvas from the scene view using this eye icon next to the Canvas object when not editing it because it tends to get in the way
You should normally use the canvas only for UI and stuff that needs to be rendered on top

[spring crypt]

Could you help me understand why is it that the camera here when in the scene shows blue empty space as if it is looking at nothing at all, but when I switch into game view, it shows me the correct BG images?

[spring crypt]

Oh i see, that makes sense. Thank you! So whenever I want to place these background images for my game orr any game asset really, like the characters, ground and stuff like that, I want to place them inside the camera space and leave the canvas for like UI buttons or text that render on top of those images?

[modest cargo]

The scene view is seeing only the lower left corner of your canvas, so you can't see much
This is due to the unit difference

[modest cargo]

Generally yes
You absolutely can use canvas for background images, but the canvas needs to be in screen space - camera or world space mode, which changes quite a bit how it works
Canvas is meant for elements that adjust to changing screen size and aspect ratio, which is an useful feature but you can also get tangled up in those systems and end up with stretchy city backgrounds unless you know how to work with it

[spring crypt]

Yeah, that is exactly what I wanted to avoid to happen about having stretchy images. I want the images to adapt to the player's screen aspect ratio so lets say someone is running the game in an uncommon resolution/aspect ratio of idk 800 x 750 or something like that or on a wide screen monitor, so I'm trying to understand how the canvas works. but you helped me a lot already! Thank you ❤️

[modest cargo]

Canvas scaling and anchor points can take a while to wrap your head around so I recommend to stick to sprites in front of the camera when you can when starting out

I have this old demo about the kind of parallax systems we talked about initially
Not super elegant but may be useful
Let me know if it's broken or something

[spring crypt]

Alrighty <3. Just to make sure, this is what you meant before right, so now my canvas has my main camera set as the render camera and the canvas adjusts to the camera. But the character remains not being able to render on top of it

[spring crypt]

Sweet! Thank you so much. Appreciate that

[modest cargo]

Don't try to put sprites or other non-UI gameobjects into the Canvas hierarchy

Images and sprites use different sorting methods

In fact try to work without a canvas at all for now is what I'd suggest
Only add it in when you need icons for lives or score or such

[spring crypt]

Alright. Will do that, ty

[spring crypt]

Can anyone help me out here? I wanted to know why is it that when I press play on the game the camera is actually showing stuff that it should not be showing. I thought the only visible things whenever I pressed play would be the stuff inside the white camera square on the scene.

Why is it showing the bottom part on the game scene? 🤔

[elfin sandal]

is it a perspective camera

[spring crypt]

Settings on it:

The camera is basically also attached to the character

[solemn latch]

You have a camera follow script that seems to be moving the camera significantly closer to the character than it is in your scene view.

[spring crypt]

Hmmm

Ill post this under code help

[solemn latch]

I mean, that's a very basic script but it isn't broken. It is doing exactly what it is supposed to do.

[modest cargo]

Maybe you'd want to use transform.position.y instead of target so it won't follow on up/down axis

[solemn latch]

using UnityEngine;
using System.Collections;

public class SmoothFollow : MonoBehaviour {

    public Camera cam;
    public Transform[] targets;
    public int targetIndex = 0;
    public float height = 5.0f;
    public float heightDamping = 2.0f;
    public float horizontalDamping = .5f;
    public float zoom = 10f;
    public float zoomSpeed = 4f;




    void Start()
    {
        if(cam == null){
            cam = gameObject.GetComponent<Camera>();
        }

    }


    void LateUpdate () {
        if (targets[0]==null) return;

        float wantedXpos = targets[targetIndex].position.x;
        float wantedHeight = targets[targetIndex].position.y + height;

        float currentXpos = transform.position.x;
        float currentHeight = transform.position.y;

        currentXpos = Mathf.Lerp(currentXpos, wantedXpos, horizontalDamping * Time.deltaTime);
        currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime);

        transform.position = new Vector3(currentXpos,currentHeight,transform.position.z);


        if(cam){cam.orthographicSize = Mathf.Lerp(cam.orthographicSize, zoom, zoomSpeed * Time.deltaTime);}

    }
}```

Or just use cinemachine 😄

[spring crypt]

Yeah someone else pointed this out to me LMAO didn't know that existed

[solemn latch]

That's the camera script from my first game and it can handle a lot

[spring crypt]

There is just too much stuff, haahaha. Is there some list around here with like "must have plugins" to just make life easier on usual game dev tasks?

[spring crypt]

Thank you ❤️

[solemn latch]

I think cinemachine is absolute overkill for most 2d games.

The main reason to use cinemachine would be if you need the collisions and stuff it can handle.

[modest cargo]

Mesh confiners and blends are quite nice
I agree though most of its features are designed specifically for 3D cameras

[solemn latch]

Well, my script handles blends pretty nicely 😄

[modest cargo]

It handles one type of blend, Cinemachine is great if you need more
Personally I'm not a big fan of the "accumulative" use of lerping, but I don't think it causes many problems
The main concern is that exponentially slowing camera motion can cause shimmer or jitter with pixel graphics

[thorn star]

it has been 3 days with no reply to my forum post, is this normal?

[solemn latch]

Well yeah, it was designed for a non pixel art game before cinemachine or pixel perfect existed.

[solemn latch]

Yes.

[thorn star]

ah, welp... thanks!

[solemn latch]

Especially if you aren't replying to a thread a dev is already watching.

[thorn star]

i don't even know what threads are lol

[solemn latch]

Forum topics.

[thorn star]

they sound familiar

[solemn latch]

Link your forum post?

[thorn star]

https://forum.unity.com/threads/orthographic-camera-displays-differently-to-scene-camera.1397227/

[solemn latch]

Yeah, something fucky is going on there.

Is your camera facing the right direction?

[thorn star]

pretty sure it is

[solemn latch]

Did you try turning off the rest of the crap in the scene? The rest of the 4.3k triangles the inspector says are in your scene?

[thorn star]

it is randomly generated terrain, but i can lower the generation distance

2.2k triangles is the lowest i can go, with prefabs taking up most of them

with generation distance of 1 (1 block in all directions from the player), the pink lines still appear on those few generated blocks, odd

[solemn latch]

Why do uou need ANYTHING in the scene?

Aside from the thing you're testing.

[thorn star]

true, but it would be a real pain to have to bring the stuff back afterwards

i can't just create a new scene with only those weird blocks, cause I'm using ecs, and i have a ton of systems which are looking for things to be in the scene, and if they don't find it, they throw a whole bunch of errors

i suppose this could be an issue with however ecs does rendering? Then again this could be an issue with almost anything, and it is a bit of a nightmare to try narrow it down...

[solemn latch]

Make a new scene

Bring in the trouble object

[thorn star]

can't, SystemBases and ISystems run regardless of scene

[solemn latch]

See, this is all stuff you didn't list in your post and any of these things could be contributing to the problem.

[thorn star]

wait im an idiot, shaders render in editor mode, so i dont need to do this in playmode, hold on while i try this!

[thorn star]

good point, sorry lol, ill edit it

[thorn star]

ok, great but very confusing news! It isn't specific to the orthographic camera, projection camera does this aswell, and it doesn't seem to matter if the cubes are gameobjects or not!

ok from lining up the scene camera as close to perfectly as i can, I can sort of see the pink lines in scene view!

looks like this oddness is near pixel perfect

[solemn latch]

I don't see how this is even a #🖼️┃2d-tools question, so no wonder nobody there is answering

[thorn star]

welp it used to be a 2d question, it has evolved though, so now it isnt even 2d related lol

[solemn latch]

You also haven't even said what render pipeline you're using

[thorn star]

scared to move channels though, cause i dont want the mods to get angry

[thorn star]

oh urp, sorry my bad

[solemn latch]

I think that what you really need to do is try to figure out, if not what is causing it, at least what the problem actually is.

[thorn star]

how though

[solemn latch]

And then you'll be able to write out a question that peeps can potentially help solve

Well, first of all try and actually describe your scene and what is going on in it, since I still have no idea.

Try the shader in a fresh project

Debug your meshes

[thorn star]

ughhh, fresh projects take about an hour, my computer is not very fast lol

[thorn star]

they are unity meshes though

[thorn star]

bare minimum reproducible setup: get a sprite that is twice as wide as it is tall, have 1 half be black, the other half be pink, chuck it into a material using that shadergraph shader, then put it on a cube, on the very edge there will be pink lines

[solemn latch]

That really just sounds like you need padding in your UVs.

If that's all

[thorn star]

what are UVs?

[solemn latch]

...yeeeah, I think I am seeing the potential problem here

[thorn star]

this is my first time doing a 2d game, I currently don't know much about shader lingo, sorry lol

[solemn latch]

UVs are the texture coordinates of the mesh.
