[thorn star]

oh ok cool, how would i add padding to them then?

[solemn latch]

The flipbook works by manipulating the UVs.

[thorn star]

ok, that make sense

[solemn latch]

Generally, you edit either the texture or the mesh to have the UV borders have a bit of space to avoid bleeding

[thorn star]

ok, which do you reckon would be easier/better, editing the mesh or the texture?

[solemn latch]

This is assuming you followed the earlier advice from Fogsight?

And changed the texture settings?

[thorn star]

I have no clue, i hope so though

[solemn latch]

Since they are just squares, I'd edit the shader to shrink the area of texture it is capturing a little

[thorn star]

ok, and how would i do that, im not the best with shadergraph sorry lol

[solemn latch]

https://forum.unity.com/threads/shader-graph-texture-scaling.1120375/

[thorn star]

ok cool!

[solemn latch]

Basically, pixels are interpolated so anything RIGHT on the border will have leakage.

[thorn star]

sometimes left though aswell, it depends on the mesh, and the order of the sprite atlas

[thorn star]

assuming i mathed correctly, this should now work according to this forum post? I shall try this and report back!

hmm, nope not working, weird

oh it does

ish

1e-05 scale gets rid of the leakage

but causes this...

going below -1, or above 1, has unusual consequences

[solemn latch]

You really should need only the tiniest offset

[thorn star]

sadly that seems not to be the case, unless I messed up the shader, which i probably did lol

[thorn star]

aha i did mess it up, this has fixed it, and has also entirely solved my issue!

(now how do i mark a forum post as solved?)

[radiant granite]

In the tile palette editor can I add components somehow to tiles? So certain tiles would always have some component?

(I have a component that controls graphical effects for example)

[elfin sandal]

U will have to learn scriptable tiles

Or use gameobject brush for a quick and easy solution

[solemn latch]

honestly I'd just delete the post

[paper pendant]

damn asperite is a dream, but pixel animation is still pain and suffering

[modest cargo]

Editing in or replying the solution is always good
Leaves a track for people who eventually may search on google for a similar solution

Even if a problem would feel dumb in retrospect, it may turn out to be a repeating stumbling block for different people

[thorn star]

ok, yup that is what i did!

[modest cargo]

@radiant granite You should be able to pick a tile in "local" coordinates by adding the tilemap's world position to the chosen tile position
...If my vector math checks out

[radiant granite]

It's a prefab at 0,0

[modest cargo]

Could even have a specific Transform in the prefab denoted as the local origin, if you can't rely on the prefab origin for whatever reason or wish to move it easily

[radiant granite]

That is 0,0 apparently

I just want to have a standard layout for my tilemaps so I can generate maps with any one of them so I want to be able to access everything by it's index

I do tilemap.GetTile(new Vector3Int(0, 0, 0)); and I get that tile whihc I circled

I see absolutely no logical reason for it giving me that tile for 0,0

[modest cargo]

It's the world position of the prefab's Transform component

[radiant granite]

I see, so if I want to think about this in terms of the index inside the tilemap[ independent of the world coords I need to subtract(?) the transofrm coords of the tilemap

but then agian the transofrm is 0,0,0

[modest cargo]

That depends where in the scene the prefab is
You only need to add the offset position if it's not at the origin

[radiant granite]

Okay I will just slap a breakpoint in and checkk the numbers

[modest cargo]

(though the docs don't actually say if Tilemap.GetTile uses world coordinates or Tilemap's coordinates, I assume it's world)

[radiant granite]

I feel like the docs arent too clear on what is going on with tilemaps

But now, armed with a breakpoint, everything is at 0,0,0 I have no idea where it would go wrong

[modest cargo]

If you want tile at (1, 2) but the tilemap prefab is at (100, 100), then your tile should be got from (101, 102) which is the same as (1, 2) + (tilemap.transform.position)

Allegedly the tilemap system is a bit of a tech demo, like the 2D lighting

[radiant granite]

Ah

tilemap.transform.position is 0,0,0 as I expect sadly

Oh well it's okay I will goof around with it, dont want to bother you too much

[modest cargo]

I'm not totally sure what the problem is, but I hope this clarified at least a little
The positions are always coordinates, but you can treat them as indices pretty easily as 1 tile = 1 unit
add (.5, .5) to get to the center of the tile, just in case it's an issue of trying to sample intersections of 4 tiles

[spring crypt]

Hey yall, its me again xD. So, I set up two BG images to be parallaxed in my game, but when I press play and move my character around (I'm using cinemachine for the camera to follow my player), my backgrounds are static, they do not move at all. its like their position is locked or something

To be able to replicate them I set their draw mode to be tiled, Tile mode to continuous and I changed the mesh type to be full rect and the wrap mode to be repeat. Anyone have any idea why this is happening?

[modest cargo]

How are the background sprites meant to move?

[spring crypt]

Here is a video of it

[spring crypt]

So, for the parallax effect I need them to move to the opposite side that the camera is moving right? and the script lets me control the speed at which that happens.

`` using UnityEngine;

public class Parallax : MonoBehaviour
{
public GameObject[] Backgrounds;
public float[] ParallaxSpeeds;
public Camera Camera;
public float Smoothness = 1f;

private Vector3 _lastCameraPosition;
private SpriteRenderer[] _backgroundSpriteRenderers;

void Start()
{
    _backgroundSpriteRenderers = new SpriteRenderer[Backgrounds.Length];
    for (int i = 0; i < Backgrounds.Length; i++)
    {
        _backgroundSpriteRenderers[i] = Backgrounds[i].GetComponent<SpriteRenderer>();
    }

    _lastCameraPosition = Camera.transform.position;
}

void LateUpdate()
{
    float deltaX = (_lastCameraPosition.x - Camera.transform.position.x) * Smoothness;
    for (int i = 0; i < Backgrounds.Length; i++)
    {
        float backgroundTargetX = Backgrounds[i].transform.position.x + deltaX * ParallaxSpeeds[i];
        Vector3 backgroundTargetPosition = new Vector3(backgroundTargetX, Backgrounds[i].transform.position.y, Backgrounds[i].transform.position.z);
        Backgrounds[i].transform.position = Vector3.Lerp(Backgrounds[i].transform.position, backgroundTargetPosition, Time.deltaTime * Smoothness);

        float leftBound = Camera.transform.position.x - Camera.orthographicSize * Camera.aspect - _backgroundSpriteRenderers[i].bounds.size.x / 2f;
        float rightBound = Camera.transform.position.x + Camera.orthographicSize * Camera.aspect + _backgroundSpriteRenderers[i].bounds.size.x / 2f;
        float spriteWidth = _backgroundSpriteRenderers[i].bounds.size.x;

        if (Backgrounds[i].transform.position.x < leftBound)
        {
            Backgrounds[i].transform.position = new Vector3(rightBound + spriteWidth / 2f, Backgrounds[i].transform.position.y, Backgrounds[i].transform.position.z);
        }
        else if (Backgrounds[i].transform.position.x > rightBound)
        {

``

``Backgrounds[i].transform.position = new Vector3(leftBound - spriteWidth / 2f, Backgrounds[i].transform.position.y, Backgrounds[i].transform.position.z);
}
}

    _lastCameraPosition = Camera.transform.position;
}

}``

[modest cargo]

Your camera is not moving, likely because Cinemachine is not used correctly
The CinemachineBrain component should be on the main camera for virtual cameras to be able to move it

[spring crypt]

oooh ok.

And should I be using the 2D camera?

or just virtual camera?

Yaay. Now it works! 😎 👈. nice

[modest cargo]

They are mostly the same thing, except 2D vcam by default has no aim properties and a transposer more suited for sidescrollers

[spring crypt]

But now I can't change the camera size, lmao it won't let me, its a little too big.

[spring crypt]

👀 Oooh, i see.

[modest cargo]

Because your camera is being controlled by CM vcams
I like Cinemachine but it's a whole suite of tools, I don't really recommend it unless you're ready to study the documentation of how and why it works in detail
https://docs.unity3d.com/Packages/com.unity.cinemachine@latest/index.html The first 7 chapters are pretty important to not accidentally misuse the system
It's likely better to go with Pinballkitty's camera script and not worry about all that for now

[spring crypt]

Sweet, ty. I'll take a read whenever I can.

[radiant granite]

I am going insane, it cant be world coordintaes since GetTile takes specifically int-s, and if I change the transform of the tilemap/grid/prefab I get the same tiles back

But it's just not indexed right

[modest cargo]

Actually yeah, it looks to be Vector3int
Which means it can't be floats or world positions like I've been assuming the whole time

[radiant granite]

I think I've found something tho

The indexing does not run from 0, but after that it makes sense and I can get the cellBounds of the tilemap which is the lower left corner

And from there I can iterate the whole thing just fine

But it's no 0,0 but I need not care since I can get the start point

Oh hell yes, I can get the "bound" and just work with offsets from there

[modest cargo]

What's the benefit of cellBounds in this case?

[radiant granite]

Well because the indexes dont start form 0

So I get the bounds and I can tream them "as 0"

 var cellBounds = tilemap.cellBounds;
 var x = cellBounds.x; 
 var y = cellBounds.y; 

 return tilemap.GetTile(new Vector3Int(x+1, y+1, 0));

[modest cargo]

I see!

[radiant granite]

This will get what I as a human would think is at "1,1"

[modest cargo]

That is useful ^^

[radiant granite]

Glad we figured it out, thanks

[ancient ridge]

why i cant see this obstacle?

its visible only when it not at ground

(im not good at english sorry)

[elfin veldt]

OK I'm getting slightly ticked off now by Unity's tilemap system. I've created a sprite with all my tiles, but as soon as I move tiles in the source file or delete tiles the entire tile palette just becomes broken, because the tiles aren't in the same place anymore. So any painted tiles in my levels becomes another tile or just displays a red color for a broken tile... How are you supposed to change things if all your levels break if you make any changes to tilemap sprites? 😠

[pseudo shore]

Did you change the sorting layer for your obstacle tilemap to be higher than ground?

[pseudo shore]

When you slice the tile atlas up do you use the safe mode of saving tiles? I’m new so not 100% that’ll fix it but I haven’t bumped into that issue

[elfin veldt]

Last time now I only exported the sprite again which overrode it in Unity instantly, so didn't have the chance to slice it. But previously I've used 'Smart' I believe, which isn't very smart at all. But if I were to use 'Safe' instead it doesn't really help if it breaks before I even get to that point...

[modest cargo]

Does your sprite sheet resolution change?

[elfin veldt]

@modest cargo Ah, ye it does actually. I think I trim it on export.. 😶

So I assume these are the rules for working with sprites?

1. Don't trim sprite on export
2. Only replace tiles at specific locations if you want them replaced in the game with a new variant
3. Use 'Safe' slice mode
4. If expanding the sprite with more stuff, grow the canvas size in right and down directions

Anything else I should know about?

[modest cargo]

That's about all I can think of
If the sprite slices in .meta file are always lost on resolution change it's better to start with plenty of empty canvas to begin with
I would also give each tile a 1px padding of the border pixel color (or later compile them into a sprite atlas which can be used to add padding also)
Not strictly necessary but sampling errors of adjacent pixels are super easy to run into

[elfin veldt]

Alright thanks. This has been driving me insane. Will read up on the padding thingy.

[spring crypt]

Hey does anyone know what 3rd party tools are popular for editing tile sets? Is the built in unity one good enough to make simple side scrolling games?

[elfin veldt]

yes, or you can use Tiled I think

[ancient ridge]

why i cant see the player??

[valid flame]

When starting a 2d game, are all gameobject living inside a canvas or each gameobject has its main parents as a canvas?

[modest cargo]

No
Canvas is just for UI like buttons, text and images
Sprites are not images so they don't belong in the canvas hierarchy

[valid flame]

Hmmm I see

I wanna make a card prefab for a card game but that has to use sprites and such, but that has then to live inside a canvas to be visible

So it is a bit confusing

[modest cargo]

What do you mean "has to"
Images components can refer to sprite assets
But you won't get them as sprite renderers

[valid flame]

So I should be making my prefab card with sprite renderers and not images? I'm a bit confused on how it work 😞

[modest cargo]

Sprite renderers and canvases are different things for different purposes
It's best to read about what they do and how they should be used

[valid flame]

I think I'm doing it with just empty game objects adding sprite renderer on kt

Yeah reading it right now

[modest cargo]

You surely can do a card game using either but it's important to know about the limitations

[valid flame]

I've seen some tutorials but it's confusing

One goes full canvases the other full sprite render without reasoning on it

But maybe since I'll have to work with texts, canvases could fit

[ancient ridge]

Help pls

[modest cargo]

https://docs.unity3d.com/Manual/2DSorting.html There's many systems of 2D sorting used by Unity, and just by looking at your screenshot it's impossible to say what's wrong

[ancient ridge]

i cant see any object after tilemap

[ancient ridge]

any object with sprite ready

[viral moss]

Hello guys can someone give me a hand I'm going crazy

I am doing this chess in 2d the problem is that it only works in the simulator when I create the build these are not shown neither in android nor in pc
It's like they don't load the prefabs, sprites, colors, etc.
The first 2 captures are the scenes in unity
When I build the build they should look like the other 2 screenshots
But in the created game they look like the first 2, it does not load anything that it creates

If anyone can give me some advice, I would really appreciate it.

Does anyone know how to put an image on top of another image ? I’m trying to put the character on top of the image of the maze, but when I do so the character goes behind the maze image and gets hidden

[slim aurora]

select your player

and add a new layer in the sprite renderer

its worked for me

[solemn latch]

Ui elements are sorted top to bottom.

[modest cargo]

You probably do not want to use a Canvas or Image components for gameplay elements like players or levels
Canvas is practically suited only for UI elements
I would seek out tutorials that teach making 2D games out of sprite renderers

[faint bear]

how do i solve the weird borders ?

[modest cargo]

They seem to be sampling errors from adjacent tiles on the sprite sheet
The most effective way is to add 1 pixel of padding to each sprite so the adjacent pixel is their own color, not the neighbor's

Generating a sprite atlas has the option to add padding automatically

[faint bear]

how do i do this ?

[modest cargo]

Which one?

[faint bear]

adding padding

[modest cargo]

If you're working in a pixelated style make sure texture filtering is set to Point and that mip maps are disabled
Also consider pixel perfect camera workflow

[faint bear]

ok thanks !

[modest cargo]

You'd edit the sprite sheet in an image editor so the tiles are not touching each other with their own color expanded outward
Or use a program like Aseprite that can add padding to sprite sheets
Or assuming you don't want to do that manually and aren't an owner of Aseprite, try the atlas method
https://docs.unity3d.com/Manual/class-SpriteAtlas.html

[zenith pier]

which layer do i select?

[modest cargo]

@zenith pier Those layers are used for physics and 3D culling masks
Canvas elements are sorted by order in hierarchy
Sprite renderers are sorted by these rules
https://docs.unity3d.com/Manual/2DSorting.html
Again, do not mix canvas and sprites unless you know what you're doing

[analog widget]

how do i fix this?

the black tiles

[uncut forge]

Pixel perfect camera. Sprite atlas. Hours opon hours to make a suboptimal system on your own. Change grid size to 99.99. etc, etc, etc.

[stark ferry]

my sprite is currently able to stick to the walls if the player holds a/d, im using a polygon collider for the triangle, does anyone know how i can fix this?

[willow plume]

I've Dm'ed you a possible physics collider solution.

[modest cargo]

It's best to post solutions so others can see them as well
And only bring stuff into DMs when another user specifically wants that

[willow plume]

if that top image isnt really clear then heres the full sized version^

[slim aurora]

is there a possible way to make a animation with 2 images i have?

[solemn latch]

That's pretty vague.

https://www.reddit.com/r/Unity2D/comments/112r768/first_release_of_the_aseprite_importer_package/

[prisma vale]

Wtf is that?

[abstract raptor]

Still fairly new with the 2D tools here. My camera is set up to reflect a Gameboy resolution (160x144) using the Pixel Perfect component. I've set up a tilemap with the attached image, where tiles are 16x16. The import PPU is 100 and I've set the Grid component cell size to .16 x .16.

Everything SEEMS to be looking right - is it?

I was having problems where the tiles were much smaller than the grid size, and I've seen it suggested that this can be fixed by changing the PPU on import... but this doesn't seem to work with the Grid component.

[sinful robin]

Any way to import video with a scaling setting like Point (no filter)?

[elfin sandal]

keep grid size to 1 always

the only thing you ever need to change is the sprites

[abstract raptor]

@elfin sandal

Are we talking Cell Size or overall scale?

If I set the Cell Size to 1, things kinda fall apart...

[elfin sandal]

change the sprite ppu to something else then

[abstract raptor]

With the Cell Size at 1, this is the PPU at 20 (I'd go to 16, but it completely swamps the screen):

This is the PPU at 50:

I can't seem to reconcile the PPU sizes with the grid spacing, @elfin sandal ...!

[analog widget]

how can i make the shadows look sharper?

[abstract raptor]

It really seems like changing the cell size is the only solution to this problem...!

[elfin sandal]

it's not the only solution but the easiest one

you'll have physics problems with collisions since you'll be playing at very small units but that's only if you use anything related to physics

[abstract raptor]

I mean, what's the other solution @elfin sandal ? I grant you that, say, a standard capsule collider dwarfs tiles at this scale. I'm obviously going to be using physics as I intend to run, jump, have projectiles, etc. But if I'm using the Pixel Perfect Camera component, I can't change a lot of related values on the camera...

I'm not opposed to doing work here, but I'm not sure I see the correct path through this.

[elfin sandal]

you changed the sprites ppu but did you also change the ppu camera component's ppu settings

[abstract raptor]

...!

I did not.

That's at 100 atm.

[elfin sandal]

might be why

[abstract raptor]

I think you're on the money. Let me mess about with that.

You are 100% on the money. Thank you, @elfin sandal .

[elfin sandal]

no problem

[modest cargo]

Tbh there's less math to do with PPU values if you standardize editor grid and grid component sizes at exactly 1
The correct pixels per unit should be obvious then

As well as how many tiles/units the reference resolution corresponds to

[abstract raptor]

Roger. Setting the PPU for the assets and the Pixel Perfect Camera component to 16 seemed to do the job perfectly.

[wheat summit]

Guys i wonder if there is some tool for procedural generation for Unity of 2D top-down levels? I remember there was something like that in Heroes of Might & Magic level editor or in most recent game like Archevale.
I dont want to reinvent the wheel so can someone pointy me out if heard/know something about this?
I got tiles in tilemaps so something using this.

[elfin sandal]

Topdown engine has a procedual tool

[spring crypt]

Hey ya'll, morning. I wanted to ask what the "pixel per unit" means when importing a PNG image into unity. What is this value tied to?

[solemn latch]

How many pixels in the texture go into a unit(one meter) in unity.

[spring crypt]

I see, so when importing things, the PPU value inside of unity of said PNG image should be set to match the size of the canvas they were drawn in? For example, this one I got here uses aseprite and the canvas size is 288 x 128. What should the PPU be in unity? Or are these not related at all and the PPU is just a value i choose?

[solemn latch]

It is a value you choose; there is no right answer.

Generally, for a pixel art style you will want to keep it consistent across your assets.

It will determine how large a pixel is in world units.

For instance, folks using tilemaps often base it on that(so that each tile is 1 meter for instance) or based on the size of their character for whatever physics characteristics they want.

Or to fit things into a particular screen size with the pixel perfect camera

[spring crypt]

Ohh I see. Thank you! Appreciate your patience 🙂 👌

[wheat summit]

This one, right?
https://assetstore.unity.com/packages/templates/systems/topdown-engine-89636

[spring crypt]

This reference resolution here on the pixel perfect camera (as it says there) should be set for the resolution I want my game to run at? For example, I want my game to run at a 1920 x 1080 resolution (most common monitor resolutions)

[solemn latch]

The reference resolution is... well, think of it as the screen size you are emulating.

Like for example, to emulate an SNES style look you'd use 256×224 reference resolution and 8 ppu

[spring crypt]

I see, so If I'm just trying to display my game for a common 1920 x 1080 resolution at a common aspect ratio of 16:9 I should just set the reference resolution to 1920 x 1080 and keep Upscale Render Texture on, so it adjusts accordingly to the player's chosen aspect ratio and resolution?

[elfin sandal]

No

Choose a small resolution

[spring crypt]

Why is that?

And do i just choose a random value?

[spring crypt]

Hey ya'll! I have this code here for my character movement (that also accounts for when the player is moving right or left and flips the asset), but whenever I press play, the character is extremely jittery (Its like the camera is shaking or something), as seen in the video. And there is also this error on the console, that I don't know what is. What could be causing this?

[plush ibex]

Hey all! I'm getting started on my first 2D game, I'm looking to use visual scripting for the bulk of the work. Is GameCreator2 a good choice for helping me develop this? The game will essentially be Texas Hold 'Em

[obsidian dagger]

Hey everyone, Hopefully an easy question.. I have multiple images that I would like to be treated as a single object in my assets folder (like a sprite sheet that has been cut). Is there a way I can manually add a group of images together like this?

[small berry]

I don't think so - you'd have to put all images in a single image, then slice them up into sprites

[solemn latch]

Honestly it is probably easier to just see the effects than to explain them now that you know what's going on under the hood

[somber mauve]

When the player goes up a slope, they they float in the air. When the player goes down a slope, they don't. I'm using a composite collider for the tilemap.

[uncut forge]

they are floating on the way down. Try a circle or capsule collider for your player. should help

[somber mauve]

I'm fine with the way it looks going down, but the player is higher than the slope's collider when going up the slope

[uncut forge]

or, if you want to do it in an incredibly horrible way, make the player a tilemap of its own, with each pixel a tile

[uncut forge]

its because your BoxCollider2D extends way past your bird's feet in the front

[somber mauve]

Oh, I see

I'll try a circle collider then, thanks

[somber mauve]

Now that I'm using a circle collider, the player slides like this

[solemn latch]

You could just use a smaller rectangle, or even two squares(for body and head)

[zenith pier]

hey

i am trying to use 3D objects in a 2D project

It looks like this

But I want it to look like this

[modest cargo]

Does the "preferences" button send you to a page with settings relevant to the warning?

[chrome grove]

Nope, it brings me to a page that is blank.

[zenith pier]

is there a way i can increase the thickness of this 2D square

[smoky socket]

what do you mean with thickness? if you mean the scale in the y x or z coordinates you can change that in Transform and Scale

[smoky socket]

@zenith pier we should write here not in coding

also i could make you a wall if you want

[zenith pier]

yes please thatll be fantastic

[zenith pier]

sure my bad

[smoky socket]

is this ok?

[zenith pier]

wow that looks great

i use it as a sprite right ?

[smoky socket]

nah its 90% copy and paste

[zenith pier]

and i make this as a floor, duplicate it 4 times and make walls out of it ?

[smoky socket]

ask someone else about this i just began coding

[zenith pier]

sure np thank u!

[smoky socket]

np

[modest cargo]

You might not see the sprite as it's huge and away from the camera
Remember to follow tutorials and guides when learning Unity

[smoky socket]

does anyone have an idea for an simple enemy

[zenith pier]

@smoky socket

[smoky socket]

This is?

white is ground and pink are walls right?

i don't know what you want to do so i can't judge it

[smoky socket]

if the pink things are walls then i would rotate them (top and bottom)

[zenith pier]

can you help me do that

ive been stuck on that for a long time

[zenith pier]

yeah theyre the walls

how do i rotate that

got it, but what rotation values should i put it to

[lean estuary]

If you are going to scale the asset, keep it under unscaled parent, then you can manipulate it normally.

[zenith pier]

how do i get those as walls

[smoky socket]

Transform -> Rotation x, y, z

oh wait haven't read the middle message

[smoky socket]

just try and error

[smoky socket]

try mostly with 90, 180, -90, -180

[zenith pier]

okay thanks

it looks like this now. i just need to put top and bottom tiles

[smoky socket]

yeah

Are there any tools that sort of work like Unity's tilemap palette? Where you can have a set of tiles and then use them to paint/combine them into a new image?

I need to create various sprites from the base tileset so that I can then create prefabs out of them.

I found this, but its' not working for me https://github.com/leocub58/Tilemap-to-PNG-Unity

anyone know a better way to initialise my spriteshapes? (my linePrefab, is just a spriteShape made into a prefab)

       foreach (TransportLine line in transportNetwork.lines) {

           GameObject road = Instantiate(linePrefab, new Vector3(0, 0, 0), Quaternion.identity);
           SpriteShapeController shapeController = road.GetComponent<SpriteShapeController>();
           shapeController.spline.Clear();
           shapeController.spline.InsertPointAt(0, line.fromNode.worldPosition);
           shapeController.spline.InsertPointAt(1, line.toNode.worldPosition);
       }

Probably what the preferences button is for?

[chrome grove]

Doesnt bring me to anything at all, brings me to a blank preference page with nothing highlighted and some text in the search that doesnt match on the page that its on.

[frank vessel]

isnt that level design?

[valid flame]

In a card game what's the pros of having cards as single gameobject with canvas inside on each one Vs gameobject inside a huge canvas?

[thorny laurel]

why even with point no filter does this look so bad when being sliced

[zenith laurel]

Try setting compression to none, currently it’s set to ‘normal quality’

[thorny laurel]

thank you so much

[zenith laurel]

No problem

[fiery trail]

people

why can't i scale up the text???

[thorny laurel]

how about tile pallet stuff?

is there a way to make those more crisp

[zenith laurel]

Not 100% sure, the only things I would know to change are the compression, filter, and then maybe the max size if it’s a sprite sheet

If the sprite sheet is larger than that max size it’ll compress the image, so if size is the issue definitely try scaling that value up

[zenith pier]

why cant i see the camera ?

how do i fix this

why cant i see any grids in tile map?

[young locust]

ASK

If i want to make tilemap like harvest moon GBA, should i separate the tilemap or make it 1 complete tilemap?

[viral marten]

Hey guys, I am trying to make sprite assets, but when I put the sprite atlas texture into the TextMeshPro Asset Importer, and click create/save sprite assets, they do not show up on the list

The spaces where the icons would be showing are all blank, and I cannot figure out why

Does anyone know?

[raven mesa]

Why is Unity showing me all these extra sprites? The only sprites in my Assets folder are the colored blocks in the top-right and the ball in the top-left

[abstract olive]

Likely from some plugin you've downloaded that's using those and are in their own folders.

[raven mesa]

How can I find this plugin?

[abstract olive]

Unity packages will be in the packages folder.

[raven mesa]

oh, duh. How do I manage these? How did they get here? This is a new project I started today so it must not be per-project

[abstract olive]

They're default packages installed by Unity

[raven mesa]

How do I get them to not show up here?

[abstract olive]

You can add, and remove them from the package manager. You can also download and install assets via the asset store from there as well

[raven mesa]

When I see other people opening this window, they only have their project assets showing. How can I make it look like theirs. I don't want to see a bunch of built-in Unity icons.

[raven mesa]

Whoops, forgot to reply, mb.

[abstract olive]

You can't. You would probably have to figure out which package it was part of and remove the entire package if you weren't using it.

I don't even know if those are from a Unity package, I've never seen them.

[solemn latch]

You aren't using textmeshpro, which is the type of text that scales nicely.

[modest cargo]

this icon being gray means your scene gizmos are switched off

[young locust]

If i want to make tilemap like harvest moon GBA, should i separate the tilemap or make it 1 complete tilemap?

[cerulean dome]

Is there a way to add gameobjects to a tilemap palette? Like a barrel that can be destroyed

[celest tree]

You mean a gameobject on top of the tile, or destroy the whole tile? If destroy the whole tile then just do SetTile to null on the tilemap (ie tilemap.SetTile(new Vector3Int(0,0,0), null) )

If object on top of a tile then just use CellToWorld to find the world location of the tile and then instantiate the object at that position: https://docs.unity3d.com/ScriptReference/GridLayout.CellToWorld.html

You might want to make a class something like GridObjects to add to the on-top gameobject which stores the associated tile Vector3int position; then you can easily FindObjectsOfType<GridObjects> to later find the on top gameobject associated with that tile

[cerulean dome]

@celest tree Is this the way game developers add crates, explosive barrels, chests and other interactable tiles?

[gray ermine]

Does someone know how I can keep the zoom level the same on different resolutions when using Pixel Perfect Camera? Left side is what I want the player to see, that's at 1920x1080. But when I changed this to 1366x768, then it zooms out for some reason. This absolutely cannot happen, as I only want to show the exact arena. I'd like to add black bars, but all of the "Crop Frame" options don't really fix the problem. Letterbox adds bars on top/bottom, but you can still see more of the screen on the sides. Pillarbox does the same vertically. And Windowbox makes the game a tiny box in the middle. Any ideas how to fix this?

[elfin sandal]

Make sure u check run in edit mode

[gray ermine]

There's no run in edit mode in the URP version of the component. It's always active

[fiery trail]

why doesn't the text on my button show up?

I'm having some trouble with my sprite rotating when it runs into small collisions (these grass tiles will not have collisions in the future), is there a way to lock the z rotation in the capsule collider component? Or does it need to be done in the script? Rigidbody?

Nevermind, got it to lock lol

[stiff hamlet]

do they havei colliders?

[dusk thicket]

is anyone familiar with the pixel perfect camera? please let me know if so

[solemn latch]

Alternatively, why don't you just ask whatever question you have?

[dusk thicket]

Fair - I'm in the beginning stages of making a megaman based game. Looking at recent entries, I see Shovel Knight reportedly built towards a 400x240 resolution, which is pretty non-standard. Yet, it's able to scale to 16:9 seamlessly for 1080p. I'm not sure how to accomplish this with the various settings in unity - I also don't know how they did it. I can set the pixel perfect camera's target resolution to 400x240, but then I have to select the "crop to x, y" setting, which ends up letterboxing. Maybe that's fine? Either way, when I go to build settings and set the window to build to 800x480 & allow for window resizing but select 16:9 aspect ratio only, I find that I'm still able to resize the window's height and width independently and make all sorts of crazy resolutions.

I'm not sure where my approach or understanding is breaking down here, so any guidance will be appreciated. Thanks in advance!

Also, I couldn't get anything that seemed to make any sense at all without the "crop to x, y" setting. Without that checked to on, I would get all sorts of arbitrary sizes included in the game viewport and couldn't properly plan out tiles that would be in the viewport.

[modest cargo]

@stiff hamlet The first step is usually to read the manual and/or look at tutorials

[solemn latch]

Use 'upscale render texture'?

hi guys, how to apply exception in tile_rule when in edge canvas? should i add more until outside canvas?

like this?

[fallow kernel]

hello guys, I'm new here and to unity too, I wanna ask a question about pivot point, I have changed the pivot point and it keeps getting changed back, idk why the pivot point keeps following the last order of my assets here. I have spent hours and still can't fix the pivot point

[modest cargo]

From where are you changing the pivot point
Hierarchy or sprite editor?

[fallow kernel]

hierarcy, since idk why my assets doesnt have sprite editor

[modest cargo]

If you do it in the hierarchy, the changes will be overwritten by the animator if you have one

You could show the inspector for the body part gameobject and the body part texture import settings

[fallow kernel]

this is the sprite editor from my imported asset using psb file

[fallow kernel]

ooo i have animation

[modest cargo]

so they do have a sprite editor
You can see the sprite pivot point as the blue circle

[fallow kernel]

but i put it in my character gameobject, even when I remove all the prefab, it still apllying to the lowest asset, which is really frustating

[modest cargo]

I don't quite understand

[fallow kernel]

yes I change all the pivot point to the corner, except for the body

[fallow kernel]

I have removed the prefab, and it still applied to the lowest asset there

like they are not in the middle

and idk why the legs suddenly fall off too, after I remove the prefab

[fallow kernel]

omg thank u bro, i removed the animation, and now all works well

hello how to make custom 2d hitboxes?

like for a spike

[modest cargo]

Custom physics shape in sprite editor

[stiff hamlet]

spazi can u help meh with it

its confusing

like wtf am i doing

[modest cargo]

you're creating many many little rectangle colliders, apparently
You'd have to make just one, click on one corner and delete, move the remaining three into a triangle shape

[stiff hamlet]

what about this?

if thats its hitbox

what about collider

[modest cargo]

There's no such thing as a hitbox, to my knowledge
The physics shape you created will be used as the default Polygon Collider shape when you assign such component

[stiff hamlet]

what collider will use the physics shape?

of the sprite

[modest cargo]

Polygon Collider 2D

Moving characters don't really need an accurate physics shapes or benefit from it, and it's tedious to update the polygon collider component in case of animated characters

I suggest one of the primitive colliders instead

[stiff hamlet]

nah im making a game with no animations

im bad at animations

so only 1 frame

thanks

[modest cargo]

Still it's rarely worth the effort, and the only result is irregular and unpredictable colliders most of the time
Almost every 2D game you can find uses just rectangles, circles or capsules

But that's up to you

[modest cargo]

You probably don't need the collider to be pixel perfect

[stiff hamlet]

its not pixel perfect

im doing it near the pixels

im lazy

[modest cargo]

half of it seems to be

You surely can get away with just a triangle

[stiff hamlet]

i will try both

[modest cargo]

If you really need the collider to match the pixels, there's a script that can do that automatically

[snow ginkgo]

Hi! I don't know if this is the place but.. as you can see here, the bullet is going behind the wall because of Y sorting (the walls pivot is at the bottom) It should go behing it when shooting from above, but not if shooting from the bottom. I cant move the pivot because its correct like this so the characters go behind it as they are supposed to. How do you approach this?

[dapper shard]

Does anyone know what could block the 2D Shadow Caster to block the use of its edit button?

[solemn latch]

You have 'use renderer silhouette' checked.

So that'll override the shape.

funny thing is, it does become available when I try to run my scene, and then it reverts back upon stopping.
So I tried copying the values while in Run mode, and it does seem to work

[rare river]

I'm struggling to find an answer to an issue I'm having with Rule Tiles. I have a game with two tilesets: grass and spikes. I've created a rule tile for each of these separately, as well as a Palette for each.

First off, I'm not sure this is the correct approach, so please let me know if that is my issue.

But my main issue is I'm trying to get these two rule tiles to work together. i.e. a spike tile will detect a grass tile next to it and factor that into it's rules. As you can see, right now they don't work together and I'm trying to figure out how to resolve this.

[stable mauve]

L response, i tried couldnt find any good documentation

yeah you're mad weird for this, bro didnt ask to ask he just asked lmao

[brave adder]

Hey I want to import this sprite

and this happens

[ionic shore]

my first pixel animation

vs my third (after watching tutorials) the tutorials i watched were rly well explained by "BAM animations" who give a very good explanation of the fundamentals of animation

[brave adder]

I think I fixed it, I dont really know how materials work

just shuffeled them around until it worked

[ionic shore]

nice

[brave adder]

there is still this wierd shape around it

and 2 dots

[ionic shore]

what software r u using?

cause you could've forgotten to delete the backround

[brave adder]

thats how it looks like in unity

[ionic shore]

oh

[brave adder]

and the image is png

deffinetly doesnt have any backgroudn

[ionic shore]

kk wait lemme check something rq

[brave adder]

at least it works :D

its super smol tho, can I just make it bigger in unity or will I need to do it in another program?

[ionic shore]

i just scaled my player object up and if you need to just change the hitbox

OH I KNOW

[brave adder]

my square guy works now!

[ionic shore]

nice

[brave adder]

hes finnaly red

[brave adder]

oh I can scale it up...

Okay

Im just

dumb

[ionic shore]

no dont do that

[brave adder]

why?

[ionic shore]

theres a better solution

cause scaling it up can cause some wierd positioning stuff that can mess up stuff

i forgot what its called but im opening my unity up rn to find out what its called so i can tell you how to fix it the proper way

[brave adder]

oh okay

thanks

:D

nice animations btw

[ionic shore]

its 1/2 loaded its pretty slow

ok\

click on the player sprite png

go to inspector

click on pixels per unit

and whater pixels ur character is change it to that

im guessing your character is 32x32

so just put 32 into the pixels per unity

then the sprite should be normal

there

if its blurry just tell me, if not then just leave it alone

[brave adder]

Ohh

it works :)

thank you

[ionic shore]

np

is it blurry tho?

cause sometimes when you do that it makes it blurry so you have to change the filter to "point (no filter)"

[brave adder]

nope

[ionic shore]

alr then your good

also google is ur best friend for problems

i learned that from a youtube video

and trial and error

and i also look at unity forums

those help a ton

i have one month experience with unity

[brave adder]

ohh nice

I just started today

[ionic shore]

so i have a ton of issues

[brave adder]

my goal is to make a game similiar to cuphead

idk how long it will take

[ionic shore]

i am actually stuck on my project rn and am waiting on a forum reply bc im having camera issues with trackign the player

[ionic shore]

maybe a year or two if you make it a smaller version with everything a little bit more minimal

[brave adder]

do you know why it has these wierd borders?

[ionic shore]

i actually dont

maybe ur software?

what were u using?

[brave adder]

I just installed these from the unity assets thing

[ionic shore]

oh

ok

then its unity

[brave adder]

the image doesnt have it

it only shows on unity

[ionic shore]

send a screenshot of your inspector for the png

[brave adder]

this?

[ionic shore]

ok ill compare to mine

[brave adder]

its not really that important, I can use my square guy

now that I know how to scale him up

or down

[ionic shore]

naw graphics are important in a game

did you just drag and drop the png into the game scene?

cause i cant find a difference

[brave adder]

my game is basicly 3 platforms and a script that allows player movement that I stole from a yt vid lol

[ionic shore]

oh bendux?

yeah i did that too

[modest cargo]

Usually due to not using correct material for sprites

[brave adder]

to the player sprite renderer

[ionic shore]

oh ok then thats not it

[ionic shore]

how to fix?

[brave adder]

oh yeah

its fixed

thanks @modest cargo

[brave adder]

Yeah hes like the best youtuber ever

[modest cargo]

Do you have the same issue?

[brave adder]

he replied to my problem in like 12 mins

[ionic shore]

no

[brave adder]

Also it seems that flipping doesnt work for me

from the yt video

but thats probably a code problem

yep, it was a code problem

a very simple to fix code problem

anyways thanks a lot for the help

35min past!!

time flies by so quick

wtf

[ionic shore]

lol ikr

i didnt notice either

[reef violet]

is there an app to make assets like that

so in pixels

that you can color a pixel in by clicking on it

[modest cargo]

Pretty sure almost all drawing / image editing programs work that way
Some are specialized for pixel art, like Aseprite

[tame hinge]

is there a way to know exactly on which pixel a sprite/object was hit?

or at least the general location where on the object so I can approximate the coordinates of the pixel

I know there is a way to know in terms of worldspace

for context I am trying to recreate the disintegrating barrier mechanic from the original space invaders but I have no clue how to solve it

[modest cargo]

You may want to use a destructible tilemap or individual gameobjects for the barrier
Unity doesn't really deal with "pixels" like old 2D game engines do

[tame hinge]

@modest cargo I was gonna do individual objects but having to line up smalls sections of a sprite would be such a pain

if I don't want to just have normal squares but simulate some progressive breakdown

but destructible tilemap? 👀

that sounds pretty interesting

[modest cargo]

Individual gameobjects wouldn't be my first choice, but in case you do need to line them up quickly and accurately you can hold the V key to enable vertex snapping
It lets you drag corners of gameobjects and snap them to corners of other gameobjects

[tame hinge]

I assume it would work if all my sprites have the same dimensions but my other approach didn't have that

so you'd do destructible tilemaps @modest cargo ?

[modest cargo]

That sounds like the best option here

[tame hinge]

thx

unfortunately it won't be like how it works in the original game but I am not competent enough to write my own pixel based collision system yet

[modest cargo]

How will it be different practically?
Unity is a 3D engine through and through so I'd probably favor some other engine if authentic pixel physics are the goal

[tame hinge]

I mean the way I am doing it now is it would just remove a 4x4 chunk of the sprite overall and it wouldn't look like dynamic destruction like in the original

but I don't really care anymore

as opposed to smth like this

[modest cargo]

Why not treat individual pixels as tiles?
I'm not sure how the tilemap handles tiny and dense grids like that, but it's surely worth a try

[tame hinge]

not sure if I would run into similar problems I had when I tried to manipulate the sprite pixels directly

but it might be worth a try, even if it sounds like a lot of work :P

I would have to destroy tiles based on direction of impact and also destroy tiles around it in a "realistic" enough fashion

[modest cargo]

What kind of problems are you predicting?

[modest cargo]

That's exactly the kind of thing tilemaps should be suited for

[tame hinge]

Well, I have to research destructible tilemaps in general first anyway

I know how normal ones work to a degree

Actually I know nothing of tilemaps

@modest cargo since tilesize depends on unity units as everything, how would I even tell it to be a 1px x 1px tilemap o.o

[modest cargo]

This depends on the size of your "pixels"

Which is the PPU value of your sprites

If you want to skip all the math, treat one unit as one pixel and set the sprite PPUs to 1
But I recommend that only if your play area isn't much larger than one screen

[tame hinge]

wait I might be dumb

my ppu is 16

[modest cargo]

The PPU can be anything, but it's most useful to guarantee that tile sprite graphics have a specific resolution
But since you use pixels, sprite resolution is not a meaningful concept

[tame hinge]

Imma play around with it

I have to figure out tilemaps first :P

[tame hinge]

drawing tiles that small didn't seem to be a problem but I wonder how collisions will work

[tame hinge]

although for some reason with the tilemapcollider attached the collisions don't seem to work

did I forget something

OnCollisionEnter2D doesn't fire

ah, it's possible that the collider type isn't working

[modest cargo]

Type not working?

[tame hinge]

on the tile asset itself you can set collider type from none to sprite or grid

grid works though, at least it generated a collider

now somehow have to figure out how to destroy single tiles

tile destruction works but it's VERY inaccurate so far

sometimes tiles get destroyed and some don't, hmm

but it almost works

[modest cargo]

How are you getting the tile from the collision event

[tame hinge]

    private void OnCollisionEnter2D(Collision2D collision)
    {
        int contactAmount = collision.contactCount;
        for (int i = 0; i < contactAmount; i++)
        {
            ContactPoint2D contact = collision.GetContact(i);
            DestroyCells(contact);
        }
    
    }

    private void DestroyCells(ContactPoint2D contact)
    {
        Vector3Int pos = _tilemap.WorldToCell(contact.point);
        _tilemap.SetTile(pos, null);
    }

that's more or less the only thing that makes sense

things that affect which tiles get destroyed are the speed of my bullets and the max tile change count on the collider

the odd thing is, it's always the same tiles that don't get destroyed

I'll try if continuous collision detection changes anything

the ones on the left don't get destroyed for example

is there no way to move my game view if I zoom in btw

As I suspected though, the collider is not working properly

I have a feeling it might be too small/dense?

[modest cargo]

Middle click + drag I think

Or the scroll bars
Assuming you mean the zoom function of Game window

[modest cargo]

Is it one tile per unit, or denser?

[tame hinge]

I think so

one pixel per tile

one pixel is 16ppu

[modest cargo]

So a 16x16 sprite?

[tame hinge]

but I might try a gameobject centric approach instead

it's a 1x1 sprite lol

[modest cargo]

If one "pixel" is 16 pixels per unit, that implies your tilemap is 16 tiles per unit, assuming one pixel sprite per tile

which sounds dense to me

[tame hinge]

it's pretty dense yeah

[tame hinge]

so no way to do it in play mode?

[modest cargo]

Perhaps not by normal means
I never thought about that

[tame hinge]

The game object based approach worked

[modest cargo]

Also, worth noting that what your projectiles are and how you're moving them has a significant effect on their collision accuracy

[tame hinge]

I move them like so

_rb.velocity = shotDirection * _shotSpeed.Value;

shotDirection can be Vector2.up/down/left/right

[modest cargo]

That's good, means you can use continuous collision detection
Moving objects by other means than forces or velocity has a negative effect, and all moving colliders should ideally have a rigidbody

[tame hinge]

good to know I did it right yes

[vague smelt]

Hey, I have 2 questions how to fix some things, first thing is that when I have 2 tilemaps and floor map uses normal map texture, which is sometimes visible through second tilemap created for walls. Second thing is how to make player above this shadow so it will not be clipping player

[devout moth]

i want to do uv-mapping with uv editor like 6 sided cube but there is nothing i can choose. what is the problem her?

[white talon]

noob alert
I've looked everyone for an answer, but I think I'm using poor wording.
I have these huge spite sheets to decorate my interior with, and I was planning to just chop it up and drag what I want into the scene, but Unity breaks them up in such an unorganized mess.

is there a window, an organizer? Something to help with this?

or is there a way to make the images larger in the project viewer

[solemn latch]

[viral tusk]

Hello,

I'm trying to make a checkered rule tile, so when I draw, it automatically makes like checkerboard effect.

This is what I've setup, but it's only green.

I was hoping someone could point me in the right direction?

[astral anchor]

Is there any way to add these "exceptions" with rule tiles?
I want to add a different slope tile that doesn't get auto-placed but it still affects other tiles in the rule tile.
right now, I made a different tileset with the sloped pieces, but its not affecting the rule tile set.
Anyone know what I should do?

[crisp edge]

I'm running into an issue I was hoping I could get some guidance on my tilemap. I have the tilemap collider 2D attached to my tiles, my character does not fall through the ground, but he is able to pass through the sides of tiles and I'm not sure exactly why. If it's a slope, he'll go up the slope but if it's a sharp increase I intended to be jumped over, he can just walk right through them.I may be using the wrong terms when searching but I can't seem to figure out any answer to what's causing this and what I can do to fix it.

[crisp edge]

I figured out what the cause was - I have freeze position x checked in my constraints. I'm not sure why that causes me to be able to pass through walls though.

[modest cargo]

If your character's rigidbody position X is frozen, that means it cannot move sideways by velocity or any kind of force, including push force from collisions

If you can move at all, that suggests you're using some type of incremental teleportation to move (such as .position, .Translate() or .MovePosition()) which ignores rigidbody physics

[crisp edge]

Yeah I was using .Translate(), I switched it to .velocity after doing some more research. Finding out the X position was frozen was the cause helped me look into it a little more

[crisp edge]

It's my second project not following a tutorial so I've got a bit to learn 🙃

[modest cargo]

You should always be looking at tutorials and guides
Even if not following them, but using them as notes

They are not "training wheels"

[crisp edge]

Oh no I meant not a guided "This is what we're gonna make, and now make a script and put this code in it" tutorial.

[vestal tusk]

Unity lost pixels/lowered the alpha of my sprites. Is there a fix for that?
The first image is from the Unity Sprite Editor and the second one is from the software I use to draw stuff.

[zenith laurel]

Do you have the compression set to none and filter set to point?

[vestal tusk]

Yes, but even then, these settings don't affect the Sprite Editor.

[modest cargo]

The max size setting reduces the resolution of your sprites, if they're above the limit

[vestal tusk]

Is there a way to increase it?

[zenith laurel]

Should be in the inspector somewhere, I believe the default value is 2048

The option should be right under the filter setting

[vestal tusk]

Ho it's that thing. I though it was just working in game, not in the Sprite Editor.

Thank you very much

[small moon]

is it possible to regenerate the polygon collider so, when a sprite mask is added, it will redraw the collider to match?

or just some way to make other objects ignore the bits being covered by a sprite mask

[small moon]

I've been researching a bit more and it seems a bit futile to redraw polygon colliders based on the sprite mask, but now I've found a thread here: https://forum.unity.com/threads/2d-polygon-collider-clipping-by-mask.1220580/ that seems to do exactly what I need it to

OP says they solved it by "using layer masks" without elaborating, but I'm not sure exactly what they were doing with said layer masks

their results seem pretty great so I'm curious if anyone has an idea how they did this with layer masks?

they did mention the Clipper library but unless I'm illiterate, they don't say they actually used it to get this result

[vague smelt]

Can anyone help?

[modest cargo]

Although I don't recommend upgrading beyond LTS versions, I heard that overall glitchyness of 2D lights seem to have been reduced in 2022.2.

[vague smelt]

I'm in 2021.3.19f1

hm

[modest cargo]

Including the glitch of it randomly ignoring shadow casters or disappearing

[vague smelt]

normal maps are on side textures too

what is happening

[modest cargo]

It may be worth the try to upgrade a copy of the project

[modest cargo]

I agree about how vague the post is
The user seems to be active still so hopefully they'll reply to my message

[vague smelt]

This normal map glitch still happens

[modest cargo]

Any other issues improved?

[vague smelt]

Idk but I think I know what is propably causing this

because I have custom shader for vision (Game only renders where I look), maybe it does something wrong in this custom code

because it looks like on default lit 2d material it doesn't happens

[modest cargo]

That very heavily implicates your custom shader

Always helpful to start with those kind of details
We have no way of knowing what custom assets you have that could be causing issues

[vague smelt]

I can send the code of it

btw it is not mine but from someone's vid I think

It has 2 materials vision entity and vision background

And it just changes the last blending style to it

[modest cargo]

Is it intended to be used with Unity's 2D lighting? Or is the lighting custom too?

[vague smelt]

unity's

it is copied lit 2d shader and added extra things to it

https://www.youtube.com/watch?v=XWMPEE8O05c It is his shader

Okay nevermind somehow fixed it by adding normal map to wall texture

[spring wharf]

Does anyone know what I am doing wrong?

Hey, as soon as I enter animation mode, changing the position/rotation of my sprites doesn't work anymore, see the gif:

[spring wharf]

Here you see that afterwards in fact the transform is successfully animated, just the sprite is not updated

[short osprey]

Hey people! I am having a silly issue. I am working with URP 2D and set up many polygon colliders configured as triggers on my scene. I found out that the reference sprites were off position by some little amount, so I moved them back where they are supposed to be, but now of course all the triggers, owned by an other game object, are off position by that same amount. I saw that i can offset them, but I would like to move them all in the right position while keeping the offset at zero. Is there a way to achieve that?

I mean, other than rebuilding all of them from scratch or moving them point by point to the new position...?

[modest cargo]

If you don't want to rebuild them manually I think the options are

1. Copy the collider to a separate child gameobject and move that instead, a bit hacky though
2. Remove the polygon collider and add it again, which should generate a new one based on the sprite's physics shape

[short osprey]

I think option one is the one for me then, my little squared brain can't accept to have such offset though. I might have to offset the triggers, then write an editor script to add the offset to every point and then set the offset to zero...

A little uncomfortable, but it will be useful in the future I guess

Thanks

[modest cargo]

I stress again that if your sprites have physics shapes from the sprite editor, a newly added polygon collider will use that physics shape
If the result is valid, you won't need to do any manual work

[short osprey]

They are triggers manually placed on the scene, not physics colliders, unfortunately

[modest cargo]

Triggers and colliders are created the same way

But if they're not based on sprites I think it's not an option anyhow

[short osprey]

yes, but they are not shaped around sprites, they are manually shaped

[short osprey]

Yes they are triggers like "when the player moves here make that happen"

it's a bit hard to describe the scene structure, but the key is that these triggers are not shaped around sprites

Thanks indeed, the idea itself was good if that was the case

[modest cargo]

It gave rise to the idea to create and store polygon colliders polygon colliders as sprites for more flexible iteration, in case I anticipate a similar situation ^^

[analog widget]

is it possible to generate shadows from a tilemap collider?

2d shadows are kinda really annoying lmao

[normal river]

How do I trim sprites without changing the center pivot assigned from a grid slice?

[modest cargo]

I guess you could change just the slice bounds
If that doesn't work, could try defining a custom outline

Or hot swap the sprite sheet with cropped versions if all else fails

[normal river]

i exported so that my rotating sprite stays around a 64x64 grid, trimming makes the pivot of the sprite the center of the sprite area and not it's original grid slices

[modest cargo]

Try custom outline next
I don't see the point of cropping just the slice bounds anyhow, unless you need the sprite sheet space for something else

Well, I think the more meaningful response may be why do you need to crop it in the first place exactly

[normal river]

i was under the impression the sprite bounds determined the hitbox

[modest cargo]

"hitbox"?

[normal river]

for collisions

[modest cargo]

"Physics shape" in the sprite editor defines the default shape of a polygon collider component assigned to the same gameobject

If your sprite shape is "tight" it should be perfectly cropped to begin with

[normal river]

oooh

very helpful thank you!

just saved me a ton of time lol

[modest cargo]

Other than that you'll be using primitive collider components which I think also take their initial size from the physics shape, but you'll often customize those anyhow

Or create generic variants

@normal river One more thing to note is that no type of collider adjusts to animation automatically
The shape is only considered at the time of adding the component

[normal river]

so i got to change the outline tolerance to 1 for each of these and generate each manually?

or will this work:

[modest cargo]

You probably don't need to
That's the "custom" physics shape
With tight type sprites I believe it'll generate one with default settings even without doing anything manually

[normal river]

ah ok

[modest cargo]

That's the skinning editor, not related to physics I think

But again since the polygon collider doesn't respond to changes like animation, I expect you may want to use a generic primitive collider instead

At least what I would do is build colliders from boxes and circles in the shape that matches well enough all animations, and when they don't, keyframe the colliders to match

Polygon colliders can also be keyframed iirc but it's kinda tedious and pointless

Players often prefer predictable colliders over precise ones

[normal river]

https://gyazo.com/69a9e09ab28adab25033fd8a12b87b1a

why is this happening during my empty frames?

[solemn latch]

Define 'this' in this context?

[normal river]

The mesh box maximizes on frames without pixels, if I’m to use this as a hit box it’s gonna cause a ton of problems

[modest cargo]

Is that the physics shape or the sprite outline?
In either case I suppose you could just disable the whole sprite renderer (or just the collider) on empty frames

Rather than displaying "empty frames"

[true niche]

Guys i'm using multiple tilesets to make a layered map, do you know why when i zoom in and out some layers disappear and reappear?

[modest cargo]

How are you sorting their draw order?

[true niche]

i haven't done anything, just created a new tilemap when i needed another layer

then the order is by the actual order of the objects in the hierarchy

[modest cargo]

Hierarchy order is not used for sorting sprites, nor for tilemaps under grid component as far as I know
https://docs.unity3d.com/Manual/2DSorting.html
I recommend you spearate them by Z position or sorting layer
If they have the exact same 2D sort order, the editor will basically pick their order at random

[still tendon]

I sent this a few days ago and I'm sorry to repost it but it's probably something stupid that would be more equate here

[modest cargo]

I would assume that the sprite is too small relative to camera size, and the view on the left is zoomed in using game window Scale

It's also possible that there's problems with the import settings, but it's hard to give a precise diagnosis on an example that's had its context cropped out

[still tendon]

It's a 16x16 tilemap

I just stared building the world and in the game tab it like not rendering as if it was low res pixel based

I can send a more detailed screenshot after school

[elfin sandal]

did u use pixel perfect component

[still tendon]

The what?

I assume that will help me

[modest cargo]

It likely might, but it depends on what the issue is precisely

[still tendon]

i jsut got home so now im loading up unity

ill send a screenshot of my project in a min

here it is

here is the camera setings if that helps

okay so it was jsut the fact the camera was way to big compared to the sence lol

i made it big being that i was gunna make a huge world map

[modest cargo]

Resolution, camera ortho size (and game window zoom) are very important for how pixel art is displayed

[still tendon]

i guess i jsut expand it as the project gets bigger?

[modest cargo]

Ultimately you cannot display more than one sprite pixel in one screen pixel, or distortion will ensue

[still tendon]

im sorry but i have no clue what you mean

[modest cargo]

If your monitor is 2 pixels by 2 pixels, how are you going to display a sprite that's 3 pixels by 3 pixels without loss of data

[still tendon]

oh wait do you mean its try to expand it but because its one pixel thats not posible to - yeah i jsut realized it sometimes im a bit slow

[modest cargo]

It's a very common mistake ^^

To render pixel art perfectly, you'd have to make sure that each sprite pixel matches each screen pixel precisely, in position, rotation and size

Basically it means that sprite size / pixels per unit value, ortho camera size and screen resolution must all have a very specific ratio

[still tendon]

so jsut expand cam as i grow the world tilemap

[modest cargo]

No
The camera size must match the resolution of your sprites, regardless of the size of your level

You can expand it to zoom out, but then the pixels get mushed together again

[still tendon]

so make it 16 being that im makeing this is 16x

but then jsut move the camera to show difrent parts?

[modest cargo]

That's the right direction, but required math is much more complicated

Realistically you have two options
Learn to use the pixel perfect component
or give up anything being pixel perfect and just eyeball it so that it's good enough

It's not enough to get the PPU values, ortho size and display resolution to the correct ratio, you'll also have to restrict sprite positions to pixel increments
The pixel perfect camera component does all that and more

[still tendon]

id like to eliminate any blur and warping so i guess lean the pixel perfect thing

[modest cargo]

https://docs.unity3d.com/Packages/com.unity.2d.pixel-perfect@5.0/manual/index.html
Here's the manual that explains how to set up the component in full detail

[true niche]

yeah that worked, thanks

[solemn latch]

Third option is to use something like smoothpixels.

[modest cargo]

I always forget that it's an option
Probably passable enough for most, though I think it's important to understand what causes the problem in the first place

[solemn latch]

The problem is that Unity wasn't designed with pixel art in mind =p

Which is pretty reasonable since back then there were better options for that kinda thing.

[sharp apex]

I hope Unity upgrades its Tilemap package so we have a better implementation of Tile Rules, like the one from Tiled/ASEsprite featured in this video:
https://www.youtube.com/watch?v=TL_JZIuydas

[languid tendon]

quick question why is it I can't activate the snap tool when working in 2d unity and how do I fix it

[solemn latch]

Can't you just use aseprite and import it into unity then?

[modest cargo]

You can read Tiled tilemaps in Unity, but it won't respond to runtime changes naturally

[modest cargo]

Grid snapping is available only when your tool rotation is in world space

Vertex snapping doesn't care

I'm having an issue with a cursor not following my mouse fully correctly and jittering loads

The camera sets its position to the physical player rigidbody position

The cursor sets its position to the Input.mousePostion

This happens nomatter what update / fixed update / late update I put either of these in

I'm unsure if this is the correct place but I believe it's to do with the pixel perfect camera im using

[worn zealot]

That spider is adorable. And yeah, it is probably due to pixel perfect camera if changing when in the order you are executing.

[river iron]

Lil bro says hi

But yeah if it is a pixel perfect camera issue I don't know if it's one I can solve

[modest cargo]

Well, how are you moving the cursor exactly?

It seems to lag behind as it is

[river iron]

Sprite renderer on a gameobject i set the position of

[modest cargo]

"set" how
to what

[river iron]

So literally just transform.position = mouse position

Using Camera.main.ScreenToWorld

Sorry not at pc rn otherwise I'd ss the code

but yeah I've stripped it back to just bare minimum of setting position of the cursor to the mouse

No lerping

the cursor is a parent object with 4 children corner objects if that matters

But the children do not move

[modest cargo]

Hmm, parenting is the most robust way to attach things together
I would try as a test to disable the cursor script and just parent the cursor to the camera, see if it still seems to jitter

If it still does, the script isn't at fault

If it doesn't, I'd try to enable the cursor script and make sure the moving happens in LateUpdate

[river iron]

Right so parent it first to see

Then I can still set position

it shouldn't affect the script itself actually just parenting so no reason not to yeah good plan

We'll see but I'm not hopeful will check in a bit

[river iron]

hm your plan was a good plan

just having the cursor parented makes it move as expected (no jitter)

and then enabling it following the mouse makes it jitter even if the mouse isnt moving

its almost as if Camera.main.ScreenToWorldPoint(Input.mousePosition) isnt being updated properly even tho its in LateUpdate

and the jitter only happens in the game view with the PixelPerfect camera active
really starting to feel like a Pixel Perfect Camera issue

[elfin sandal]

Probably floating point errors

Youd need to tell your script to move in pixel increments

Or just have the cursor be part of the ui canvas instead of a world object

[rain hornet]

is there a better way to import tiles into a rule tile? i am using 2d extras in unity to create rule tiles, however manually selecting tiles from the expanded .png is very annoying and also very hard to see since my sprites are 16x16

[modest cargo]

I find that you can add multiple sprites at once, but only if the rule tile list is empty at that point

for whatever reason

[ruby hamlet]

Hi can someone help me
this video I was following on youtube said to add a sorting layer and call it Background and move it above the default layer and move all my background sprites there
but this happens when I do that

but if I move my sorting layers back to default it all shows up

[modest cargo]

The most likely explanation is that the objects aren't on the correct sorting layers
Anyway, sorting layers are just one type of 2D depth sorting
I prefer to use Z depth instead, but it's good to be aware of the options
https://docs.unity3d.com/Manual/2DSorting.html

[rain hornet]

yes, right now I use shift and ctrl click to select multiple tiles that I will have to add

While This Helps a lot I don't know why I cant add multiple sprites like this when the list has something.

this is especially annoying since in a [serialized] list field I can add multiple items at once but not in this one

also is there a way to view the expanded .png or attest the sliced sprites in an organized manner like how importing the sprits to a tile map pallet allows you to.

[plain girder]

Has anyone got a clue as to why my background likes to diseappear on my scene view and not appear on my Game view?

[river iron]

It needs to be a physical object rather than UI for specific reasons

Even if I round the position to the pp camera pixels it does it

Floating point errors doesn't seem to make sense as it's such a big jitter

hello, how can I change the render order of my tile maps?

Every time I finish editing my tiles the way I want them, which is to have the wall tiles over the floor tiles, they reverse and the floor tiles render over the wall tiles

[modest cargo]

Tilemaps follow the same sorting rules as all other 2D renderers
https://docs.unity3d.com/Manual/2DSorting.html
But if you're using isometric tilemaps you need to do some extra to define tile sorting by their virtual height
https://docs.unity3d.com/2021.3/Documentation/Manual/Tilemap-Isometric-RenderModes.html

[upbeat edge]

Id like to add empty spots in this ruletile to cover my levels randomly with grass in one fell swoop with the bucket / area paint tool. What's the best way to add blanks spaces here? Just blank game objects, or should I make a transparent tile?

I did initially try adding empty spots in the Size property, but it seemed to really skew the randomness.

Yeah actually, I think i needed to just add a whole bunch of empty ones to the middle, instead of the sides. And an equal amount on either side at that.

[upbeat berry]

I assume these are common questions; so I'm hoping there are common answers. I'm working with an isometric tilemap and am having sprite layering issues. Specifically, I'm struggling with where to put the pivot point on wall sprites.

1. This first issue I'm having is that the pivot is used to position the sprite on the tile relative to the tile anchor. This means the pivot has two responsibilities; one to order and one to place, and they are often in conflict.

2. The second issue I'm having is where to place the pivot for objects that are rectangular as seen in the image. If I place the pivot on the lowest traversable point behind the wall, then sprite layering works when the character is behind. But if the sprite is at the highest traversable position or just simply above the pivot point, but in front of the wall.. The character will appear erroneously behind the wall.

It seems like this just may be a limitation of the engine and I need to adjust my asset creation process to ensure that walls aren't long enough to have the desired pivot be behind and in front of the wall. I just wanted to make sure there isn't a tool or feature I'm overlooking that solves this problem.

It appears the solution to both issues would be to ensure that walls take up the entirety of the tile...

Any thoughts would be appreciated. Thanks!

[hard nimbus]

I keep getting these weird lines between my tiles

[modest cargo]

If you're not using pixel perfect rendering, tilemaps may show adjacent pixels from the tiles' sprite sheet
If you don't need pixel perfectness and only need to fix that, you can add padding to your sprite sheets between each sprite in an external image editor, or generate a sprite atlas which also has the option to add padding

[hard nimbus]

how do I use the sprite atlas in a tilemap?

or rather, I already tried pixel perfect camera but it didn't seem to work well (camera randomly jumps between different zooom factors, laggy cam movement. I am using cinemachine but I did also add the pixel perfect cinemachine effect which didn't do much

[modest cargo]

No different than using it for other renderers
Though I don't know the exact details, I assume it just updates all renderers that reference sprites to use their corresponding positions on the atlas rather than in sprite assets

[hard nimbus]

alright, pixel perfect does seem to work now

for some reason

but it makes my camera zoom in more

[modest cargo]

Pixel Perfect Camera requires you to work with very specific settings or it may appear glitchy
It's a whole workflow designed to emulate low resolution screens and render pixelated graphics accurately
I wouldn't usually recommend it if your goal is not to have a pixelated style

[hard nimbus]

I mean I want to make a game with mainly pixel art style

but I don't want the movement or camera move pixelated

so for the sprite atlas (sry for switching all the time but I think that'd be the best solution)

I packed every spritesheet into it

and then? is it automatically used for all the tiles? bc it doesn't seem to do anything

[modest cargo]

There's various ways to use the pixel perfect component to control how exactly the sprites are rendered relative to real screen pixels
But it's a pretty complex tool and easy to get wrong unless you know precisely how to use it

[modest cargo]

I'm not totally sure since I haven't used it for this purpose

[hard nimbus]

ah setting padding to 8 seemed to fix it

[modest cargo]

If you can find this menu "always enabled" would at least make sure it runs

[hard nimbus]

but now I'm getting this error

everytime I playtest

[modest cargo]

Vague editor errors may be annoying but are rarely concerning unless they visibly break something

[hard nimbus]

yeah truer

but it only happens since I changed the padding

weird

[modest cargo]

It's as cryptic as it is generic
With luck it'll stop occuring on its own, maybe on scene change or editor restart or something

[hard nimbus]

alright thanks for the help!

[arctic harness]

hi im new to unity, can anyone suggest a method to learn unity 2d without following tutorials blindly(i have some coding experience in python and I know the basic fundamentals of programing)

[lost flint]

https://learn.unity.com/ is the best way

[arctic harness]

what do u think i should start with?

[lost flint]

Because it contains everything you need to start up and has been validated by people with experience.

[arctic harness]

no, i meant which course

My bad, I read your message a bit too fast.

[arctic harness]

nah its ok

When working with tilemap tiles, movement causes these weird lines to appear, both in the editor and in the finished exported product. Does anyone know what's causing this?

using 2d tilemap extras

[stray whale]

Fixed!

Anyone know a good place to get grass/dirt/sand/etc. textures that span large areas? I'm looking for seamless textures that are 1024x1024 - 4096x4096 but represent 50-100 square meters of terrain so that the repetitive nature of textures is not noticeable. I'm willing to purchase the textures, but free ones that I can use for prototyping would be fine also. Everything I'm finding is mostly designed to be repeated every 1-3 square meters and that just doesn't look right.

[modest cargo]

It's not usually the first option to try eliminate repetition with just one perfect texture
Usually you see the patterns broken up by blending between multiple textures and terrain types as well as with detail meshes, that's how you see it done in 90% of games
In case of monotonous terrain material it's common to combine a low-resolution texture with "detail mapping", so the low res texture gives color variance to the detail map which is only seen so close you won't see the repeat
Even beyond that there are shaders that can break up the repetition, though those are more expensive to render
https://github.com/UnityLabs/procedural-stochastic-texturing

In 2D the concepts remain the same but implementation may be different

[tropic jungle]

Thanks ... While I'm sure I'm going against the grain (which is not a good thing), I wrote a custom shader with DOTS Instancing that uses a 2D Texture Array of biome textures and blends between them based on the biome of each "tile". I hope I didn't shoot myself in the foot too much. I like how games like RimWorld handled terrain that looks natural over larger areas (see screenshot). I'm able to achieve that ... but I don't have textures I like.

What mine looks like so far (the scale is very wrong right now, those dots are trees when you zoom in while the grass texture is spread too wide for what the texture is):

[modest cargo]

Thanks While I m sure I m going against

[dim wraith]

Is it fairly normal for a scene to have multiple tilemaps on different layers to show depth, or is there another way to do this?

[solemn latch]

So add more than one texture per biome and mix them using noise or something?

[tropic jungle]

I might explore other options with my shader later, I found a texture I'm a bit more happy with for now. I want something more realistic in the future, but this is at least moving in the direction I want:

[hidden swan]

tileset building is pain

[opaque snow]

I want to make my sprite twice as wide, is there anyway I can do that in the Unity sprite editor?

My sprite editor has some options greyed out as well and I don't know why. Would this help?

[elfin sandal]

Either change the scale intransform settings or the pixels per unit when selecting the sprite file

[modest cargo]

I can see the seams, but looks pretty good!
You can still have those leafy details you had originally if you want, just make them appropriately small enough and repeat them with variation so the eye can't catch what parts "really" repeat
Like those wavy patterns in the sand example were repeated

[modest cargo]

They're probably greyed out because a single-type sprite can have only one position within the sheet and only one name

I believe the position in the sprite editor signifies where individual slices are in the sheet, but only multiple type sprites have more than one slice

why does my tile rule look weird am i doing something wrong

this is the way i actually want it to look like

[tropic jungle]

I didn't really love the leafy pattern of the grass before, that was just proof of concept. I want an even more realistic style than this in the future, but this is at least in the right direction for now while I focus on other systems.

[opaque snow]

This is a png I want to import as an asset into Unity.

When I try, the sprite imports like this:

This pink doesn't appear in the sprite editor and I have no idea how to remove it. Any ideas?

[modest cargo]

This usually happens when you have a sprite renderer not using the sprite material

[opaque snow]

My material is default-line

Also, other sprites are unaffected:

I haven't tested out all of my sprites as I don't want to have to format all of them, then remake them, then reformat

[opaque snow]

What else could it be?

[modest cargo]

Not sure but your sprite renderers aren't using the sprite material, like I expected
Isn't the obvious first solution to try to swap to a sprite material

[opaque snow]

Thank you for the help. I though Default-Line was the material in question by I found a new one
