Help implementing sprites for UI
I wanted to use sprite animations on UI for a turn based RPG I am making in Unity where they popup from behind the menus Akin to Mother 3. I want those characters to use many different animations for getting hurt or attacking. However, is there any way to do this without needing to make the size of the canvas for all characters match? Essentially, I am asking for a sprite renderer but transformed to screen coordinates instead of world coordinates.

What am I doing wrong here?
I'm trying to change a button's color when it's clicked, but when I click it it becomes invisible. I can only see the "BOUGHT" text. (I used an online RGBA color picker to get my values)
private void Update()
{
clickCount.text = clicks.ToString();
clickCountShop.text = clicks + " clicks";
if (doubleClickerBought == false)
{
doubleClickerBuyText.text = "BUY";
}
else
{
ColorBlock colorBlockGray = new ColorBlock();
colorBlockGray.normalColor = new Color(141, 139, 140, 0.8f);
doubleClickerBuyText.text = "BOUGHT";
doubleClickerButton.enabled = false;
doubleClickerButton.colors = colorBlockGray;
}
}

Someone asked how we render outlines in our game, so here's a detailed breakdown
This is my team's game, Whisker Squadron: Survivor. We're quite proud of the rendering in the game!Someone recently asked how we draw the interior lines so cleanly, so I thought I'd write up a detailed breakdown here. A lot of what we're doing is pretty standard, but we have some "special sauce" in here too.
Hope it helps!
Whisker Squadron: Survivor
A brief overview:
We use a post-process effect that started out with the excellent Roystan tutorial.
We then modified this to give our artists more control using a technique we call "Alpha cues".Our game uses the old-school legacy rendering pipeline with forward rendering.
The Basics
First, here's what the game looks like without any outlines:
No Outlines
The post process shader makes use of the standard "depth buffer", which looks like this:
Depth Buffer
The first part of the PP effect simply looks at a cross-section of pixels around each point on the screen, and a threshold value determines whether a jump in depth counts as an edge:
Depth Buffer Detail
(Technically speaking, we use a "roberts cross" algorithm to do this pixel examination, see references below).
Here's what it looks like with *just* those depth-based lines:
Depth-Lines only
Next up: Interior edges. Our rendering system does a custom pass where it renders "normals" into a buffer:
Screen normals
And then the post process effect does a similar calculation where it determines how much changes from one pixel to the next using a cross pattern.Here's the result of the scene with Depth + Normals:
Depth+ Normals
And here's a closeup of an example of these normal edges:
Normal Edges
Incidentally - since we can independently detect depth-based edges and normal-based edges, we expose different settings for line thickness for each of these. Exterior edges have heavier lines.
​
The Secret Sauce: Alpha-based lines
So far, the techniques we've used are pretty standard. But we wanted a way to add "greebles" and little hand-drawn details on our objects.
To accomplish this, we modified our object shader to render the alpha channel as simple greyscale.This is not visible to the player, but here's what's happening in the alpha channel behind the scenes:
Alpha output from object shaders
This allows our artists to make "greeble" textures and apply them to objects however she likes:
Greeble textures with alpha output

Here's another shot showing with/without those "alpha" lines.
​
Fixing Issues and Tuning
If we just rendered lines everywhere naively, the distant objects would become very overwhelmed by the lines, since they have a constant thickness. So we have 3 different "blend range" parameters - one for depth-lines, one for normal-lines, and one for
We just released our multiplayer roguelike, Dungeon Survivors! Thanks to everyone here for the feedback and support. We have made tons of changes to the game based off everyone's feedback from the demo!

Help with Visual Studio coloring (I am completely new)
Hi guys, I've been just following a tutorial I found online and everything has been working just fine, but for some reason, some color dissappeared from Visual Studio and its bothering me. Things like the Time from Time.deltatime used to be a greenish blue, but now its just white. Any ideas of what might have caused this?

Switched from HDRP to URP at a worse framerate
Hello fellow game devs
I've been developing Plunder for quite some time now. I started using HDRP and while it looked amazing it didn't give me the flexibility and framerate I wanted. Although It peaked at 100 FPS on my GTX 1080, I thought the simplicity of my models would allow me much more.
I decided 4 months ago to switch to URP, with targeting as many hardware specs as possible in mind. You know, it's designed for mobile so it should be easy to render on a desktop, right?
My builds are only getting 60FPS.
Standalone dev build, standalone profiler, 25ms CPU usage
While I have a good grasp on how to read the profiler, or so I think, I notice most of the framerate is lost due to rendering.
The frame debugger shows the following:

I first thought it had anything to do with vertice amount and batches, but all of my scene objects are marked as static and properly batched:

Proof an empty scene still has bad FPS:

I have enabled URP static batching, GPU instancing on materials. One directional light with dynamic shadows and a dozen point lights with no shadow casting.

400K tris from ocean being rendered, should there not be more FPS on an i9 + 1080?

Why does this one face on my model not light up correctly?
https://redd.it/1ayaymz
@r_Unity3D
alpha-lines.
Additionally, alpha lines blend out closer to the camera the lower the contrast is. So if the greeble textures have an area of light grey, they will blend out nearer the camera than areas that have a black area. This makes it possible to add finer details that can only be seen up close. The downside is that it's not super intuitive, so it took our artists awhile to figure out how to use it effectively.
​
Distance fade
That's about it! There are some other technical challenges, which the excellent Roystan tutorial (referenced below) mostly addresses.
​
Let me know if this is helpful or if you've got any questions! The code is a bit of hacky mess so I'm hesitant to share it but if you ask reeeeal nice I might ;)
Areas for Improvement
1. We could probably save a whole draw pass by using Unity's depth+normals texture rather than rendering our own normals texture. This would also mean less texture sampling.
2. There's not currently a way to have different line colors on different objects. It'd be nice to have!

I've been with this problem for a while now. If your enter to the link below you'll see a short video where it's shown how the player's ship is moving odd, as if it was stuck. I think the issue lies in the code. I'll put it here below:

"The Unity Tutorial for Complete Beginners" pipe problem
I am working through the Game Maker's Toolkit video that creates a Flappy Bird knockoff, and I'm having trouble with the location of the pipes. Although I have "heightOffset = 10" per his code, the openings between the pipes are mostly out of the camera window. I even copy/pasted his code, and the result was the same. What am I missing? Could I have a setting within Unity wrong?
