I’m gonna give 10 random people that repost this and follow me $25,000 for fun (the $250,000 my X video made)

I’ll pick the winners in 72 hours

I completed my first game jam yesterday🎉, this was an unforgettable experience. Gam Jam was supposed to last 3 days, but we started only in the middle and tried really hard to create something decent in that short timespan and I think we did! 😄🎮

I fiddled around with #Roslyn Source Generators for #Unity a little bit.
I wrote a simple generator that generates Reactive Properties, you can imagine something like that might be useful for building MVVM for example

Got a cool twirl effect while messing around with a 2d rotation matrix, btw matrix construction node is really handy.

Using the Temporal Offset Map, we can offset the appearance of parts of a texture, which is really useful!

[PixelPerfect @alex_rogatch]

Recently, while learning how to create a rain shader, I discovered a thing called Temporal Offset Map.
Thank you so much @BenCloward, your tutorials have been an invaluable resource and I'm learning a lot!

Started learning about graphs for one of the projects I'm working on.

Recently, I needed an object pool that could differentiate between different types of objects. Unfortunately, Unity's Pool doesn't support that, so I created one myself.
Features
- Can differentiate between objects
- Uses HashSet to prevent duplicates

An interesting effect I made while learning about compute shaders, how does it look like?

@unitygames @minionsart Been learning about QuadTrees and created this simple QuadTree visualization

[PixelPerfect @alex_rogatch]

I'm planning on doing procedural world generation in the future, so I figured that I might as well start with QuadTree for terrain partitioning.

[PixelPerfect @alex_rogatch]

Here is a simple visualization I made while learning about QuadTrees. It's a procedurally generated mesh with a wireframe shader.
QuadTrees are widely used in #gamedev and can help speed up collision detection and reduce rendering overhead.

Hello, I present you with the Human Shader, a project where anybody can participate and help create the first ever human-brain-only powered shader and mathematical image! Please join us and be part of history!

[PixelPerfect @alex_rogatch]

I don't have much to share, but I did a simple textured quad, and I really like it so far. All the things I learned working with shaders in Unity and didn't fully understand, all of this starts to fall into place.

I wanted to try to work with OpenGL or DirectX for quite some time, but almost all learning resources are using C++, which I don't really know. So, I was really excited to find https://t.co/iCixpKolys, a library that provides low-level bindings for OpenGL and other APIs.

[PixelPerfect @alex_rogatch]

So, the performance so far is:
1 million cells using instancing ~700 ms
1 million cells using instancing indirect and jobs ~16 ms
but when a new generation is created there are spikes to around 80 ms
Btw, I uploaded the project on GitHub: https://t.co/111BbKOm6g

I wanted to learn about optimization and profiling in #Unity for some time already and came up with a great project to learn with. So, here I'm creating Conway's Game Of Life on as large scale as I can manage to optimize. #GameDev #Optimization #GameOfLife

[PixelPerfect @alex_rogatch]

Two more optimizations I made:
1) Move the game algorithm to jobs, it resulted in a significant performance boost.
2) Switched to using Graphics.RenderMeshIndirect, which didn't make any performance difference, since the rendering was already fast.

[PixelPerfect @alex_rogatch]

My takeaway from that is it's okay to use LINQ where performance isn't a major concern, like methods that won't get called frequently. But when something is frequently called, LINQ should be avoided, because of the allocations it produces on every call.

[PixelPerfect @alex_rogatch]

A little note about LINQ's performance. This LINQ code was 2 times slower than for loop, allocating garbage every call. Previously, I thought that the only thing I need to care for using LINQ is avoiding closures. Turns out, that's not all. #Unity #LINQ #GameDev #Optimization
