Final take for the #boids ! Testing a flock of 16k boids, entirely computed in GPU. No more CPU boilerplate, thx to the precious help of Jason Knight (from X). The code is available at @thegodotbarn.com . #gamedev #godot #glsl

Here's a short thread of my code for the Pinni distortion effect, because everyone always asks me about it. This will work for *any* game engine that uses shaders (e.g. Unity, Godot). Without further ado, 2D displacement maps 🧵: #gamedev #tutorial #shader #glsl
