Tutorial for Bad Apple but it's a 172800 Entities in Unity ECS!
What am I trying to achieve in the Bad Apple with Unity ECS video?
- I want to show you the capabilities of ECS with Jobs and Burst, where in real time, every frame, we can modify 172800 entities materials while maintaining 170-180 FPS (even 190 FPS without recording)! And there is still the potential of rendering on the graphics card, so the performance can still be increased!
How did I do it?
- First, the ISystem - BadAppleSpawnerSystem - spawns 172800 entities (quads) based on the size of the RenderTexture (width x height).
- Then I bake the RenderTexture as Managed ComponentData and read pixels from the 2D texture (async, 640x480 = 172800 pixels) from SystemBase. I execute several jobs (parallel) in which I write the color as a float4 value into BadAppleVisualizationColorComponentData. Of course, all of this is annotated with the [BurstCompile] attribute.
- The value is read by the shader which has the Shader Declaration parameter set to: "Hybrid per instance" (required to work!).
