Example of an old but super cool system: https://www.youtube.com/watch?v=JK1aV_mzH3A

So what I imagine is a component called ParticleSpawner or something like this. This component has a bunch of settings similar to Godots system. I would at least like the following:

• texture
• life_time (float)
• speed & direction (vec3)
• scale (float)
• emitting (bool)

Having more options would be cooler of course!

Than we have a ParticleRenderingSystem that runs after the TerrainRenderingSystem and WaterRenderingSystem with alpha blending enabled. This basically get's every entity with a Transformation object and a ParticleSpawner that is emitting particles and renders them.

Some notes / thoughts:

I know that ThinMatrix has some videos that go into this direction.

I would basically think that we have one VBO that has a bunch of squares consisting out of two triangles. Each square has an particle ID from 0 to n. The rendering reuses this VBO for all particles. It just changes the used texture and origin point using uniforms. Note that we should rotate the squares them self to be orientated to the camera. This definitely needs some uniform magic 😅 .

Tasks

• Load textures
• Create particle component
• Alpha blending
• Maybe: Motion along calculated smooth curves in shaders?

• Diffuse lighting
• Specular lighting
• multiple lights
• Light fading effect
