ParticleSimulation (Mibo.Raylib)

ParticleSimulation Module

Namespace: Mibo.Elmish.Graphics2D.Lighting
Assembly: Mibo.Raylib.dll

Helpers for particle simulation. Called in the user's update function.

These operate on the simulation state (velocity, lifetime, etc.), not the render snapshot. After simulation, map your sim state to Particle2D render snapshots for the view function.

Function or value Description

Function or value	Description
`fadeAndCompact particles count fadeSpeed dt` Full Usage: `fadeAndCompact particles count fadeSpeed dt` Parameters: particles : `Particle2D[]` - The particle render snapshot array. Mutated in place. count : `byref<int>` - Current active count. Updated to reflect compacted array. fadeSpeed : `float32` - Alpha reduction per second. 255.0f means a particle fades completely in 1 second. dt : `float32` - Delta time in seconds. Modifiers: inline	Fades particles by reducing alpha and compacts the dead ones out of the array. Particles with alpha <= 0 are removed. Returns the new count via the byref parameter. Call this in your Tick handler after updating positions/velocities. particles : `Particle2D[]` The particle render snapshot array. Mutated in place. count : `byref<int>` Current active count.
