Specify how particle speeds are mapped to the animation frames.

If a particle is travelling slower than the minimum speed, it uses the first frame. If a particle is travelling faster than the maximum speed, then it uses the final frame. For all other speeds, the particle chooses a frame based on how far between the minimum and maximum value its speed is.

[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { private ParticleSystem ps;

void Start() { ps = GetComponent<ParticleSystem>();

var textureSheetAnimation = ps.textureSheetAnimation; textureSheetAnimation.enabled = true; textureSheetAnimation.speedRange = new Vector2(0.9f, 5.0f); } }
