EdgeBehavior

Defines how particles behave when they reach the boundary of the emitter's composable.

Types

data class Bounce(val damping: Float = 0.7f) : EdgeBehavior

Particles bounce off edges, reversing their velocity component perpendicular to the boundary.

Particles pass through edges freely and disappear off-screen. This is the default behavior.

Particles stop at the edge and remain there for the rest of their lifespan. Velocity is zeroed on contact with the boundary.

Particles that exit one edge reappear on the opposite edge, maintaining their velocity.
