Raycast Behavior
This behavior uses raycasts to detect collisions along the trajectory of a particle. If a particle would collide with geometry, the behavior can either adjust the its velocity, or terminate the particle early, potentially raising an event, which could in turn lead to other effects or being spawned.
Reaction: Specifies how the particle should react to a collision.
- Bounce: The particle's velocity will be adjusted such that it bounces off the hit surface.
- Die: The particle will be killed early.
- Stop: The particle's current velocity will be set to zero, thus stopping it in its tracks. If other position affecting behaviors are active, for example the gravity behavior, it will start moving again, but without its previous momentum.
BounceFactor: How much of the current speed should be preserved after the bounce.
CollisionLayer: The physics collision layer to use. Affects with which geometry the particle will collide and which it will pass through.
OnCollideEvent: An optional name of an event to raise. If set, other effects or prefabs can be spawned at the location of impact.
