Description

Script interface for the CollisionMmodule of a Particle System.

Properties

bounceHow much force is applied to each particle after a collision.
bounceMultiplierA multiplier for ParticleSystem.CollisionModule.bounce.
colliderForceHow much force is applied to a Collider when hit by particles from this Particle System.
collidesWithControl which Layers this Particle System collides with.
dampenHow much speed does each particle lose after a collision.
dampenMultiplierChange the dampen multiplier.
enabledSpecifies whether the CollisionModule is enabled or disabled.
enableDynamicCollidersAllow particles to collide with dynamic colliders when using world collision mode.
lifetimeLossHow much a collision reduces a particle's lifetime.
lifetimeLossMultiplierChange the lifetime loss multiplier.
maxCollisionShapesThe maximum number of collision shapes Unity considers for particle collisions. It ignores excess shapes. Terrains take priority.
maxKillSpeedKill particles whose speed goes above this threshold, after a collision.
maxPlaneCountThe maximum number of planes it is possible to set as colliders.
minKillSpeedKill particles whose speed falls below this threshold, after a collision.
modeChoose between 2D and 3D world collisions.
multiplyColliderForceByCollisionAngleSpecifies whether the physics system considers the collision angle when it applies forces from particles to Colliders.
multiplyColliderForceByParticleSizeSpecifies whether the physics system considers particle sizes when it applies forces to Colliders.
multiplyColliderForceByParticleSpeedSpecifies whether the physics system considers particle speeds when it applies forces to Colliders.
qualitySpecifies the accuracy of particle collisions against colliders in the Scene.
radiusScaleA multiplier that Unity applies to the size of each particle before collisions are processed.
sendCollisionMessagesSend collision callback messages.
typeThe type of particle collision to perform.
voxelSizeSize of voxels in the collision cache.
