Syntax
class UParticleModuleCollisionGPU : public UParticleModuleCollisionBase
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
TEnumAsByte< EParticleCollisionMode::Type > | CollisionMode | |
 |
float | Friction | Friction applied to all particles during a collision or while moving along a surface. |
 |
float | RadiusBias | Bias applied to the collision radius. |
 |
float | RadiusScale | Scale applied to the size of the particle to obtain the collision radius. |
 |
float | RandomDistribution | Controls bouncing particles distribution (1 = uniform distribution; 2 = squared distribution). |
 |
float | RandomSpread | Controls how wide the bouncing particles are distributed (0 = disabled). |
 |
FRawDistributionFloat | Resilience | Dampens the velocity of a particle in the direction normal to the collision plane. |
 |
FRawDistributionFloat | ResilienceScaleOverLife | Modulates the resilience of the particle over its lifetime. |
 |
TEnumAsByte< EParticleCollisionResponse::Type > | Response | How particles respond to a collision event. |
