Syntax
class URadialForceComponent : public USceneComponent
Remarks
Used to emit a radial force or impulse that can affect physics objects and or destructible objects.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
uint32: 1 | bIgnoreOwningActor | If true, do not apply force/impulse to any physics objects that are part of the Actor that owns this component. |
 |
uint32: 1 | bImpulseVelChange | If true, the impulse will ignore mass of objects and will always result in a fixed velocity change |
 |
FCollisionObjectQueryParams | CollisionObjectQueryParams | Cached object query params derived from ObjectTypesToAffect |
 |
float | DestructibleDamage | If > 0.f, will cause damage to destructible meshes as well |
 |
TEnumAsByte< enum ERadialImpulseFalloff > | Falloff | How the force or impulse should fall off as object are further away from the center |
 |
float | ForceStrength | How strong the force should be |
 |
float | ImpulseStrength | How strong the impulse should be |
 |
TArray< TEnumAsByte< enum EObjectTypeQuery > > | ObjectTypesToAffect | The object types that are affected by this radial force |
 |
float | Radius | The radius to apply the force or impulse in |
