20 results for impulse
One-shot force. bVelChange=true treats Impulse as velocity change.
Add ImpulseUE 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoPattern: OnDeath → GetMesh → SetSimulatePhysics(bSimulate=true) → AddImpulse(Impulse=MakeVector(X=0,Y=0,Z=500), bVelChange=true). For explosion: GetMesh → AddRadialImpulse(Origin=ExplosionLocation, Radius=500, Strength=1000, Falloff=RIF_Linear, bVelChange=false). Key: Always call SetSimulatePhysics BEFORE AddImpulse. AddImpulse input 'bVelChange=true' for direct velocity (ignores mass). AddRadialImpulse is on PrimitiveComponent.
bVelChange=true treats Impulse as direct velocity change (ignores mass). bVelChange=false treats it as a force impulse (mass-dependent).
AddImpulseUE 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agobXYOverride/bZOverride: if true, replaces current velocity. If false, adds to it.
LaunchCharacterUE 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoRequires Simulation Generates Hit Events on physics body.
Event HitUE 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoPattern: BoxCollision trigger, variable OverlappingActors(int)=0. OnBeginOverlap: OverlappingActors++ → Branch(OverlappingActors >= RequiredCount) → Activate. OnEndOverlap: OverlappingActors-- → Branch(OverlappingActors < RequiredCount) → Deactivate. Use interface or event dispatcher to notify connected actors (doors, platforms).
A blocking collision between two shapes. Fires OnHit on both actors. Use for solid impacts.
Fires when a physics collision happens. Use for impact effects, damage on contact.
ACharacter::LaunchCharacter. Good for knockback, bouncing, jumppads.
Launch CharacterUE 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoK2Node_EnhancedInputAction. ActionValue type depends on InputAction (Bool, Float, Axis2D, Axis3D). Triggers: Started, Ongoing, Triggered, Completed, Canceled.
EnhancedInputActionUE 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo ago
