AddForce — apply continuous force to physics body

Continuous force — apply every frame. Use AddImpulse for one-shot.

Physics Body

A SceneComponent with simulate-physics enabled. Driven by forces, gravity, collisions instead of explicit transforms.

SetScalarParameterValue — set a float parameter on a dynamic material

ParameterName must match the parameter name in the Material exactly (case-sensitive).

CreateDynamicMaterialInstance — create runtime modifiable material

UPrimitiveComponent method. Store result in variable and reuse. Create once in BeginPlay.

Less (float) — A < B

SetPhysicsLinearVelocity — directly set linear velocity of physics body

SetPhysicsLinearVelocity — directly set linear velocity of a physics body

AddTorqueInDegrees — apply rotational torque to physics body

AddForce — apply a continuous force to a physics body each frame

Hit

A blocking collision between two shapes. Fires OnHit on both actors. Use for solid impacts.
