LaunchCharacter — apply a velocity impulse to a Character

bXYOverride/bZOverride: if true, replaces current velocity. If false, adds to it.

CreateDynamicMaterialInstance — create runtime modifiable material

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

AddImpulse — apply instant impulse to physics body

One-shot force. bVelChange=true treats Impulse as velocity change.

LaunchCharacter — launch character with velocity

ACharacter::LaunchCharacter. Good for knockback, bouncing, jumppads.

Create widget, add to viewport, and store reference

Pattern: EventBeginPlay → CreateWidget(OwningPlayer=GetPlayerController, WidgetType=WBP_MyWidget) → SetVariable(HUDWidget=ReturnValue) → CastTo<WBP_MyWidget>(HUDWidget) → Cast Succeeded → AddToViewport(ZOrder=0). Always store widget reference in a variable. CreateWidget inputs: 'OwningPlayer' (PlayerController) and 'WidgetType' (class). Exec in='execute', exec out='then'.
