Respawn system: death → delay → respawn at PlayerStart

In Character BP: OnDied (custom event) → SetActorHiddenInGame(true) → SetActorEnableCollision(false) → Disable input: GetController → DisableInput → Delay(Duration=3.0) → GetGameMode → CastTo<BP_GameMode> → RestartPlayer(GetController) → SetActorHiddenInGame(false) → SetActorEnableCollision(true) → EnableInput. In GameMode RestartPlayer: Gets nearest PlayerStart → SetActorLocation to PlayerStart → calls OnPossess. OR manual: GetAllActorsOfClass(PlayerStart) → Random select → SetActorLocationAndRotation(PlayerStart.Location, PlayerStart.Rotation).

Pickup and collectible system with overlap trigger

Pattern: Pickup actor with SphereCollision(overlap), StaticMesh visual. OnComponentBeginOverlap → CastTo PlayerCharacter → Success: call AddScore/AddItem interface on player → PlaySoundAtLocation → SpawnEmitterAtLocation → DestroyActor(self). Set collision to OverlapOnlyPawn for performance.

Event BeginPlay — fires once when actor is spawned or game starts

OnComponentHit — hit event on specific component
