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.

Add

Standard addition. Works on Integer, Float, Vector, Rotator, etc — UE picks the right overload from pin types.

CreateDynamicMaterialInstance — create a runtime-editable material copy

Must call this before SetScalarParameterValue/SetVectorParameterValue. Store the result in a variable for reuse.

Enhanced Input

The modern UE input system (5.0+). InputAction + InputMappingContext replace the legacy axis/action mappings.

OR Boolean — logical OR of two booleans
