Create a Blueprint for a health pickup that restores health when overlapped by the player

SetMaterial — change material on mesh component at index

AddMappingContext — add Enhanced Input mapping context to player

Get subsystem: GetSubsystem(UEnhancedInputLocalPlayerSubsystem, GetPlayerController(0)). Call in EventBeginPlay on the Character or PlayerController. Priority: higher number overrides lower number mappings.

Create a Blueprint Actor for a collectible coin that rotates, plays a sound, and adds score when picked up

Create dynamic material and animate a parameter at runtime

Pattern: EventBeginPlay → GetMesh → CreateDynamicMaterialInstance(ElementIndex=0) → SetVariable(DynMat=ReturnValue). Then on Tick or timer: SetScalarParameterValue(ParameterName='Opacity', Value=SinWave). Or for color: SetVectorParameterValue(ParameterName='Color', Value=MakeLinearColor). Key: CreateDynamicMaterialInstance is called on the COMPONENT (GetMesh), not the actor. Must store the result before using Set*ParameterValue. ParameterName MUST match the name in the Material asset exactly.

PlayMontage — play an AnimMontage on a SkeletalMeshComponent

Call on the SkeletalMeshComponent. Get it via GetMesh() on Character. Returns montage length. Exec out is 'then'.

SetVectorParameterValue — set a color/vector parameter on a dynamic material
