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

string

Add

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

Less (float) — A < B

Multiply

Standard multiplication. UE 5.5+ defaults to Multiply_Double; older code may use Multiply_Float — both work in Blueprints.

PlayMontage — play an AnimMontage on a SkeletalMeshComponent

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

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.

FCeil — round up to nearest integer

RandomBoolWithWeight — random bool with probability weight

Weight 0.0=always false, 1.0=always true, 0.5=50%.

Float

A real number with decimals. UE 5.0+ uses double-precision by default. Use for distances, percentages, time.
