Rotator

A 3D rotation (Pitch, Yaw, Roll) in degrees. Combine with Vector for full positioning.

Append — concatenate two strings into one

Pure node. For multiple strings, chain multiple Append nodes or use Format Text.

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.

ComposeRotators — add two rotators together

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

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

PlayMontage — play an AnimMontage on a SkeletalMeshComponent

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

Add_VectorVector — add two vectors

Sprint system with stamina drain and recovery

Pattern: Variables bIsSprinting(bool), Stamina(float)=100, MaxStamina(float)=100, SprintSpeed(float)=1200, WalkSpeed(float)=600, DrainRate(float)=20, RecoverRate(float)=10. Sprint pressed: bIsSprinting=true → SetMaxWalkSpeed(SprintSpeed). Released: bIsSprinting=false → SetMaxWalkSpeed(WalkSpeed). Tick: Branch(bIsSprinting) → Stamina -= DrainRate*DT. Else: Stamina += RecoverRate*DT. Clamp(0, Max). If Stamina<=0 → force stop sprint.

Concat_StrStr — concatenate two strings
