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.

Health regeneration over time with timer

Pattern: Variables RegenRate(float)=5.0, RegenDelay(float)=3.0, RegenTimerHandle. On damage received: ClearTimer(RegenTimerHandle) → SET timer(RegenDelay, RegenTick, looping=true). RegenTick function: Branch(Health < MaxHealth) → True: SET Health = FClamp(Health + RegenRate*DeltaSeconds, 0, MaxHealth). False: ClearTimer.

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

Checkpoint and autosave system with trigger volumes

Pattern: BP_Checkpoint with BoxTrigger, variable CheckpointID(int). OnBeginOverlap(Player) → DoOnce → CreateSaveGameObject(MySaveGame) → SET PlayerLocation, Health, Inventory, CheckpointID → SaveGameToSlot('AutoSave', 0). On death/respawn: LoadGameFromSlot('AutoSave') → Cast → TeleportTo(SavedLocation) → restore Health etc. Show 'Checkpoint Reached' UI briefly.

Health and damage system with ApplyDamage and EventAnyDamage

Dealing damage: Event → ApplyDamage(TargetActor, BaseDamage, InstigatorController, DamageCauser, DamageTypeClass). Receiving: EventAnyDamage → Damage output → Subtract_FloatFloat(CurrentHealth, Damage) → FClamp(Result, 0, MaxHealth) → SET CurrentHealth → Branch(CurrentHealth <= 0) → True: DestroyActor. Initialize CurrentHealth=MaxHealth in BeginPlay.

EventAnyDamage — receive any type of damage

Health system: take damage, clamp health, check death

Pattern: EventAnyDamage → Subtract_FloatFloat(A=CurrentHealth, B=Damage) → Clamp(Value=Result, Min=0, Max=MaxHealth) → SetVariable(Health=ClampResult) → Branch(Condition=(Health <= 0)) → True: call OnDeath custom event. Variables needed: Health (float), MaxHealth (float). EventAnyDamage output pin is 'Damage' (float). Clamp inputs: 'Value', 'Min', 'Max'. All floats.

Power — raise base to exponent power

Internal function name is MultiplyMultiply_FloatFloat (operator **).

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.
