GetTimeSeconds — time elapsed since level started in seconds

Pure node. Useful for time-based calculations. Resets when level loads.

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.

SetPercent on ProgressBar — set progress bar fill amount

UProgressBar::SetPercent. 0.0 to 1.0 range.

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.

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.

GetTimeSeconds — get time since level started

GetUnpausedTimeSeconds — time excluding paused periods

SetPercent — set ProgressBar fill amount (0.0 to 1.0)

InPercent: 0.0=empty, 1.0=full. Use Divide to convert (CurrentHealth/MaxHealth).

GetWorldDeltaSeconds — get this frame's delta time in seconds

Pure node. Same value as EventTick's DeltaSeconds output. Use for frame-rate-independent motion.

Event Tick — fires every frame with DeltaSeconds
