SetTimerByFunctionName — set timer that calls a function

K2_SetTimer. Prefer SetTimerByEvent for type safety.

GetTimeSeconds — get time since level started

Day night cycle with directional light rotation over time

Pattern: Variables TimeOfDay(float)=12.0, DayLengthMinutes(float)=10. Tick: TimeOfDay += (DeltaSeconds/DayLengthMinutes/60)*24 → FMod(TimeOfDay, 24) → MapRangeClamped(TimeOfDay, 0, 24, 0, 360) → MakeRotator(SunPitch, 0, 0) → SetActorRotation(SunLight). Update sky SunDirection and light color/intensity based on time.

SetTimerByEvent — set timer that fires a custom event delegate

K2_SetTimerDelegate. Safer than FunctionName version. Create delegate from custom event.

SetTimerByFunctionName — call a function repeatedly on a timer

Timer with Set Timer by Function Name for repeating actions

Pattern: BeginPlay → K2_SetTimer(Self, 'MyFunction', 2.0, true) → store TimerHandle. Stop: ClearAndInvalidateTimerByHandle(TimerHandle). Prefer SetTimerByEvent over FunctionName for type safety. Delay node is simpler for one-shot but only works in Event Graph.

Elevator or moving platform with timeline and trigger

Pattern: Variables StartLocation(Vector), EndLocation(Vector). BeginPlay: SET StartLocation=GetActorLocation. Timeline MoveTimeline(Alpha 0→1 over Duration). Trigger overlap/button press → Play Timeline. Timeline Update: VLerp(StartLocation, EndLocation, Alpha) → SetActorLocation(Self, Result, bSweep=true). Finished: Delay → Reverse Timeline.

Timer

Schedules a function to run after a delay or on a repeating interval. Cleaner than Delay for repeating work.

SetGlobalTimeDilation — speed up or slow down game time

UGameplayStatics. 1.0=normal, 0.5=half speed, 2.0=double speed. Minimum 0.0001.
