Timer

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

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.

Timer: call a function repeatedly using SetTimerByFunctionName

Pattern: EventBeginPlay → SetTimerByFunctionName(Object=self, FunctionName='OnTimerFired', Time=1.0, bLooping=true). Create a separate custom event/function named 'OnTimerFired' — this is what the timer will call. SetTimerByFunctionName inputs: 'Object' (Object, use 'self'), 'FunctionName' (string), 'Time' (float, interval in seconds), 'bLooping' (bool). Output: 'ReturnValue' (TimerHandle).

SetTimerByFunctionName — call a function repeatedly on a timer

DoN — execute N times then stop

DoOnce — execute only the first time, block subsequent calls

Macro. Call Reset input to allow re-triggering.

string

DoOnce — execute the output only the first time it is called

Has 'Reset' exec input to allow it to fire again. Default bStartClosed=false means it fires first time.

DoOnce

Lets execution through once, then blocks subsequent attempts until Reset is called. Useful for one-shot triggers.

RetriggerableDelay — delay that resets if triggered again
