UKismetSystemLibrary::K2_TimerExists

function Engine Blueprint Since 4.0

#include "Kismet/KismetSystemLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Checks whether a timer is currently set for the given object and function pair, whether it is running or paused. Shown in Blueprint as "Does Timer Exist by Function Name".

Caveats & Gotchas

• Matches the function by binding a delegate to Object/FunctionName; if the name doesn't resolve to a UFUNCTION on Object, it logs a warning and returns false rather than erroring.
• Returns true even if the matching timer is currently paused — use K2_IsTimerPaused if you need to distinguish a paused timer from a running one.
