UKismetAnimationLibrary::K2_StartProfilingTimer

function AnimGraphRuntime Blueprint Since 4.20

#include "KismetAnimationLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Starts a timer for measuring how long a section of an animation Blueprint graph takes to execute. Pair with K2_EndProfilingTimer to read the elapsed time.

Caveats & Gotchas

• Uses a single shared timer internally, so nesting two Start/End pairs on the same thread overwrites the first timer's start point rather than stacking.
• Intended for ad-hoc profiling in the animation Blueprint editor; it has no effect on shipped performance since the timer itself is cheap but tells you nothing unless paired with logging via K2_EndProfilingTimer.

Signature

static void K2_StartProfilingTimer()

Return Type

void

Example

Bracket a section of an anim graph C++

UKismetAnimationLibrary::K2_StartProfilingTimer();
// ... expensive animation logic here ...
float ElapsedMs = UKismetAnimationLibrary::K2_EndProfilingTimer(true, TEXT("MyAnimSection: "));
