FTimerManager::HasBeenTickedThisFrame

function Engine Since 4.0

#include "TimerManager.h"

Access: public Specifiers: inline

Description

Returns true if this timer manager has already been ticked during the current frame. Useful for subsystems that want to avoid double-ticking a shared timer manager.

Caveats & Gotchas

• Comparison is done against GFrameCounter, which is a global engine frame counter. If you call this outside of the game thread, GFrameCounter may be mid-update and the result is unreliable.
• Returns false in the first frame before the manager's first Tick call, which can mislead initialization code that checks it eagerly.

Signature

bool inline HasBeenTickedThisFrame() const

Return Type

bool

Example

Guard against double-tick C++

void UMySubsystem::Tick(float DeltaTime)
{
    FTimerManager& TM = GetWorld()->GetTimerManager();
    if (!TM.HasBeenTickedThisFrame())
    {
        // perform work that depends on timers being current
    }
}
