FTimerManager::Tick

function Engine Since 4.0

#include "TimerManager.h"

Access: public Specifiers: ENGINE_API

Description

Advances all active timers by the given delta time, firing any whose expiry has been reached. Called automatically by the world each frame — you should never need to call this manually.

Caveats & Gotchas

• Looping timers with bMaxOncePerFrame=false can fire multiple times in a single Tick call if DeltaTime is large enough to span several periods. This can cause unexpected burst callbacks after hitches.
• Timers added during the execution of a callback are placed in the pending set and will not fire until the next Tick, preventing re-entrancy issues but delaying by one frame.

Example

Typical engine call site (for reference only) C++

// Called by UWorld::Tick — you do not invoke this yourself.
// Shown here to illustrate how delta time flows into the timer manager.
void UWorld::Tick(ELevelTick TickType, float DeltaSeconds)
{
    // ...
    GetTimerManager().Tick(DeltaSeconds);
    // ...
}
