UGameplayStatics::SetGlobalTimeDilation

function Engine Blueprint Since 4.0

#include "Kismet/GameplayStatics.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Sets the global time dilation, scaling how fast time advances for the entire game world. Useful for slow-motion effects or cinematic sequences.

Caveats & Gotchas

• This affects all actors and timers in the world — not per-actor. If you only want to slow a specific actor, set Actor::CustomTimeDilation on that actor instead.
• Values very close to 0 can cause floating-point instability in physics and animation. Keep TimeDilation above 0.0001 in practice.
• Not replicated. Clients must set their own dilation independently, or you must broadcast this call through a network RPC.

Signature

static ENGINE_API void SetGlobalTimeDilation(const UObject* WorldContextObject, float TimeDilation);

Parameters

Name	Type	Description	Default
WorldContextObject	const UObject*	Object used to retrieve the world context.	—
TimeDilation	float	Multiplier applied to global game time. 1.0 = normal speed, 0.5 = half speed, 2.0 = double speed.	—

Return Type

void

Example

Bullet-time slow motion on hit C++

// Slow the world to 20% speed for 0.5 seconds, then restore
UGameplayStatics::SetGlobalTimeDilation(this, 0.2f);
FTimerHandle Handle;
GetWorldTimerManager().SetTimer(Handle, [this]()
{
    UGameplayStatics::SetGlobalTimeDilation(this, 1.0f);
}, 0.5f, false);
