UAnimInstance::GetDeltaSeconds

function Engine Blueprint Since 4.14

#include "Animation/AnimInstance.h"

Access: public Specifiers: ENGINE_APIUFUNCTIONBlueprintPure

Description

Returns the delta time in seconds used for the current animation update tick. Use this instead of the world delta time when writing thread-safe animation graph logic.

Caveats & Gotchas

• Marked BlueprintThreadSafe, so it can be called from worker-thread anim graph nodes. Calling the world's delta time APIs from those nodes is not thread-safe.
• During the first frame after initialization, the delta time may be 0.0 or very small — guard against division-by-zero if you use this as a divisor.

Example

Accumulate time in a thread-safe anim graph function C++

// In a BlueprintThreadSafe function inside the anim blueprint
AccumulatedTime += GetDeltaSeconds();
if (AccumulatedTime >= CycleDuration)
{
    AccumulatedTime = 0.f;
}
