UAnimInstance::IsUpdatingAnimation

function Engine Since 4.15

#include "Animation/AnimInstance.h"

Access: public Specifiers: const

Description

Returns true if the anim instance is currently in the update phase of its animation tick. Useful for assertions or conditional logic that should only execute during the animation update pipeline.

Caveats & Gotchas

• Only returns true during the update phase window — calling it outside the animation tick always returns false. This is a narrow pipeline-phase check, not a general 'is animation active' query.
• If you need to know whether the anim instance is actively ticking at all (vs. being LOD'd out or paused), use NeedsUpdate instead.

Example

Assert during animation update C++

void UMyAnimInstance::UpdateLocomotionVariables()
{
    // Ensure this is only called during the animation update phase
    check(IsUpdatingAnimation());
    
    Speed = GetOwningActor()->GetVelocity().Size();
    Direction = CalculateDirection(GetOwningActor()->GetVelocity(), GetOwningActor()->GetActorRotation());
}
