UAnimInstance::NativeUpdateAnimation

function Engine Since 4.0

#include "Animation/AnimInstance.h"

Access: public Specifiers: ENGINE_APIvirtual

Description

Override in C++ subclasses to update animation variables every frame. This is the primary per-frame hook for driving animation state from gameplay — set variables here that your animation blueprint reads in its graph.

Caveats & Gotchas

• Always call Super::NativeUpdateAnimation(DeltaSeconds) to ensure base class logic runs (including propagation to linked instances if configured).
• This runs on the game thread before the parallel update. For thread-safe math that can run off the game thread, consider NativeThreadSafeUpdateAnimation or ParallelUpdateAnimation instead to reduce game thread cost.

Signature

ENGINE_API virtual void NativeUpdateAnimation(float DeltaSeconds);

Example

Update movement variables for anim graph C++

void UMyAnimInstance::NativeUpdateAnimation(float DeltaSeconds)
{
    Super::NativeUpdateAnimation(DeltaSeconds);
    if (APawn* Pawn = TryGetPawnOwner())
    {
        Speed = Pawn->GetVelocity().Size();
        bIsInAir = Pawn->GetMovementComponent()->IsFalling();
    }
}
