UAnimInstance::SetPropagateNotifiesToLinkedInstances

function Engine Blueprint Since 4.24

#include "Animation/AnimInstance.h"

Access: public Specifiers: BlueprintCallableUFUNCTION

Description

Controls whether animation notifies fired on this instance are forwarded to any linked child anim instances. Useful when a parent layer fires a notify that multiple child layers need to respond to.

Caveats & Gotchas

• Enabling propagation means child instances receive the parent's notifies in addition to their own. If a child has its own copy of the same notify, it may effectively fire twice — once from its own animation and once propagated from the parent.
• Propagation flows from parent to children, not transitively through multiple layers unless each intermediate instance also has propagation enabled.

Signature

void SetPropagateNotifiesToLinkedInstances(bool bSet) { bPropagateNotifiesToLinkedInstances = bSet; }

Parameters

Example

Enable notify propagation to child layers C++

void UMyAnimInstance::NativeInitializeAnimation()
{
	Super::NativeInitializeAnimation();
	// Forward footstep notifies to locomotion child layer
	SetPropagateNotifiesToLinkedInstances(true);
}
