Anim instance

Montage behavior

Thanks to zomg on the Unreal Source Discord for some insights after hitting this problem

You can know if any montages are running (using a class reference) by using GetInstanceForMontage or GetActiveInstanceForMontage (“instance” being the actual montage running).

But watch out, when the running instance is blending out, the anim instance will not consider it as active.

So if for example you want to check if a montage is currently running (active or blending out), and if so run another montage:

UAnimInstance* AnimInstance = GetMesh()->GetAnimInstance();
if (auto* CurrentAnim = AnimInstance->GetInstanceForMontage(NPCMontages->PickupMontage))
{
	FOnMontageEnded PlayEndDelegate = FOnMontageEnded::CreateWeakLambda(this, [PlayPickupAnim](UAnimMontage*, bool)
	{
		PlayPickupAnim();
	});
	CurrentAnim->OnMontageEnded = PlayEndDelegate;
}
else
{
PlayPickupAnim();
}
