플레이어를 바라보는 모션워핑 버그수정

AI몬스터가 크기가 커질경우 플레이어가 밑에 있으니

플레이어를 향해 모션워핑을 할경우 밑을 향한채로 루트모션이 회전해버리니 ai가 땅에 박혀버리는 현상이 일어났다

 

수정전코드

void ABasicSkeletonEnemy::MotionWarpingPlayer()
{
	FVector playerLocation = aiController->GetBlackboardComponent()->GetValueAsVector(TEXT("PlayerLocation"));
	if (motionWarpComponent)
	{
		FVector enemyLocation = GetActorLocation(); 
		FVector playerDirection = playerLocation - enemyLocation;
		FRotator playerRotation = playerDirection.Rotation();

		FTransform playerTransform(playerRotation, playerLocation);
		motionWarpComponent->AddOrUpdateWarpTargetFromTransform(TEXT("PlayerTarget"), playerTransform);
	}
}

 

playerDirection.Rotation()에서 얻은 회전값에서 Yaw만 추출해서 새로운 FRotator로 변경해주었습니다

수정후

void ABasicSkeletonEnemy::MotionWarpingPlayer()
{
	FVector playerLocation = aiController->GetBlackboardComponent()->GetValueAsVector(TEXT("PlayerLocation"));
	if (motionWarpComponent)
	{
		FVector enemyLocation = GetActorLocation(); 
		FVector playerDirection = playerLocation - enemyLocation;

		//only yaw
		float yaw = playerDirection.Rotation().Yaw;
		FRotator playerRotation(0.f, yaw, 0.f);

		FTransform playerTransform(playerRotation, playerLocation);
		motionWarpComponent->AddOrUpdateWarpTargetFromTransform(TEXT("PlayerTarget"), playerTransform);
	}
}

 

더이상 z축으로 고꾸라지지않습니다
