Question

我添加了购买的3D僵尸模型，我想多次添加它，所以有一群僵尸在追逐玩家（他的相机）。 DAE文件（僵尸）我有几个动画（攻击，步行，运行等）。我添加了几个这些僵尸模型，它们都出现在我希望它们出现的位置上（先前确定的坐标存储在僵尸数组中）当它们出现在屏幕上时，它们会执行DAE文件中显示的所有动画。

现在我的问题是：是否可以添加此DAE僵尸模型但是在指定的框架中显示它？例如2-122？到目前为止我的代码（我删除了不必要的内容）

/* SESSION FUNCTIONS */

func session(_ session: ARSession, didFailWithError error: Error)
{
    // Present an error message to the user

}

func sessionInterruptionEnded(_ session: ARSession)

使用ARKit的动画3D模型。迅速
