Question

我有一个对撞机预制件（一个立方体，与立方体大小的盒子对撞机）。在一个场景中，我的玩家与它完美碰撞，但在另一个场景中，玩家在对撞机的一侧出现故障并相位而不是另一侧。旋转它会改变它出现故障的一侧，因此它总是面向相同的全局方向。

可能导致这种情况的原因是什么？我已确保播放器和对撞机对象的预制件在场景中完全相同，除了移动播放器的播放器控制器脚本以及具有将刚体的速度设置为0的OnCollisionExit条件之外，没有任何影响碰撞。 / p>

添加了以下代码。输入是用操纵杆（想想直升机中的操纵杆）。就像我说的那样，碰撞通常是完美的，但由于某些原因，只有在这个场景中它不会。我怀疑它是某种层次结构或严格的问题，但我已经检查了所有的东西。

当GameObject有Rigidbody和Collider并且你想要碰撞时，不按transform.Translate移动对象，或者用transform.Rotate或{{1}将其旋转}。当你这样做时，不会发生碰撞。

使用transform.RotateAround和碰撞移动GameObject的正确方法是使用Rigidbody.MovePosition函数。

旋转它的正确方法是使用Rigidbody.MoveRotation功能。

Rigidbody.MovePosition的示例：

Rigidbody

Rigidbody.MoveRotation的示例：

float h = Input.GetAxisRaw("Horizontal");
float v = Input.GetAxisRaw("Vertical");

Vector3 tempVect = new Vector3(h, 0, v);
tempVect = tempVect.normalized * speed * Time.deltaTime;
rb.MovePosition(transform.position + tempVect);

您需要将Quaternion deltaRotation = Quaternion.Euler(eulerAngleVelocity * Time.deltaTime); rb.MoveRotation(rb.rotation * deltaRotation);，transform.Translate和transform.Rotate替换为这些。
