我想在吊臂上找到一个悬挂在起重机上的点,它与起重机的距离最小,起重机臂上有BoxCollider,我正在使用Physics.overlap方法. 如何从源对象中找到GameObject上最近的点? [1]:https://i.stack.imgur

您可以使用Collider.ClosestPoint
和
Collider.ClosestPointOnBounds
执行此操作.如果您还想检查自定义位置和旋转而不是使用对撞机的位置和旋转,请使用
Physics.ClosestPoint
.
其中3个函数的示例用法:
public Vector3 sourceObject; public Collider targetCollider; // Update is called once per frame void Update() { //Method 1 Vector3 closestPoint = targetCollider.ClosestPoint(sourceObject); //Method 2 Vector3 closestPointInBounds = targetCollider.ClosestPointOnBounds(sourceObject); //Method 3 Vector3 pos = targetCollider.transform.position; Quaternion rot = targetCollider.transform.rotation; Vector3 closestPointCollider = Physics.ClosestPoint(sourceObject, targetCollider, pos, rot); }
