射线检测-unity

与最近物体碰撞取得位置:

private Vector3 GetMousePoint() { Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit; bool isCollider = Physics.Raycast(ray, out hit); if (isCollider) { return hit.point; } return Vector3.zero; }

与指定层的物体碰撞:
bool isCollider =Physics.Raycast(ray, out hit, 1000, LayerMask.GetMask("your define"));

【射线检测-unity】另外collider相当于游戏物体了
hit.collider.GetComponent();
