Using the ray detection method, the main camera sends a ray to the position of the mouse
Declare variable private float camLeagth = 100;//The length of the ray
//private LayerMask floorMask;//Number of levels on the ground
private int floorMask;
To get the ground layer, write it in the Start method or the Awake method
floorMask = LayerMask.GetMask("Floor");//Layer name, get the layer
Ray control rotation
//Send a ray from the origin of the main camera to the position of the mouse
Ray camRay = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
//If the ray detection is successful
if(Physics.Raycast(camRay,out hit,camLeagth,floorMask))
{ Debug.Log("Ray"); //Steer according to the mouse position Vector3 playerMouse = hit.point - transform.position;//Vector calculation rb.MoveRotation(Quaternion.LookRotation(playerMouse)) ;//rotate // //transform.LookAt(hit.point); }
