Make player look at pointed target

Questions & Answers

Hi.
I’m working on a 3rd person game and trying to make the player look at the object the cursor points at.

what i try to do is sending a raycast from cursor, hitting the object, then calculating the direction from player to hit.point and rotating there.

#pragma strict
private var _mousePos		:Vector3;
private var _myTransform	:Transform;
var mouseMovementFactor		:float=1;

function Start () {
		_myTransform = transform;

}

function Update () {
	
	_mousePos = Input.mousePosition;
//	print(_mousePos);
	var myScreenPos:Vector3 = Camera.main.WorldToScreenPoint(_myTransform.position);
//	print(myScreenPos);
	var dir2Cursor:Vector3 = _mousePos-myScreenPos;
	//print(dir2Cursor);
	var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
	var hit:RaycastHit;
	var direction:Vector3;
	var rotation:Quaternion;
		if(Physics.Raycast (ray,hit,10000) && hit.collider.tag!="Player") 
		{
			direction = (hit.point - _myTransform.position);
			print("hitting "+hit.collider + "   direction from player: "+direction);
		}
	rotation = Quaternion.LookRotation(direction);

the part of rotating to look at the direction causes me problems.
as for now - the line print("hitting "+hit.collider + " direction from player: "+direction); prints exactly the object i’m touching.

what i tried so far was

rotation = Quaternion.LookRotation(direction);
	_myTransform.rotation = Quaternion.Slerp(_myTransform.rotation,rotation,Time.deltaTime*mouseMovementFactor);

player rotates rightwards only and would only slow down if i take cursor left.

	_myTransform.rotation.y = Quaternion.Slerp(_myTransform.rotation,rotation,Time.deltaTime*mouseMovementFactor).y;
	_myTransform.rotation.z = Quaternion.Slerp(_myTransform.rotation,rotation,Time.deltaTime*mouseMovementFactor).z;

(x makes it flip on its back)
makes it to slerp to a specific rotation and not move from there.

_myTransform.LookAt(hit.point);

makes it completely go crazy.

var newDir = Vector3.RotateTowards(_myTransform.forward, direction, mouseMovementFactor*Time.deltaTime, 0.0);
	_myTransform.rotation.y = Quaternion.LookRotation(newDir).y;
	_myTransform.rotation.z = Quaternion.LookRotation(newDir).z;

y - barely moves it
z makes it go strange irrelevent directions

please help?

Try this:

//This is good.
direction = (hit.point - _myTransform.position);
//And add this:
_myTransform.forward = direction.Normalize();

if wrong way, try the others:

_myTransform.forward = direction.Normalize() * -1; //backward

_myTransform.right = direction.Normalize(); //*-1 //backward
_myTransform.up = direction.Normalize(); //*-1 //backward
