Player + Camera to Follow Mouse Cursor

Unity Engine
1

I am trying to get my player+camera to follow my mouse cursor at a distance in a top down view game…

here is the game project demo: http://kuroato.com/ghostwarrior/

I was able to get the player model to follow the mouse, but the camera does not move or follow the player…

I am using a script i came across via Google called SmoothFollow2D.js, any tips to get this working properly?

 var target : Transform;
    var smoothTime = 0.3;
    var xOffset : float = 1.0;
    var yOffset : float = 1.0;

    private var thisTransform : Transform;
    private var velocity : Vector2;


    function Start()
    {
           thisTransform = transform;
    }

    function LateUpdate()
    {

           thisTransform.position.x = Mathf.Lerp( thisTransform.position.x, target.position.x + xOffset, Time.deltaTime * smoothTime);

           thisTransform.position.y = Mathf.Lerp( thisTransform.position.y, target.position.y + yOffset, Time.deltaTime * smoothTime);

    }

Using a character controller would probably be better than translating your object.

Start here:

This is a basic character controller script. But it will need to be changed some to achieve what you are going after.

var speed : float = 6.0;
var jumpSpeed : float = 8.0;
var gravity : float = -Physics.gravity.y * 2;
var cameraDistance : float = 10;

private var moveDirection : Vector3 = Vector3.zero;


function Update() {
    var controller : CharacterController = gameObject.GetComponent(CharacterController);
    if(!CharacterController) controller = gameObject.AddComponent(CharacterController);
    
    // setup a plane, ray and collector for a raycast.
	var plane:Plane = new Plane(transform.up, transform.position);
	var ray:Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
	var dist:float;
	
	// raycast the plane and collect the collector
	// this should always go off
	if(plane.Raycast(ray, dist)){
		// make your player LookAt the point.
		transform.LookAt(ray.GetPoint(dist));
	}
    
    if (controller.isGrounded) {
    	// get the inputs
		moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
		// transform them into a direction based on the direction of the player.
		moveDirection = transform.TransformDirection(moveDirection);
		moveDirection *= speed;
    }

    // Apply gravity
    moveDirection.y -= gravity * Time.deltaTime;
    
    // Move the controller
    controller.Move(moveDirection * Time.deltaTime);
    
    // set the camera to the palyers current position and move it up a distance.
    Camera.main.transform.position = transform.position + Vector3.up * cameraDistance;
    // just in case, make it look at the player.
    Camera.main.transform.LookAt(transform);
}

Read over it, understand it, test it and see if you have any questions.
