Top down shooter game help

Hello, so I’m pretty new to Unity and i need some help making a top down shooter type game. The main problem I’m having is the targetting system. How would i go about making something rotate to face the mouse cursor?

Nevermind. I finally found it on this site and it’s working pretty well. Here’s the code if anyone is trying to do the same thing. :slight_smile:

// LookAtMouse will cause an object to rotate toward the cursor, along the y axis.


// To use, drop on an object that should always look toward the mouse cursor.

// Change the speed value to alter how quickly the object rotates toward the mouse.

// speed is the rate at which the object will rotate

var speed = 5;

function Update () {

// Generate a plane that intersects the transform's position with an upwards normal.

var playerPlane = new Plane(Vector3.up, transform.position);

// Generate a ray from the cursor position

var ray = Camera.main.ScreenPointToRay (Input.mousePosition);

// Determine the point where the cursor ray intersects the plane.

// This will be the point that the object must look towards to be looking at the mouse.

// Raycasting to a Plane object only gives us a distance, so we'll have to take the distance,

//   then find the point along that ray that meets that distance.  This will be the point

//   to look at.

var hitdist = 0.0;

// If the ray is parallel to the plane, Raycast will return false.

if (playerPlane.Raycast (ray, hitdist)) {

    // Get the point along the ray that hits the calculated distance.

    var targetPoint = ray.GetPoint(hitdist);

    // Determine the target rotation.  This is the rotation if the transform looks at the target point.

    var targetRotation = Quaternion.LookRotation(targetPoint - transform.position);

    // Smoothly rotate towards the target point.

  transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, speed * Time.deltaTime); // WITH SPEED

    //transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, 1); // WITHOUT SPEED!!!
