Movement towards mouse position

When creating a video game you'll sometimes need a more specific movement while playing or want to move along with your cursor's movement.

By only adding the following script called LookAtMouse to your player and adding an initial speed you will star to move along your mouse in the game.

using UnityEngine; using System.Collections; public class LookAtMouse : MonoBehaviour { // speed is the rate at which the object will rotate public float speed; void FixedUpdate() { // Generate a plane that intersects the transform's position with an upwards normal. Plane playerPlane = new Plane(Vector3.up, transform.position); // Generate a ray from the cursor position Ray 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. float hitdist = 0.0f; // If the ray is parallel to the plane, Raycast will return false. if (playerPlane.Raycast(ray, out hitdist)) { // Get the point along the ray that hits the calculated distance. Vector3 targetPoint = ray.GetPoint(hitdist); // Determine the target rotation. This is the rotation if the transform looks at the target point. Quaternion targetRotation = Quaternion.LookRotation(targetPoint - transform.position); // Smoothly rotate towards the target point. transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, speed * Time.deltaTime); } } }
