Question by xyHeat · Mar 05, 2016 at 11:52 AM · buttonclick to move

Click to move [UNITY 2D C#]

Hi everybody ! I'm creating a 2D game and I want that my player move on click. The problem is that, when i click on a UI button, my player is moving and i don't want that (it is a spaceshooter and the button is the fire button ...)

So, this is my Script : void Update () {

     if (Input.GetMouseButtonDown(0))
     {
                 target = Camera.main.ScreenToWorldPoint(Input.mousePosition);
                 target.z = transform.position.z;
     }
 
     transform.position = Vector3.MoveTowards(transform.position, target, speed * Time.deltaTime);

I tried to use raycast but my player don't move..

Some one can help me ? Thank you, xyHeat

I finally find the good way ! Tjis if the final code :

     if (!EventSystem.current.IsPointerOverGameObject())
     {
         if (Input.GetMouseButtonDown(0))
         {
             target = Camera.main.ScreenToWorldPoint(Input.mousePosition);
             target.z = transform.position.z;
         }
     }
     transform.position = Vector3.MoveTowards(transform.position, target, speed * Time.deltaTime);


me, i did that :

     if (Input.GetMouseButtonDown(0)) {
         target = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         RaycastHit hit;
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Physics.Raycast(ray, out hit))
         {
             if (hit.collider.tag != "Button")
             {
                 target.z = transform.position.z;
             }
             else
             {
                 return;
             }

         }



Thank you again ! Bye !

You could try adding a eventsystem and have a plane behind the player and the ui which then registers mouseclicks, I think this should prevent the detecting of clicks when you click on ui elements.

I see that you can use a Event Trigger and in the code use the pointerEventData to get it's position.
