Block raycast through the UI

Code (CSharp):

1. public Camera cam;
2.  
3.     public NavMeshAgent agent;
4.  
5.     // Update is called once per frame
6.     public void MoveToLocation()
7.     {
8.         Ray ray = cam.ScreenPointToRay(Input.mousePosition);
9.         RaycastHit hit;
10.  
11.         if (Physics.Raycast(ray, out hit))
12.         {
13.             agent.SetDestination(hit.point);
14.         }
15.     }

how do i stop the above code from executing on my UI or buttons? my player keeps moving with every click when i access my menu

 

Try to add a GraphicRaycaster to the Canvas.

The Graphic Raycaster is used to raycast against a Canvas. The Raycaster looks at all Graphics on the canvas and determines if any of them have been hit.

thank u... will have a loook

 

Code (CSharp):

1. public Camera cam;
2.     public NavMeshAgent agent;
3.     // Update is called once per frame
4.     public void MoveToLocation()
5.     {
6.         Ray ray = cam.ScreenPointToRay(Input.mousePosition);
7.         bool isOverUI = UnityEngine.EventSystems.EventSystem.current.IsPointerOverGameObject();
8.         if (Physics.Raycast(ray, out RaycastHit hit) && ! isOverUI)
9.         {
10.             agent.SetDestination(hit.point);
11.         }
12.     }

Edit: You'll need a EventSystem component in scene.

 

Thank u so much for your input...

 

Code (CSharp):

1. private bool DefineOnUI()
2.     {
3.         //Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
4.         if (EventSystem.current.IsPointerOverGameObject())
5.         {
6.             Debug.Log("Clicked on the UI");
7.             return true;
8.         }
9.         else
