[Duplicated Question] Change Object material on mouse click

Question already posted at http://answers.unity3d.com/questions/173658/change-object-material-on-mouse-click.html

Hi all,

In a game I am currently building I would like players to click on models within the environment to change the material used on that object. For example, a player can click on the curtains to cycle through a range of designs.

I have a script which works, but I would like each object in a scene to act independently, currently if the script is attached to more than one object, all will change when the mouse is clicked.

I would like it so the script recognises which object I am clicking on and only changes the material on that model, I have mesh colliders on all of the models.

Code:

var myMaterials : Material[]; var NextMaterial : int = 0;

function NextMaterialUsed() { renderer.material = myMaterials[NextMaterial]; if(NextMaterial < myMaterials.length-1) NextMaterial += 1; else NextMaterial = 0; }

function Update () { if (Input.GetButtonDown ("Fire1")) {

     var ray :Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
     var hit: RaycastHit;
    
      if (Physics.Raycast (ray, hit, 100.0))
       {
         // Changes texture if hit
                NextMaterialUsed();
     }
 }

}
