Selecting Object. Changing material via script.
Here I am trying to use Unity for the first time. I Managed to make a simple FPS level and to make an object that, with the Raycast thingy, notices when I'm looking at it from reasonably near. Now I would like for it to be 'selected' when I look at it that way, that is, I crated another material with an outline and I would like that the object's material change when I look at it. By copying the Raycast code I had on a script on the player and pasting it in a script on the object I created this:
Shader shader1 = Shader.Find ("Toon/Lighted");
Shader shader2 = Shader.Find ("Toon/Lighted Outline");
RaycastHit hit;
Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width/2, Screen.height/2, 0));
renderer.material.shader = shader1;
if(Physics.Raycast(ray, out hit, 2))
{
if(hit.collider.tag == "Computer")
{
//Change material
renderer.material.shader = shader2;
if( Input.GetButton ("Fire1") ) {
//respawn
renderer.material.shader = shader1;
}
}
}
Since the camera is a child of the player it should work, but (even though it doesn't give me any errors) it doesn't, the material doesn't change. I know that there's a simpler function that should allow objects to know when the mouse overs over them, but it's possible to set a distance from the object for that to work? And it even works with FPS?
Thanks for your help.
You don't want to change the shader, because when you do this Unity is most likely to copy the old parameters to a new shader. Instead add 2 public variables with materials, create them and assign in the inspector and change the material (renderer.material = yourMaterial).
I think I got it, but I'm not sure about the kind of variable I'm supposed to use for materials.
var your$$anonymous$$aterial : $$anonymous$$aterial; // uJS
http://docs.unity3d.com/Documentation/ScriptReference/$$anonymous$$aterial.html

Edit :
public $$anonymous$$aterial your$$anonymous$$aterial; // C#
If you look at the Unity Scripting Reference, on the right above the script example, there is a drop-down menu, by default set to JavaScript. Click on this, then select C# to see the example in C#
I'm working with C#, that code doesn't work and in the documentation doesn't seem to be clear enough about how I'm supposed to do it in C#. Somebody have an idea?
public $$anonymous$$aterial your$$anonymous$$aterial;
That is how you can declare variables in C#. And don't forget to assign it in the inspector.
I can't bloody believe it. I wrote "material" without the capital $$anonymous$$. Thank you, now it works perfectly. I think it's about time to make it a little bit neater.
