3d text as a button...

Hi all, really simple task here. What else do I need to get my 3D text to behave as a button..? I have this code on the text, its highlighting fine, do I need some kind of collision on the text itself?

Code (csharp):

1. var highlightColor = Color.yellow;
2.  
3. function OnMouseDown () {
4. renderer.material.color =  highlightColor;
5. Application.LoadLevel ("MainApp");
6. }
7.  
8. function OnMouseUp () {
9. renderer.material.color = Color(0,0,0);
10.  
11. }
12.  
13. function Start () {
14. var www = WWW ("http://server.co.uk/someasset_01.unity3d");
15. yield www;
16. // Get the designated main asset and instantiate it.
17. Instantiate(www.assetBundle.mainAsset);
18. }

thanks

just add a collider and use raycast
something like this:

Code (csharp):

1. private var hit : RaycastHit;
2. private var ray : Ray;
3. private var HitGameObject : GameObject;
4. static var PlayerCamera : GameObject;
5. public var rayDistance : float = 100;
6.  
7. function Awake()
8. {
9.     PlayerCamera = GameObject.Find("Main Camera");
10. }
11.  
12. function Update ()
13. {  
14.     ray = PlayerCamera.camera.ScreenPointToRay (Input.mousePosition);
15.    
16.     if(Input.GetMouseButtonDown(0))
17.     {
18.         if (Physics.Raycast (ray, hit, rayDistance))
19.         {
20.             HitGameObject = hit.collider.gameObject;
21.         }
22. }}

 

hi there,
Thanks for the reply.! I can't figure out where to put my code in this raycast script to get my level to load.... can you help.. i just get errors.! I have a collider on the 3d text.. just not sure where this code needs to be entered,.

Code (csharp):

1.  
2. Application.LoadLevel ("MainApp");
3.  

 

You don't need to use raycasting; just a box collider and OnMouseDown works fine.

Thanks Eric, Raycasting wasn't needed.! Thanks to synapsemassage, I got your code working too.

My new problem is getting my assetbundle to load OnMouseDown... this is what I have so far. I also don't fully understand the instantiate part either..

Code (csharp):

1.  
2.  
3. var highlightColor = Color.yellow;
4.  
5. function OnMouseDown () {
6. renderer.material.color =  highlightColor;
7. }
8.  
9. function Start () {
10. var www = WWW ("http://hosse.co.uk/someasset_01.unity3d");
11. yield www;
12. var progress : float
13. // Get the assetbundle and instantiate it.
14. Instantiate(www.assetBundle.mainAsset);
15. }
16.
