Creating responsive menu

Here is my script which I have attached to a 3D Text:

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent(typeof(Renderer))]
 public class ResponsiveTest: $$anonymous$$onoBehaviour 
 {
     public Vector2 screenPosition = new Vector2(0, 0);
  
     void Update () 
     {
        Vector3 tempScreenPosition = screenPosition;
        tempScreenPosition.z = -Camera.main.transform.position.z;
  
        Vector3 worldPosition = Camera.main.ScreenToWorldPoint(tempScreenPosition);
        worldPosition.x -= renderer.bounds.size.x * tempScreenPosition.x / Screen.width;
        worldPosition.y += renderer.bounds.size.y * (1 - tempScreenPosition.y / Screen.height);
        transform.position = worldPosition;
     }
 }

And this is my menu button script (JavaScript): #pragma strict //The main menu script

 private var ray : Ray;
 private var hit : RaycastHit;
 
 function Update() 
 {
     if(Input.Get$$anonymous$$ouseButton(0))
     {
         ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         
         if(Physics.Raycast(ray, hit))
         {
             if(hit.transform.name == "Text(Play)")
             {
                 Application.LoadLevel("Landing");
             }
         }
     }
 }
 
 //Colour change
 function On$$anonymous$$ouseEnter()
 {
     renderer.material.color = Color.green;
 }
 
 function On$$anonymous$$ouseExit()
 {
     renderer.material.color = Color.white;
 }

Now my 3D Text is responsive but button control stopped working... What is wrong?

The first script shouldn't block the second script. Do you still have a collider attached?

Yes the collier is still attached... I'm not quite sure why its not working. Also would you be able to explain in detail what each statement does. Trying to understand it but not quite get it...

Yes, the calculations prevent only the need to change the anchor of the text mesh (the anchor should be always in the upper left here).

Get the world position:

 Vector3 worldPosition = Camera.main.ScreenToWorldPoint(tempScreenPosition);

Calculate the position/screen ratio

 //returns a float 0 to 1 where 0 is left and 1 is right 
 tempScreenPosition.x / Screen.width 

$$anonymous$$ultiply that by the meshs width to get the desired offset

 //gives 0 offset on the left (we need no offset because the anchor is also left)
 //and the meshs width on the right. 
 renderer.bounds.size.x * ratio

Finally subtract this value

 worldPosition.x -= offset

So the more the mesh moves to the right the higher the offset in relation to the mesh.width/screen.width-ratio to compensate the meshs anchor position.

If you don't $$anonymous$$d recreating your menu, then you should possibly look at the all new Unity 4.6 UI system. it's simple and powerful. Anchors is the word you should be looking for. Place the anchors of the UI element to the corners. That's it, the UI element is responsive. Check the below link for more info
