Can't use a cursor controller script on multiple objects

I'm having issues with this cursor controller script.

Basically I want the cursor to change if the object it is attached to is visible and of course the cursor is over the object.

However, the script only works with one object at a time; if it is attached to more than one object, those other objects don't change the cursor.

1. 1. publicclass cursorController :MonoBehaviour
   2. {
   3. voidUpdate()
   4. {
   5. CursorMode cursorMode =CursorMode.Auto;
   6. Vector2 hotspot =Vector2.zero;
   7. RaycastHit2D hit =Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition),Vector2.zero);
   8. if(hit.collider !=false&&
   9. hit.collider.name == gameObject.name &&
   10. gameObject.renderer.enabled ==true)
   11. {
   12. Debug.Log(gameObject.name);
   13. var cursorTexture =Resources.Load("cursorTextureMess")asTexture2D;
   14. Cursor.SetCursor(cursorTexture, hotspot, cursorMode);
   15. }
   16. else
   17. {
   18. Cursor.SetCursor(null, hotspot, cursorMode);
   19. }
   20. }
   21. }

Thanks for any help in advance.

 

you need this skript only once. just attach it to you camera or controler object and change this line:

Code (CSharp):

1. if(hit.collider !=false && hit.collider.name == gameObject.name && gameObject.renderer.enabled ==true)

first off if the gameObject dident had an collider it would never get an hit so we dont need hit."collider !=false"

you probaly dont want every gameObject which has an collider get the new curser so we need to change "hit.collider.name == gameObject.name" to maybe hit.tag == "object"
make sure you add an tag with the strings "object" and mark your objects with it.

in the end we have something like that

Code (CSharp):

1. if(hit.tag == "object" && hit.gameObject.renderer != null && hit.gameObject.renderer.enabled ==true){

 

Thanks for trying to help but that didn't seem to work. I may just have to put aside this issue for now.

EDIT: This seems to have worked for me, though, so thanks for setting me on the right track!

if (hit.collider != null && hit.collider.CompareTag("CursorChange"))

 

oh for some reason in the docs they also check the collider: http://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html

maybe Physics2D.Raycast gets the hit with some other methode and not with colliders?
