Game Object under Mouse after selection

Hello,

I´ve some GUI Buttons. With a mouse-left-click on one button you can choose a game object. With another left-click on the terrain you can place it.

Now i want to see after the click on the button, the game object under my mouse (maybe a bit transparent), so you can place it a lot easier. Here is the the part of the code:

Code (csharp):

1. function Update () {
2.  
3.  
4.     if(Input.GetMouseButtonDown(0))
5.     {
6.  
7.     var hit : RaycastHit;
8.     var ray : Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
9.  
10.     if(Physics.Raycast(ray,hit,300))
11.     {
12.  
13.     Instantiate(buildingType,hit.point,Quaternion.identity);
14.  
15. }

 

Try adding an OnMouseEnter() function into your class.

 

Could you describe it a bit more.

The building should only be under the mouse curser, after clicking the GUI element. It should disappear with the mouse-left click (for placing the object), or the right-mouse to cancel the action.

The example which you can find in the docs hasn´t much to do with that issue, it´s more like a mouse-over.

Code (csharp):

1. function OnMouseEnter () {
2.     renderer.material.color = Color.red;
3. }

 

Still couldn´t figure it out.

 

/push

 

Code (csharp):

1.  
2. #pragma strict
3.  
4. import System;
5.  
6. function Update () {
7.     if(Input.GetMouseButtonDown(0))
8.     {
9.         var hit : RaycastHit;
10.         var ray : Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
11.         if(Physics.Raycast(ray,hit,300))
12.         {
13.             hit.transform.renderer.material.color = Color.red;
14.         }
15.     }
16. }
17.  

That code would make something you click change color. Now its up to you to decide how you should make it change back after you unclick and what not.
I would recommend maybe a list of objects you clicked, then if you clicked the right button, go throw them and change material back?

 

Thanks, but i don´t need a color change.

 

No tips?
