How to close the gui buttons

can some one ad some code how to close this buttons i can choose witch airplanes i can fly inside a level
only the buttons have to close when i select a button

public var distance = 5;
public var prefab : Transform;
public var prefab2 : Transform;
public var cam : GameObject;
public var cam2 : GameObject;

function OnGUI ()
{
if (GUI.Button(Rect(25,25,100,30), "f16a"))
{
var newPrefab=Instantiate(prefab,transform.position+transform.forward*distance,transform.rotation);
newPrefab.transform.position = transform.position + transform.forward * distance;
newPrefab.transform.rotation = transform.rotation;
var newCamera=Instantiate(cam, transform.position, transform.rotation);
}
else if (GUI.Button(Rect(125,25,100,30), "ww2"))
{
var newPrefab2=Instantiate(prefab2,transform.position+transform.forward*distance,transform.rotation);
newPrefab2.transform.position = transform.position + transform.forward * distance;
newPrefab2.transform.rotation = transform.rotation;
var newCamera2=Instantiate(cam2, transform.position, transform.rotation);
}
}

 

Code (csharp):

1.  
2. public var distance = 5;
3. public var prefab : Transform;
4. public var prefab2 : Transform;
5. public var cam : GameObject;
6. public var cam2 : GameObject;
7.  
8. private var showGUI = true;
9.  
10. function OnGUI ()
11. {
12.     if (showGUI)
13.     {
14.         if (GUI.Button(Rect(25,25,100,30), "f16a"))
15.         {
16.             var newPrefab=Instantiate(prefab,transform.position+tr ansform.forward*distance,transform.rotation);
17.             newPrefab.transform.position = transform.position + transform.forward * distance;
18.             newPrefab.transform.rotation = transform.rotation;
19.             var newCamera=Instantiate(cam, transform.position, transform.rotation);
20.             showGUI = false;
21.         }
22.         else if (GUI.Button(Rect(125,25,100,30), "ww2"))
23.         {
24.             var newPrefab2=Instantiate(prefab2,transform.position+ transform.forward*distance,transform.rotation);
25.             newPrefab2.transform.position = transform.position + transform.forward * distance;
26.             newPrefab2.transform.rotation = transform.rotation;
27.             var newCamera2=Instantiate(cam2, transform.position, transform.rotation);
28.             showGUI = false;
29.         }
30.     }
31. }

 

Thank you very much its working, thank for helping

 

Happy to help! BTW, next time if you put your code between [ code] and [/ code] tags, the forum will format it for you.
