Show GUI on collision

Question

Hi everyone, I have a simple script here I'm having a small problem with:

 var showGUI = false;
 var launcherUpgrade1 : Texture2D;
 
 
 function OnTriggerEnter (col : Collider) {
         
 
 if(col.name == "Player" && GUI.enabled == false) {
 GUI.enabled = true;
 }
 
 if(GUI.enabled == true) {
 OnGUI();
 }
 
 else if(GUI.enabled == false) {
 
 return;
 }
 }
 
 
 function OnGUI () {
    GUI.Box (Rect (10,10,100,50), GUIContent("400", launcherUpgrade1));
 }

So basically when the player collides with the gameobject t$$anonymous$$s script is attached to I want it to show the GUI. However, the GUI is automatically being shown as soon as the game starts. How can I fix t$$anonymous$$s?

You misunderstand GUI.enabled. It's not for that. It's for "greying out" UI elements. Try t$$anonymous$$s:

 var showGUI = false;
 var launcherUpgrade1 : Texture2D;
 
 function OnTriggerEnter (col : Collider) {
     if(col.name == "Player")
         showGUI  = true;
 }
 
 function OnGUI () {
    if (showGUI) {
        GUI.Box (Rect (10,10,100,50), GUIContent("400", launcherUpgrade1));
        ... rest of the GUI ...
    }
 }

Or, if you really do want it to grey out:

 function OnGUI () {
    GUI.enabled = showGUI;
    GUI.Box (Rect (10,10,100,50), GUIContent("400", launcherUpgrade1));
 }

make a script and name it

GUIControllerScript.cs

 using UnityEngine;

using System.Collections;

public class GUIControllerScript : MonoBehaviour {

 public bool ShowGUI = false;

 void Start () 
 
 {
 
 }
 
 void Update () 
 {
     if (ShowGUI)
     {
         G_U_I.Instance.enabled = true;
     }
     if (!ShowGUI)
     {
         G_U_I.Instance.enabled = false;
     }
 }

 void OnTriggerEnter(Collider col)
 {
     if (col.name == "Player")
     {
         ShowGUI = true;
     }
 }

}

and t$$anonymous$$s one name it

G_U_I.cs

 using UnityEngine;

using System.Collections;

public class G_U_I : MonoBehaviour { public static G_U_I Instance;

 void Start () 
 {
     Instance = t$$anonymous$$s;
 }
 
 void Update () 
 {
 
 }


 void OnGUI()
 {
     //Put ur GUI Script here
 }

}
