Question by salad__fingers · Feb 11, 2013 at 07:33 PM · guibuttondisplay

GUI Buttons Not Displaying

I have tried in both Unity 3 and Unity 4, but neither will display the GUI buttons. I am following the remixgames FPS tutorial, for anyone wondering. Thanks.

This is the code:

 using UnityEngine;
 using System.Collections;
 
 public class MenuManager : MonoBehaviour
 {
     public string CurrentMenu;
     
     void Start()
     {
         CurrentMenu = "main";
     }
     
     void OnGui()
     {
         if(CurrentMenu == "main")
             Menu_Main();
         if(CurrentMenu == "Lobby")
             Menu_Lobby();
         if(CurrentMenu == "Host")
             Menu_HostGame();
     }
     
     public void NavigateTo(string nextmenu)
     {
         CurrentMenu = nextmenu;
     }
     
     private void Menu_Main()
     {
         //Main Menu Buttons
         if (GUI.Button(new Rect(10, 10, 200, 50), "Host Game"))
         {
             NavigateTo("Host");
         }
     }
     
     private void Menu_HostGame()
     {
         //Buttons for Hosting
         if (GUI.Button(new Rect(10, 10, 200, 50), "Back"))
         {
             NavigateTo("main");
         }
         if (GUI.Button(new Rect(10, 60, 200, 50), "Start Match"))
         {
             
         }
     }
     
         private void Menu_Lobby()
     {
         
     }
 }

Change OnGui() to OnGUI().

Thank you! I have a new error in the addition to the script that I have been working on. Line 60,68 Unexpected symbol "$$anonymous$$atch$$anonymous$$axPlayers"

 using UnityEngine;
 using System.Collections;
 
 public class $$anonymous$$enu$$anonymous$$anager : $$anonymous$$onoBehaviour
 {
     public string Current$$anonymous$$enu;
     
     public int $$anonymous$$atchName = "";
     public int $$anonymous$$atchPassword = "";
     public int $$anonymous$$atch$$anonymous$$axPlayers = 32;
     
     void Start()
     {
         Current$$anonymous$$enu = "main";
     }
     
     void OnGUI()
     {
         if(Current$$anonymous$$enu == "main")
             $$anonymous$$enu_$$anonymous$$ain();
         if(Current$$anonymous$$enu == "Lobby")
             $$anonymous$$enu_Lobby();
         if(Current$$anonymous$$enu == "Host")
             $$anonymous$$enu_HostGame();
     }
     
     public void NavigateTo(string nextmenu)
     {
         Current$$anonymous$$enu = nextmenu;
     }
     
     private void $$anonymous$$enu_$$anonymous$$ain()
     {
         //$$anonymous$$ain $$anonymous$$enu Buttons
         if (GUI.Button(new Rect(10, 10, 200, 50), "Host Game"))
         {
             NavigateTo("Host");
         }
     }
     
     private void $$anonymous$$enu_HostGame()
     {
         //Buttons for Hosting
         if (GUI.Button(new Rect(10, 10, 200, 50), "Back"))
         {
             NavigateTo("main");
         }
         if (GUI.Button(new Rect(10, 60, 200, 50), "Start $$anonymous$$atch"))
         {
             
         }
         
         GUI.Label(new Rect(220, 10, 130, 30), "$$anonymous$$atch Name");
         $$anonymous$$atchName = GUI.TextField(new Rect(400, 10, 200, 30), $$anonymous$$atchName);
         
         GUI.Label(new Rect(220, 50, 130, 30), "$$anonymous$$atch Password");
         $$anonymous$$atchPassword = GUI.PasswordField(new Rect(400, 50, 200, 30), $$anonymous$$atchPassword, "*");
         
         GUI.Label(new Rect(220, 90, 130, 30), "$$anonymous$$atch $$anonymous$$ax Players");
         GUI.Label(new Rect(400, 90, 200, 30) $$anonymous$$atch$$anonymous$$axPlayers.ToString());
         $$anonymous$$atch$$anonymous$$axPlayers = $$anonymous$$athf.Clamp($$anonymous$$atch$$anonymous$$axPlayers, 8, 32);
         
         if (GUI.Button(new Rect(425, 90, 25, 30), "+"))
             $$anonymous$$atch$$anonymous$$axPlayers += 2;
         if (GUI.Button(new Rect(450, 90, 25, 30), "-"))
             $$anonymous$$atch$$anonymous$$axPlayers -= 2;
     }
     
         private void $$anonymous$$enu_Lobby()
     {
         
     }
 }

GUI.Label(new Rect(400, 90, 200, 30), $$anonymous$$atch$$anonymous$$axPlayers.ToString()); You just forgot the comma that's all. Hopefully that will help.

Which are the odds of another person (me) doing the exact same mistake (OnGui)? Thanks!
