Open gui if player clicks on button

Questions & Answers

i want to open another gui if the player clicks a gui button.

so .. if the player clicks on my third button it should open/enable a new gui window

this is my code so far

function OnGUI () { // Make a background box GUI.Box (Rect (10,10,100,120), "Menu");

// Button 1: Make the first button. If it is pressed, Application.Loadlevel (1) will be executed if (GUI.Button (Rect (20,40,80,20), "Restart")) { Application.LoadLevel ("Level 1"); }

// Button 2: Make the second button. if (GUI.Button (Rect (20,70,80,20), "Main Menu")) { Application.LoadLevel ("Level 2"); }

//Button 3: make third button here should be the button to make a new gui??? if (GUI.Button (Rect (20,100,80,20), "Info")) {

} }

should a make a new script with the new gui i want to activatie, and activatie/enable it if player clicks on button 3 somehow?

or is there a much easier way?

Just got the code from nicholas on the unity forums:

Code:

var showMoreGui = false; 

function OnGUI () { 
    if (GUI.Button (Rect (10,10,100,20), "Show More")) 
        showMoreGui = true; 

    if (showMoreGui) { 
        GUI.Button (Rect (10, 40,100,20), "Hello there"); 
        if (GUI.Button (Rect (10, 70,100,20), "Close")) 
            showMoreGui = false; 
    } 
} 

To seperate it out a bit, you could do: 
Code:

var showMoreGui = false; 

function OnGUI () { 
    if (GUI.Button (Rect (10,10,100,20), "Show More")) 
        showMoreGui = true; 

    if (showMoreGui) 
        ExtraGUI (); 
} 

function ExtraGUI () { 
    GUI.Button (Rect (10, 40,100,20), "Hello there"); 
    if (GUI.Button (Rect (10, 70,100,20), "Close")) 
        showMoreGui = false; 
} 

Whether you want to split out this more GUI or do it like this generally depends on the complexity. I usually start with just having it inline, then move it to a separate function before completely splitting it out.

Depending on the complexity of your GUI it might be a good idea to have several GUI scripts, that get switched. However what I tend to do on non-complex GUI's is this:

int menuNumber = 0;

void OnGUI()
{
  switch(menuNumber)
  {
    case 0:
      DisplayMainMenu();
      break;
    case 1:
      DisplayOtherMenu();
      break;
    default:
      break;
}

void DisplayMainMenu()
{
  if (GUI.Button(rect, "Change Menu"))
    menuNumber = 1;
}

void DisplayOtherMenu()
{
  if (GUI.Button(rect, "Change Menu"))
    menuNumber = 0;
}

I hope this gives you an idea.
