How to have a GUI Texture pop up after clicking a button?

I’m trying to find out how to get a clipboard to appear when I click a button. I have the clipboard texture as a GUI Texture, and it’s on the screen when the game is playing. How do I hide it until I press the button (which is one of the Unity default buttons), and then have it hide?

#pragma strict
// JavaScript
var icon : Texture2D;// Defines icon textures
var icon1 : Texture2D;// Defines icon textures
var icon2 : Texture2D;// Defines icon textures
var icon3 : Texture2D;// Defines icon textures
var icon4 : Texture2D;// Defines icon textures;
 
function OnGUI () {
    GUI.Button (Rect (10,10,100,21), GUIContent ("Tools", icon, "Open tools"));// Makes Tools button
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    GUI.Button (Rect (115,10,100,21), GUIContent ("Chart", icon1, "View patient's chart"));//Makes Chart button
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    GUI.Button (Rect (220,10,100,21), GUIContent ("Interact", icon2, "Interact with patient"));
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    if (GUI.Button (Rect (10,700,120,21), GUIContent ("End Simulation", icon3, "Quit")))// Makes Quit button
       Application.Quit();// Quits simulation if button is pressed
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    GUI.Button (Rect (325,10,100,21), GUIContent ("Help", icon4, "Get some help"));// Makes Help Button
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
 
 
}

I would want the button that says “Chart” to display the picture.

Do you have a bit of source code for us to help with? The short version is to add a boolean that is toggled when the user clicks a button. Then, when OnGUI iterates and sees that boolean is true, it will be render the clipboard texture.

Yeah. I put the buttons in their own scripts. Here's the one for the chart. #pragma strict var icon1 : Texture2D; function OnGUI () { GUI.Button (Rect (115,10,100,21), GUIContent ("Information", icon1, "View patient's chart"));//Makes Chart button GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does }

 –

if(GUI.Button (Rect (115,10,100,21), GUIContent ("Information", icon1, "View patient's chart"));//Makes Chart button){ showToolTip=true; } if(showToolTip){ GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does } And to hide in in the future you can start a coroutine witch would turn the showToolTip false, but this will render your button useless or at least you will only know what does it do when you already clicked it.

 –

There's a compiler error saying that showToolTip is an unknown identifier.

Yeah you need declare that :P if you are using csharp then private bool showToolTip = false; OR if Javascript: private var showToolTip : boolean = false;

K, now I get what you want, this is the full script you need to implement:

private var showToolTip : boolean = false;
public var yourTexture: Texture;
function OnGUI () {
  if(GUI.Button (Rect (115,20,100,21), GUIContent ("Information", icon1, "View patient's chart"));//Makes Chart button){
    showToolTip=true;
  }
  if(showToolTip){
    GUI.DrawTexture(Rect(115,0,100,20), yourTexture);//this will draw a texture above your button
  }
}

Attach this script to an empty game object and drag your texture to the Your Texture slot in the inspector window

Edit: Implemented in your script:

    #pragma strict
    // JavaScript
    var icon : Texture2D;// Defines icon textures
    var icon1 : Texture2D;// Defines icon textures
    var icon2 : Texture2D;// Defines icon textures
    var icon3 : Texture2D;// Defines icon textures
    var icon4 : Texture2D;// Defines icon textures;

    private var showToolTip : boolean = false;
    public var yourTexture: Texture;

    function OnGUI () {
    GUI.Button (Rect (10,10,100,21), GUIContent ("Tools", icon, "Open tools"));// Makes Tools button
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    if(GUI.Button (Rect (115,10,100,21), GUIContent ("Chart", icon1, "View patient's chart"))){
          showToolTip=!showToolTip;
      }
 if(showToolTip){
    GUI.DrawTexture(Rect(115,0,100,20), yourTexture);//this will draw a texture above your button
  }
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    GUI.Button (Rect (220,10,100,21), GUIContent ("Interact", icon2, "Interact with patient"));
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    if (GUI.Button (Rect (10,700,120,21), GUIContent ("End Simulation", icon3, "Quit")))// Makes Quit button
    Application.Quit();// Quits simulation if button is pressed
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
    GUI.Button (Rect (325,10,100,21), GUIContent ("Help", icon4, "Get some help"));// Makes Help Button
    GUI.Label (Rect (10,40,100,35), GUI.tooltip);// Shows description of what button does
     
     
    }

Alright, looks good so far! Thanks, and have a nice day!

You're welcome :) But an accept answer wouldn't hurt if this solved the problem, so others would know it's answered. (A thumbs up wouldn't hurt but that's not necessary :D)
