====== Icon based dialogues ======

Hi there.

thanks to the huge interest in doing Icon based dialogus in WME, I decided to create an universal simple object you can use and extend to suit your own needs.

Here's the example how to quickly implement it:

1. Create file scripts\dialogueObject.script with the following contents:
<code script>#include "scripts\base.inc"
 
 
// Define dimensions of your dialogue icons:
 
var ICON_WIDTH = 57;   
var ICON_HEIGHT = 57;
 
 
 
// the script here is the name where you will handle responses from player's click on the icon
 
method initializeDialogue(script)
{
    this.script = script;
    this.iconCount = 0;
    this.window = Game.LoadWindow("windows\dialogueWindow.window");
    
    var tmpwin = this.window;
    tmpwin.Visible = true;
    tmpwin.AttachScript(script);
    
}
 
 
// This will terminate the dialogue and free resources
 
method endDialogue()
{
    var tmpwindow = this.window;
    tmpwindow.DetachScript(this.script);
    tmpwindow.Close();    
}
 
 
// This will add icon to your dialogue window 
 
method insertIcon(name, sprite, hoversprite)
{
    var tmpwin = this.window;
    
    var tmpButton = tmpwin.CreateButton(name);
    
    tmpButton.X = this.iconCount * ICON_WIDTH;    
    
    tmpButton.SetImage(sprite);
    tmpButton.SetHoverImage(hoversprite);
 
    tmpButton.Visible = true;
    tmpButton.Interactive = true;
    tmpButton.ParentNotify = true;
    tmpButton.Disabled = false;
    tmpButton.PixelPerfect = false;
    tmpButton.Width = ICON_WIDTH;
    tmpButton.Height = ICON_HEIGHT;
    this[this.iconCount] = name; //We store the name for deleting fast reference
    this.iconCount = this.iconCount + 1;
}
 
// this will remove icon (usually after the topic is worn out)
 
method removeIcon(name)
{
    var tmpwin = this.window;
    var reorder = -1; // safe from nonsensical calls;
    for  (var a = 0; a<this.iconCount; a= a+1)
        if (this[a] == name)
            reorder = a;            
    
    if (reorder == -1)     return;
    tmpwin.DeleteButton(name);    
    for  (a  = reorder; a<this.iconCount; a = a +1)
    {
        this[a] = this[a+1];
        var button = tmpwin.GetControl(this[a+1]);
        button.X = a* ICON_WIDTH;        
    }
}</code>

2. create a file called scripts\reactions.script
<code script>on "first"
{
    Game.Msg("Do something after the first choice.");    
}
 
on "second"
{
    Game.Msg("Do something after the second choice.");    
}
 
on "third"
{
    Game.Msg("Do something after the third choice.");    
    dlgObject.removeIcon("second");
}</code>

3. put into scripts\base inc 

global dlgObject;

and into scripts\game.script
<code script>dlgObject = new Object("scripts\dialogueObject.script");</code>

Then in your test scene put the following code:
<code script>dlgObject.initializeDialogue("scripts\reactions.script");
dlgObject.insertIcon("first","icon.png","icon.png"); // insert some real image file instead of icon.png
dlgObject.insertIcon("second","icon.png","icon.png"); // insert some real image file instead of icon.png
dlgObject.insertIcon("third","icon.png","icon.png"); // insert some real image file instead of icon.png</code>

And the basic skeleton is set. Then after the dialogue is over, just call

**dlgObject.endDialogue()**; and probably **set Game.Interactive**? flag to true (if it was previously false)

Hope that helps, comments welcome!
