Drop down menus.

[Gadgethm]

Have you ever seen those drop down menus in Blockland?  Like the one on the 'Start a Game' screen that lets you choose the number of players.  I'm making a gui that will require one of those.  I need to know how to make the drop down part work.  I have the menu, but how do I fill it with choices?  Thanks.

Name it then dump its functions.

[Gadgethm]

I don't fully understand.  Could you give me an example?

Give it a name, and hit apply.
Open console, type in itsname.dump();
Find a function relevant for doing what you need.
Put it in the script.

I need to make it so that it will set a variable to different things depending on what the list is set to.
How would I do this?

Edit: Would I type add(name here)

Sort of. You would do PopUpName.add("String to be displayed",IntegerID,optionalIntegerScheme);
The optionalIntegerScheme will default to zero if you don't specify it.
Then assign a variable to it in the editor and just call upon that variable to check its selection. The value will be its IntegerID, I believe.
You can also assign a function for its "Command" and that will be called everytime you change its value.

So I make a function that will excecute a command if the variable equals certain things, or can I do that directly?  If so, how?

And also, it's not .add()
That adds an object to an object's group.

[Gadgethm]

Then what is it?

[lilboarder32]

My bad, its .addFront() with all the same arguments. Although .add() seemed to work, use .addFront().
You would assign a global variable to it, then check the variable. The value of the variable should be the value of the selections integerID. So, say you set the variable to $PopUpMenu. You could check it doing something like this:

Code: [Select]

function checkPopUp()
{
   switch($PopUpMenu)
   {
      case 0:
         //This is the "0" value within the menu
         //You can add functions within here
      case 1:
         //This is the "1" value within the menu
         //You can do the same in here
      case 2:
         //This is the "2" value within the menu
         //Same as before and you can do however many of these
   }
}

Or you can use it like this:

Code: [Select]

switch(%menu.getValue())
{
        case 0:
                "blah blah"
}

Trying...

Edit: It works!  Now, how would I get rid of one option?

I think its .remove(integerID);  but just dump its functions and look for some remove function.
