Loading a Map in ActionScript

[Matt Doyle]

Want to load an Unreal map straight from ActionScript? It's easy!

1. Add a CLIK Scrolling List (or Drop Down Menu) to the stage, and give it an instance name of 'maplist'.
2. Add a CLIK button to the stage, and give it an instance name of 'mapConfirmBtn'.
3. Add a new layer and name it 'actions'.
4. On the actions layer, enter this code:

import flash.external.ExternalInterface

maplist.dataProvider = ["DM-Deck","VCTF-Necropolis"];
var selectedMap:String;

Next, for a Scrolling List, use:

maplist.addEventListener("itemPress", this, "HandleItemClick");

OR - if you chose to use a drop down menu, use:

maplist.addEventListener("change", this, "HandleItemClick");

Now, add an event listener for the button.

mapConfirmBtn.addEventListener("press", this, "LoadLevel");

Then, create the map selection handler function:

function HandleItemClick(event:Object)
{
    // use this code for a Scrolling List
    trace("Scrolling List Selection: " + event.item);
    selectedMap = event.item;

    // or use this code for a drop down
    trace("Drop Down Selection: " + event.data);
    selectedMap = event.data;
}

Finally, add the function that will tell Unreal to load the level.

function LoadLevel()
{ 
    var command:String = "open ";
    command += selectedMap;
    trace(command);
    ExternalInterface.call("ConsoleCommand", command);
}

Save & Publish.
Import the SWF into UDK
In Kismet, you'll need to use OpenGFxMovie to play this movie in your menu level on a player spawn event.
Use your own custom menu class, or the standard GFxMoviePlayer class.

Works wonderfully, Thanks so much for this tutorial. I definitely think this should be a sticky.

Wouldn't a simple fscommand be much easier?

fscommand is for testing
