Change background in openSpace map dynamically

[Madhav]

How to change the background of the openSpace map dynamically!!?
I have a openspace map who's background movieclip has got different frames (each with different bg's),

At first i have first frame bg, but how to change it to 2nd or other on button click???
Thanx...

Check the IOpenSpaceAPI.getBackgroundParts() method. It returns an Array2 (a matrix) containing a reference to all the sections of the current map's background (maybe just one in your case). You can access it and change the frame or what else.

hai Bax, thanx for reply...

may be a silly question, but can you explain how to access the background frames!!?
as you said, i got this-
var myBG : Array2 = openSpace.getBackgroundParts();

and my openspace map has got "myMapBG" movieclip which is having different frames with different backgrounds..

Are you using a single background movieclip, or did you split it in multiple parts?
In any case you can get each part like this:

Code: Select all

var bgParts:Array2 = openSpace.getBackgroundParts();
for (var r:int = 0; r < bgParts.height; r++)
{
	for (var c:int = 0; c < bgParts.width; c++)
	{
		var part:DisplayObject = bgParts.get(c, r) as DisplayObject
		
		if (part != null)
		{
			// YOUR CODE TO CHANGE THE DisplayObject FRAME (CHECK THE AS3 DOCUMENTATION)
		}
	}
}
