So I am using a FriendsofED flash book, and trying to transplant sections for my own game. I cannot even get what seems to be a simple portion of code to work.
So what I’m doing here is just setting up XML data as a static var, then having a function read and trace the output.
Here’s the XML sheet
package com.efg.games.zombiegame
{
public class TilesheetDataXML
{
public static var XMLData:XML=
<tilesheet>
<tile id="0" name="building" type="structure"></tile>
<tile id="1" name="building" type="structure"></tile>
<tile id="2" name="building" type="structure"></tile>
<tile id="3" name="building" type="structure"></tile>
<tile id="4" name="landscape" type="background"></tile>
<tile id="5" name="landscape" type="background"></tile>
<tile id="6" name="landscape" type="background"></tile>
<tile id="7" name="landscape" type="background"></tile>
</tilesheet>;
}
}
And, here is the class which is supposed to read it and trace out the arrays. I have copied it exactly to the original code(except for names), the original code works when I run it.
package com.efg.games.zombiegame
{
import flash.display.Sprite;
public class Main extends Sprite
{
public static const TILE_BUILDING:int = 0;
public static const TILE_LANDSCAPE:int = 1;
private var buildingFrames:Array;
private var landscapeFrames:Array;
private var tileSheetData:Array;
public function Main()
{
initTileSheetData();
trace("tileSheetData.length=" + tileSheetData.length);
trace("buildingFrames.length=" + buildingFrames.length);
trace("landscapeFrames.length=" + landscapeFrames.length);
}
private function initTileSheetData():void
{
buildingFrames = [];
landscapeFrames = [];
tileSheetData = [];
var numberToPush:int = 99;
var tileXML:XML = tileSheetDataXML.XMLData;
var numTiles:int = tileXML.tile.length();
for (var tileNum:int = 0; tileNum < numTiles; tileNum++)
{
if (String(tileXML.tile[tileNum].@type == "structure")
{
numberToPush = TILE_BUILDING;
buildingFrames.push(tileNum);
}
else if (String(tileXML.tile[tileNum].@type == "background")
{
numberToPush = TILE_LANDSCAPE;
landscapeFrames.push(tileNum);
}
}
tileSheetData.push(numberToPush);
}
}
}
I’m really stumped trying to figure this out, I don’t know what I’m changing that “breaks the chain”. I do not get ANY errors, there is simply no trace output. I tried copying the code then editing it, I tried writing it fresh, neither works. Here’s the original code(well sort of, the author did not provide the first iteration with only the XML data and InitTileSheetData function)
