Virtual Function Equivalent in Haxe + NME

Public virtual function is not an expected function definition in HaXe. Researching results...

Flixel HaXe + NME FlxSprite Loading in iPad

AS3 embed style uses custom class ddeclarations and the Assets getbitmapdata for cross compatability:



class TestClass extends Bitmap
{
    public function new() { super(Assets.getBitmapData("assets/map/ArmyGrid.png")); }
}

    class GenericGrid
    {

public static var Test:Class<Bitmap> = TestClass;

        public function new()
        {   
            t = new FlxSprite(0, 215, Test);   
            t.x = FlxG.width / 2 - t.width / 2;
            t.updateTileSheet();
            parentState.add(t);


OR!

Loadgraphic seems to work also on direct names on ipad so far:


/* test: succeeded, this works
        t = new FlxSprite(0, 0);
        t.loadGraphic("assets/map/ArmyGrid.png", false, false);
        t.updateTileSheet();
        t.x = FlxG.width / 2 - t.width / 2;
        t.y += 200;
        parentState.add(t);
*/

Running Haxer the AS3 to HaXe Converter in Java

Go into src and compile with Javac -d . net/interaxia/haxer/Haxer.java

Then run java net.interaxia.haxer.Haxer:

java net.interaxia.haxer.Haxer "/Users/beastadmin/Documents/Backup/src" "/Users/beastadmin/Documents/Atmospherian-Haxer-455fc86/src/convert/"

I got an error that traced back to reading the package name to save the files so I changed that and recompiled:

Exception in thread "main" java.lang.NullPointerException
    at net.interaxia.haxer.Haxer.saveOutputFile(Haxer.java:49)
    at net.interaxia.haxer.Haxer.main(Haxer.java:41)

//Line 48 below...
private static void saveOutputFile(String rootFolder, HaxeFile file) {
        String destinationPath = rootFolder; //Change here @ Line 49 to this
        //...
}
//...

IPad Landscape Orientation on HaXe NME

When using landscape orientation in the nmml file for an nme project targetting iPad there is a problem where lib.current.stage.stageheight and stagewidth are still referring to portrait coordinates.

To fix this add an if statement to swap the two values before you use them.

Talk from the NME author in a thread: "It seems that if you target iOS 3.2, you can submit with armv6, but if you target iOS 4 or 5 (not sure about 4... definitely 5) the App Store will reject your application if it lacks armv7."

HaXe NME FlxTilemapExt Usage in Beebles HaxeFlixel Port

 This bit of knowledge was not available on Google but to use the sloped tiles in Flixel ported to HaXe (+NME) then for some insane reason you have to call something that's seems fairly default.

The function setSlopes has to be called on the flxtilemapext after creation with four arrays as inputs. I used [2],[3],[4],[5] as my first guess and everything seams alright thus far.

This should save anyone else some time who is attempting cross-platform Flixel games.
