Problem to use TMX maps into

[Clayton Verlique]

Hello guys...

I have a problem to use maps created in Tile Map Editor into HaxeFlixel... I heard that is good use TMX beacause u can put the collisions... but the flash still show ERROR.

This is my codes:

package;

import flixel.addons.editors.ogmo.FlxOgmoLoader;

import flixel.addons.editors.tiled.TiledMap;

import flixel.FlxCamera;

import flixel.FlxG;

import flixel.FlxObject;

import flixel.FlxSprite;

import flixel.FlxState;

import flixel.text.FlxText;

import flixel.ui.FlxButton;

import flixel.util.FlxColor;

import flixel.util.FlxMath;

import flixel.tile.FlxTilemap;

import haxe.io.Path;

import openfl.Assets;

/**

 * A FlxState which can be used for the actual gameplay.

 */

class PlayState extends FlxState

{

private var player:FlxSprite;

private var map:TiledLevel;

/**

* Function that is called up when to state is created to set it up. 

*/

override public function create():Void

{

super.create();

map = new TiledLevel("assets/Map/map.tmx");

add(map.floorTiles);

add(map.collideTiles);

add(map.overTiles);

//-----------------------------------------------------------------------------------------------------------------------

add(new FlxText(0, 0, 100, "Play State"));

FlxG.camera.bgColor = 0xFF0080FF;

//setCamera();

player = new Player(0, 0);

add(player);

}

function setCamera():Void

{

FlxG.camera.follow(player, FlxCamera.STYLE_PLATFORMER);

FlxG.camera.setBounds(0, 0, 0, 0, true);

}

/**

* Function that is called when this state is destroyed - you might want to 

* consider setting all objects this state uses to null to help garbage collection.

*/

override public function destroy():Void

{

super.destroy();

}

/**

* Function that is called once every frame.

*/

override public function update():Void

{

super.update();

}

}

And:

package;

go to TiledLevel.hx line 42 where it says

for ( tileLayer in layers )

and change it to:
for ( tileLayer in tiledLevel.layers )

It's possible there are other errors in your code, but this should get you partially there

Also read this tutorial (In English so you may have to figure it out on your own) :

[Clayton Verlique]

This line starting giving a error when I change..

source/TiledLevel.hx:43: characters 23-40 : You can't iterate on a Dynamic value, please specify Iterator or Iterable

I tried so many times that tutorial, but the errors keep coming :/

----------------------------------- EDITED ----------------------------------------

When I try follow that tutorial appears this error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Sorry I'm not an expert, however the tutorial works fine because I'm using that same code in my game.

I don't know what to say, other than do the tutorial from scratch in a completely new project, so you're not carrying any old bugs.

Once you enter it *as written* then try to get tha working, when you have that working then go back to your own code and figure out what you left out.

I realize you may have went through the tutorial, but I don't think you typed in everything he said in there because it does work.
