Using TMX loading in cocos.tiles (SVN Trunk)

[Balajee R.C]

I am loading a TMX file using the new TMX loading facility from trunk. Since I couldn't find any example on how to use the loader, I dug into the code and reckoned I had to do something like this:

class GameManager():

    """Game manager for Longsword. Entry point of all game synchronisation"""

    

    singletonInstance = None #Instance of game manager

    

    def __init__(self):

        #Initialise the cocos system

        cocos.director.director.init(width=640, height=512)

        #Create a scrolling map manager

        self.scrollingManager = cocos.tiles.ScrollingManager()

        #Load map resource from tmx file

        resource = cocos.tiles.load_tmx('radsLevelEdited.tmx')

        #Load each layer

        layerNames = ["grass","sky","cobbleStone","trees"]

        self.bgLayers = []

        for layerName in layerNames:

            layer = resource.get_resource(layerName)

            self.bgLayers.append(layer)

            self.scrollingManager.add(layer)

        

        #We have a blank layer in the tmx file called main

        #which we will use to add all our game entity sprites into

        self.mainLayer = resource.get_resource("main")

        self.scrollingManager.add(self.mainLayer)

        #Make sure that this layer receives input events

        self.mainLayer.is_event_handler = True

        #Create the main scene

        self.mainScene = cocos.scene.Scene(self.scrollingManager)

        #Create a list to store all entities in scene

        self.entityList = []

        #Create a collision manager to respond to collisions

        self.collisionManager = cocos.collision_model.CollisionManagerGrid(0, 1200, 0, 480, 128, 128)

        #Schedule updates at 16 fps on this manager

        self.mainLayer.schedule(self.update)

(You can find the above code at this code paste url for easier reading.) 

However I find some rendering artifacts at the edges of the tiles and messing up of the alpha layer at the edges. 

To see the problem, here is a screenshot of the tiled map as previewed in the Tiled map editor: 

And here is the image as seen in my Cocos2d application:

Could someone please point me as to what may be going wrong? Am I using the TMX loader correctly? I know I must be prepared for bugs when working with trunk but I am quite desperate as to my requirement to load TMX files. Please let me know if I am doing something wrong.

Try adding

do_not_scale=True

as a key-value parameter in the call to director.init

This instructs cocos to use the orthographic projection, which is better suited for tiling 

Other than that, I don't see any significative difference with the code in the cocos example at

http://code.google.com/p/los-cocos/source/browse/trunk/test/test_tmx.py

Thanks a ton, Claudio! Setting do_not_scale=True in director.init fixed the problem!
