I am currently following Ray's tutorial on cocos2d-x tile map and my very simple code is not working at all.
So here is my code,
_tileMap = TMXTiledMap::create("TileMap.tmx");
this->addChild(_tileMap);
and according to the debugger, _tileMap is null, which causes a crash on the addChild method.
Do anyone have any idea why this is happening?
p.s _tileMap is declared as a TMXTiledMap* in header, TileMap.tmx is totally filled with stuff and TileMap.tmx along with other things are imported into the resource folder using creating folder reference.
Have you try "Tile layer format" with "Base64(uncompressed) ?
I have same symptom as like you, but I get out from stock by change tile layer format from cvs to Base64(uncompressed).

I've got a customised instance of GraphEditor in a view in an ASP.NET MVC app and I've got it set to use a database for diagram persistence. When opening, I've programmed it to create a new model to initialise the graph using the model data stored in the database. This works, except that vertexes and edges that were black and white when saved become blue when loaded. I'm guessing there's some default mxGraph style variable that's responsible for this, but I'm not sure. Anyone have any ideas? Thanks!
So, in case it's useful to anyone else, I actually found the solution. The default colours are defined in mxClient as hexadecimals and can be replaced with whatever you want to use.
I'm using cocos2d-x 3.17. When I run a Follow action on a sprite, the tiled map can't render fully. The map looks exactly the same as the screen record shows in posts below
https://discuss.cocos2d-x.org/t/1-5b2-tiled-map-not-rendered-fully/36661
https://discuss.cocos2d-x.org/t/solved-tilemap-rotation-clipping/37114
But they were using Cocos Creator and can fix it by setting ENABLE_TILEDMAP_CULLING = false.
Is there any equivalent settings in C++ api?
Found out the root cause is that the Scene has been moved by Follow action. It seems in cocos2d-x, Scene is not supposed to move.
I am new to Lua scripting, and game development. So please I am just a noob in Lua.
I have searched the net for solutions to my problems, without any luck.
I use Photoshop, Corona, Dusk, json and Tiled on windows7.
I am creating a "board" like game, i.e. Setlers. I am using a world map, as the background. The background image of the game area is a world map (world.png file). I have no problem here.
I would like to create transparrent clickable objects matching the countrys borders on my gamemap with all parameters and values (I have added in Tiled) stored in the object. So When the player clicks on the country the transparrent object (on top of the map) is the one clicked and an eventlistener acts on the click.
In Tiled I can create all the objects I need, naming them + assigning parameters and other values.
If I add object.alpha value in Tiled, the alpha value is passed on to corona and working there.
How can I read these data from the json/tmx file in Corona and adding them to a lua table?
The way I am thinking to use the Tiled map and its objects, is to create one polyline trace of each country’s border (creating one object per country). Then place each “country traced object” on top of the world.png map, also naming the object with the countrys name like “object.name = TileBritannia” and also the other properties for use in game.
My problem is getting the objects info, like object.name, and an eventlistener reacting to a click on the object.
Is a polyline the right way to create a clickable area on a map, when I use a png file as a background image?
What is the best way to create a country border objects, in one layer or with all countries as individual object layers in Tiled.
Can I create one layer with sub objects and still access them in my code?
How do I get the object name and other properties, set in Tiled.
When I try to use the (local britannia = tiledMap:load("britannia.json")) the "load" is not working, getting a nil value.
I am looking for a code that will extract/get/read the object.name i.e. “objBritannia” or "TileBritannia". from the json/tmx file.
When I try to read the different parameters from the json file, I don't get the result I expect. I get the result = function: 046A73B0, was hoping for an object name of some sort.
Please provide links to or code example.
I have edited the question.
Thanks
For questions 1 and 2: I have not used Tiled, but based on Corona Tiled, you have the right strategy in mind. That page makes me think that you can just use tap event listener to detect tap. If you are having issues with the example on that web page, please update your question to be more specific. If tap event handling doesn't work (maybe you're talking about a different Tiled lib), look a Polygon fill and Point in Polygon detection, because that's basically what you need to do. Try some stuff from there. If it still doesn't work for you, then update your question with specifics otherwise it will be likely get closed (it is a little too broad as it is).
For #3, Lua is a dynamic language that supports adding properties to objects in one line. So upon the example on the Corona Tiled page, all you would have to do is
tiledMap = require("tiled")
local britannia = tiledMap:load("britannia.json")
britannia.name = "Britannnia"
local Zulu = tiledMap:load("zulu.json")
zulu.name = "zulu"
Naturally you will probably have a whole bunch so you will create a function that you call for each tile. It's not clear what map.layer["objBritannia "].nameIs("TileBritannia") is supposed to do so I can't comment.
I am building an app using Starling and have imported the scaffold project however whenever I call getTextureAtlas() it doesn't show the image
this.mLogo = new Image(Assets.getAtlasTexture("powered_by_starling"));
this.mLogo.x = 0;
this.mLogo.y = 0;
this.addChild(this.mLogo);
There are no errors so I am guessing it can find the texture. If I change the name to something that doesn't exist it throws an error 'texture cannot be null'. I am also using
Assets.contentScaleFactor = Starling.current.contentScaleFactor;
and everything is pretty much a standard import of the scaffold as is however I am using Feathers UI screen navigator but I haven't had a blank image issue on other projects.
Edit: I can't seem to get the sprite to work within a class that extends feathers.controls.Screen
Is getAtlasTexture a function that you wrote? Are you using starlings asset manager? If that's the case, you will need a instance of that class, not static method call.
Anyway, try using the Texture class and the static method it offers. You don't need atlas(sprite sheet) for a Image - you will need it however for MovieClip.
Texture.fromBitmap
Texture.fromBitmapData
.... and others, check documentation
If your graphics are embedded, then use this:
var _img:Image = new Image(Texture.fromBitmap(new Assets.EmbeddedGraphic()));
Are you using atf? because the same happened to me until I used png and then it worked
I'm looking for a list of flash.include.whatever.whatever for as3.
If no one knows a list then can someone tell me the flash.include to use for drawing rectangle with the startFill and endFill things? Thanks for any help.
I didn't find anything on either of these googling, and the place I got the code for drawing a rectangle of course didn't have the flash.includes included in the example code... is their a reason so many people do that? Any way I can get around it?
Do you mean you want a list of the packages and classes that come with AS3? That is typically called the documentation and can be found here:
Adobe ActionScript® 3 API Reference
For drawing a Rectangle, you can start at flash.display.Shape. It has a graphics object with the methods .beginFill() and .endFill().
you can using a Graphics.
The Graphics class contains a set of methods that you can use to
create a vector shape. Display objects that support drawing include
Sprite and Shape objects. Each of these classes includes a graphics
property that is a Graphics object. The following are among those
helper functions provided for ease of use: drawRect(),
drawRoundRect(), drawCircle(), and drawEllipse(). You cannot create a
Graphics object directly from ActionScript code. If you call new
Graphics(), an exception is thrown.
The Graphics class is final; it cannot be subclassed.
here is a sample
import flash.display.*;
this.graphics.beginFill(0xff0000);
this.graphics.drawRect(0,0,100,100);
here is a Adobe Tutorial
AS3 all display class list here
You do not necessarily need to default AS3 include. fine compile. But include only the code you can see the hint. perhaps, CS4 after that if you use a specific class will automatically include. or ctrl+space is autocompletion.
As follows by default when you install the flash is because of the SWC path.
As per I know, there is not such a thing like Flash.include. May be you're trying to ask something else or may be i am still unknown about this feature.
If you found any positive thing about this, please let me know, i want to know that new thing.
