When all is done, you may choose to export in. Duplicate padding and edge padding functions are also usable, as well as aliases, which work to get rid of jagged texture edges.

You can add padding to your textures to smoothen them out, and you can also increase or decrease their quality to save space. You can also change the min and mag filter, as well as the minimum and maximum page dimensions. RGBA88, LuminanceAlpha, and more such encoders are among the options.

To test it out, we loaded in the sample textures from the test-me! folder that came in the archive, and started modifying the pack's settings.Ī bunch of the textures' properties can be changed in the Settings menu: for one, you can start by changing their encoding, where plenty of formats are available. jar extension and works on its own, without requiring any additional config files or anything of the sort. When it comes to setting up the tool, there isn't much to be done other than unpacking the archive, then starting it up. Distributions of libGDX come with texture packers, and if you're on the lookout for a GUI for such a thing, the GDX Texture Packer provides a much-needed interface to help users better manage their projects. LibGDX is one such platform, and it grants users the possibility to create cross-platform games, thanks to its streamlined environment. Open-source and free-to-use game development frameworks have been surfacing over the last few years, granting developers more opportunities to create new games. If you want to continue from this point, you can take the variables from main and create a Sprite class and/or Animation class.There's a lot to work on when it comes to game development, and designing and managing textures numbers among them. With any look your header file for TextureAtlas will look something like this: #ifndef TEXTURE_ATLAS_HĬlass TextureAtlas Voila. The class does NOT have a default constructor. Note that the constructor takes a string (path to the json file) and a pointer to an SDL_Renderer (for texture loading).

We’ll use this to load our texture and keep that code away from our json parsing code.

loadTexture(), which takes a string and a pointer to an SDL_Renderer.

getTexture(), which returns a pointer to the texture.

operator, which takes a string and returns an SDL_Rect pointer.

With a little foresight, we’re also going to declare three methods in addition to the constructor and destructor, they are: Next step is to include SDL in your source file, like so: #include Īnd then write your main() and initialize SDL: if ( SDL_Init ( SDL_INIT_VIDEO )) (for reading the file) and json/json.h (for parsing the json, duh!). If you’re using Visual Studio like me, you’ll need to open up your project properties, go to VC++ Directories and add the path to your sdl includes and libraries in the appropriate files (detailed info on that here). It spits out xml files but there are plenty of online converters).įirst off, you’ll want to write your main.cpp and set up SDL in your application.

A json file that points to the packed texture and defines the subtextures (I’m using Shoebox to pack the textures, which depends on Adobe Air.

Jsoncpp (to generate the source files, just run amalgamate.py from the repo, the files can then be found in the dist folder).

The SDL Image library ( Direct download).

SDL (if you don’t know SDL, but want to, there are plenty of helpful tutorials here).

Though this is a reasonably simple procedure, there are some prerequisites: In this tutorial I will walk you through animating a sprite with a texture packer.
