Pink Pony

Pink Pony is a colorful tron-like 3D racing game with ponies and computer-controlled opponents, as well as multiplayer split-screen support for up to four people via keyboard or game controller.

Pink Pony can be played both on Linux and Windows and is both free and open source.

Visit the Pink Pony website for information on downloading and playing the game.

Hacking on Pink Pony

Compiling

You will need the following tools and libraries to build the game:

• SCons
• GLFW
• Imath
• DevIL
• protobuf (You also need protobuf-compiler on ubuntu)
• SDL_mixer
• FTGL
• libsigc++

Just build the game with scons in the current directory. If you have a dualcore CPU, you can use scons -j2 for parallel building.

Playing

To start the game, call ./Pony. ESC stops the game.

Installation

Pink Pony can be started directly in the source directory. If you want to install it in at a permanent location in the system, then you can use the files in the install directory for this.

The shell script pink-pony is a simple wrapper that checks if a config file is installed in the user's home directory and creates one if need be. It then starts the game with this config file.

The location of the game resource files can be configured in the pony.options config file. This way no patching of the source should be necessary.

Configuration (pony.options)

You can configure a lot of things in the game's config file, which is created in ~/.config/pony.options by default. You can supply an alternative config file as option in the ./Pony call.

Below is an example pony.options file.

Overriding game resources

The game's maps, models, textures, and sounds are loaded at runtime, so you may modify these files to create a custom experience. To do this, copy the game's resources directory from it's installed location to a new location and change the resource_dir property in pony.options. For example, on Ubuntu you can run the following command to copy the pink-pony directory into your home folder.

$ cp -r /usr/share/games/pink-pony/ ~/pink-pony

Then, you can set your pony.options like so. Replace <myuser> with your username!

resource_dir = "/home/<myuser>/pink-pony/";

From this point you can override the resource files.

Creating custom maps

Once you've taken the steps above to create your own game resources folder, you can create new maps by modifying the levels.xml file.

Maps are represented by a grayscale image, with black (#000000) being the lowest level of terrain and white (#FFFFFF) being the highest. See the images in levels/ for examples. Create a new image and place it in your levels/ directory and add a new <level> node to levels.xml containing the filename of your map image. Here's an example custom levels.xml file.

<levels>
  <level name="Flower Atoll"  file="levels/flower.png"  size="(1500 80 1500)" water_level="60"/>
  <level name="Flower"  file="levels/flower.png"  size="(1500 80 1500)" water_level="45"/>
  <level name="Lagoon"  file="levels/heart.png"   size="(1500 90 1500)" water_level="45"/>
  <level name="Heart"   file="levels/heart.png"   size="(1500 90 1500)" water_level="30"/>
  <level name="Ring"    file="levels/ring.png"    size="(1500 90 1500)" water_level="30"/>
  <level name="Long"    file="levels/long.png"    size="(1500 90 1500)" water_level="30"/>
  <level name="Strange" file="levels/strange.png" size="(1500 90 1500)" water_level="30"/>
  <!-- This one is the custom one! -->
  <level name="My Awesome Map!" file="levels/awesome.png" size="(1500 90 1500)" water_level="30"/>
</levels>
