This is a guide for people willing to develop Rockbot in several platforms.
- Qt Creator 2.0 beta1 or later: http://qt.nokia.com/developer/qt-qtcreator-prerelease
In Ubuntu, just type:
- sudo apt-get install build-essential libsdl1.2debian libsdl1.2debian-dev libsdl-image1.2 libsdl-image1.2-dev libsdl-mixer1.2 libsdl-mixer1.2-dev libsdl-ttf2.0-0 libsdl-ttf2.0-dev
Ubuntu normally ships with an old version of Qt Creator, download the newest from http://qt.digia.com/ and install it from terminal:
- chmod +x qt-creator-linux-x86-opensource-2.0.0-beta1.bin
Download source from this site, or from svn: https://svn.code.sf.net/p/rockbot-game/code/v1.
Now run Qt Creator and open the cpp_rockbot.pro file inside the rockbot (v1) folder you created, then the Rockbot_Editor.pro in editor folder, click on project button, check and change it to build folder or copy the build/data folder to where project is configured to be built into.
The qmake project cpp_rockbot.pro, contains a section with CONFIG flags to build for several platforms, if your computer have the corresponding SDK installed on it, just uncomment the desired one and comment out all the rest, run qmake again on the IDE and rebuild to have binaries for other systems.

Each tile (part that composes the tileset, used to render the background) have a size of 16×16 pixels.
A boss or stage enemy can have any width, but height must be multiple of 16 (16, 32, 48, etc)
The image files are in PNG format (with the given palette).
There is no need to separate parts for the sprites, we are using complete animation frames (each frame is the whole picture).
Boss/players faces are of size 32×32 pixels.
Some examples and a reference to our palette (in RBG). Please note that the last 3 colors are used for effects of color-cycling.
