An efficient scanline blitting algorithm

For the bitbox kernel, we need to have a fast graphical objects blitting library, since we will often have the same needs. Blitting from low Z to high Z of a fixed tiled background + overdrawing small sprites (to keep the 5k cycles budget) only goes so far, because as we are overdrawing pixels, we will be hitting the 5k cycles / lines pretty soon.

We will sum up the needs of such a library and propose an algorithm.

Tutorial : Creating a small game from scratch : game logic

Hello all !

In order to let people know about the process of making a game for bitbox (or a toy 2D Game in general, this post will have very few specifics to bitbox, next ones will be more involved) , I'll blog a few times to show you that in detail.

The game will consist in a bunch of people jumping out of a building on fire, and a team of two firemen who will make them bounce to the ambulance. It'll be programmed in C99, without any complex techniques.

Sounds familiar ?
