I got back into hacking around with C while my classmates were learning how to make breakout in JavaScript, so I decided to give this a shot. My goal is to make the entire thing in less than 1,000 LOC and only rely on SDL2.
A,D and left/right arrow keys controls the paddle. Q quits the game.
If cheating is enabled (check config.h), clicking will position the ball
to the mouse pointer, and W simulates winning the game.
Make commands include all (default), clean, install, and
uninstall.
config.mk stores common settings for customizing building the
program. I've set CC to clang, but you might set it as something
else if you don't like clang.
PREFIX is set to be ~/.local. For global installation, set it to
/usr/local.
Common variables and settings are stored in config.h. I really like
this file, so please treat it well :).
The code has four-space indents (no tabs!), curly braces in function definitions have their own line, and any code block less significant doesn't. Line width is ideally at 80 cols, but I break the rule depending on how awkward the line of code is.
