As of right now, this is a very simple rhythm test program built on SDL. I've done quite a bit of tweaking to make this a solid baseline to build more complicated rhythm games on.
To build this program all you need do is run make in the root
directory of the project. The binary will be created as target/game.
As of now, the program accepts different command-line arguments:
-bpm <f32>: the number of beats per minute the game should play at (default: 120).-prox <i32>: the number of milliseconds before and after the beat that you'd like the screen to flash to indicate a beat (default: 30).-draw: whether or not to draw a graph of your progress.-met: whether you would like a sound to play on each beat. The following options modify this behavior:-metp: path for the file to play as a metronome (default:assets/metronome.wav).-metant <i32>:SDL_mixerruns audio with a slight delay. This argument controls how many milliseconds before the beat the program should queue the sound to play. In testing my own rhythm, anywhere from 15ms to 25ms has made me more accurate (default: 0).
-mus: whether you would like to play a music file. The folowing options modify this behavior:-musp <str>: the path to the file to play (default:assets/music.mp3(you'll have to create that yourself)).-musd <i32>: how many milliseconds to wait before starting the music (default: 0).
-pat <str>: a sequence of1and0characters indicating when a beat is to be shown. If-metis set, the program will only play sounds on those beats.
While you're in the game itself, Escape will cause the program to
exit, Space will toggle a graph of how close you were to the correct
beat, and every other key will count as a beat in the test.
