Re: [pygame] Timing question (newbie)
Hi again, I've been checking the suggestions and they are all very informative, but I am still somewhat stuck. I was a bit unclear formulating my question - but thanks anyway for your previous answers. Ok, so what I want to do is: make pygame play a song, and while it is playing, record my keystrokes (so instead of having a program deciding what to press when, I will do it). Then I want to be able to playback my keypresses so the player has to be repeat them when playing. So I guess I am aiming at some kind of level editor for rhythm games, maybe? But looking at your examples, I have another doubt: what if I want to tie specific input to a specific event in the game, and measure how precise that input was, to give points? For example, I trigger an animation based on random numbers - that animation has a number of stages: depending on which stage the player provides the required input, they are rewarded with points. Does this make any sense? (I am thinking typing-rhythm games here, of course :) Sorry for being a pest, and thanks for the help!

That's great people, thanks a lot!!

The idea is that the player has to press a key within a specific time, getting more points the better the timing. And I have little idea how to do it. I am thinking creating uservents, and the matching them to key input, but I am a bit clueless about the timing thing. Any help is welcome! Have a look at PyDance: http://icculus.org/pyddr/ It's GPL so you can look under the hood. Frets on Fire and StepMania are both open-source too. I believe at least parts of frets on fire are Python, but I'm pretty sure StepMania isn't. FoF is a guitar hero simulator, by the way.

Re: [pygame] Timing question (newbie)
I've attached some very rough, proof of concept code I wrote for my students. It wants 2 command line arguments. The first is a sound file (mp3 or wav). The second has the times in seconds at which beats occur. I generated mine with aubiotrack. You feed it a wav file and it prints out times of the detected beat. The program draws a little graph showing how close your key, mouse, or ddr pad presses are to the beat. Very rough. It was just a test to see if this was even possible. I've got a team of students working on an accessible version of DDR for kids who are blind. They'll do a better job I'm sure. gb Miguel Sicart wrote: Hi all, I have a question about timing - I want to make a little game based on rhythm input, a bit like dance dance revolution, patapon, or similar.

[pygame] Timing question (newbie)
Hi all, I have a question about timing - I want to make a little game based on rhythm input, a bit like dance dance revolution, patapon, or similar. The idea is that the player has to press a key within a specific time, getting more points the better the timing. And I have little idea how to do it. I am thinking creating uservents, and the matching them to key input, but I am a bit clueless about the timing thing. Any help is welcome! Thanks a bunch! M
