Re: [chuck-users] Begin the beguine

I'd like to point out that "count" is a variable name, not a built-in ChucK thing. In this example, "count" is just the name someone has chosen to keep track of a number that keeps increasing by 1. You might want to look at the ChucK tutorials I made for our Intro to Electronic Music course here at the University of Cincinnati. There are 7 tutorials that start from a simple SinOsc and introduce variables, functions, STK instruments, and sporking. They were intended as notes to accompany the class but they might be useful. I uploaded them here: https://github.com/jwmatthys/chuck-tutorials Joel On 09/30/2012 04:08 PM, Alberto Alassio wrote:

Ok, to me it wasn't so easy to understand count < steps. so it counts till the steps end, right? And in this patch count refers to steps but it is also the one who makes the freq increases by inc, I mean, for each count we have, then the freq increases. Is it correct? Thank you Kas, it always helps!

"count" refers to the current step. It starts out as zero and increases until the desired number of steps has been reached. "1 +=> count" adds one to the "count" and also stores the result back in "count".

It is not so clear to me why a float is used here for "count", instead of a integer, which would make more sense and enable us to simply increment by using;

count++;

Better yet would be a "for" loop. Maybe this example is deliberately doing unusual stuff to encourage people like you to spend some time picking it apart and figuring it out? It might also be very old and pre-dating something like comparing floats to integers. To me it looks like Ge's style which would make sense in both cases.

Hope that helps, Kas. _______________________________________________ chuck-users mailing list chuck-users@lists.cs.princeton.edu mailto:chuck-users@lists.cs.princeton.edu https://lists.cs.princeton.edu/mailman/listinfo/chuck-users
