Hey everyone, im sorry if i bug you with all my questions. I am very interested in robotc and want to learn as much as possible.
My question for today is;
What is a way to run two things at once. I have my program that is the important part with all the functions and acions and stuff, I also want to run a second program that make the nxt beep out music by playing timed beeps at different frequencies. I have all the code but i dont know how to integrate them. I need to be able to drive and do everything else while the nxt plays music. I have to make it so the music doesnt effect the main task at all; but i also want the music to play and if it switched tasks or something the timeing would be off. I need to like run the music in the bacground but have it not effect the code. Any suggestions, also when i get the code done i will post it on here so everyone can see
Thanks

I'm sure that you're not bugging anyone with questions. After all, that's what these forums are here for. If you want an introductory tutorial in multitasking, you may want to look at this compilation in the VEX forums: http://www.vexforum.com/showthread.php?t=53551

I seldom play with the NXT tone functions except for playing warning sounds. But if I remember it correctly, the PlayTone function in RobotC will queue up the tones to be played. I don't have RobotC in front of me at the moment so I can't verify it. In theory, you can just execute the PlayTone functions one after the other so they will be queued up and executed in a timely manner. Having said that, I don't know how big is the RobotC tone queue. If you play a long song, it may overflow the queue. On the other hand, it is not really that difficult to write a task to play songs in the background. For example:

EDIT: Thanks Xander, I have corrected the bSoundActive variable.

It's bSoundActive and it's a boolean variable
