I’m having some trouble coming up with a solution for this situation and would really appreciate some advice:

I have a function gameTimerInterval() set to run every half second. Every x of those intervals (the value of x varies in this situation), it creates another interval that calls the function birdTimerInterval() every y of these new intervals. Basically, gameTimerInterval() determines when a new flock of birds will enter, and then birdTimerInterval() controls how each individual bird in the flock comes in (one at a time). The thing is, there can be multiple flocks coming on the stage at the same time, so birdTimerInterval() will need to receive a parameter so it knows which group of birds to control. The only way I could see achieving this is doing something like dynamically passing the name of the interval that’s calling the function, as I don’t know how I could use global variables or arrays to distinguish which flock should be moving. Any thoughts?
