Do unmet conditions reduce performance of loops?

I have a few "for each" loops, and I also have a condition to check whether or not a tween is still running. If the tween isn't running, would this improve performance, or does the game still have to check the "for each" loop? Is there a way of disabling loops when an instance of an object is no longer needed to be tested (in this case, I have for each loops to make play sound effects , but when the sprite isn't moving, it wont move any more, so the loop testing will no longer be necessary).

if you have something like this:

-check if tween runing

- then for each .. bla bla

it will not run the foreach loop if tween is not running.

if you have:

• for each ... bla bla

- if tween is running... then bla bla

then foreach will run every time, and you will check if tween is running multiple times.

i can provide more info if you show some kind of code / capx

Also, you can put your loops inside groups and enable/disable them when needed.

Groups or Boo

I'm actually wondering this, too (I still don't think this has been answered properly). I end up doing for each checks on things all the time and I certainly notice my CPU go up, but I'm never sure if that's really the cause.
