mmm, it was just a little equation that told you, based on the sprites anim. speed and length, how many frames would pass for the animation to cycle once. like, for exanmple, i used it to figure out how long to make hte delay in a path for an explosion animation so that it would delete itsself at the end of the path, which would be hte same frame as teh end of the animation (before it looped).
it used to be on one of your documentations in sourceforge, but i havent been able to find it.
