is if faster to have a group closed or open, even if the group is completely unused at the time.
say if i had a group dealing with moving platforms, then all the platforms were destroyed, would mmf2 still spend some time, if only a little, checking through the events?
If you mean in runtime, I'm assuming that closed (disabled) groups are automatically jumped over, because theres no reason for MMF2 to check them all, making the loop shorter. This would be efficient, whether or not it actually does it though, I'm not sure. I'm not sure how I'd go about testing this.
I've shut off unused groups in Tormi and it's seen a minor memory decrease. Like 1mb. Soon as they're open it all changes, and shutting them again doesn't get that 1mb back. Could be my coding. Yea.
I was referring to loops, which in large quantities, does in fact have an effect on frame rate. A good example of this would be running a fast loop 10000 times. That event takes longer to accomplish, so the loop is made larger. Frame rate loss is not always the result of graphics, it's much more broad then that.
