Hey all, I just took an advanced actionscript class and basically learned the finer aspects of math tweens.

However, my teacher was kind of an actionscript “zealot” and said he uses math tweens for everything (I don’t find them easier to do like he does- I’m more visual than theoretical). My question is this…

are actionscript tweens less CPU intensive? do they create much smaller file size?

What are the “real world” advantages of math tweens versus frame tweens? And in which applications would you use them???

THANKS ALL!!
