RE: FLASH: BUG or solution

WHat you need to do is to track the polarity of the variable in a separate

variable... the only time you want the actual variable to go negative is if

the polarity CHANGES... for example, if the object is supposed to go from

100 -> -20 then the scale will be negative, if it is supposed to go from -20

to -100 the scale will be POSITIVE.

Hi Jason -

Your sample was very informative - thanks for that - and I've seen this

before myself.


What I think is happening is that the value that you're using to scale the

movie clip is a negative. As an increment, a negative number times the

negative number equals a positive number. That's why we see the flip. The

next iteration/execution of the action then becomes negative again.


I agree that it is weird, and there are higher-level explanations for why

Flash does this, I am sure. I can try to give a few ways to work around it.


1. The best way to approach this in Flash is to not use a negative number

for the xscale value. Make sure your values don't go below zero.


(I may be wrong here, but what use would it be to have something scale

*below* zero percent? I can't think of any.)


2. Another way to work around this would be to use Set Property "_rotation"

to flip the movie clip 180 degrees, then apply the xscale with a positive

number.


Let me know if this helps, or if you need more.


Matt
