Hey everyone,
I'm interested in distorting movie clips at runtime based on user input. I know how to rotate - thats easy : clip._rotation is a number from 0 to 360. I know how to scale - thats easy too : clip._xscale and clip._yscale are conveniently independent. But how do you SKEW a movie clip at runtime??
The best I can come up with is really complicated. If you put a symbol within a symbol and name both ( something like shell and core ), you can squish and rotate them independently, making it possible to distort the clip twice as many ways.
shell.core._yscale = 160;
shell.core._xscale = 100;
shell.core._rotation = 45;
shell._yscale = 40;
shell._xscale = 100;
shell._rotation = -22.5;
this gives me somewhat the effect i want, but it is not precise, and i want to be able to skew at any angle, not just 45 degrees.
What is the trigonometry behind this? Any math wizzes want to give me a hand?
Thanks!
