SWF It Good

So the other day I spent 2hrs looking for how to and trying to do an alpha mask (I’ve done on once). So like an idiot I was trying to do it the Photoshop way with level of gray.

My method of thinking

• Black = 100 and White = 0
• but it doesn’t matter what color only the opacity.

If you have never mad a alpha mask in Flash before or CS3 it’s easy.

1. open a fla
2. draw a shape
3. Make that shape a MovieClip
4. name it maskee_mc
5. draw a second shape
6. use a linear gradient
7. choose color
8. set one linear color alpha at say, 40
9. Make that second shape another MovieCilp
10. name it mask_mc

[as]

this.mask_mc.cacheAsBitmap = true;
this.maskee_mc.cacheAsBitmap = true;
// as2 was maskee_mc.mask(mask_mc);
maskee_mc.mask = mask_mc;

[/as]
That’s it!
