Perfectly demonstrate what Macromedia are up to with 8 - making Flash easily do what Applets used to do, plus a few things Photoshop does.
That's not a complaint; I'll be upgrading, but mainly because of video and especially the Alpha channel - lotta fun there!
This isn't mind-bending or anything... I just took my old Particle Smoke experiment and added Flash 8 blending modes to see how the frame rate held up. Flash 8 player is pretty robust!
The left side buttons let you set each available blend mode.
1 = no effect, 8 = Additive, 9 = Subtractive
The lower right buttons let you choose different images to use as the "particle":
1 = a shaded, three dimensional looking puff of smoke.
2 = a dark puff with no shading.
3 = a white puff with no shading.
4 = some guy's face
5 = a multi-colored vector star.
The slider bar sets the alpha transparency.
Ideally this effect looks most realistic with puff style #1 and 10-20% transparency, and rotation. Unfortunately I had to disable rotation because the frame rate takes too much of a hit with it on.
OH AND BY THE WAY... You can click and drag the smoke emitter around!!
Now this is the stuff I'm looking for. Are there ANY tutorials out there on how to use filters for doing this stuff? the docs have some very limited info on the full capabilities, and that's pretty disapointing.
I think google will help you alot if you are just beginning AS coding. If you are already familiar with it then the best resource is the included Help files in Flash 8.
