[MX] Its a bug, but... ? (alpha fade thing)

programming flash

In my prior post about the alpha fade tutorial here (kirupa.com), where the pictures fade in and out as you press the arrows, it just dawned on me.

Why did the code work for this guys swf, yet EVEN THOUGH you guys and Macromedia say it is a bug… why didn’t the same code produce the same bug on this tutorials writers machine?

From my experience in programming - same code, same bug… but yes I know it is Flash. You would think it was much like a compiler since it is just using actionscript. Could have something to do with the .jpgs…

who knows, comments welcome.

Could you post a link to what you’re talking about? :slight_smile:

I just d/l, it works fine… (all his code and jpgs) but for my version I had to change it to the 95% max, 5% min to stop the final position jump.

I’m guessing it must be the jpgs.

there is a “bug” that causes that jitter/jump in images as Flash trys to approximate and calculate how and where an image’s pixels are shown on the screen. The effects of this bug dont lay in code alone, but also in position and size and other image aspects which determine how flash ‘percieves’ the image. The down and dirty of it all is that it CAN happen, and often does, so take the given steps to try to prevent it.
