i have 2 questions:
–1--
i have a 11 frame preloader animation that i want to advance one frame per 10% bytes loaded. (ie. if 10% loaded go to frame 2, if 20% loaded go to frame 3, etc.)
how do i split the bytes\_loaded into 10 chunks?
–2--
is it possible to have a preloader in an external m/c that plays the aforementioned animation in the main movie?
what i want to do is have a preloader animation playing on level 1 while the external mc is being loaded into level 0 behind a mask. is this possible?? or will i have to create the mask for every external mc ?
sounds confusing i know.
thanks for any help,
squish.

1. Use getBytesLoaded and getBytesTotal to calculate the percentage. Example (steping by 10%):
percentLoaded=Math.floor(\_root.getBytesLoaded()/\_root.getBytesTotal()\*10);
then use the value of percentLoaded to jump to each frame in the status bar
2. I normally place my preloader in a separate scene, or in frame 1 by itself. I haven’t tried loading things in at different levels.

thank you for the response.
it works except for a small glitch when loading the first 10% of the movie.
it seems to play through part of the preloader then it resets and its fine. do you have any idea why this happens?
is there a problem with the integer 0 and flash not having a frame 0?
i added a few frames at the end of the preloader that i would like to play through before moving onto scene two. i can’t get it to play through and move on to scene 2.
any ideas would be helpful
thanks again,

In the preloader, change the action in frame 1 from:
_bar.stop();_
to
_stop();_
One way to play your additional animation is to make the following changes to the preloader.
**Frame 1 actions:**
\*percentLoaded = Math.floor(\_root.getBytesLoaded()/\_root.getBytesTotal()_10);
bar.gotoAndStop(percentLoaded);_
**Frame 2 actions:**
_if (percentLoaded \<10) gotoAndPlay (1);
else {
stop();
bar.play();
}_
Place the following action in the bar movie clip at the last animation frame:
_\_root.play();_
