in one movie, AFTER publishing my swf file, the tweens randomly stop at different points within each run of that same file.

in another movie, the swf file runs consistently, and the bug gets introduced BEFORE publishing the swf file. if i select and then deselect a shape (without performing any other action besides selecting and deselecting onscreen), then publish the file, it will stop at a different point than in the last swf file i exported.

my conclusion: there is a bug in how flash cs4 exports .flash files with tweens to .swf files, AND in how both the FLASH cs4 and FLASHPLAYER cs4 applications handle .swf files with tweens. I haven’t checked these in a web browser just yet. hopefully the flash pug-in is less buggy.

my work-around: I’ going to write my own tween class. Might publish the code on my website soon, for those interested.

We just pushed the new Tween object into an Array.

example:
myArray.push(new Tween(…params…))

the tween is immedeatly executed when pushed into the array.

greetings pensan & a fellow student

Thanks for the solution! I was looking at alternative way to solve the Tween class in AS3.
Much appreciation
Frank

var tweens:Array = new Array();

function create_tween(){
tweens[tween_count] = new Tween( whatever tween settings );
tween_count++;
}

add an Motion_finish event listener so u can remove it when its done, or whatever else u want to do with it.

Since the tween is references by the array, garbage collection wont be deleting it before its done its job.

Just use private var.
