Bug: change property while animating STOP animation

[neves]

Try to change ANY property of a movieClip while it´s animating. The animation will stop!!!

Here´s a simple example:

That's not a bug. That's a misunderstanding you're having with Flash.

A tweened animation - on the timeline - requires that both the start and end frames be able to be animated from one state to another (eg. change of position, rotation or whatnot).

When you programmatically affect a manually tweened animation, you're breaking its tween, and it no longer matches either the start or the end of the tween.

Therefore, for any given object you must either:

a) Only animate manually
or
b) Only animate via scripting

You can of course have a tween animation inside another clip, but you cannot affect the clip's timeline scope where it is being tweened itself.

I find it funny that any time someone doesn't understand anything, they immediately class it as a bug, rather than something they just didn't realise. :P

Yeah, its one of those weird Flash things - just a fact of life of the design of Flash.

To get around it, you would place your animation/tween within another movie clip and change the properties of that new movie clips (letting the animation play within it untouched)

whoops, dthought already said that ;)

Completely right. When something seems wrongly, the first guilty is the tool :)

But hopefully with AS3, we are free from many weirds of flash. But we get new ones :(

this, by the way, is an old one.
