Button - play on rollover

[Yippie]

hay

i have a button (cool huh?)
in the over frame i have a mc, which has ofcourse an animation.

now, when i test the button and rollover, the anim plays. np. but when i rollout the anim stops and the state is up
but i dont want that, cause that is ugly
so how can i make a button which plays the whole anim in the over state, no matter how long or short you rollover, just play it full and the stops

there is probably a very logic solution but i didnt found it...

One way is to have a movie clip with an invisible button in it.

An invisible button just has a hit state - so it responds to the mouse but you can't see it when the movie runs.

Create a movie clip with your animation in it.

Make the first frame of your movie equivalent to your up state, but have a stop() action in it to stop the animation from running.

In the last frame of your animation, put

gotoAndStop(1);

.
In a separate layer (this keeps things neat), place your invisible button and size/position it so it covers the whole animation.

Put this code on the button:

on(rollover){
gotoAndPlay(2);
}

Now drag an instance of your movie on to the stage and test it.
