play and stop movieclip with button

[Froschloeffel]

i want to play an mc from frame 1 to frame 20 - so far so good - here ist the script

rot_anim.stop();
function rot_animation (evt:MouseEvent) {
    rot_anim.gotoAndPlay(1);
    rot_anim.addEventListener(Event.ENTER_FRAME,fStop);
}
function fStop(evt:Event)
{
    if (rot_anim.currentFrame>19) { 
       rot_anim.stop();
       rot_anim.removeEventListener(Event.ENTER_FRAME,fStop);
    }
}
rot_anim.addEventListener(MouseEvent.CLICK, rot_animation);

now i would like to start to play the mc with a click on a button - but that does not work and i do not know what i am doing wrong. can anybody help me?

here is the script for the button calling the function

button1.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void
{
	rot_animation.play();
}

Why are you trying to tell a function to play?

[Froschloeffel]

i thougt i have to, because in it there are the comands that rot_anim has, after the comand play, to stop at frame 19 - is that wrong?

if i say rot_anim.play(); it starts playing after i click on the button, but it does not stop animore... it plays over and over and over...

how else do i have to write it then?

You understand that functions aren't movieclips, yes? Functions don't have timelines. You don't "play" a function, you just call it.

[Froschloeffel]

i thought, that i call it with the name and inside is the movieclip...

obviousley this is wrong

the movieclips name is rot_anim

that it stops at the end of the timeline is the function rot_animation

can you please tell me, how i have to write it?

You just call the function, like all functions are called in ActionScript.

Not sure why you're using AS3 though. I assume this isn't a project intended for web use.

[Froschloeffel]

no it is not for web

i have a problem calling the function because i do not know the synthax for it.

several times i asked in this forum, where i could learn as3. i never got an answer on this question. it seems to be some secret knowledge?

maybe you help me to write it properly? that would be nice ;o)
