Creating controls with rollover states
February 23rd, 2008 . by polyGeekHere is a short - 6 minute - video tutorial to help you create rollovers effects for your video interface controls.

If you want to use the new API call - playBackward() - mentioned in this video you’ll need the latest videoMaru 3.5 beta SWC - see link at top of window.
playBackward( mc ) works be taking the MovieClip that you pass and creating an onEnterFrame function. On each enterFrame event it says: gotoAndStop( this._currentframe - 1 );
Then it checks to see if this._currentframe == 1. If so then it deletes the onEnterFrame function.
It looks like this:
function playBackward( mc:MovieClip ):Void { mc.onEnterFrame = function():Void {
this.gotoAndStop( this._currentframe - 1 );
if( this._currentframe == 1 ) {
delete this.onEnterFrame;
}
}
}
Just wanted to say thanks for videomaru.
As for the rollover states… It only seems logical to add to your playBackward function with a playForward function. Now the rollover and rollout are flawless.
this.mc.onRollOver = function():Void{
this.playingThis = 1;
this._parent.playForward(mc);
}
this.mc.onRollOut = function():Void{
this.playingThis = 0;
this._parent.playBackward(mc);
}
function playBackward( mc:MovieClip ):Void {
mc.onEnterFrame = function():Void {
this.gotoAndStop( this._currentframe - 1 );
if( this._currentframe == 1 || this.playingThis == 1 )
{
trace(playingThis);
delete this.onEnterFrame;
}
}
}
function playForward( mc:MovieClip ):Void {
mc.onEnterFrame = function():Void {
this.gotoAndStop( this._currentframe + 1 );
if( this._currentframe == this._totalframes || this.playingThis == 0 )
{
//trace(playingThis);
delete this.onEnterFrame;
}
}
}
