Timeline vs movieclip

1

I been experiment actionscript this few day, some question pop up.

inputing actionscript on a movie clip to make rotation

onClipEvent(enterFrame){
this._rotation=this._rotation+=50;
}

wat happen if you wan the script to be on the timeline and not the movieclip itself…?

this._rotation=this._rotation+=50;

doeen’t work on the timeline.

theclip.onEnterFrame = function(){
this._rotation+=50; 
}

You’ve mixed two operators. += is an operator that adds a value to the existing value, while = is an assignment operator.


anumber = 5;
anumber+=3;
//this is the same as saying
anumber = anumber+3;
