# Motion Tween Problem

Hi all, new here. Just looking for help with my code below. The 'Night' rectangle is a black rectangle, then with a blue ('Day') rectangle overlayed ontop of it. I want the 'Day' rectangle to ease out to just leave the black rectangle there. I have been messing around with this code for ages and cannot figure out what is wrong. Any ideas??

Thanks

import mx.transitions.Tween;
import mx.transitions.easing.*;
this.createEmptyMovieClip("night", 8);
Night();
this.createEmptyMovieClip("dayTween", 9);
Day(dayTween, 100);
new Tween(dayTween, "_alpha", Soft.easeOut, 0, 100, 1, true);
function Night() {
mainMovie.lineStyle(1, 0x000000, 100);
mainMovie.beginFill(0x000000, 100);
mainMovie.moveTo(0, 0);
//draw the building 
mainMovie.lineTo(550, 0);
mainMovie.lineTo(550, 200);
mainMovie.lineTo(0, 200);
mainMovie.lineTo(0, 0);
}
function Day(target_mc:MovieClip, fillAlpha:Number):Void {
with (target_mc) {
mainMovie.lineStyle(1, 0x3399FF, 100);
mainMovie.beginFill(0x3399FF, fillAlpha);
mainMovie.moveTo(0, 0);
//draw the building 
mainMovie.lineTo(550, 0);
mainMovie.lineTo(550, 200);
mainMovie.lineTo(0, 200);
mainMovie.lineTo(0, 0);
endFill();
}
}

Two things: you need to define mainMovie as a var, and also not reference it

var mainMovie = this;

right before you create your first clip.

Then remove mainMovie references from Day(), so it is:

function Day(target_mc:MovieClip, fillAlpha:Number):Void {
with (target_mc) {
lineStyle(1, 0x3399FF, 100);
beginFill(0x3399FF, fillAlpha);
moveTo(0, 0);
//draw the building
lineTo(550, 0);
lineTo(550, 200);
lineTo(0, 200);
lineTo(0, 0);
endFill();
}
}

It'll work now. As a matter of convention, function names do not begin with
capital letters - class names do.
