Putting it all togetherWith all of this in mind, we're ready to introduce the complete script:
//Global vars
mWidth = 350;
//Create movie clip and mask
counter = -1;
createMovieClip();
animInt = setInterval(doAnim, 17);
function createMovieClip()
{
counter++;
attachMovie('pic' add (counter % 2), 'pic' add counter, counter);
createEmptyMovieClip('mask' add counter, counter + 10000);
this['pic' add counter].setMask(this['mask' add counter]);
}
function doAnim()
{
var currMC = _root['mask' add counter];
if(animIndex <15)
{
var time = animIndex/15;
var dist = 0.5*Math.sin(Math.Pi*(time-0.5)) + 0.5;
with(currMC)
{
clear();
beginFill(0x000000);
lineTo(mWidth,0);
lineTo(mWidth,dist*125);
curveTo(250,dist*40,0,10*dist);
endFill();
}
}
else if (animIndex <35)
{
var time = (animIndex-15)/20;
var dist = 0.5*Math.sin(Math.Pi*(time-0.5)) + 0.5;
with(currMC)
{
clear();
beginFill(0x000000);
lineTo(mWidth,0);
lineTo(mWidth,125);
curveTo(250-100*dist,40+150*dist,0,10+190*dist);
endFill();
}
}
else if (animIndex <= 50)
{
var time = (animIndex-35)/15;
var dist = 0.5*Math.sin(Math.Pi*(time-0.5)) + 0.5;
with(currMC)
{
clear();
beginFill(0x000000);
lineTo(mWidth,0);
lineTo(mWidth,125+75*dist);
curveTo(150,190+10*dist,0,200);
endFill();
}
}
animIndex++;
if(animIndex> 50)
{
animIndex = 0;
_root['pic' add (counter - 1)].removeMovieClip();
_root['mask' add (counter - 1)].removeMovieClip();
createMovieClip();
}
}
