I can't use RemoveMovieClip because I didn't use DuplicateMovieClip to create the drawing.

So they had to add something special in MX:

part B: the clear() method !!!!!!!!

It removes everything I was drawing outside or from within a movieclip. Have a look at my example:

The file setup:

I have put my drawing code in the first frame of the timeline, and that way all my lines get drawn as soon as the movie starts. This is the drawing code:

for (i=10; i <501; i=i + 10)

 {

 _root.createEmptyMovieClip( "triangle"+i , i );

 with ( _root["triangle"+i]);

 {

 lineStyle( 5, 0xff00ff, 100 );

 moveTo( i, 10 );

 lineTo( i,300 ); 

 //lineTo( 100, 300 );

 //lineTo( 200, 200 );

 j=i/10;

 }

 }

I'm just looping the same code we used in the previous example. Now we get to the tricky part. Every instance that we create has a name: triangle10, triangle20, triangle30.....
So you would expect that you could use the setProperty method to change the property of all of one of the instance names, but that doesn't work.

I have to use a trick. I have to clear everything, and then redraw everything with new properties. A user won't even notice that anything has disappeared.

code behind the clear button:

on (release) {

 clear();

 }

code behind the alpha change button:

on (release) {

 clear ();

 for (i=10; i <501; i=i + 10)

 {

 _root.createEmptyMovieClip( "triangle"+i , i );

 with ( _root["triangle"+i]);

 {

 lineStyle( 5, 0xff00ff, 50 );

 moveTo( i, 10 );

 lineTo( i,300 ); 

 //lineTo( 100, 300 );

 //lineTo( 200, 200 );

 j=i/10;

 }

 }

 }
