I`m workin on a cd-rom project about art analysis, paintings, artists, bla bla.
It is for a teacher that will use it in his classes.
[color=red]I need to learn how to simulate a blackboard, that he could click and paint on some parts of the paintings.[/color]
Does anyone know a tutorial about that?

here’s how i did a while back:
```auto
this.onEnterFrame = function() {
if (_xmouse>271) {
lineTo(271, _ymouse);
} else if (_xmouse<30) {
lineTo(30, _ymouse);
} else if (_ymouse<45) {
lineTo(_xmouse, 45);
} else if (_ymouse>225) {
lineTo(_xmouse, 225);
} else {
lineTo(_xmouse, _ymouse);
}
};
```
🙂
there might be a better way though… im not really sure

You could also try setMask if you wanted to…
Add this after \_root.createEmptyMovieClip(“line”, 1);
[AS]\_root.createEmptyMovieClip(“mask”, 2);
mask.beginFill(0x000000, 100);
mask.moveTo(20, 0);
mask.lineTo(20, 420);
mask.lineTo(400, 420);
mask.lineTo(400, 0);
line.setMask(mask);[/AS]
I didn’t test it, but yeah…lol.

ahmed: I honestly don’t know which method is better, yours has to go through 4 if statements, but mine still draws content outside of the border, which still uses up resources.
So hmmm.

> it does work, but you will have to draw within a movieclip called ‘line’
```auto
createEmptyMovieClip("line", ++depth)
createEmptyMovieClip("mask", ++depth)
mask.beginFill(0x000000, 100);
mask.moveTo(20, 0);
mask.lineTo(20, 420);
mask.lineTo(400, 420);
mask.lineTo(400, 0);
line.setMask(mask);
line.lineStyle(0)
line.onMouseDown = function() {
this.moveTo(_xmouse, _ymouse)
this.onEnterFrame = function() {
this.lineTo(_xmouse, _ymouse)
}
}
line.onMouseUp = function() {
delete this.onEnterFrame
}
```
or something like that 🙂

A black background is created and it does not work as a mask!

It worked for me…
I did this…
[AS]// 1. SETTING THINGS
\_root.createEmptyMovieClip(“line”,1);
\_root.createEmptyMovieClip(“mask”, 2);
mask.beginFill(0x000000, 100);
mask.moveTo(20, 0);
mask.lineTo(20, 420);
mask.lineTo(400, 420);
mask.lineTo(400, 0);
line.setMask(mask);
// 2. EVENTS IN \_ROOT:
\_root.onMouseDown = function(){
line.moveTo(\_xmouse,\_ymouse);
line.lineStyle(2,0x000000,100);
this.onMouseMove = function(){
line.lineTo(\_xmouse,\_ymouse);
updateAfterEvent();
}
}
\_root.onMouseUp = function(){
this.onMouseMove = null;
}[/AS]
ahmeds method created 2 clips on the same level, you can’t do that, the new one overwrites the old one.
