Subtract a dynamic shape from another

[gameon]

Hi, I have a dynamic shape made from filling the space inbetween some lines. I really need it to be possible to be able to then substract that shpa efrom a square that I have on the stage. (which can be there already or drawn dynamically too...

Can this be done?

M@?

If your shape is a movieclip you should be able to use it as a mask over the square, hard to say exactly how to approach this without seeing the image though.

Hi Wangbar - I just got an email from flash kit:

this.beginFill(0xff0000, 100);

// draw a square (clockwise)
this.moveTo(0, 0);
this.lineTo(200, 0);
this.lineTo(200, 200);
this.lineTo(0, 200);
this.lineTo(0, 0);

// cut out a triangle in the square (draw a triangle counter-clockwise)
this.moveTo(100, 50);
this.lineTo(50, 150);
this.lineTo(150, 150);
this.lineTo(100, 50);

this.endFill();

Cheers for you help - cheers lots, m@)
