Рисовалка известная:
this.onMouseDown = function() {
x = this._xmouse;
y = this._ymouse;
this.lineStyle(1, 0xff0000, 100);
this.moveTo(x, y);
this.onEnterFrame = function() {
xx = this._xmouse;
yy = this._ymouse;
this.lineTo(xx, yy);
};
};
this.onMouseUp = function() {
delete this.onEnterFrame;
};
Ну и fps настроить.
