Doodling Program in Flash AS2

Inspired by Dragon's Den this week, when 2 guys demonstrated a fun drawing program they had made, I decided to learn some more about Flash's drawing API to make a very much simpler doodling application in Flash.

Try It



It might look complex, but the hardest bit is only 26 lines of ActionScript, including comments. What makes me laugh the most, is that the whole application comes out as less than 2Kb.

The Code

It's getting late in my time zone, so I won't dissect the code in this post. But enjoy the code, and I'll explain it another time:


//Code from http://dansinteractive.blogspot.com
//default settings
var layernum = 0;
var curcolour:String = "0x000000";
var curlineweight = 5;
//draw the line
drawline = function () {
["layer"+layernum+"_mc"]lineStyle(curlineweight, curcolour, 100);
["layer"+layernum+"_mc"]lineTo(_xmouse, _ymouse);
};
//start drawing on mouse press
_root.paper_mc.onPress = function() {
layernum += 1;
startx = _xmouse;
starty = _ymouse;
createEmptyMovieClip("layer"+layernum+"_mc", this.getNextHighestDepth());
["layer"+layernum+"_mc"]moveTo(startx, starty);
drawlineInterval = setInterval(drawline, 10);
};
//stop drawing on mouse release
_root.paper_mc.onRelease = function() {
clearInterval(drawlineInterval);
}
_root.paper_mc.onReleaseOutside = function() {
clearInterval(drawlineInterval);
}
//colour selector
_root.black_mc.onPress = function () {
curcolour = "0x000000";
}
_root.blue_mc.onPress = function () {
curcolour = "0x0000FF";
}
_root.cyan_mc.onPress = function () {
curcolour = "0x00FFFF";
}
_root.green_mc.onPress = function () {
curcolour = "0x00FF00";
}
_root.magenta_mc.onPress = function () {
curcolour = "0xFF00FF";
}
_root.red_mc.onPress = function () {
curcolour = "0xFF0000";
}
_root.white_mc.onPress = function () {
curcolour = "0xFFFFFF";
}
_root.yellow_mc.onPress = function () {
curcolour = "0xFFFF00";
}
//line thickness selector
_root.line1_mc.onPress = function () {
curlineweight = 1;
}
_root.line3_mc.onPress = function () {
curlineweight = 3;
}
_root.line5_mc.onPress = function () {
curlineweight = 5;
}
_root.line10_mc.onPress = function () {
curlineweight = 10;
}

Happy doodling.
