In the last months I saw a lot of flash drawing games, like Line Rider and Softball.
The concept is very simple yet addictive because the player has the capability to draw the stage.
In the first part of this tutorial I’ll cover the drawing.

The first thing to do, in the first frame, is to create the object where we are going to draw.

Drawing lines in a movieclip

_root.createEmptyMovieClip("terrain", 1);

I have just created an empty movieclip called terrain (and, of course, instanced as terrain) at depth 1.

Now I have to decide the style of my line, I mean the color, the thickness and the transparency (alpha).

_root.terrain.lineStyle(10, 0xff0000, 100);

With this method I am telling flash that I want a line style of 10 pixel width, full red and completely opaque, because the lineStyle method has 3 parameters:

thickness, an integer that indicates the thickness of the line in points valid values are 0 to 255. If 0 (zero), then the style is the hairline, the line that never “grow” when we zoom a movie or movieclip.

rgb, a the hex color value.

alpha, an integer that indicates the alpha value of the line’s color; valid values are 0-100. If a value isn’t indicated, Flash uses 100 (solid). If the value is less than 0, Flash uses 0; if the value is greater than 100, Flash uses 100.

Now that I decided the style of the line, it’s time to draw. We are going to use two methods: moveTo and lineTo.
moveTo(x,y) moves the pen to x and y coordinates without drawing, and lineTo moves the pen to x and y coordinates drawing.

Our very first movieclip, where I draw a red box in the stage, is

createEmptyMovieClip("terrain", 1);

terrain.lineStyle(10, 0xff00ff, 100);

terrain.moveTo(100, 100);

terrain.lineTo(300, 100);

terrain.lineTo(300, 300);

terrain.lineTo(100, 300);

terrain.lineTo(100, 100);

Drawing with the mouse

Now I want to draw with the mouse and not by fixed coordinates.

This is even simpler

createEmptyMovieClip("terrain", 1);

terrain.lineStyle(10, 0xff00ff, 100);

onEnterFrame = function () {

terrain.lineTo(_xmouse, _ymouse);

};

You are able to draw into the movie!

Now I have an issue… I cannot draw “real” curves and it seems to be a delay when I draw.
That’s due to the fps speed of the movie. If you want to make a draw game, you should raise the fps to at least 30 frames per second.

Here it is the same movie playing at 50fps

As you can see, you can create “curves” by adding short lines each close to each oterh.

Draw only when mouse button is pressed

To draw only when you press mouse button, I need a little more actionscript

createEmptyMovieClip("terrain", 1);

terrain.lineStyle(10, 0xff00ff, 100);

imdrawing = false;

onMouseDown = function () {

if (imdrawing == false) {

terrain.moveTo(_xmouse, _ymouse);

imdrawing = true;

}

if (imdrawing == true) {

onEnterFrame = function () {

terrain.lineTo(_xmouse, _ymouse);

};

}

};

onMouseUp = function () {

onEnterFrame = function () {

imdrawing = false;

};

Let’s analyze the script:
Line 1: create the movie clip instanced as “terrain”
Line 2: set the style of the line I am going to draw
Line 3: initialize a flag saying that I am not drawing
Line 4: Actions to perform when the mouse is “down” (when I click the mouse)
Lines 5-8: If i am not drawing, move the “pen” at current mouse location and set the drawing variable at true, to tell the script that now I am drawing
Lines 9-13: If I am drawing, every time I enter the frame a line is traced from the last line drawn to the actual mouse location
Lines 15-19: If the mouse is “up” (I am not clicking the mouse), the imdrawing variable is set back to false value each time I enter the frame. The onEnterFrame here may seem useles but without it, the script won’t work and if you start drawing, you will continue drawing even if the mouse button is not pressed.

Drawing with (more) style

As you noticed, I can decide the style of my lines declaring width, color and alpha.
But what if I want to give my lines some more style?

I have to use some filters Flash has. Flash has several filters you may apply to an object: BevelFilter, BlurFilter, ColorMatrixFilter, ConvolutionFilter, DisplacementMapFilter, DropShadowFilter, GlowFilter, GradientBevelFilter, and GradientGlowFilter.

I’ll examine the ones you may need to use in a draw game

Adding a Bevel

to add a Bevel you have to declare the following parameters:

distance:Number [optional] – The offset distance of the bevel, in pixels (floating point). The default value is 4.

angle:Number [optional] – The angle of the bevel, from 0 to 360 degrees. The default value is 45.

highlightColor:Number [optional] – The highlight color of the bevel, 0xRRGGBB. The default value is 0xFFFFFF.

highlightAlpha:Number [optional] – The alpha transparency value of the highlight color. Valid values are 0 to 1. For example, .25 sets a transparency value of 25%. The default value is 1.

shadowColor:Number [optional] – The shadow color of the bevel, 0xRRGGBB. The default value is 0×000000.

shadowAlpha:Number [optional] – The alpha transparency value of the shadow color. Valid values are 0 to 1. For example, .25 sets a transparency value of 25%. The default value is 1.

blurX:Number [optional] – The amount of horizontal blur in pixels. Valid values are 0 to 255 (floating point). The default value is 4. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

blurY:Number [optional] – The amount of vertical blur in pixels. Valid values are 0 to 255 (floating point). The default value is 4. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

strength:Number [optional] – The strength of the imprint or spread. The larger the value, the more color is imprinted and the stronger the contrast between the bevel and the background. Valid values are 0 to 255. The default value is 1.

quality:Number [optional] – The number of times to apply the filter. The default value is 1, which is equivalent to low quality. A value of 2 is medium quality, and a value of 3 is high quality.

type:String [optional] – The type of bevel. Valid values are “inner”, “outer”, and “full”. The default value is “inner”.

knockout:Boolean [optional] – Applies a knockout effect (true), which effectively makes the object’s fill transparent and reveals the background color of the document. The default value is false (no knockout).

You have to play a bit with the parameters to achieve the effect you prefer.

import flash.filters.BevelFilter;

var distance:Number = 2;

var angleInDegrees:Number = 45;

var highlightColor:Number = 0xff00ff;

var highlightAlpha:Number = 1;

var shadowColor:Number = 0xbb00bb;

var shadowAlpha:Number = 1;

var blurX:Number = 8;

var blurY:Number = 8;

var strength:Number = 10;

var quality:Number = 3;

var type:String = "inner";

var knockout:Boolean = false;

var my_bevel_filter:BevelFilter = new BevelFilter(distance, angleInDegrees, highlightColor, highlightAlpha, shadowColor, shadowAlpha, blurX, blurY, strength, quality, type, knockout);

createEmptyMovieClip("terrain", 1);

terrain.lineStyle(20, 0xdd00dd, 100);

terrain.filters = new Array(my_bevel_filter);

imdrawing = false;

onMouseDown = function () {

if (imdrawing == false) {

terrain.moveTo(_xmouse, _ymouse);

imdrawing = true;

}

if (imdrawing == true) {

onEnterFrame = function () {

terrain.lineTo(_xmouse, _ymouse);

};

}

};

onMouseUp = function () {

onEnterFrame = function () {

imdrawing = false;

};

Line 1: import the filter – it won’t work without this line
Lines 2-13: declaration of the various parameters
Line 14: creation of the filter itself
Line 17: the filter is applied to the movieclip instanced as terrain. Look at the array declaration: that’s because it’s possible to add several effect to a single movieclip

Adding a blur effect

to add a Bevel you have to declare the following parameters:

blurX:Number [optional] – The amount to blur horizontally. Valid values are from 0 to 255 (floating-point value). The default value is 4. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

blurY:Number [optional] – The amount to blur vertically. Valid values are from 0 to 255 (floating-point value). The default value is 4. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

import flash.filters.BlurFilter;

var blurX:Number = 30;

var blurY:Number = 30;

var quality:Number = 3;

var my_blur_filter:BlurFilter = new BlurFilter(blurX, blurY, quality);

createEmptyMovieClip("terrain", 1);

terrain.lineStyle(20, 0xdd00dd, 100);

terrain.filters = new Array(my_blur_filter);

imdrawing = false;

onMouseDown = function () {

if (imdrawing == false) {

terrain.moveTo(_xmouse, _ymouse);

imdrawing = true;

}

if (imdrawing == true) {

onEnterFrame = function () {

terrain.lineTo(_xmouse, _ymouse);

};

}

};

onMouseUp = function () {

onEnterFrame = function () {

imdrawing = false;

};

This script is similar to the previous one, and applies a blur instead of a bevel

Adding a Glow

Parameters:

color:Number [optional] – The color of the glow, in the hexadecimal format 0xRRGGBB. The default value is 0xFF0000.

alpha:Number [optional] – The alpha transparency value for the color. Valid values are 0 to 1. For example, .25 sets a transparency value of 25%. The default value is 1.

blurX:Number [optional] – The amount of horizontal blur. Valid values are 0 to 255 (floating point). The default value is 6. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

blurY:Number [optional] – The amount of vertical blur. Valid values are 0 to 255 (floating point). The default value is 6. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

strength:Number [optional] – The strength of the imprint or spread. The higher the value, the more color is imprinted and the stronger the contrast between the glow and the background. Valid values are 0 to 255. The default is 2.

quality:Number [optional] – The number of times to apply the filter. Valid values are 0 to 15. The default value is 1, which is equivalent to low quality. A value of 2 is medium quality, and a value of 3 is high quality.

inner:Boolean [optional] – Specifies whether the glow is an inner glow. The value true indicates an inner glow. The default is false, an outer glow (a glow around the outer edges of the object).

knockout:Boolean [optional] – Specifies whether the object has a knockout effect. The value true makes the object’s fill transparent and reveals the background color of the document. The default is false (no knockout effect).

import flash.filters.GlowFilter;

var color:Number = 0x33CCFF;

var alpha:Number = .8;

var blurX:Number = 35;

var blurY:Number = 35;

var strength:Number = 2;

var quality:Number = 3;

var inner:Boolean = false;

var knockout:Boolean = false;

var my_glow_filter:GlowFilter = new GlowFilter(color, alpha, blurX, blurY, strength, quality, inner, knockout);

createEmptyMovieClip("terrain", 1);

terrain.lineStyle(20, 0xdd00dd, 100);

terrain.filters = new Array(my_glow_filter);

imdrawing = false;

onMouseDown = function () {

if (imdrawing == false) {

terrain.moveTo(_xmouse, _ymouse);

imdrawing = true;

}

if (imdrawing == true) {

onEnterFrame = function () {

terrain.lineTo(_xmouse, _ymouse);

};

}

};

onMouseUp = function () {

onEnterFrame = function () {

imdrawing = false;

};

Same as before…

Adding a shadow

distance:Number [optional] – The offset distance for the shadow, in pixels. The default value is 4 (floating point).

angle:Number [optional] – The angle of the shadow, 0 to 360Ëš (floating point). The default value is 45.

color:Number [optional] – The color of the shadow, in hexadecimal format 0xRRGGBB. The default value is 0×000000.

alpha:Number [optional] – The alpha transparency value for the shadow color. Valid values are 0 to 1. For example, .25 sets a transparency value of 25%. The default value is 1.

blurX:Number [optional] – The amount of horizontal blur. Valid values are 0 to 255 (floating point). The default value is 4. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

blurY:Number [optional] – The amount of vertical blur. Valid values are 0 to 255 (floating point). The default value is 4. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values.

strength:Number [optional] – The strength of the imprint or spread. The higher the value, the more color is imprinted and the stronger the contrast between the shadow and the background. Valid values are 0 to 255. The default is 1.

inner:Boolean [optional] – Indicates whether or not the shadow is an inner shadow. A value of true specifies an inner shadow. The default is false, an outer shadow (a shadow around the outer edges of the object).

hideObject:Boolean [optional] – Indicates whether or not the object is hidden. A value of true indicates that the object itself is not drawn; only the shadow is visible. The default is false (show the object).

import flash.filters.DropShadowFilter;

var distance:Number = 20;

var angleInDegrees:Number = 45;

var color:Number = 0x000000;

var alpha:Number = .8;

var blurX:Number = 16;

var blurY:Number = 16;

var strength:Number = 1;

var quality:Number = 3;

var inner:Boolean = false;

var knockout:Boolean = false;

var hideObject:Boolean = false;

var my_shadow_filter:DropShadowFilter = new DropShadowFilter(distance, angleInDegrees, color, alpha, blurX, blurY, strength, quality, inner, knockout, hideObject);

createEmptyMovieClip("terrain", 1);

terrain.lineStyle(20, 0xdd00dd, 100);

terrain.filters = new Array(my_shadow_filter);

imdrawing = false;

onMouseDown = function () {

if (imdrawing == false) {

terrain.moveTo(_xmouse, _ymouse);

imdrawing = true;

}

if (imdrawing == true) {

onEnterFrame = function () {

terrain.lineTo(_xmouse, _ymouse);

};

}

};

onMouseUp = function () {

onEnterFrame = function () {

imdrawing = false;

};

Mixing all together

You can obviously mix all styles together, but pay attention: the more complex your line style, the more CPU expansive the movie, as you can see in this example

// bevel filter
import flash.filters.BevelFilter;
var distance:Number = 5;
var angleInDegrees:Number = 45;
var highlightColor:Number = 0xFFFF00;
var highlightAlpha:Number = .8;
var shadowColor:Number = 0x0000FF;
var shadowAlpha:Number = .8;
var blurX:Number = 5;
var blurY:Number = 5;
var strength:Number = 5;
var quality:Number = 3;
var type:String = "inner";
var knockout:Boolean = false;
var my_bevel_filter:BevelFilter = new BevelFilter(distance, angleInDegrees, highlightColor, highlightAlpha, shadowColor, shadowAlpha, blurX, blurY, strength, quality, type, knockout);
// blur filter
import flash.filters.BlurFilter;
var blurX:Number = 30;
var blurY:Number = 30;
var quality:Number = 3;
var my_blur_filter:BlurFilter = new BlurFilter(blurX, blurY, quality);
// shadow

var alpha:Number = .8;
var blurX:Number = 16;
var blurY:Number = 16;
var strength:Number = 1;
var quality:Number = 3;
var inner:Boolean = false;
var knockout:Boolean = false;
var hideObject:Boolean = false;
var my_shadow_filter:DropShadowFilter = new DropShadowFilter(distance, angleInDegrees, color, alpha, blurX, blurY, strength, quality, inner, knockout, hideObject);
// glow
import flash.filters.GlowFilter;
var color:Number = 0x33CCFF;
var alpha:Number = .8;
var blurX:Number = 35;
var blurY:Number = 35;
var strength:Number = 2;
var quality:Number = 3;
var inner:Boolean = false;
var knockout:Boolean = false;
var my_glow_filter:GlowFilter = new GlowFilter(color, alpha, blurX, blurY, strength, quality, inner, knockout);
_root.createEmptyMovieClip("terrain", 1);
_root.terrain.lineStyle(10, 0xff00ff, 100);createEmptyMovieClip("terrain", 1);
terrain.lineStyle(20, 0xdd00dd, 100);
terrain.filters = new Array(my_shadow_filter,my_glow_filter,my_blur_filter,my_bevel_filter);
imdrawing = false;
onMouseDown = function () {
	if (imdrawing == false) {
		terrain.moveTo(_xmouse, _ymouse);
		imdrawing = true;
	}
	if (imdrawing == true) {
		onEnterFrame = function () {
			terrain.lineTo(_xmouse, _ymouse);
		};
	}
};
onMouseUp = function () {
	onEnterFrame = function () {
		imdrawing = false;
	};
};

var inner:Boolean = false;

var knockout:Boolean = false;

var hideObject:Boolean = false;

var my_shadow_filter:DropShadowFilter = new DropShadowFilter(distance, angleInDegrees, color, alpha, blurX, blurY, strength, quality, inner, knockout, hideObject);

// glow

import flash.filters.GlowFilter;

var color:Number = 0x33CCFF;

var alpha:Number = .8;

var blurX:Number = 35;

var blurY:Number = 35;

var strength:Number = 2;

var quality:Number = 3;

var inner:Boolean = false;

var knockout:Boolean = false;

var my_glow_filter:GlowFilter = new GlowFilter(color, alpha, blurX, blurY, strength, quality, inner, knockout);

_root.createEmptyMovieClip("terrain", 1);

_root.terrain.lineStyle(10, 0xff00ff, 100);createEmptyMovieClip("terrain", 1);

terrain.lineStyle(20, 0xdd00dd, 100);

terrain.filters = new Array(my_shadow_filter,my_glow_filter,my_blur_filter,my_bevel_filter);

imdrawing = false;

onMouseDown = function () {

if (imdrawing == false) {

terrain.moveTo(_xmouse, _ymouse);

imdrawing = true;

}

if (imdrawing == true) {

onEnterFrame = function () {

terrain.lineTo(_xmouse, _ymouse);

};

}

};

onMouseUp = function () {

onEnterFrame = function () {

imdrawing = false;

};

That’s all at the moment, donwload all sources and give me feedback.
In the next step I’ll teach you how to save the drawing and add a bouncing ball to the stage…

That is a easy implementation of drawing, but let’s say we want to save our ‘line’ and redraw it.. Would you use a bitmap class ? or save the moveTo, lineTo points ??

This is a good tutorial, but if you are going to impletement the collision detection, it is going to need some hefty modifications. I’ve built one of these engines before. Still, the tutorial is nice :)

Why Don’t You Just Use The
updateAfterEvent() function instead of putting the fps up because if you draw alot of lines flash has to redraw them every time you draw one and if you add filters and increased fps you can make flash slow down and come to a complete stop

Wow, you people complain a lot. You open the window to type this into by pressing F9 in flash. The program you need is Flash, anyone one of them that supports Actionscript 2.0/3.0 (either one will do). This includes Flash MX 2004, Flash 8, and Flash CS3 (Brand New!). It cost’s about $700 USD. This is very much so of a line rider game. Look at the name of ‘Line’ Rider, Hint Hint Nudge Nudge. Don’t expect to learn it all in a hour, or one tutorial! Have patience, you need to know this for a later tutorial (when you make the terrain) and I’ve been studying Flash 8 Pro/Flash MX 2004 Pro for over a year, read over 60 tutorials, read over 500 pages about flash, and still learning from these uber nice people, who take this much time to teach you so much, â€°/10 (Unlimited out of 10). I’ve tried to spread my knowledge through tutorials, video and HTML documents, It takes alot of work, more than these whiners can imagine, Thanks so much â˜»â˜ºâ˜»â˜ºâ˜»

to change the color of the lines all you have to do is make a new button symbol and inside the actionscript panel for the button (actionscript 2) type this code

on (release) {
terrain.lineStyle(13,0×666600,50);
}

thats it and you have to reddo for every color inside the bracket first specify line size
then in the colour pallet specify the color as i have
and the last comma is alpha or transperency

ok thats it

Austin

on June 9, 2008 at 7:43 am

Hey it’s easy to make different color lines with a button changer. Say you want 3 colors, then make 3 different frames. set it so you can see multiple frames. then make the actionscript for the button icons be,

on(release){gotoAndStop(2);}

if you want the next color for the next frame, so ex: if your color is green (1st frame) and your second frame color is red, your color will switch. Actionscript is same for third color exept it’s like:

on(release){gotoAndStop(3);}

and for frame 1 color:

on(release){gotoAndStop(1);}

Enjoy,

PS: you can find use multiple frames tutorial on many google searches.

on (press) {
line.lineStyle (1, 0xFF0000, 100)
}

Only problem how do i limit the amount available to draw because it will carry on drawing until mouse released, THEN it will stop. And only then… Any help apprciated

Awsome!!!!. Emanuele, i want to thank you for the good work, you have taught me more than i already knew… 1 more book to the library in my brain… i am more aware of filters and how to use them. but instead of using more code (var inner:Boolean = false, distance, etc.) i just type the numbers in the filter command:
var glow1:GlowFilter = new GlowFilter(0x00FF00, 100, 15, 15, 4, 3, false, false);
var bevel1:BevelFilter = new BevelFilter(2, 45, 0x65FF00, 1, 0×006600, 1, 5, 5, 3, 3, “inner”, false); // filters

and to save space+lag, i collapse the actions into sertain sections (//filters, //line, //mainActions, etc.);

So thanks

What im trying to do here is create a game where you can click on a color and you write in that color, i.e. click on a black dot and draw black, and maybe also, say, a spray can, where you get the blur affect, and a pencil, just plain drawing. Then you can hit NEXT FRAME and you are presented with the same thing except a blank drawing area and two buttons: previous frame and next frame. And so on for about 200 frames. Also on every frame is a preview button, which, instead of gotoAndStop();
it says gotoAndPlay, so you make your own animation and preview it! But I need help making different colors and such, as I am just starting with AS2. Please email any help to me @ alex.kolozsy@yahoo.com
