Creating a Pentomino game using AS3 Part 1

Today well start making a game based on pentomino.

Basically, I have a school project to do on Pentomino, and Im going to create a game based on the principle. I also want to share the code with other programmers, so Im writing a step-by-step tutorial series and then releasing the game as an open-source project.

The game is made using Flash and FlashDevelop, although you dont need to follow my example strictly and as long as you understand the code, you can use any IDE you like.

I am going to use Flash for animations and graphics mostly, and have all my code written in FlashDevelop (because I like it a lot better than the built in actions editor in Flash).

If you want to do this the same way as me, create a new AS3 project and add a new empty MovieClip to stage. Make sure its coordinates are 0,0. Set its class path to "pentomino_game".

Now open FlashDevelop, Project > New Project. Choose Flash IDE project and select the folder your Flash file is in. When the project is created, add a new .as class to the directory and edit it using FlashDevelop. Import two classes for now - MovieClip and Sprite. Make the pentomino_game class extend MovieClip.

Declare five private variables - mapGrid, gridShape, gridStartX, gridStartY and gridCellWidth and set their values as shown below:

package  
{
import flash.display.MovieClip;
import flash.display.Sprite;

/**
 * Open-source pentomino game engine
 * @author Kirill Poletaev
 */

public class pentomino_game extends MovieClip
{
private var mapGrid:Array = [];

private var gridShape:Sprite = new Sprite();
private var gridStartX:int = 30;
private var gridStartY:int = 30;
private var gridCellWidth:int = 30;

public function pentomino_game() {}

}

}

Now, in the constructor, were going to add a temporary value for mapGrid. Why temporary? Because in the future, all the maps will be stored somewhere and not hardcoded in the constructor function. Right now, make it a 10x6 grid with values "1" and "0".

Basically, "1" means a tile and "0" means a hole. Using this method youll be able to create more complex grids than just boring rectangles.

// default map
mapGrid = [
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 0, 0, 1, 1, 1, 1],
[1, 1, 1, 1, 0, 0, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
];

Note that the map I created is not a valid one. It will not work for a pentomino puzzle. The reason for that is the number of tiles cant be divided by 5 and remain a round number. But just for the sake of this tutorial and debugging, were going to leave these 4 holes there.

Now we add the gridShape Sprite to stage and set its coordinates:

// grid settings
addChild(gridShape);
gridShape.x = gridStartX;
gridShape.y = gridStartY;

Then we call a function drawGrid() that draws the map.

public function pentomino_game() 
{
// default map
mapGrid = [
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 0, 0, 1, 1, 1, 1],
[1, 1, 1, 1, 0, 0, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
];

// grid settings
addChild(gridShape);
gridShape.x = gridStartX;
gridShape.y = gridStartY;

// draw tiles
drawGrid();
}

The map is drawn by first clearing gridShapes graphics, then looping through all mapGrid items and drawing a cell where it is needed:

private function drawGrid():void {
gridShape.graphics.clear();
var width:int = mapGrid[0].length;
var height:int = mapGrid.length;

var i:int;
var u:int;

// draw background
for (i = 0; i < height; i++) {
for (u = 0; u < width; u++) {
if (mapGrid[i][u] == 1) drawCell(u, i, 0xffffff, 1, 0x999999);
}
}
}

private function drawCell(width:int, height:int, fill:uint, thick:Number, line:uint):void {
gridShape.graphics.beginFill(fill);
gridShape.graphics.lineStyle(thick, line);
gridShape.graphics.drawRect(width * gridCellWidth, height * gridCellWidth, gridCellWidth, gridCellWidth);
}

You can see that we use the drawing API to draw the tiles.

Now we have a working tile map system. You can create maps and change their appearance. The results may vary, but it should look something like this:

Full code so far:

package  
{
import flash.display.MovieClip;
import flash.display.Sprite;

/**
 * Open-source pentomino game engine
 * @author Kirill Poletaev
 */

public class pentomino_game extends MovieClip
{
private var mapGrid:Array = [];

private var gridShape:Sprite = new Sprite();
private var gridStartX:int = 30;
private var gridStartY:int = 30;
private var gridCellWidth:int = 30;

public function pentomino_game() 
{
// default map
mapGrid = [
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 0, 0, 1, 1, 1, 1],
[1, 1, 1, 1, 0, 0, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
];

// grid settings
addChild(gridShape);
gridShape.x = gridStartX;
gridShape.y = gridStartY;

// draw tiles
drawGrid();
}

private function drawGrid():void {
gridShape.graphics.clear();
var width:int = mapGrid[0].length;
var height:int = mapGrid.length;

var i:int;
var u:int;

// draw background
for (i = 0; i < height; i++) {
for (u = 0; u < width; u++) {
if (mapGrid[i][u] == 1) drawCell(u, i, 0xffffff, 1, 0x999999);
}
}
}

private function drawCell(width:int, height:int, fill:uint, thick:Number, line:uint):void {
gridShape.graphics.beginFill(fill);
gridShape.graphics.lineStyle(thick, line);
gridShape.graphics.drawRect(width * gridCellWidth, height * gridCellWidth, gridCellWidth, gridCellWidth);
}

}

}

Up all night the LinkedIn Intern Hackday Day 1

Update: the official photos, videos, and submitted projects are now available on the Intern Hackday site.

Friday, July 29, we kicked off the LinkedIn Intern Hackday. It was the first ever public hackday weve had at LinkedIn: interns from all over Silicon Valley were invited to come down to LinkedIn headquarters, form teams, hack for 24 hours, and build something awesome. Roughly 165 interns came and just about all of them stayed up all night. To keep them going, we had a ton of food delivered - sandwiches at 7, pizza at 9, Chinese food at 2am, breakfast burritos at 7am, more pizza at noon, hot truck at 4 - and vast quantities of caffeine at all hours.

This is a quick blog post with some of the sights and sounds from day 1. These are mostly from my iPhone (apparently, the only camera I have on me during most LinkedIn events), the LinkedIn University Facebook Page and one of our volunteers, Hemendra. Keep your eye on the Intern Hackday site for the full official set of photos, videos and, most importantly, the submitted hacks from the event.

The interns check-in at 6pm on Friday

One intern came prepared, ready with his own case of energy drinks

But dont worry, we were well stocked with food and drinks of our own

And, of course, plenty of caffeine

Getting settled in

Cal Poly represent

165+ laptops, phones, monitors, and keyboard meant a lot of wires

Every type of laptop, netbook, headphone, phone, tablet and gizmo could be found

Adam Nash kicks off the hacking at 7pm

The planning begins

Secret tactics

A few interns figured out the winning strategy early on

The hacking begins.

And finally, a video of 165 hackers hard at work.
