Creating a Pentomino game using AS3 Part 15
In this tutorial well add the ability to set canvas size in the level editor.
Go to your Flash project and create a new MovieClip based on win_screen. Give the new MC a class path of new_edit_screen. Inside of it we need to include 4 objects at least - two text field inputs tWidth and tHeight (max chars - 2), a button btn_continue and an error message turned into a movie clip with id "incorrect".
Delete it from stage and just keep it in the library. Now return to pentomino_editor.as script file. Inside the constructor, delete all the lines that declare and create the map. Add a listener for btn_reset button and set its click event handler to a function that calls newLevel(). Call newLevel() from the constructor too.
Now create the newLevel() function.
First thing we do here is add an instance of new_edit_screen to the stage.
Add lines that only allow numeric values in tWidth and tHeight, also set their default values:
Set incorrects alpha to 0 (since there was no error yet):
Add a click event listener to btn_continue, set its handler to an internal function editContinue:
Create the editContinue() function inside newLevel(). First thing we do is check if the specified width and height is correct:
If it is correct, we delete the newScreen object from stage, set mapGrid to an empty array and declare width and height variables:
Add two loops that add values to mapGrid based on width and height:
Then calculate grid values and draw the grid:
Full newLevel() function:

public function pentomino_editor()
{
// add shape buttons
for (var i:int = 0; i < 4; i++) {
for (var u:int = 0; u < 3; u++) {
var shapeButton:MovieClip = new edit_shape();
shapeButton.x = 528 + u * 62;
shapeButton.y = 15 + i * 84;
addChild(shapeButton);
shapeButton.bg.alpha = 0.3;
shapeButton.shape.gotoAndStop(3 * i + u + 1);
shapeButtons.push(shapeButton);
shapeButton.addEventListener(MouseEvent.ROLL_OVER, buttonOver);
shapeButton.addEventListener(MouseEvent.ROLL_OUT, buttonOut);
}
}
// buttons
btn_mainmenu.addEventListener(MouseEvent.CLICK, doMainmenu);
btn_reset.addEventListener(MouseEvent.CLICK, function():void{newLevel()});
// new level
newLevel();
}
Now create the newLevel() function.
First thing we do here is add an instance of new_edit_screen to the stage.
var newScreen:MovieClip = new new_edit_screen();
addChild(newScreen);
Add lines that only allow numeric values in tWidth and tHeight, also set their default values:
newScreen.tWidth.restrict = "0-9";
newScreen.tHeight.restrict = "0-9";
newScreen.tWidth.text = 10;
newScreen.tHeight.text = 6;
Set incorrects alpha to 0 (since there was no error yet):
newScreen.incorrect.alpha = 0;
Add a click event listener to btn_continue, set its handler to an internal function editContinue:
newScreen.btn_continue.addEventListener(MouseEvent.CLICK, editContinue);
Create the editContinue() function inside newLevel(). First thing we do is check if the specified width and height is correct:
if (newScreen.tWidth.text == "" || newScreen.tHeight.text == "" || newScreen.tWidth.text == "0" || newScreen.tHeight.text == "0") {
newScreen.incorrect.alpha = 1;
return;
}
If it is correct, we delete the newScreen object from stage, set mapGrid to an empty array and declare width and height variables:
newScreen.parent.removeChild(newScreen);
mapGrid = [];
var width:int = newScreen.tWidth.text;
var height:int = newScreen.tHeight.text;
Add two loops that add values to mapGrid based on width and height:
for (var i:int = 0; i < height; i++) {
mapGrid[i] = [];
for (var u:int = 0; u < width; u++) {
mapGrid[i][u] = 1;
}
}
Then calculate grid values and draw the grid:
// grid settings
calculateGrid();
addChild(gridShape);
gridShape.x = gridStartX;
gridShape.y = gridStartY;
// draw tiles
drawGrid();
Full newLevel() function:
private function newLevel():void {
var newScreen:MovieClip = new new_edit_screen();
addChild(newScreen);
newScreen.tWidth.restrict = "0-9";
newScreen.tHeight.restrict = "0-9";
newScreen.tWidth.text = 10;
newScreen.tHeight.text = 6;
newScreen.incorrect.alpha = 0;
newScreen.btn_continue.addEventListener(MouseEvent.CLICK, editContinue);
function editContinue(evt:MouseEvent):void {
if (newScreen.tWidth.text == "" || newScreen.tHeight.text == "" || newScreen.tWidth.text == "0" || newScreen.tHeight.text == "0") {
newScreen.incorrect.alpha = 1;
return;
}
newScreen.parent.removeChild(newScreen);
mapGrid = [];
var width:int = newScreen.tWidth.text;
var height:int = newScreen.tHeight.text;
for (var i:int = 0; i < height; i++) {
mapGrid[i] = [];
for (var u:int = 0; u < width; u++) {
mapGrid[i][u] = 1;
}
}
// grid settings

Creating a Pentomino game using AS3 Part 29
In this tutorial we will add the ability to edit saved levels.
Firstly go to saved_levels.as constructor and add click event handlers for btn_edit objects of item1, item2 and item3. Set their handlers to anonymous inline functions that call editLevel() method of the root class. Pass the current levels data object from the SharedObject as the only parameter:
Open your project in Flash and go to the thrid frame (where the pentomino_edit instance is located). Give the pentomino_edit instance an id of "edit".
Then go to main.as class and declare a new public variable alreadyExists, set its default value to false.
Create a function called editLevel(). Here we receive levelItem object, set alreadyExists to true, go to the third frame, set levelName and mapGrid variables of the "edit" object to levelItem.name nad levelItem.edit and call that objects calculateAndDraw() and setShapes() methods as shown below:
The alreadyExists variable is used to tell pentomino_edit whether or not it should display the "Create new level" window in the beginning. The levelName variable sets the default name for the level thats being saved. Since we are editing an existing level, we want to use the same name, but still give the user the ability to change the name if they wish. The mapGrid variable is used to draw and manage the grid, we just apply our existing grid array to this variable. The calculateAndDraw() and setShapes() methods are new, I will explain them as I add them to pentomino_editor.as. For now, jsut rememebr to pass levelItem.shapes as parameter for setShapes().
Go to pentomino_editor.as, set mapGrid to public and declare a new public varaible levelName:
In the constructor find the line that calls newLevel(). Here we check if Pentominos alreadyExists value is false before calling the method. If it is true, dont call newLevel() and reset alreadyExists to false.
Now go to newLevel() function. In its internal editContinue() function, right after mapGrid values are set, call a function calculateAndDraw() instead of all the rest code:
Now declare this public function:
You can see the code is all the same, but because we turned it all into a public function it is now reusable.
Finally, add a function setShapes() that receives an array and applies its values to shapeButtons count values:
Now we can load the saved levels in the editor and save them. However, overwriting isnt possible right now, and nor is deleting saved levels, but well work on that in the future tutorials.
Heres full pentomino_editor.as code so far:

Firstly go to saved_levels.as constructor and add click event handlers for btn_edit objects of item1, item2 and item3. Set their handlers to anonymous inline functions that call editLevel() method of the root class. Pass the current levels data object from the SharedObject as the only parameter:
public function saved_levels()
{
savedLevels = SharedObject.getLocal("myLevels");
btn_back.addEventListener(MouseEvent.CLICK, doBack);
if (savedLevels.data.levels != null) levels = savedLevels.data.levels;
tInfo.text = levels.length + " levels (" + savedLevels.size + "B)";
pages = Math.floor(levels.length / 3) + 1;
goPage(1);
btn_previous.addEventListener(MouseEvent.CLICK, function() { goPage(currentPage - 1) } );
btn_next.addEventListener(MouseEvent.CLICK, function() { goPage(currentPage + 1) } );
item1.btn_play.addEventListener(MouseEvent.CLICK, function () { (root as MovieClip).playLevel(levels[3 * (currentPage-1)].grid, levels[3 * (currentPage-1)].shapes); savedLevels.data.levels[3 * (currentPage-1)].played++ } );
item2.btn_play.addEventListener(MouseEvent.CLICK, function () { (root as MovieClip).playLevel(levels[3 * (currentPage-1) + 1].grid, levels[3 * (currentPage-1) + 1].shapes); savedLevels.data.levels[3 * (currentPage-1)+1].played++} );
item3.btn_play.addEventListener(MouseEvent.CLICK, function () { (root as MovieClip).playLevel(levels[3 * (currentPage-1) + 2].grid, levels[3 * (currentPage-1) + 2].shapes); savedLevels.data.levels[3 * (currentPage-1) + 2].played++ } );
item1.btn_edit.addEventListener(MouseEvent.CLICK, function () { (root as MovieClip).editLevel(levels[3 * (currentPage-1)])} );
item2.btn_edit.addEventListener(MouseEvent.CLICK, function () { (root as MovieClip).editLevel(levels[3 * (currentPage-1) + 1])} );
item3.btn_edit.addEventListener(MouseEvent.CLICK, function () { (root as MovieClip).editLevel(levels[3 * (currentPage-1) + 2])} );
}
Open your project in Flash and go to the thrid frame (where the pentomino_edit instance is located). Give the pentomino_edit instance an id of "edit".
Then go to main.as class and declare a new public variable alreadyExists, set its default value to false.
Create a function called editLevel(). Here we receive levelItem object, set alreadyExists to true, go to the third frame, set levelName and mapGrid variables of the "edit" object to levelItem.name nad levelItem.edit and call that objects calculateAndDraw() and setShapes() methods as shown below:
package
{
import flash.display.MovieClip;
import flash.net.SharedObject;
/**
* Open-source pentomino game engine
* @author Kirill Poletaev
*/
public class main extends MovieClip
{
public var alreadyExists:Boolean = false;
public function main()
{
}
public function playLevel(grid:Array, shapes:Array):void {
gotoAndStop(2);
game.playLevel(grid, shapes);
}
public function editLevel(levelItem:Object):void {
alreadyExists = true;
gotoAndStop(3);
edit.levelName = levelItem.name;
edit.mapGrid = levelItem.grid;
edit.calculateAndDraw();
edit.setShapes(levelItem.shapes);
}
public function saveLevelLocal(grid:Array, shapes:Array, levelName:String):void {
var sharedObject:SharedObject = SharedObject.getLocal("myLevels");
if (sharedObject.data.levels == null) sharedObject.data.levels = [];
var levelObject:Object = new Object;
levelObject.grid = grid;
levelObject.shapes = shapes;
levelObject.name = levelName;
levelObject.played = 0;
sharedObject.data.levels.push(levelObject);
sharedObject.flush();
}
}
}
The alreadyExists variable is used to tell pentomino_edit whether or not it should display the "Create new level" window in the beginning. The levelName variable sets the default name for the level thats being saved. Since we are editing an existing level, we want to use the same name, but still give the user the ability to change the name if they wish. The mapGrid variable is used to draw and manage the grid, we just apply our existing grid array to this variable. The calculateAndDraw() and setShapes() methods are new, I will explain them as I add them to pentomino_editor.as. For now, jsut rememebr to pass levelItem.shapes as parameter for setShapes().
Go to pentomino_editor.as, set mapGrid to public and declare a new public varaible levelName:
public var mapGrid:Array = [];
public var levelName:String = "My Level"
In the constructor find the line that calls newLevel(). Here we check if Pentominos alreadyExists value is false before calling the method. If it is true, dont call newLevel() and reset alreadyExists to false.
// new level
if (!Pentomino.alreadyExists) {
newLevel();
}
if (Pentomino.alreadyExists) {
Pentomino.alreadyExists = false;
}
Now go to newLevel() function. In its internal editContinue() function, right after mapGrid values are set, call a function calculateAndDraw() instead of all the rest code:
private function newLevel():void {
canDraw = false;
var newScreen:MovieClip = new new_edit_screen();
addChild(newScreen);
newScreen.tWidth.restrict = "0-9";
newScreen.tHeight.restrict = "0-9";
newScreen.tWidth.text = 10;
newScreen.tHeight.text = 6;
newScreen.incorrect.alpha = 0;
newScreen.btn_continue.addEventListener(MouseEvent.CLICK, editContinue);
function editContinue(evt:MouseEvent):void {
if (newScreen.tWidth.text == "" || newScreen.tHeight.text == "" || newScreen.tWidth.text == "0" || newScreen.tHeight.text == "0") {
newScreen.incorrect.alpha = 1;
return;
}
newScreen.parent.removeChild(newScreen);
mapGrid = [];
var height:int = newScreen.tHeight.text;
var width:int = newScreen.tWidth.text;
for (var i:int = 0; i < height; i++) {
mapGrid[i] = [];
for (var u:int = 0; u < width; u++) {
mapGrid[i][u] = 1;
}
}
calculateAndDraw();
}
}
Now declare this public function:
public function calculateAndDraw():void {
// grid settings
calculateGrid();
gridShape.x = gridStartX;
gridShape.y = gridStartY;
// draw tiles
drawGrid();
// canPutShape settings
canPutShape.graphics.clear();
canPutShape.graphics.lineStyle(2, 0xff0000);
canPutShape.graphics.drawRect(0, 0, gridCellWidth, gridCellWidth);
canPutShape.alpha = 0;
canDraw = true;
}
You can see the code is all the same, but because we turned it all into a public function it is now reusable.
Finally, add a function setShapes() that receives an array and applies its values to shapeButtons count values:
public function setShapes(sh:Array):void {
for (var i:int = 0; i < shapeButtons.length; i++) {
shapeButtons[i].count.value = sh[i];
}
}
Now we can load the saved levels in the editor and save them. However, overwriting isnt possible right now, and nor is deleting saved levels, but well work on that in the future tutorials.
