What"s a Match-3 Game?

Before we begin via the tutorial on exactly how to develop a match-3 game through carolannpeacock.com, we should focus on the basic idea behind such games. I think the majority of of you currently recognize games choose Candy Crush Saga or also acquired invited to play such games. The main concept is simple:

The game is composed of a grid via multiple elements in different shapes or colors (these facets are also referred to as blocks in this tutorial). Whenever before a team of at least 3 elements of the exact same form is linked, they can be rerelocated from the grid. That"s why these games are additionally dubbed match-3 games. After a team is rerelocated, the existing blocks in the grid fall down and also fill the empty spots. Empty spots at the top of the grid are then filled via new, randomly developed blocks. The user have the right to now go on via rerelocating groups of matching facets.

The game continues like that till a particular criteria is reached, for example:

A particular score is completed. No more teams deserve to be rerelocated. Some unique elements have actually been rerelocated. And so on ... you obtain the idea!

We will stop our game as soon as there are no teams left to rerelocate. When this happens, we show the player score and administer a button to start a new game. The player deserve to remove a team by clicking it and gets points based on the variety of facets in the group.

You are watching: Make a macth

When you create the game via this tutorial you will learn how to:

Create random objects and also place them within a grid layout. Find teams of facets of the exact same type within the grid. Rerelocate objects from the grid. Move objects down to fill empty spots. Communicate events making use of signals. Load and usage custom fonts.

If you are not yet familiar with the standard setup of jobs, QML or exactly how to produce your very own entities, please think about taking a look at the following tutorial to aid you gain started:

Now we are prepared to go! But initially things first, we still need to collection the layout for our match-3 game: In the game Juicy Squash we desire to mix the the majority of delicious smoothie in the world! So let"s fill the blender in our kitchen with all kinds of fruits and squash them to reach the perfect juicy score! ;-)


We also carry out the complete resource code of Juicy Squash made with carolannpeacock.com in the carolannpeacock.com SDK. See here wbelow to find the demo in your SDK directory.

You can discover two game versions there:


All the sources of the game must be placed within the assets catalog of the task. You deserve to downpack them below.

Setting Up the Project

Let us begin with creating a brand-new empty project in QtCreator. We will certainly use the portrait mode as interconfront orientation. After you end up the job setup, please include the downloaded sources to the assets folder of your project. They need to show up in the Other filesassets brochure of the job tree. Please take care not to add an additional subcatalog that might be developed once you unload the resources archive.

That"s all the setup we require, let"s begin to implement the game!

Basic Game Layout

The initially point we desire to attain is to develop the fruits and also place them within a grid. But prior to we add any kind of new entities and also complex calculations, you should replace your Key.qml via the following implementation.


import carolannpeacock.com 3.0 import QtQuick 2.0 GameWindow id: gameWindow activeScene: scene // the dimension of the Window can be adjusted at runtime by pressing Ctrl (or Cmd on Mac) + the number keys 1-8 // the content of the logical scene size (480x320 for landscape mode by default) gets scacaused the home window size based upon the scaleMode // you have the right to set this size to any kind of resolution you would favor your job to begin through, many of the times the among your primary target gadget // this resolution is for iPhone 4 & iPhone 4S screenWidth: 640 screenHeight: 960 // tradition font loading of ttf fonts FontLoader id: gameFont source: "../assets/fonts/akaDylan Plain.ttf" Scene id: scene // the "logical size" - the scene content is auto-scacaused enhance the GameWindow dimension width: 320 height: 480 // building to host game score residential or commercial property int score // background image BackgroundImage source: "../assets/JuicyBackground.png" anchors.centerIn: scene.gameWindowAnchorItem // display screen score Text // collection font font.family: gameFont.name font.pixelSize: 12 color: "red" text: scene.score // collection place anchors.horizontalCenter: parent.horizontalCenter y: 446 These few lines will certainly administer an easy style for our game. We specify a BackgroundImage that already reflects the game layout. This picture is bigger than the actual scene dimension we identified. On different tools via other display screen ratios even more of the background picture will present in order to prevent dark borders. Please examine out the tutorial on scaling modes and support of multiple display sizes if you are interested in this topic.

We also display the player score in our very own tradition font. This is completed by including the FontLoader component and also establishing the source to our font in the assets brochure.

Let"s hit play and also view if everything functions fine up to this point! Your screen should look prefer that:


Show Me Some Fruits!

Now let"s relocate on to the fruits we desire to include. We have actually many various kinds of fruits in the game, however beneath the various appearance they share the exact same game logic. We have the right to treat them as a single game entity through different visual depictions. Just develop a brand-new file Block.qml within your qml folder and add the following lines of code.


import carolannpeacock.com 3.0 import QtQuick 2.0 EntityBase id: block entityType: "block" // each block knows its type and its position on the field building int form home int row home int column // emit a signal as soon as block is clicked signal clicked(int row, int column, int type) // show different imeras for block types Image anchors.fill: parent source: if (form == 0) rerevolve "../assets/Apple.png" else if(type == 1) return "../assets/Banana.png" else if (form == 2) rerevolve "../assets/Ovariety.png" else if (kind == 3) return "../assets/Pear.png" else return "../assets/BlueBerry.png" // take care of click event on blocks (cause clicked signal) MouseArea anchors.fill: parent onClicked: parent.clicked(row, column, type) The primary concept is to set up each block as an independent entity that knows its position on the grid and its form. Based on the value of the kind building we ssuggest show a different fruit picture. In order to listen to clicks on a fruit by the player, we included a MouseArea that covers the totality item. Whenever a block is clicked, it emits a signal that holds all the pertinent information. This method we can conveniently usage a single feature to handle the clicked signals from all the blocks in the game. And furthereven more, we straight know at which grid position the click developed and also what type of fruit is at that position.

The fruits are now prepared to be produced and added to the game, however we will require most game logic and calculations for the grid. We execute not want to directly area all of that within our game scene. To attain a far better separation of code and also clear duties of components we will certainly create a second item GameArea.qml to host the grid of fruits and all the essential calculations.


import carolannpeacock.com 3.0 import QtRapid 2.0 Item id: gameArea // shall be a multiple of the blockSize // the game field is 8 columns by 12 rows huge width: blockSize * 8 height: blockSize * 12 // properties for game location configuration building double blockSize property int rows: Math.floor(elevation / blockSize) residential property int columns: Math.floor(width / blockSize) // range for handling game area home var field: <> // game over signal signal gameOver() // calculate area index feature index(row, column) return row * columns + column // fill game field via blocks attribute initializeField() // clear field clearField() // fill area for(var i = 0; i rows; i++) for(var j = 0; j columns; j++) gameArea.field = createBlock(i, j) // clear game area attribute clearField() // rerelocate entities for(var i = 0; i gameArea.field.length; i++) var block = gameArea.field if(block !== null) entityManager.removeEntityById(block.entityId) gameArea.area = <> // produce a new block at particular place function createBlock(row, column) // connumber block var entityProperties = width: blockSize, height: blockSize, x: column * blockSize, y: row * blockSize, type: Math.floor(Math.random() * 5), // random kind row: row, column: column // add block to game location var id = entityManager.createEntityFromUrlWithProperties( Qt.resolvedUrl("Block.qml"), entityProperties) // link click signal from block to handler attribute var entity = entityManager.getEntityById(id) entity.clicked.connect(handleClick) return entity // handle user clicks feature handleClick(row, column, type) // ... At the height of the file we define the dimension of the game location and also some added properties for the block dimension (dimension of fruits) and the complete variety of rows and also columns of the grid. We likewise already prepare a signal we will certainly use later on to relay the message that the game is over. The the majority of vital part of the object is the field building. It represents the game field (grid) as an variety of block-entities. We then have actually a couple of attributes that assist us to fill our game area with fruits:

index(row, column) Returns the array index for a particular grid position. We deserve to usage this function to conveniently accessibility a block in the field range for a provided grid place (row and column). initializeField() Empties the grid and fills it through new blocks. clearField() Correctly removes all block-entities from the game location and clears the area variety. createBlock(row, column) Adds a new, random block to the game at a particular grid position. handleClick(row, column, type) Will manage all the clicked-signals from the blocks we create. The parameters tell us the position and also the kind of the block that has been clicked. We affix the signal of our dynamically developed blocks via this attribute with the entity.clicked.connect(handleClick) command also.

Let"s include the game location to our scene and also cause the initialization of the game field.


GameWindow id: gameWindow // ... // initialize game as soon as home window is fully loaded onSplashScreenFinished: scene.startGame() // for dynamic creation of entities EntityManager id: entityManager entityContainer: gameArea // practice font loading of ttf fonts FontLoader id: gameFont source: "../assets/fonts/akaDylan Plain.ttf" Scene id: scene // ... // game area holds game area with blocks GameArea id: gameArea anchors.horizontalCenter: scene.horizontalCenter blockSize: 30 y: 20 // initialize game attribute startGame() gameArea.initializeField() scene.score = 0 We additionally include the EntityManager component we are utilizing in the createBlock-attribute and specify the game area as the entityContainer for all the blocks. The startGame-function resets the points and also the game field. It will certainly be dubbed each time a brand-new game has to be started. The line onSplashScreenFinished: scene.startGame() will create the exceptionally initially initialization after the carolannpeacock.com splash display is gone. When you begin the game at this suggest you have to currently see the grid filled via fruits! Looks delicious!

How to Match-3

This tutorial is a guide on just how to develop a match-3 game, so we want to uncover out once 3 or even more fruits are together. When creating the fruits, we already attach their clicked signal to our handler feature by stating entity.clicked.connect(handleClick). We are then going to examine all the blocks that are next-door neighbors to the one we clicked. If more than 3 blocks of the same kind are connected, they will certainly be removed.


Item id: gameArea // ... function handleClick(row, column, type) // copy current field, enables us to readjust the range without modifying the real game field // this simplifies the algorithms to search for associated blocks and their removal var fieldCopy = field.slice() // count and delete linked blocks var blockCount = getNumberOfConnectedBlocks(fieldCopy, row, column, type) if(blockCount >= 3) removeConnectedBlocks(fieldCopy) // recursively examine a block and also its neighbors // retransforms variety of associated blocks feature getNumberOfConnectedBlocks(fieldCopy, row, column, type) // rerelocate previously noted blocks feature removeConnectedBlocks(fieldCopy) // search for blocks to remove for(var i = 0; i fieldCopy.length; i++) if(fieldCopy === null) // remove block from field var block = gameArea.field if(block !== null) gameArea.field = null entityManager.removeEntityById(block.entityId) The first step is to implement the handleClick-attribute. We gain the place and the form of the block that was clicked as parameters of the function. We then go on through copying the totality present game area into a new neighborhood variable fieldCopy. For this objective the JavaScript function slice() is provided, which is among the fastest means to copy a entirety range. We will certainly need this copy later when we search for and also remove linked blocks.

The many essential function below is getNumberOfConnectedBlocks. It calculates the number of linked blocks based on four parameters:

fieldCopy Hregarding be a copy of the existing game area. The function will adjust the provided area to note blocks that have actually currently been counted. Whenever a block of the wanted type is found in the area, it will certainly be removed from the area to prevent checking it aobtain. row and column Specify the founding point for the search. type Sets the preferred block form for the search.

Each call to getNumberOfConnectedBlocks will return zero if:

The row or the column parameter is exterior of the bounds of our game field. Tright here is no block at the given place. This happens once a block has actually been counted and removed from the copy of the area. The block at the given place doesn"t enhance the desired type.

If neither is the instance, a valid block has been discovered. The function then gets rid of this block from the field copy. After that all the bordering blocks are checked in the same method by calling getNumberOfConnectedBlocks aacquire, and also the number of all connected blocks in the neighborhood is summed up and also changed.

To really understand the idea behind this algorithm, you have to have the ability to totally understand also what it suggests when a function calls itself within its attribute body. This idea is dubbed "recursion". Maybe you need to read up a little even more on this topic, however i am positive that you have the right to understand it. ;-)

Once we have the result of this awesome attribute, we have the right to easily react to the number of the connected blocks we discovered. If there are more than 3, we remove them from the actual game field based upon the empty spots in the copy of the field.

Note: JavaScript arrays are instantly passed by reference, so the transforms made to the area copy by the attributes will not be shed. This is necessary, because we work-related with these changes in other features choose the additional recursion calls and the removeConnectedBlocks attribute.

Press play and also you have the right to already start removing blocks!


Filling the Holes

Now we want to relocate dvery own higher blocks and create new fruits eextremely time we rerelocate a group. We use a new attribute moveBlocksToBottom for that function. This attribute will be dubbed in our clicked-handler after we rerelocated a group of blocks. In enhancement, we additionally calculate and also boost the player score to finish our handler attribute.


Item id: gameArea // ... feature handleClick(row, column, type) // copy current area, allows us to change the array without editing and enhancing the actual game field // this simplifies the algorithms to search for connected blocks and their removal var fieldCopy = area.slice() // count and delete linked blocks var blockCount = getNumberOfConnectedBlocks(fieldCopy, row, column, type) if(blockCount >= 3) removeConnectedBlocks(fieldCopy) moveBlocksToBottom() // calculate and rise score // this will rise the included score for each block, e.g. 4 blocks will certainly be 1+2+3+4 = 10 points var score = blockCount * (blockCount + 1) / 2 scene.score += score // ... // relocate remaining blocks to the bottom and also fill up columns via brand-new blocks attribute moveBlocksToBottom() // examine all columns for empty fields for(var col = 0; col columns; col++) // start at the bottom of the field for(var row = rows - 1; row >= 0; row--) // discover empty spot in grid if(gameArea.field === null) // find block to move dvery own var moveBlock = null for(var moveRow = row - 1; moveRow >= 0; moveRow--) moveBlock = gameArea.field if(moveBlock !== null) gameArea.field = null gameArea.field = moveBlock moveBlock.row = row moveBlock.y = row * gameArea.blockSize break // if no block discovered, fill whole column up via brand-new blocks if(moveBlock === null) for(var newRow = row; newRow >= 0; newRow--) var newBlock = createBlock(newRow, col) gameArea.field = newBlock newBlock.row = newRow newBlock.y = newRow * gameArea.blockSize // column already filled up, no must check higher rows aacquire break // finish examine rows starting from the bottom // end check columns for empty areas The implementation of the moveBlocksToBottom-attribute takes care of the complying with tasks:

We will fill up eexceptionally column of the game area from the bottom to the height, founding with the column on the left. Whenever before we encounter an empty spot in a column, we search for the next block above and also move it down. If no even more blocks can be uncovered, the totality column is filled up with brand-new fruits. We then directly relocate on to checking the next column.

We use this feature after we rerelocated a team of linked blocks. The player score is then increased in a way that considers the variety of blocks that have actually been removed. A group of 3 blocks will certainly amount to 1+2+3 = 6 points, a team of 4 will certainly offer 1+2+3+4 = 10 points and so on. With these changes you deserve to currently begin to play and also get points!

Game Over?

A game is no fun if it is never over. Well, in truth the game is already over when tright here are no more blocks accessible to remove. At the moment, the user then is stuck to nopoint to do. We want to recognize if no even more teams of three are existing and trigger our gameover-signal when that happens. We can easily do that by trying the getNumberOfConnectedBlocks feature on all the blocks of the area. We will cover that by adding a brand-new attribute isGameOver to our game location.


Item id: gameArea // ... attribute handleClick(row, column, type) // ... if(blockCount >= 3) // ... // emit signal if game is over if(isGameOver()) gameOver() // ... // inspect if game is over attribute isGameOver() var gameOver = true // copy area to search for connected blocks without editing the actual area var fieldCopy = area.slice() // search for linked blocks in area for(var row = 0; row rows; row++) for(var col = 0; col columns; col++) // test all blocks var block = fieldCopy if(block !== null) var blockCount = getNumberOfConnectedBlocks(fieldCopy, row, col, block.type) if(blockCount >= 3) gameOver = false break rerevolve gameOver As we carry out not desire to readjust the current game field when we inspect for linked blocks, we again run on a copy of the area array. The feature then functions as follows:

We go over all the blocks in the field and also search for groups that are bigger than 3 blocks. When we find such a team, we deserve to automatically sheight the search. If we do not find any type of teams, the function retransforms "true" and we deserve to emit the signal thereafter. Note that we can also find empty spots via no blocks, because we rerelocate them from the field copy as soon as we inspect them. In this case we just go on via the following block in the area.

We now want to react to the signal and display screen a window with the player score and also a "play again"-button as soon as a gameover occurs. Let"s include a brand-new file GameOverWindow.qml.


import carolannpeacock.com 3.0 import QtFast 2.0 Item id: gameOverWindow width: 232 height: 160 // hide when opacity = 0 visible: opacity > 0 // disable when opacity enabled: opacity == 1 // signal once brand-new game button is clicked signal newGameClicked() Image source: "../assets/GameOver.png" anchors.fill: parent // display screen score Text // collection font font.family: gameFont.name font.pixelSize: 30 color: "#1a1a1a" text: scene.score // set position anchors.horizontalCenter: parent.horizontalCenter y: 72 // play again switch Text // set font font.family: gameFont.name font.pixelSize: 15 color: "red" text: "play again" // set place anchors.horizontalCenter: parent.horizontalCenter anchors.bottom: parent.bottom anchors.bottomMargin: 15 // signal click occasion MouseArea anchors.fill: parent onClicked: gameOverWindow.newGameClicked() // this computer animation sequence alters the shade of message in between red and orange infinitely SequentialAnimation on color loops: Animation.Infinite PropertyAnimation to: "#ff8800" duration: 1000 // 1 second for fade to oarray PropertyAnimation to: "red" duration: 1000 // 1 second for fade to red // reflects the home window function show() gameOverWindow.opacity = 1 // hides the home window feature hide() gameOverWindow.opacity = 0 The home window consists of an image, the player score and also a "play again"-button that is currently animated by combining a SequentialAnimation with two PropertyAnimations. In addition, the window likewise emits a signal when the button is clicked. We have the right to open up or cshed this home window by calling the show- or hide-function. Keep in mind that just the opacity is collection accordingly in these features. We then use building bindings choose visible: opacity > 0 and also enabled: opacity == 1 to:

Only allow interactions choose a click of the button once the home window is fully visible. Completely hide the window as soon as its opacity is zero. This permits us to fade the home window in or out at a later on suggest by animating the opacity, without any kind of issues around it still being active in the background.

We deserve to include this window to our scene via simply a few lines of code.


import carolannpeacock.com 3.0 import QtFast 2.0 GameWindow id: gameWindow // ... Scene id: scene // ... GameArea id: gameArea anchors.horizontalCenter: scene.horizontalCenter y: 20 blockSize: 30 onGameOver: gameOverWindow.show() // configure gameover window GameOverWindow id: gameOverWindow y: 90 opacity: 0 // by default the home window is covert anchors.horizontalCenter: scene.horizontalCenter onNewGameClicked: scene.startGame() // initialize game function startGame() gameOverWindow.hide() gameArea.initializeField() scene.score = 0 We added the GameOverWindow and applied the handler onNewGameClicked to start a new game. We then set the onGameOver handler in our GameArea-object to present the home window and also hide it aget once the startGame-function is referred to as.

Hit play and enjoy your completely playable Juicy Squash game!

Polishing the Game

The game still feels a tiny little bit stiff. We have to usage animations to fade out the blocks when rerelocating them and actually let the fruits fall dvery own from over. Let"s start with preparing the animations in our Block.qml.


EntityBase id: block entityType: "block" // hide block if exterior of game location visible: y >= 0 // ... // fade out block before removal NumberAnimation id: fadeOutAnimation target: block property: "opacity" duration: 100 from: 1.0 to: 0 // rerelocate block after fade out is finiburned onStopped: entityManager.removeEntityById(block.entityId) // computer animation to let blocks loss down NumberAnimation id: fallDownAnimation target: block property: "y" // timer to wait for other blocks to fade out Timer id: fallDownTimer interval: fadeOutAnimation.duration repeat: false running: false onTriggered: fallDownAnimation.start() // begin fade out / removal of block feature remove() fadeOutAnimation.start() // cause fall dvery own of block attribute fallDown(distance) // finish previous autumn before founding a new one fallDownAnimation.complete() // relocate through 100 ms per block // e.g. moving down 2 blocks takes 200 ms fallDownAnimation.duration = 100 * distance fallDownAnimation.to = block.y + distance * block.height // wait for removal of other blocks prior to falling dvery own fallDownTimer.start() Keep in mind that we set visible: y >= 0 to hide the freshly produced fruits that will be placed exterior of the game area. They will certainly immediately display as soon as their computer animation moves them right into the game location. We then use two NumberAnimations to realize the fade-out and also the movement of the fruits. Before any block starts relocating, it should wait for the fade-out of various other blocks in the game. To accomplish this we usage a Timer and also collection the fade-out duration as its interval. We are going to begin the movement after that time has actually passed.

We deserve to currently use the fallDown- and remove-functions to animate the fruits:

The remove-function fades out the block and removes the entity from the game once the computer animation is finimelted. The fallDown-feature waits some time till the rerelocating of other blocks in the grid is finimelted and then moves the block dvery own by a certain distance.

Let"s use them within the removeConnectedBlocks- and moveBlockToBottom-functions of our game location.


Item id: gameArea // ... // remove previously noted blocks feature removeConnectedBlocks(fieldCopy) // search for blocks to remove for(var i = 0; i fieldCopy.length; i++) if(fieldCopy === null) // rerelocate block from field var block = gameArea.field if(block !== null) gameArea.field = null block.remove() // relocate staying blocks to the bottom and also fill up columns with brand-new blocks feature moveBlocksToBottom() // check all columns for empty fields for(var col = 0; col columns; col++) // start at the bottom of the field for(var row = rows - 1; row >= 0; row--) // discover empty field if(gameArea.field === null) // uncover block to relocate dvery own var moveBlock = null for(var moveRow = row - 1; moveRow >= 0; moveRow--) moveBlock = gameArea.field if(moveBlock !== null) gameArea.field = null gameArea.field = moveBlock moveBlock.row = row moveBlock.fallDown(row - moveRow) break // if no block discovered, fill entirety column up through new blocks if(moveBlock === null) var distance = row + 1 for(var newRow = row; newRow >= 0; newRow--) var newBlock = createBlock(newRow - distance, col) gameArea.field = newBlock newBlock.row = newRow newBlock.fallDown(distance) // column currently filled up, no should check better rows again break // end inspect rows starting from the bottom // finish check columns for empty areas // ... The removeConnectedBlocks-function currently offers the new remove-attribute of the block. In the previous variation of the function, we directly removed it with the entity manager.

When we relocate a block to the bottom or develop brand-new blocks, we ssuggest use the fallDown-feature rather of altering the y-place of the blocks. Keep in mind that once we produce brand-new blocks, we now place them external of the game area by setting newRow - distance as the initial grid place at the createBlock-speak to.

We have the right to watch the fruits fall dvery own now, pretty cool! But at this suggest it would certainly be possible to click and rerelocate blocks while they are fading out or moving dvery own. We desire to neglect these signals to stop unwanted behavior that might occur as soon as we try to readjust the field while the previous changes aren"t completed yet. For this purpose we will include a role to inspect if the area is ready.


Item id: gameArea // ... // take care of user clicks function handleClick(row, column, type) if(!isFieldReadyForNewBlockRemoval()) rerevolve // ... // ... // retransforms true if all animations are finished and brand-new blocks might be rerelocated attribute isFieldReadyForNewBlockRemoval() // check if optimal row has empty spots or blocks not fully within game location for(var col = 0; col columns; col++) var block = field if(block === null // area is prepared rerotate true If the area is not all set yet, we disregard all clicked-occasions in our handler function. The fieldIsReady()-feature just returns true once eincredibly spot in the initially row of the grid is filled with a block, that has finimelted relocating into the game area.

That"s all we should disregard clicks while we fade out and move our fruits. To finish the animations for our game, we likewise let the gameover-home window fade in and out by specifying a Behavior on the opacity property.


Item id: gameOverWindow // ... // fade in/out computer animation Behavior on opacity NumberAnimation duration: 400 // ... This is as far as we go in regards to animations.

Increasing Difficulty

When we play the game now, it might be over real quick because there are so many different fruit types on the area initially. This renders it incredibly most likely to run out of matches pretty shortly. We deserve to counter that by starting through fewer fruits and include various other kinds later during the game. We simply have to introduce some additional properties in our game area and use them appropriately.


Item id: gameArea // ... // properties for increasing game challenge residential property int maxTypes residential property int clicks // ... feature initializeField() // recollection challenge gameArea.clicks = 0 gameArea.maxTypes = 3 // ... // produce a brand-new block at particular place feature createBlock(row, column) // connumber block var entityProperties = width: blockSize, height: blockSize, x: column * blockSize, y: row * blockSize, type: Math.floor(Math.random() * gameArea.maxTypes), // random kind row: row, column: column // ... // take care of user clicks function handleClick(row, column, type) // ... if(blockCount >= 3) // ... // rise challenge eincredibly 10 clicks until maxTypes == 5 gameArea.clicks++ if((gameArea.maxTypes 5) && (gameArea.clicks % 10 == 0)) gameArea.maxTypes++ // ... We define 2 brand-new properties maxTypes and also clicks to organize the number of currently obtainable forms and also the variety of effective moves the player made. We recollection these properties every time we initialize the area. The random kind of a new block is then based on the maxTypes building. After each effective player relocate, we increase the click respond to and based upon that we might additionally boost the maximum number of types. We made a decision to start through only 3 fruit forms and include a new type after eincredibly 10th effective move, until we reach our maximum number of forms.

Congratulations, you simply completed this tutorial for the match-3 game Juicy Squash! Of course, you are welcome to incorporate your very own ideas, include some twists to the game or produce your own match-3 game based upon this one.

What Comes Next?

The game is still doing not have some significant features, you can:
