    Help with Buttons

    You absolute genius, I knew it would be a simple error, I suppose that's what I get for using parts of other peoples code . I get a different error now relating to my game over state, but I'll try and solve that myself. Thank you so much samme!!

    Yep happens as soon as the state loads. It also creates 2 smaller weird windows below the actual game, but I think that’s a separate issue

    Absolutely. I'll warn you now though, its quite long and this is just the final state in my game to ask the user maths questions. Also the localstorage stuff is just there from when I was messing around earlier. I hope my comments makes sense too. var Questions, Phaser, game, localStorage; var gameOptions = { // maximum length of the sum maxSumLen: 5, // local storage name used to save high score localStorageName: "oneplustwo", // time allowed to answer a question, in milliseconds timeToAnswer: 4000, // score needed to increase difficulty nextLevel: 400 }; // "PlayGame" state var Questions = { // when the state preloads... preload: function(){ // making the game cover the biggest window area possible while showing all content game.scale.scaleMode = Phaser.ScaleManager.SHOW_ALL; // game.scale.pageAlignHorizontally = true; // game.scale.pageAlignVertically = true; // do not pause the game when it loses focus game.stage.disableVisibilityChange = true; // preloading images game.load.image("timebar", "./assets/images/timebar.png"); // preloading a spritesheet where each sprite is 400x50 pixels game.load.spritesheet("buttons", "./assets/images/buttons.png", 400, 50); }, // when the state has been created... create : function() { // create Questions state and start it game.state.add("Questions", Questions, true); // create a 500x500 pixels game using CANVAS rendering Questions = new Phaser.Game(500, 500, Phaser.AUTO); game.stage.backgroundColor = '#0D0D73'; // it's not game over yet... this.isGameOver = false; // current score is set to zero this.score = 0; // we'll also keep track of correct answers this.correctAnswers = 0; // topScore gets the previously saved value in local storage if any, zero otherwise this.topScore = localStorage.getItem(gameOptions.localStorageName) == null ? 0 : localStorage.getItem(gameOptions.localStorageName); // sumsArray is the array with all possible questions this.sumsArray = []; // rather than tossing a random question each time, I found easier // to store all possible questions in an array then draw a random question // each time. I just need an algorithm to generate all possible questions. // let's start building all possible questions with this loop // ranging from 1 (only one operator, like 1+1) to maxSumLen // (in this case 5, like 1+1+1+1-1-1) for(var i = 1; i < gameOptions.maxSumLen; i++){ // defining sumsArray[i] as an array of three empty arrays this.sumsArray[i]=[[], [], []]; // looping from 1 to 3, which are the possible results of each sum for(var j = 1; j <= 3; j++){ // buildTrees is the core of the script, see it explained // some lines below this.buildThrees(j, 1, i, j); } } // try this! You will see all possible combinations console.log(this.sumsArray); // questionText is the text object which will display the question this.questionText = game.add.text(250 , 160, "-", { font: "bold 72px Arial" }); // setting questionText registration point this.questionText.anchor.set(0.5); // scoreText will keep the current score this.scoreText = game.add.text(10, 10, "-", { font: "bold 24px Arial" }); // loop to create the three answer buttons for(i = 0;i < 3; i++){ // creation of the answer button, set to frame "i" // Calls checkAnswer callback function once triggered game.add.button(50, 250 + i * 75, "buttons", this.checkAnswer).frame = i; } // adding the time bar var numberTimer = game.add.sprite(50, 250, "timebar"); // creation of a graphic mask covering the three answer buttons this.buttonMask = game.add.graphics(50, 250); this.buttonMask.beginFill(0xffffff); this.buttonMask.drawRect(0, 0, 400, 200); this.buttonMask.endFill(); numberTimer.mask = this.buttonMask; // method to ask next question this.nextNumber(); }, // buildThrees method, it will find all possible sums // arguments: // initialNumber: the first number.

    I also looked at how my create was defined above, but I've called it the same thing everywhere I need to reference it, no typos or anything from what I can see, just really stumped as to what I've done wrong.

    I had a good look at that and all I could see was that the function call is optional, but I don't think I've done anything wrong there as far as I can tell.

    Basic Troubleshooting Help

    Yeah I have a checkAnswer function, here's the code for it checkAnswer: function(button){ if(!this.isGameOver){ if(button.frame == this.randomSum){ this.score += Math.floor((this.buttonMask.x + 350) / 4); this.correctAnswers++; this.nextNumber(); } // wrong answer else{ if(this.correctAnswers > 1) { this.timeTween.stop(); } this.gameOver(button.frame + 1); } } },

    Basic Troubleshooting Help

    Hi, I'm a relative noob to javascript and Phaser, and I'm having an issue coding my first proper game. I'm using Phaser version 2.6.2 and the latest version of Chrome browser. I'm asking the user a basic maths question, but when I draw the buttons for the user to click they appear but aren't clickable. Here is the console error: And here is the code I believe to be causing the error: game.add.button(50, 250 + i * 75, "buttons", this.checkAnswer).frame = i; And there is also this bit of code to draw the button mask: this.buttonMask = game.add.graphics(50, 250); this.buttonMask.beginFill(0xffffff); this.buttonMask.drawRect(0, 0, 400, 200); this.buttonMask.endFill(); numberTimer.mask = this.buttonMask; Any help would be appreciated, if you need any extra information to help me I'll gladly provide it. Been staring at this problem for over a week and I just can't figure out what's wrong, I hope it's something simple I'm doing wrong. Thanks
