  1. couple of questions

    var game = new Phaser.Game(1024,768,Phaser.AUTO, 'space game', {preload: preload, create: create, update: update}); var ships; var ship; function preload(){ game.load.image('spaceship', 'assets/spaceship_sprite.png'); game.load.image('menu', 'assets/menu.png'); } function create(){ ship = game.add.sprite(500,680, 'spaceship'); game.physics.arcade.enable(ship); ship.scale.setTo(0.5,0.5); //ship2 = myship(game, 'spaceship', 600, 200); ships = game.add.group(); for (var i = 0; i < 0; i++){ //var sx = 100; ships.create(600, 200, 'spaceship'); //myship(game, 'spaceship', 500+sx, 200); //sx += 100; //game.add.sprite(500, 200, 'spaceship'); } cursors = game.input.keyboard.createCursorKeys(); pauseKey = game.input.keyboard.addKey(Phaser.Keyboard.ONE); pauseKey.onDown.add(addMenu, this); game.input.keyboard.removeKeyCapture(Phaser.Keyboard.ONE); } function update(){ if(cursors.left.isDown){ ship.body.x += -7; } if(cursors.right.isDown){ ship.body.x += 7; } } function addMenu(){ game.add.sprite(100,100,'menu'); } 1. I want to add a few sprites of a ship into the 'ships' group. But for loop doesn't work. I'm folowing this example: https://phaser.io/examples/v2/groups/add-a-sprite-to-group#gv even If I try to add object from external script. I've tried to create a few ships of 'myship' without the 'for loop' and it works fine. 2. If I uncomment this line: //ship2 = myship(game, 'spaceship', 600, 200), my 'ship' doesn't move (key input doesn't work). What am I doing wrong? Sorry for my poor english.
  2. Help with Matrix algorithm

    I need some help to optimize algorithm. I have a matrix of sprites and I am highlighting a part of it. It can be rectangle or square it doesn't matter. I need to hide all sprites of this matrix that do not belong to the given area. I have this function which is highly non-optimized i.e 4 nested "for" cycles: hideMatrixArea: function(slotTwoDimArray, row, col, numRows, numCols) { var i = 0, j = 0, k = 0, t = 0, matrixWidth = slotTwoDimArray.length, matrixHeigth = slotTwoDimArray[0].length; for (i = 0; i < matrixWidth; i += 1, k += 1) { for (j = 0; j < matrixHeigth; j += 1, t += 1) { for (k = row; k < row + numRows; k += 1) { for (t = col; t < col + numCols; t += 1) { if (!(k === i && t === j)) { console.log("hello"); this.hideSlot(slotTwoDimArray, i, j); } } } } } return slotTwoDimArray; }, It prints "hello" 15600 times which is a lot. How can I hide slots that are not in the space (row, col) -> (row + numRows, col + numCols) i.e the inverse without using nested "for" loops? Any ideas?
  3. Got some problem with my item inventory in my game

    I'm trying to make a silly RPG in phaser.js, right now I am working on the battle system and the battle menus. However there is a problem with the item inventory. I have made so that the texts for the names of the items that are in my inventory appear when I open the inventory and disappear when I close it or after I have used an item (and then I delete that item using splice since all the items are in a list). However, when I use an Item, the text for the name of that item does not disappear in the inventory when I open it again (but I cannot use the item at least). And also, the text for the name of the last item in the list stays on the sceern even when I haven't open the inventory. First i thought it was because the for-loop I use to create all the "name texts" for all items in the list was in the create function, but I tested puting it in the update function but it didn't change anything. I just want a simple item inventory that you find in almost every RPG. Can someone please help me with this? Some variabels in the code are on swedish.
