callidus Posted August 22, 2014 Share Posted August 22, 2014 I'm trying to spawn a randomly coloured block and to do so I am using math.random and the console says everything is loading but the assets aren't loading. There are no errors in it but can anyone find an error that might be causing the assets not to load? Parts of the code that's relevant is coloured green. Thanks for any help. My Code: var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create, update: update,});var x = Math.floor(Math.random () * 800); // ball spawns in a random placevar y = Math.floor(Math.random() * 600);var text; var colour = Math.random() * 3;function preload() {cursors = game.input.keyboard.createCursorKeys(); //allows keyboard inputthis.game.load.image("block","assets/block.png");this.game.load.image("redBlock","assets/red.png");this.game.load.image("greenBlock","assets/green.png");this.game.load.image("blueBlock","assets/blue.png");} function create() {this.game.physics.startSystem(Phaser.Physics.ARCADE);this.game.scale.pageAlignHorizontally = true; //centers canvasthis.game.scale.pageAlignVertically = true;this.game.scale.refresh(); block = this.game.add.sprite(x,y,"colour"); // x and y are randomy coordinates the ball spawns atthis.game.physics.arcade.enable(block);block.body.velocity.setTo(200,200);block.body.collideWorldBounds = true; block.body.bounce.set(1); player = this.game.add.sprite(10,10,"block");this.game.physics.arcade.enable(player);player.scale.setTo(0.2,0.2);player.body.collideWorldBounds = true;} function update() { player.body.velocity.x = 0;player.body.velocity.y = 0; if(colour < 1){colour = "redBlock";} if(colour < 2){colour = "blueBlock";} if(colour < 3){colour = "greenBlock";} if(cursors.left.isDown){player.body.velocity.x += -200; } if(cursors.right.isDown){player.body.velocity.x += 200;} if(cursors.down.isDown){player.body.velocity.y += 200;} if(cursors.up.isDown){player.body.velocity.y += -200;}} Link to comment Share on other sites More sharing options...
Dumtard Posted August 22, 2014 Share Posted August 22, 2014 You are adding a sprite with the key "colour" but loading in no image with that key, you have "block", "redBlock", "greenBlock", and "blueBlock". Change the line to this.block = this.game.add.sprite(x,y,"redBlock"); // x and y are randomly coordinates the ball spawns atand you will see the block displayed. An easy fix for what you want would be to generate a random number and add the sprite based on that. var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create, update: update});var cursors;function preload() { this.game.load.image('block', 'assets/block.png'); this.game.load.image('redBlock', 'assets/red.png'); this.game.load.image('greenBlock', 'assets/green.png'); this.game.load.image('blueBlock', 'assets/blue.png');} function create() { this.game.physics.startSystem(Phaser.Physics.ARCADE); this.game.scale.pageAlignHorizontally = true; this.game.scale.pageAlignVertically = true; this.game.scale.refresh(); cursors = game.input.keyboard.createCursorKeys(); var x = Math.floor(Math.random() * 800); var y = Math.floor(Math.random() * 600); var colours = ['redBlock', 'greenBlock', 'blueBlock']; //Access random index from [0..2] in colours array var colour = colours[Math.round(Math.random() * 2)]; //Add sprite based on colour selected from colours array var block = this.game.add.sprite(x, y, colour); this.game.physics.arcade.enable(block); block.body.velocity.setTo(200, 200); block.body.collideWorldBounds = true; block.body.bounce.set(1); var player = this.game.add.sprite(10, 10, 'block'); this.game.physics.arcade.enable(player); player.scale.setTo(0.2, 0.2); player.body.collideWorldBounds = true;} function update() { player.body.velocity.setTo(0); if(cursors.left.isDown) { player.body.velocity.x += -200; } if(cursors.right.isDown) { player.body.velocity.x += 200; } if(cursors.down.isDown){ player.body.velocity.y += 200; } if(cursors.up.isDown){ player.body.velocity.y += -200; }} callidus 1 Link to comment Share on other sites More sharing options...
