  1. I get a syntax error Uncaught SyntaxError: Unexpected token : in the console when I load my tiled json maps. Everything runs fine, my maps are loaded correctly, but why does it give this error? json looks like: { "height":32, "layers":[ { "data":"AAAAAAAAAA" etc. I understand that there's no var declared at the beginning of the object, but it's saved as a json file and loaded as a json file. Why give this error? Just wondering. Thanks,
  2. Hi, I'm trying to get a sprite to spawn within a polygon I've drawn in Tiled. I've imported the polygon like so: this.bunyipSpawnZone = new Phaser.Polygon(polygonSpawn[0][0],polygonSpawn[0][1],polygonSpawn[1][0], polygonSpawn[1][1],polygonSpawn[2][0],polygonSpawn[2][1],polygonSpawn[3][0], polygonSpawn[3][1],polygonSpawn[4][0],polygonSpawn[4][1],polygonSpawn[5][0],polygonSpawn[5][1]); polygonSpawn is the corresponding Tiled map object. Which is an array where [0] is the x coord and [1] is the y. this.bunyipSpawnZone returns a Phaser.Polygon with seemingly appropriate x and y coordinates. Phaser.Polygon_points: Array[6]0: Phaser.Pointtype: 25x: 158y: -6__proto__: Object1: Phaser.Pointtype: 25x: 20y: -852__proto__: Object2: Phaser.Pointtype: 25x: 902y: -852__proto__: Object3: Phaser.Pointtype: 25x: 892y: -996__proto__: Object4: Phaser.Pointtype: 25x: -96y: -978__proto__: Object5: Phaser.Pointtype: 25x: -114y: 0__proto__: Objectlength: 6__proto__: Array[0] area: -300120 closed: true flattened: false points: (...)type: 12 But the area is negative??? Why is that? And I can't seem fill in the area with graphics.beginFill() to verify that the polygon is in the right place. I tried using .contains for debugging as well, but that's also not giving me a true when I expect it to. Again the end goal here is to have an enemy spawn somewhere randomly in the polygon. But it seems I can't get a polygon working right. the github is https://github.com/nodes777. Any help would be appreciated. Thanks!
  3. Hmm yea this is weird. Try <html> <head> <meta charset="UTF-8" /> <meta name=viewport content="width=device-width, initial-scale=1"> <link rel="icon" href="favicon.png" /> <title>Test</title> <script src="https://github.com/photonstorm/phaser/releases/download/v2.6.2/phaser.js"></script> <style> .game{ position: relative; } .text{ position: relative; } </style> </head> <body> <div id="game" class="game"></div> <span class="text">hi</span> </body> </html> Then, what browser are you using? And then as a last resort you can manually set that span class to position: absolute; top: 800px; <!--AKA the height of the game-->
  4. Can you put it in a codepen or paste the full code as text and I can take a look at it?
  5. Hey @samme Thanks so much for taking the time to look at my project and contribute to it! I think I'll be taking the 2 game states route, just as a separation of concerns. Thank you again!
  6. Hi @samme thanks for the reply. Right, so since init and create are run each time, should I try to implement the miniGame within game.js and not in its own state? I'm looking through those docs now. Thanks for the direction. You're right about adding duplicate objects, if I run the miniGame many times over the whole game starts to chug with a dwindling framerate.
  7. When I run them outside of the init function, they work exactly as intended.
  8. Hi @plicatibu, Thanks for the answer! That's what I'm doing now, however something's not working. Functions written after init aren't being called in init. this.displayFish(fish); and this.addFishToInventory(fishCopy); are both not running properly, but I'm also not getting an error init: function(caughtFish, fishOnLine) { if (caughtFish != null || undefined && caughtFish) { var fish = fishOnLine; console.log('caught a ' + fish.name); //show the fish on screen above player this.displayFish(fish); //add a copy of the fish to player's inventory var fishCopy = new this.Fish(fish.name, fish.size, fish.price); this.addFishToInventory(fishCopy); } else if (caughtFish != null || undefined && !caughtFish){ console.log('no fish, sorry man'); } }, Where am I going wrong?
  9. Hi all, I'm trying to get a handle on using states correctly. I'm creating a fishing game, which has an over-world you walk around in, and can approach different bodies of water. Once you get near one you can press space to fish. I then start a new state, which will be a mini-game where you try to catch the fish. Then I want to return to the over-world with a successful (or not) catch. Right now, I can start the mini-game phase (miniGame.js), passing in the fish to catch, but when I return to the overworld (Game.js), I can't display the fish or add it to the inventory, because I'm trying to do this in the init function, which requires functions that are defined later in phaser. the player character's position is also reset because create runs right after init. I don't need to run everything in create again right? Because I've already created the map and sprites. Looking at the docs for the phaser state manager, I'm doing: this.state.start('miniGame', false, false, fishOnLine); where the two booleans are for not clearing the world and not clearing the cache, I thought that this would make it easier to return to game state. The fishOnLine contains data about the fish to be caught. After the miniGame I try to return to the Game with the following: this.state.start('Game', false, false, caughtFish, this.fishOnLine); caughtFish is a boolean for if the catch was successful. For now I haven't made the miniGame, and I always return it true. this.fishOnLine is the same fish data as fishOnLine from before. But when the Game state starts, the player's position is reset, and the inventory and display functionality don't work or throw an error. Nothing happens. What am I missing? How can I fluidly transition between two states? Most state examples show you how to add a top score to a title screen, but I need to be able to not reset the game when returning to it. Below is my code for the two game states, the cull code can be seen here Game.js: var TopDownGame = TopDownGame || {}; //title screen TopDownGame.Game = function() {}; TopDownGame.Game.prototype = { init: function(caughtFish, fishOnLine) { if (caughtFish != null || undefined && caughtFish) { var fish = fishOnLine; this.makeFlowersDance(); console.log('caught a ' + fish.name); //show the fish on screen above player this.displayFish(fish); //add a copy of the fish to player's inventory var fishCopy = new this.Fish(fish.name, fish.size, fish.price); this.addFishToInventory(fishCopy); } else if (caughtFish != null || undefined && !caughtFish){ console.log('no fish, sorry man'); } }, create: function() { this.map = this.game.add.tilemap('beach'); //the first parameter is the tileset name as specified in Tiled, the second is the key to the asset this.map.addTilesetImage('basicTiles', 'gameTiles'); //create layers this.backgroundlayer = this.map.createLayer('background'); this.blockedLayer = this.map.createLayer('blockedLayer'); //console.log(this.blockedLayer); //console.log(this.blockedLayer._results); console.log(fishJSON); //create yellow flowers group this.yellowFlowers = this.game.add.group(); for (var i = 0; i < 5; i++) { this.yellowFlowers.create(this.game.rnd.integerInRange(0, 400), this.game.rnd.integerInRange(100, 300), 'yellowFlower', 0);

  10. I'm trying to create a "zone" around body's of water where a player can fish. To do so, I'm using tiled and drawing a rectangle object around the bodies of water. This "zone" ideally is invisible, but could also just be tiles. I'm trying to use the createFromObjects() method on my map. I'm following the phaser example, and looking at the docs. One of the required parameters is the gid. However my json export simply does not contain a gid property. It has an id for the objects, which I've tried to use, and I've even created the gid manually by typing it into the json. However both of these just create objects with 0 width and height. What am I doing wrong? How do get objects from Tiled into phaser? I'm also open to trying createFromTiles to accomplish this goal or any other advice.
