I was posting this thread at the wrong place (it was in Phaser 2). OK, I am having a very bad time with clickable objects. It works perfectly on desktop browser but when I run it on my Android mobile the hot spot is totally off. Please refer to the attached picture to have an idea what I am talking about. The blue square is the clickable object (it's a .png picture). Tapping the object won't fire the input event but if I tap around the position where I draw the marquee it will. In other words, the clickable area is off of the picture. I found this thread where the OP had a similar issue and mentioned that is could be related to the mobile devicePixelRatio when using Phaser.CANVAS but I couldn't establish a coherent relationship between the DPR and the displacement (otherwise it could be "compensated" with code). I really cannot see how to solve this. I am about to give up Phaser and try a different engine. Any idea?

OK, this is weird. I spent a lot of time trying to figure out why my image objects wasn't firing when I tapped on it (it works on desktop). After several tests I noticed that it happened that on mobile screen the clickable area was off of the image (displaced). I found that someone had a similar issue and figured that it had something to do with devicepixelratio when using Phaser.CANVAS. I couldn't test with Phaser.AUTO because my mobile throws a WebGL error when I try to use it. Any idea how to fix this issue? Thanks!

I am creating a Bejeweled game using Emanuele Feronato's awesome prototype; Match 3 Bejeweled HTML5 prototype made with Phaser – detecting combos. I created my own grayscale graphics in Photoshop, made them a little bigger, increased the grid size of the game, and used some code from his HTML5 Dungeon Raid tile engine made with Phaser – Part 4 tutorial to make the game scalable. I used Phaser's sprite tint property to color my jewels. They look awesome all randomly colored like that, but it is difficult to make matches on just shape alone. How would you tint specific frames a certain color? I will have made a great leap forward in my game when it can do the following: Select seven out of 13 color options Select seven out of 49 sprites in the Jewels spritesheet. I used the same layer style in this original. It doesn't look bad, but I think different styles of jewel as well as having the shapes all tinted the same color will make matches easier to see. The sprites should all be from different columns. For example, if the first sprite selected was the star in the top left corner of the image, the next frame should be a hexagon or other shape from a different row. Once the different frames have been chosen, the game should apply the chosen colors to to the chosen frames of my spritesheet. I have attached my code. I appreciate any help you can give. Thank you all very much! CatsTreasures.zip

I'm working on a game and I'm trying to implement dynamic resizing, but I have some unexplained issues. My game is optimized for a phone portrait layout. Depending on the phone screen size (or browser window size) it should adjust the layout, the width is fixed size but the height is adjusted. So make it taller if necessary and center some sprites or texts. I've created a code example which works, but the resize function gets called many times. So to isolate and test the resize function see this github example: https://github.com/BdR76/phaserresize/ The code example has 4 states: Boot, Preloader, MainMenu, Game. I won't post all the code here, but what I've done is essentially this: // Boot state, in create() setup the scale.setResizeCallback event handler. mygame.Bootup.prototype = { create: function(){ this.game.scale.setResizeCallback(this.resizeCallback, this); this.game.scale.onSizeChange.add(this.onSizeChange, this); }, resizeCallback: function(manager) { // browser window changes size, resize the game var ratio = window.innerHeight / window.innerWidth; if (GAME_WIDTH * ratio > GAME_HEIGHT) { this.scale.setGameSize(GAME_WIDTH, Math.floor(GAME_WIDTH * ratio)) // too tall, adjust height resolution } else { this.scale.setGameSize(GAME_WIDTH, GAME_HEIGHT); // too wide, just use fixed width and empty side bars }; }, onSizeChange: function() { // fire the game resize event for the current state (make sure each state has this) this.game.state.callbackContext.resize(); } }; And then both the MainMenu and Game have a resize function that adjusts its layout and positions of sprites, text etc., it's a little similar to this topic. My github code example works, however the resizeCallback function from the Bootup state gets called all the time. It fires many times right from the beginning even before I do anything. I'm not resizing and not switching state or anything, and it get called not once but continually. So my questions is: Why is the onSizeChange event called so often? Is this normal and should I use a different event?

Note5 or Galaxy S6 has devicePixelRatio of 4, how do you guys handle different image to be responsive to all the different device aspect ratio and devicePixelRatio?

Hi guys, I'm having a slight problem getting my head round using the Phaser.RESIZE scale mode with devices which have a higher pixel ratio than 1. The game resizes fine, but on modern iOS and android devices, the game loses its 'crispness', and objects become blurry, particularly smaller text. I know this is down to higher pixel densities of these devices, but I've not managed to find a solution for the canvas to utilise these extra pixels, as resize mode seems to be bound to the physical document dimension (I'm creating a responsive game which will fill the device/webpage window on either orientation, so sadly the SHOW_ALL approach won't work). Just wondering if anyone had uncovered any solution, or had any advice, as there doesn't seem to have been any conclusion on other similar posts. Thanks as always!

Hello, we develop a new side-scrolling platform game, is about a car that jump different obstacles and uses turbo (nitrous like need for speed). We are going to use 2 main buttons, for jump and accelerate with turbo, register mouse listener and mapping them to touch listener in case we detect a touch device (moderniz library for example). We construct the game under 480x320 resolution, we use a main div scale 100% to the screen and centered canvas that scale width ratio (480x320). And are going to use two group of images, low res and high res and load them. We need recomendations. our idea is correct??? what resolution or width of the screen we use to select low resolution and high resolution? what image resolution we could use for high resolution? Any opinion will be apreciated.
