Hi, I have problem with phaser performance. The phaser CPU usage is too high. Configuration : - game is on phaser 3 with vue - main page is on vue with game in iFrame this.gameInstance = new Phaser.Game({ width: properties.width, height: properties.height, resolution: PIXEL_RATIO, "callbacks.postBoot": function() { document.getElementsByTagName("canvas")[0].style.width = properties.width + "px" document.getElementsByTagName("canvas")[0].style.height = properties.height + "px" }, scaleMode: 0, type: Phaser.CANVAS, parent: document.getElementById('game'), title: '☕️ Brunch with Phaser and ES6', // 'My Phaser 3 Game' url: 'https://github.com/samme/brunch-phaser-es6', version: '0.0.1', banner: { background: ['#e54661', '#ffa644', '#998a2f', '#2c594f', '#002d40'] }, fps: { min: 10, target: 60, forceSetTimeout: true, }, loader: { path: 'static/phaser/', }, physics: { default: 'arcade', arcade: { debug: false, gravity: { y: 300 }, }, }, scene: [ LoaderScene, BootScene, DefaultScene, GameOverScene, ], }); CPU usage: - Phaser = 40% - Phaser with vue = 80-90% - main page without iframe = 5-10 % - main page with iframe = 100% js heap size: - Phaser = 50 - 70 MB - Phaser with vue ~ 70 - 100MB - main page without iFrame ~ 50 - 80 MB - main page with iFrame ~ 100 - 150 MB The game is equipped with 20-30 icons, 10 atlases, 19 mp3 sounds and 5 background image, with total size of assets about 3MB. Thank you in advance

Hi Thanks for the great BJS and TOB exporter, the meshes could be generated from Blender and rendered in BJS environment efficiently. However I find out something interesting that JS heap increases when the mesh is instanced in the scene. But the heap size could not be decreased when the mesh is disposed. I’m curious whether this will cause some memory issues(such as memory leak). Here is the demo of the system: https://willlinifm.github.io/Playground_bjs/index.html The Source code is as the following or the link : https://willlinifm.github.io/Playground_bjs/js/Scene.js If the playground is better for debugging, please try this link. The implementation and the outcome are nearly the same. (Click Sphere to generate mesh //// Click ground to dispose it) https://www.babylonjs-playground.com/#4GQCEL#2 The attachment are the heap snapshots ! 。The heap1 snapshot is took before the mesh is made an instance by TOB-generated-js file 。The heap2 heap snapshot is took after the mesh is made an instance by TOB-generated-js file. We can find that the heap size is increased. 。The heap3 snapshot is somehow hard to understand that when the mesh dispose function is called, the heap size still raise a high level compared to the first snapshot. NO~~ My questions are 1. If the meshes are generated and the Js heap size is increasing at the same time. Will it cause the memory issue and make the system run slowly? 2. How to make the best to decrease the heap size after mesh dispose process. 3. I’m not sure, but during watching the snapshot constructor information, I find there may be some looping references within BJS/TOB/MeshFactory structure. Will it cause the GC(Garbage Collection) unable to release memory? Thank you ! BJS and everything here are awesome!

Hi guys, I've been running profiles in Chrome dev tools on my game but having trouble making things run faster. I realize this is a hard question to ask, but can anyone point me in a direction of things to try? Play/test here: http://daverau.info/play/leafy-mobile/ - the game world is 50k pixels wide platform type game And uses arcade physics for Gravity - all assets are png retina so I'm scaling for high dpi but that doesn't seem to add my overhead - particle emitter is lightweight and doesn't seem to impact performance - I have about 500 platforms that all run collide checks, is there a way to only collide check what's in the camera view? - how can I better isolate what's causing memory leaks and max CPU performance? thanks for any help you can offer! I know it's hard to debug someone else's game but hoping for pointers.

Hello, this is my first post I'm a beginner when it comes to game dev, but hopefully I'll get better by the time. In my first effort to understand Phaser, I followed the great tutorial Extreme Walking Simulator, and fine so far. But I noticed a high CPU-usage for process System, Kernel. It is happening even at the title screen where no particular action is triggered. Then I searched for other Phaser-games, found i.e. https://www.codeandweb.com/blog/2015/10/07/phaser-p2-physics-example-tutorial and this pushes the CPU up to about 17-20%. Can I do anything to avoid the high CPU-usage when developing my first game?, I'm thinking of wrong patterns here, not intended use etc. Cheers Janus

Hi everyone, I need your help to understand advanced behaviors in Phaser. We're developing a big game with Phaser, we have many sprites, many layers and many animations. We have texts, and transparency too. Everything we need to make the game slow and with poor FPS We want to optimize the game one step after another, and we want to understand, too, what is the most consuming task. The game is currently running at 40 to 50 FPS on a desktop, with some minor slowdowns, but that is ok for us. On a mobile phone, even with big hardware (iPhone 5s, Xperia Z1, HTC One M8), it runs at 2 to 10 FPS, unplayable. The strange thing is that we tried to run the game on the iOS simulator, to profil it, and the result was exactly the same as on mobile. In fact, on mobile and iOS simulator, the CPU usage is 120%. On desktop browser, the usage is 30%. We are totally sure that the problem is CPU usage because memory use and access are ok. Do you have any idea, why this happens? Why the same code runs great on desktop, and not on mobile browser, even in a simulator? Any help would be appreciated, cause we are lost Thank you guys!

So, I've begun fiddling with the tutorial example, but noticed that my fan was running a lot faster than it usually does. I checked the system monitor and noticed a CPU usage of around 50-60% when running the game code. This happens in both Firefox and Chrome. Is this normal? Any workarounds? It even slows down my code editor and other tasks. Sometimes it freezes for about 10 seconds, then continues but leaves the computer in a very sluggish state. - Scrolling vastly slowed down, programs shut down very slow etc. What is even more disconcerting is that nothing in the system monitor indicates any resource hog after I shut the browser down, yet the problems persist until I reboot. PS: I run Ubuntu 12.04 on a a i5 quad-core 2.5 GHz, 4 GB RAM. Bonus question: When upgrading from 1.1.3 to 1.1.5 gravity seems to get botched resolving A LOT slower than it should (and does in 1.1.3). What gives?
