  1. In my platformer, the player has a number of different weapons (gun, energy blast, homing missile) and there may be a number of enemies (up to maybe 6) who will have one of the same weapons. From my understanding of the weapon plugin and tutorials, I should then be making a different weapon object for each of the players weapons and for each enemy. As I am wanting to attach a particle emitter to missiles I'm then going to extend the bullet class to make a missile. Question 1: I want autofire from enemies to fireAtSprite rather than just fire, I'm assuming the best way to do this is to extend the weapon class and overwrite the fire() method to call fireAtSprite() instead? Or is there a better way? Question 2: Where do I put the collision checks for the bullets? I can see a couple of options but would really like to know the performance implications as to which would be better. 1) Put an arcade collision call in the extended bullet update method to handle hitting scenery and hitting enemies - this seems neat in some ways as the code for the bullet hitting something sits with the bullet itself, however it feels like I'm going to end up with a lot of separate collision calls. 2) Put an arcade collision call in the state update along the lines of: this.enemies.forEach(function(enemy){ this.game.physics.arcade.collide(enemy.weapon.bullets, this.collisionLayer, this.shotCollisionLayer, null, this); this.game.physics.arcade.collide(enemy.weapon.bullets, this.player, this.shotPlayer, null, this); }, this); 3) In the custom bullet constructor, add all enemy bullets to an enemyBulletsArray and collide this in the state update method this.game.physics.arcade.collide(this.enemyBulletsArray, this.collisionLayer, this.shotCollisionLayer, null, this); this.game.physics.arcade.collide(this.enemyBulletsArray, this.player, this.shotPlayer, null, this); Many thanks, Gordon
  2. long loading time

    Hello again. I continue develop a site with babylonjs, but I have a few problems. I have a scene created with blender, I generate the babylon file, the scene has some textures, I converted the textures to a ktx format, with the script in the babylon page. You can see the page in: http://entornomexicano.com/ I import the scene with: if (!BABYLON.Engine.isSupported()){ console.log("Motor no soportado"); return; } canvas = document.getElementById("renderCanvas"); engine = new BABYLON.Engine(canvas, true); // Asignamos los tipos de textura compimidos que se pueden usar var available = ['-astc.ktx', '-dxt.ktx', '-pvrtc.ktx', '-etc1.ktx', '-etc2.ktx']; var formatUsed = engine.setTextureFormatToUse(available); BABYLON.SceneLoader.Load(blendPath + "scene1/", "landScape.babylon", engine, function (newScene) { // asignamos la escena scene = newScene; // Creamos el entorno y las luces createSkybox("models/scene1/sky2.jpg"); createWaterMesh("waterMesh", imgPath + "waterbump.png", new BABYLON.Vector3(0, -0.08, 0), 6, getMeshListToRender()); createCamera(1, new BABYLON.Vector3(-0.23, 0.56,-2.73), new BABYLON.Vector3(0, 0, 0)); // arch camera createParticleSystem(); createLights(); createShadows(); createVolumetricLightEffect(); createActionsContollers(); // Wait for textures and shaders to be ready scene.executeWhenReady(function () { // Quitamos la imagen del cargador cuando termine el proceso de carga $("#loaderPadre").remove(); scene.createOrUpdateSelectionOctree(); // quitamos los calculos de los objetos para hacer mas eficiente la escena scene.meshes.forEach(function (mesh) { if(mesh.name.search("NO_") === -1) mesh.freezeWorldMatrix(); }); // Funcion para cuando se redimensiona la ventana $(window).on('resize', function() { engine.resize(); }); // Once the scene is loaded, just register a render loop to render it engine.runRenderLoop(function() { // console.log(engine.getFps()); scene.render(); }); }); }, function (progress) { if(progress.total == 0) return; $(".textoCarga").text( ((progress.loaded/progress.total)*100).toFixed(2) + "%"); }); In the callback function I return the loadign progress, but in some devices the progres is too slow, and When I already have 100% the scene still takes time to show, maybe i have doing some wrong. Somebody know, What I can do for resolve that? And other problem is the performance of the scene, I rremoved some elements and I have down the quality of the shadows, but the fps is 30, How I can increase the speed? the complete code is in: https://github.com/flelix/entorno-models.git in the folder: entorno-models/code/proyBabylon/entorno/ here you can see the project. I hope you can help me. Thanks and regards.
  3. webgl debug by firefox

    Hi all, currently I'm read master RICH's tutorial for improve performance by batch texture. when I use the firefox dev tools canvas capture in the article https://phaser.io/tutorials/advanced-rendering-tutorial/part5 it works when I use canvas renderer, but when I change to webgl, it can not capture the analysis. FF shows error and break the app. TypeError: methodSignatureEnums is not a function-----------------call-watcher.js:168:34 I tried many version of FF and phaser. none of them can work. is there anyone tried this before and works. please give me a workable FF version, many thanks
  4. Hi, I'm a total noob at Babylonjs, but I'm playing around with remaking a previous raw Threejs project in Babylonjs. It's a physics based stacking game, and is really very simple (nothing but boxes), but I still seem to get really bad framerates. The thing is, when I made this in Threejs I had no such problems. I’m using 3.1.0-beta3 (which seems to be the default through NPM). I’ve tried switching to the previous release but that gives me the error TypeError: Cannot assign to read only property 'RGBA16F' of object '#<WebGL2RenderingContext>'. I’ve also played around with anti-aliasing and adaptToDeviceRatio on/off but that seems to make little difference. Also SceneOptimizerOptions causes a bug in CSG for me, where it errors out on finding position of null of my mesh. My project consists of 2 files, scene.js and app.js (sorry about the formatting, why isn't here a code tag) // app.js import { Vector3, Animation, MeshBuilder, CSG, PhysicsImpostor, StandardMaterial, Color3 } from "babylonjs" import { scene } from "./scene" const stack = [] function makeGround() { var ground = MeshBuilder.CreateBox('ground1', { height: 40, depth: 35, width: 35, subdivisions: 1 }, scene) ground.position.y = -22.5 ground.physicsImpostor = new PhysicsImpostor(ground, PhysicsImpostor.BoxImpostor, { mass: 0 }) stack.push(ground) } function makeBox() { let top = stack[stack.length - 1] var boundingBx = top.getBoundingInfo() let boundingBox = boundingBx.boundingBox var box = MeshBuilder.CreateBox('box1', { height: 5, depth: boundingBox.extendSize.z * 2, width: boundingBox.extendSize.x * 2, subdivisions: 1 }, scene) box.position = boundingBx.boundingBox.centerWorld.clone() box.position.y = (stack.length - 1) * 5 box.material = new StandardMaterial("xx", scene) box.material.diffuseColor = new Color3(Math.random(), Math.random(), Math.random()) box.physicsImpostor = new PhysicsImpostor(box, PhysicsImpostor.BoxImpostor, { mass: 0 }) stack.push(box) animateBox(box) } function makeFirstBox() { var box = MeshBuilder.CreateBox('box1', { height: 5, depth: 35, width: 35, subdivisions: 1 }, scene) box.position.y = 0 box.physicsImpostor = new PhysicsImpostor(box, PhysicsImpostor.BoxImpostor, { mass: 0 }) stack.push(box) animateBox(box) } function animateBox(box) { let lefty = (stack.length - 1) % 2 == 0 let prop = lefty ?

  5. I noticed that in my game the Pixi Application takes lot of CPU resources when it's running. Even when it's in background or is not visible, it consumes the CPU. Two Chrome processes are constantly using 25-30% CPU on my linux box (more on my macOS). It became very troublesome while working from a cafe on my macbook pro without charger. The app drained by battery in no time. Only way to avoid this is to stop the pixi application ticker when you don't want it to consume resources. For a typical Pixi.js application, i.e. a game, it does make sense for the game to pause when it goes in background. Therefore I wrote this small routine using the `blur` event handler, to pause the Pixi app, whenever the window looses focus. This drops the CPU usage to 6-7% by Chrome processes. In a browser or electron app, the window.onblur callback will get called whenever the focus switches from the app window to some other application (or even dev console). However in jsfiddle environment, you need to click on the application first and then click somewhere else for testing this functionality. That's because the code runs inside an iframe on jsfiddle page. The simple resume dialog lets you resume the app when you want. You can try it here: https://jsfiddle.net/jay3sh/ft8am5fr/13/ If you have any other tips, or suggestions to reduce CPU usage, I would love to know.
  6. Hi all, Another silly question. Does mesh (simple mesh) size affect performance? Regards
  7. Hi everybody. Here I come again with a new question for this incredible community. By the way, I think it will be "super easy" for someone which a good knowledge of the BJS internals. The case is that, following with my current development (tap simulator) I'm now focused on the performance. My doubts are mainly about the proper use of the method "clone" of the "Texture" object. Doubt 1) Suppose you have a Standard Material, you create it following the usual way, something like this: matFoo=new BABYLON.StandardMaterial("Foo_Material",myScene); matFoo.diffuseColor=new BABYLON.Color3(0,0,0); matFoo.opacityTexture=textFoo; matFoo.emissiveTexture=textFoo; Note that we are using the texture (textFoo) on two channels, opacity and emissive. Is this effective in terms of resource economy or I must follow this other approach?: matFoo=new BABYLON.StandardMaterial("Foo_Material",myScene); matFoo.diffuseColor=new BABYLON.Color3(0,0,0); matFoo.opacityTexture=textFoo.clone; matFoo.emissiveTexture=textFoo.clone; Doubt 2) Now we have a similar scenario, when we must assign a previously created texture, but this time we want to assign it to a series of Particles: ... textSprite=new BABYLON.Texture("assets/textures/flarealpha.png",myScene); ... myParticles=new BABYLON.ParticleSystem("Particles",10000,myScene); myParticles.emitter=new BABYLON.Vector3(0,0,0); myParticles.particleTexture=textSprite; ... This time, as we have a lot of particles chances are that it is better to use textSprite.clone() in order to assign the sprite image to each particle, at last line of shown code. Isn´t it? Doubt 3) Last but not least. When you (as me) arrives at the conclusion that PBR materials are the way-to-go (in order to achieve a decent look with your CGs), you are going to use, among others, the environment channel (dds files in current 3.0 version of BJS). Here I have certainly a doubt and a thought. Going first with the last, I think the environment should not be a PBR Material property (as currently is), but a scene one, as certainly is very weird to think in a scene with more than one environment (?). Anyway, as at the moment this is not the case, and we have to assign the same value of "environment" for each PBR Material, we find ourselves setting time after time the same texture (dds file) in this way (please focus only on the reflectionTexture property): ... matTube=new BABYLON.PBRMaterial("MaterialPBR_Tube",myScene); matTube.albedoTexture=new BABYLON.Texture("assets/models/Tubo_BaseColor.png",myScene); matTube.metallicTexture=new BABYLON.Texture("assets/models/Tubo_Metalico_PBR.png",myScene); matTube.bumpTexture=new BABYLON.Texture("assets/models/Tubo_Normal.png",myScene); matTube.reflectionTexture=textEnvironment; matTube.microSurface=0.96; matTube.useRoughnessFromMetallicTextureAlpha=false; matTube.useRoughnessFromMetallicTextureGreen=true; // matTap=new BABYLON.PBRMaterial("MaterialPBR_Tap",_Scene); matTap.albedoTexture=new BABYLON.Texture("assets/models/mono/Manetas_BaseColor.png",myScene); matTap.metallicTexture=new BABYLON.Texture("assets/models/mono/Manetas_Metallic_PBR.png",myScene); matTap.bumpTexture=new BABYLON.Texture("assets/models/mono/Manetas_Normal.png",myScene); matTap.reflectionTexture=textEnvironment; matTap.microSurface=0.96; matTap.useRoughnessFromMetallicTextureAlpha=false; matTap.useRoughnessFromMetallicTextureGreen=true; // matSprinkler=new BABYLON.PBRMaterial("MaterialPBR_Sprinkler",myScene); matSprinkler.albedoTexture=new BABYLON.Texture("assets/model/mono/Resto_BaseColor.png",myScene); matSprinkler.metallicTexture=new BABYLON.Texture("assets/models/mono/Resto_Metallic_PBR.png",myScene); matSprinkler.bumpTexture=new BABYLON.Texture("assets/models/mono/Resto_Normal.png",myScene); matSprinkler.reflectionTexture=textEnvironment; matSprinkler.microSurface=0.96; matSprinkler.useRoughnessFromMetallicTextureAlpha=false; matSprinkler.useRoughnessFromMetallicTextureGreen=true; ... Here, as in the case of my first doubt, I'm thinking, obviously in using "matXXX.reflectionTexture=textEnvironment.clone();", but I don´t know if that is a way to enhance performance, and by the way if dds files are buffered in a way they can benefit of texture cloning mechanism. Ok, this is all, sorry for the length of the question and, as always, thanks in advance for your time! Regards.
  8. Raycast Performance

    Hey guys... got a couple of quick questions about raycasting... 1... Is recasting an 'Expensive Thing' for BabylonJS. I ask because in unity, a fully scripted player character might by casting 6 - 10 rays on each frame... One ray might be be checking ground distance... Four separate rays might be casting to the four near clip plane points of the camera to check for Collision and or occlusion and one ray might checking wall distance ... and so on... Now that apparently is FINE in Unity on a native platform... Would that many rays be TOO MUCH for a BabylonJS Game... ??? 2... Is is possible to create a "Sphere Cast" type functionality like Unity Has... Example: Physics.SphereCast public static bool SphereCast(Vector3 origin, float radius, Vector3 direction, out RaycastHit hitInfo, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal); Parameters origin The center of the sphere at the start of the sweep. radius The radius of the sphere. direction The direction into which to sweep the sphere. hitInfo If true is returned, hitInfo will contain more information about where the collider was hit. (See Also: RaycastHit). maxDistance The max length of the cast. layerMask A Layer mask that is used to selectively ignore colliders when casting a capsule. queryTriggerInteraction Specifies whether this query should hit Triggers. Returns bool True when the sphere sweep intersects any collider, otherwise false. Description Casts a sphere along a ray and returns detailed information on what was hit. This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size, such as a character, will be able to move somewhere without colliding with anything on the way. Think of the sphere cast like a thick raycast. In this case the ray is specified by a start vector and a direction. Notes: SphereCast will not detect colliders for which the sphere overlaps the collider. Passing a zero radius results in undefined output and doesn't always behave the same as Physics.Raycast. See Also: Physics.SphereCastAll, Physics.CapsuleCast, Physics.Raycast, Rigidbody.SweepTest. using UnityEngine; using System.Collections; public class ExampleClass : MonoBehaviour { CharacterController charCtrl; void Start() { charCtrl = GetComponent<CharacterController>(); } void Update() { RaycastHit hit; Vector3 p1 = transform.position + charCtrl.center; float distanceToObstacle = 0; // Cast a sphere wrapping character controller 10 meters forward // to see if it is about to hit anything. if (Physics.SphereCast(p1, charCtrl.height / 2, transform.forward, out hit, 10)) { distanceToObstacle = hit.distance; } } } Yo @Deltakosh ... Gotta ping you in here ???
  9. Stuck at 33 FPS on iOS 11

    Ever since I updated to iOS 11, I’ve noticed phaser games now seem to be stuck on 33fps on my iPhone 7. I wondered if it was just the games I made then I tested the bunny mark link below and it was the same. Has anyone experienced this? http://phaser.io/sandbox/Pjdxyqzl/play
  10. Hi, I'm currently preloading in a single sprite atlas (png image with a json data file) for one sprite (by this i mean a character i want to animate). However, the problem is that the sprite atlas image file is pretty big (over 8000x6000 sometimes) and there's FPS drops on lower end machines/older browsers. I'm not 100% sure that the FPS drops are caused by the large image file, but when i reduced the sprite atlas image file's size, it fixed the issue. My question is, is there a good way I can assign multiple sprite atlases to one character/sprite? Also, would that even help the issue? I want to keep decently high resolution frames so in the end this solution doesn't actually reduce the total size of images being preloaded, just preloads multiple smaller images instead of one huge one. I want to do something like: game.load.atlas('mysprite', 'assets/sprites1.png', 'assets/sprites1.json'); game.load.atlas('mysprite', 'assets/sprites2.png', 'assets/sprites2.json'); this.sprite = game.add.sprite(game.world.centerX, 300, 'mysprite'); // 'walking' is part of the sprites1.png this.sprite.animations.add('walking', Phaser.Animation.generateFrameNames('walking', 1, 6), 5, true); // 'flying' is part of the sprites2.png this.sprite.animations.add('flying', Phaser.Animation.generateFrameNames('flying', 1, 6), 5, true);
  11. get data from Texture

    Hey, i'm trying to get the data source from a loaded Texture in BABYLON. But I haven't found a way to do this. Basicly my idea is to get the data from the image and save it as base64 in the local cache. And then I can get the image from the cache again and load it into BABYLON. This should improve performance and result in faster loading times once you already loaded the scene once. Does this accually makes sense or is there a better way of caching textures?
  12. Choppy tweens on mobile (Cordova)

    Hi all, I have a game which I've turned in to a cordova app. Gamephysics with collision are working smooth, but when I am using tweens it sometimes lags a little bit. I am using Crosswalk and are testing on a Sony Xperia Z3. I've tried removing all backgrounds and animation and left only one sprite doing the tweens, but the lags remain. Everything is smooth on the desktop browser. Anybody got any tips on improving the performance?
  13. Work offer

    Hi guys, After some previous attempts to solve some problems in our project, we saw that we were not getting anywhere so we decided that we needed a professional help. This is the offer we published on the Upwork platform, so if anyone is seriously interested in completing the job, please contact us. This is the text of the offer: _______________________________________________________________________________________________________________________________ Representation of a snow-covered mountain scene in Babylon.js Engine The task consists of representing a snow-covered mountain landscape with forest and water bodies in Babylon.js. The focus has to be made on the visual attractiveness while still offering high performance. An example of a scene like that would be this one (Scene1), made in Three.js. We are providing a basic scene (Scene2) made in Babylon.js, and the following improvements have to be made to this scene: 1) Implementing a GLSL Shader / Babylon.js Custom Material which accepts the following criteria: Terrain Texture: - Rocks: should be a procedural texture with a nice natural transition between the snow and the rock texture like in the Scene1. - Water: should be the WaterMaterial provided by Babylon.js Material library. - Snow: it is already acceptable in the Scene2, but any visual improvement is welcome. If needed, the mask image for the texture mapping can be also provided as three separated alpha mask images, one for each type of texture. Furthermore, it has to support a Dynamic Texture on top of the Terrain Texture, so that it should be possible to draw directly on the ground. An example of this would be this scene (Scene3), implemented with ShaderBuilder : The problem with this scene is that it lacks bump maps, fog and shadow effects. There should be visual consistency across the most popular browsers: Chrome, Firefox, Edge and Safari. _______________________________________________________________________________________________________________________________ If you have any questions, we're ready to answer them. Thanks!
  14. Hello! I'm building a soccer keepie uppies game. I have many texture atlas' that make up the player and ball for my animations and some static images placed in the scene. There is also a score text in the top left corner. This all runs fine on desktop but on my iPhone 6s the fps is around the high 40's. If I remove the BitmapText then it's back up to 60fps. Even removing the player and ball and pretty much having only the score text in the scene I am noticing a hit in performance. Even if I don't update the score and have it just static at 0 points. I'm really wracking my head with this. I've been looking for a solution for nearly a week now and can't seem to come up with anything. I fell like I've tried all the tricks : ( Unfortunately I can't show any code as I am not permitted to. Has anybody else ran into an issue like this? Really hope somebody can help as I'm at a loss... Thanks!
  15. memory leak?

    During a recent profiling we found that a Scene object is being retained in the heap infinitely even if dispose is called. Apparently the Engine keeps an array of compiledEffects which then has fallback meshes that keep a reference to the scene and that prevented the scene object from being garbage collected. Is this expected? There's about 9MB of stuff that can be wiped out from our pathetic mobile device memory, so definitely hoping there's a way to collect it.
  16. Hi peeps, I've already published a similar topic not a while ago, but we couldn't really reach any conclusion: http://www.html5gamedevs.com/topic/32079-sprite-occlusion-for-performance/ I have this demo: http://devel.arinnova.com/tests/3dmaps/babylon_demo/ I'm trying to get a similar forest to this three.js scene: https://www.piste.io/#!/cortina . Notice how the forest is really dense and the FPS are really good. What I've already tried without success: 1) Loading meshes instead of sprites and applying LOD mechanism resulted in very low FPS. 2) Using mesh instances instead of sprites, still very low FPS 2) Temechon kindly helped me and coded a LOD function for sprites, but unfortunately it was more or less the same FPS as without the LOD. 4) Showing all the 54k trees, but using a particle system instead of sprites, which helped to reduce the draw calls, but the FPS were still low. 5) I've implemented a "poor man's LOD". I separated the 54k trees into 9 chunks, each chunk corresponding to a specific area. Then at every frame I calculated the distance from the camera to the central point of each area. If it was close enough to the camera, I showed the area trees and if not, I removed them. This way at each frame I had to calculate distances to only 9 points instead of 54k points, which helped but visually it was not pretty at all. Even applying a brown texture on the terrain underneath the trees, the chunks of trees appearing and disappearing all at once are very noticeable. 6) I also reduced the tree image size to 128x128, just in case, but I'm not sure it had an effect on FPS. Using an image of a pine tree or a leafy tree would create much more perception of a dense forest, but unfortunately I can't use those. The scene is a winter map of a specific real-world area with leafless trees and I'm trying to be as realistic as possible. A silly idea I've also tried was using an image of a group of trees instead of an image of a single tree. It obviously looked fake, especially when rotating the camera. Some other ideas that I've had but have not tried: Solid Particle System -> as it has more effect on performance than a simple particle system and I've already tried that. Octrees -> could this help me? I've read the tutorial but I'm not sure I understand how could I apply it to sprites. I don't know how camera.maxZ works internally, but is there possibly any way to apply it only to sprites, so the nearest sprites only are visible? Could I implement my own camera that does this? tldr; I'd like to show ~200.000 trees in my scene with minimal performance drawback. Thanks a lot in advance!
  17. I'm looking for ways to optimize a scene I created in the Playground. This scene is based on previous work from another thread, I just added some objects and logic to mimic a small game. It uses native CannonJS for the PFS-camera and movement of the monster models. I used the code and model from the instances demo. From line 16, you can turn on and off physics for the monsters, skeletal animations, the skybox, trees, shadows, procedural textures(grass), and whether or not the monsters should lookAt and follow the player. As well as specify the amount of trees + the range and amount of monsters. https://www.babylonjs-playground.com/#FZZV7K#23 I'm only hitting around ~30 FPS with this example. Is a scene such as this too heavy for WebGL and browsers? The trees are instances, so unless I clone and merge them, I don't see what could be changed there. Maybe a smaller, compressed texture. The monster models all have skeletons and animations, so no instances or merging can be used here. Disabling physics seems to give some FPS boost, so maybe using a worker would do some good in this example. I'll give this a try, and see what effect it has on overall performance. Here's a minimized version, with most things stripped, and 50 monsters without animations. https://www.babylonjs-playground.com/#FZZV7K#24
  18. Hi everyone, We've been working on a 3d mobile RPG game for a few weeks using Babylon.js and what we've been continuously struggling with is how challenging it is to keep 60fps on mobile. Let me share the "game" here to show you what the scene looks like: https://xiaobaker.github.io/. Don't laugh. Some stats: We have a ground mesh with standard material We have 4 different kinds of environment objects, tree1, tree2, rock1, rock2. We created 50 meshes of them using mesh.createInstance(). We have up to around 10 active characters in the camera. Each character has 6 meshes. I don't think we can instance them because each of them will need its own bone animation (one day -_-). Under 50 draw calls in total Running this on iphone 6 with ios 10.3.3 gives under 40 fps. We are hoping to keep it at 60 with even more stuff we want to add later on. I'm not super experienced with graphics optimizations, so could really use some advice here. A few optimizations I'm thinking of: The environment objects never change position or anything. How can we optimize for that? They use different materials, so I can't just merge them. Also, freezeWorldMatrix() on instanced meshes seem to destroy the mesh. Currently in the inspector it shows that mesh selection is taking 9.4ms and render takes 13ms. How do we bring mesh selection down? Octree can bring mesh selection down to 4.5ms but still that's quite a bit. How do we debug what's happening in the 13ms of "render"? How do we debug webGL performance issues on mobile devices in general? Any general suggestions on how to optimize for a game like this? Any inputs are greatly appreciated!
  19. low fps on iphone 6plus

    pixi.js is doing amazingly well for us on all our android and ios devices except iphone 6 plus. First discovered in our own game, later on we found that it can be successfully reproduced using http://www.goodboydigital.com/pixijs/bunnymark/. On most devices, it can keep 60 fps at even 50k bunnies, which is impressive. However, iphone 6 plus seems to be an exception. FPS drops to around 30 with just 3k bunnies, and close to zero with 10k. Anyone has any clue on what's special with iphone 6 plus?
  20. Hello everyone, Is is possible to implement some occlusion or LOD-like mechanism for sprites in Babylon? I have a scene with a very large terrain and some forest areas represented by thousands of tree sprites. There are so many sprites that they actually affect performance. Could someone point me in the right direction? Is there a way to adapt LOD for sprites? Or could I put the camera into some kind of transparent mesh and in some way occlude the sprites behind the mesh walls?
  21. Hi, I have a scene with around ~800 non-static meshes moving around, and I find the main performance bottleneck is the time taken by Babylon calling evaluateActiveMeshes, which in turn calls computeWorldMatrix and _updateBoundingInfo on most of the meshes. However, the nature of my scene is that most of the meshes never rotate, and I separately track their locations and bounding info. So in principle, it seems like I could tell Babylon they're static (by calling freezeWorldMatrix?), and then manually update their boundingInfo objects, and set their worldMatrices to simple translation matrices. Would this be a safe approach, or has anyone tried it? Or is there some built-in way of achieving a similar result? Or does freezing the world matrix have other implications that would cause this to break? Thanks!
  22. Hi everyone, We made a simple runner demo with Phaser that works as a base for all our future projects. We are using node modules to make our development easier. We shared it on github so more people can use it and learn from it: https://github.com/Tembac/ChimangoGamesDemo You can try it here: http://chimangogames.com/games/demoRunner/index.html It works great on every device we tested but some people reported that it is running slow on Ipad mini 1gen. We don't have that platform to test so it is hard for us to know how to improve it. Can someone give us tips on how we can improve performance for this demo on that platform? Thanks!
  23. Hello, I want to create an action-adventure platform game (similar to Swordigo). I chose Phaser because I've been using JavaScript for 5 years and I feel prepared regarding the patterns to use. I'm new to game development and I have a question: Phaser is suitable for this kind of game? Or can it cause performance problems on mobile phones? The game will have to work on iOS and Android in a WebView widget.
  24. Hey, I made a post before about scaling for high DPI monitors and thought that I came up with an acceptable solution but here I am again with some of my concerns about scaling and performance on 4k/retina displays. Even when I start from scratch and just draw a circle the performance is garbage. The weirdest thing is that the performance drops as soon as I put 1 pixel of the Chrome window on a 4k screen. So basically I have 2 screens connected and I move the Chrome window off the normal screen towards the 4k screen and immediately the frame rate drops to 30 instead of 60. I've logged the canvas and rendered size and there is no change when I put it partially on the other screen so the same stuff gets rendered. I've done the same to some other games and didn't notice this performance drop at all. It also happens with the examples and the bunny benchmark as shown in the crappy video below So my question is why the performance is suddenly so bad when I move the window over towards the 4k monitor. I would really appreciate if people have any tips on how to make sure the game looks good and performs well on 4k/retina displays. CSS scaling makes the performance better but then everything becomes extremely blurry and it's really not acceptable. Is it even possible to make web games that look great for 4k/retina displays with PIXI or in general?
  25. Phaser.Graphics anchor / pivot

    g'day g'day I've been lurking around a few forum posts addressing anchoring with Phaser Graphics objects and why you can't do it. I gathered it was something to do with it being a lower level issue with Pixi (don't quote me on that) the solution for dealing with this seemed to come down to either using pivot or generateTexture() and loading into image / sprite. Since it looks like post 2.5.0 we've lost Phaser.Graphics.pivot, I was wondering if there was any performance loss / gain by calling generateTexture() and loading into a Phaser.Image / Phaser.Sprite and anchoring from there? I guess simply put, is it cheaper to have 10 Phaser.Graphics or 10 Phaser.Images? ( bonus points for shedding light on what happened to pivot )
