海外TECH	DEV Community	Motion-controlled Fruit Ninja game using Three.js & Tensorflow.js	https://dev.to/devdevcharlie/motion-controlled-fruit-ninja-game-using-three-js-tensorflow-js-18de	Motion controlled Fruit Ninja game using Three js amp Tensorflow jsOver the past few weeks I ve spent some time building a clone of the Fruit Ninja game you can play with hand movements using web technologies Demo Feel free to check the live demoIn this post I m gonna go through the steps I took to build it the tools I used and the different challenges I encountered If you re more into videos I made a quick video tutorial Step Breaking the problem downThe first thing I always do when I come up with an idea is spend some time figuring out how to break it into smaller pieces This way it allows me to identify parts of the project I might already know how to build where I need to do some extra research identify the different tools I need to use based on the features and finally have a rough idea of the timeframe needed to build it For this particular project I ended up with the following parts Get the pose detection working Set up the D scene Add D objects Map the D hands movements to the D world Creating the hand trail animation Add collision detection between the hands and D objects Add the game logic points sounds game over etc Refactor Deploy Step Picking the toolsNow that the project is broken down into independent chunks we can start thinking about the tools we need to build it Pose detectionI knew I wanted to be able to detect hands and their position Having worked with the PoseNet library before not only did I know that it was a good tool to do this but I also knew it wouldn t take me too long to implement it again D sceneI also knew I wanted to use D in the browser One of the best libraries for this is the amazing Three js Having used it before as well I decided to go with it instead of trying something like Babylon js or p js only because my free time is limited and I want to optimise how I use it D objectsThe goal of the game is to slice some fruits and avoid bombs so I needed to load these D objects in the game Even though I could have gone ahead and designed them myself in softwares like Blender this would have taken a lot longer Instead I used Poly to search through assets created by other people and available to download Hand trailsI wanted to visualise where my hand was in the D scene I could have done it by showing a simple cube but I wanted to try something a little different I had never tried to create some kind of trail effect so I did some research and found a really cool little library called TrailRendererJS that lets you create a nice looking trail effect SoundsI also wanted to add some sounds to the game Even though I could have done this using the native Web Audio API I sometimes find it a bit difficult to use There s a few JavaScript libraries that offer a level of abstraction but my favourite is Howler js HostingI decided to host this experiment on Netlify not because I work there but because I find it the simplest and fastest way to deploy stuff at the moment Step Building the thingWithout going through the whole code here are some samples of the main features Pose detectionTo use PoseNet you need to start by adding the following scripts to your HTML if you re not using it as an npm package lt script src tensorflow tfjs gt lt script gt lt script src tensorflow models posenet gt lt script gt Once you have access to the library you need to load the model const loadPoseNet async gt net await posenet load architecture MobileNetV outputStride inputResolution multiplier video await loadVideo detectPoseInRealTime video Here we start by loading the machine learning model then we initialise the video feed and once both of these steps have completed we call the function responsible for detecting the body position in the webcam feed The loadVideo function initiates the webcam feed using the built in getUserMedia function const loadVideo async gt const video await setupCamera video play return video const setupCamera async gt if navigator mediaDevices navigator mediaDevices getUserMedia throw new

minPoseConfidence const leftWrist keypoints find k gt k part leftWrist const rightWrist keypoints find k gt k part rightWrist console log leftWrist position will return an object with shape x y requestAnimationFrame poseDetectionFrame poseDetectionFrame Setting up a D sceneTo start using Three js you need to load it lt script src gt lt script gt Then you can start creating your scene camera and renderer const initScene gt scene new THREE Scene camera new THREE PerspectiveCamera window innerWidth window innerHeight camera position set scene add camera const initRenderer gt renderer new THREE WebGLRenderer alpha true renderer setPixelRatio window devicePixelRatio renderer setSize window innerWidth window innerHeight let rendererContainer document getElementsByClassName game rendererContainer appendChild renderer domElement Loading D objectsTo load D models you need to add some additional loaders the OBJLoader and MTLLoader These two loaders will allow you to load the D objects and their material const fruitsModels model banana Banana material banana Banana name banana model apple Apple material apple Apple name apple model bomb bomb material bomb bomb name bomb const loadFruitsModels gt return fruitsModels map fruit gt var mtlLoader new THREE MTLLoader mtlLoader setPath assets mtlLoader load fruit material mtl function materials materials preload var objLoader new THREE OBJLoader objLoader setMaterials materials objLoader setPath assets objLoader load fruit model obj function object object traverse function child if child instanceof THREE Mesh var mesh new THREE Mesh child geometry child material fruitModel mesh fruitModel name fruit name fruits push fruitModel generateFruits return fruits In the code sample above I am separating the step that loads the models to the one that appends them onto the scene I am doing this as I want to load the models only once but be able to generate new objects as they appear disappear from the screen const generateFruits numFruits gt for var i i lt numFruits i const randomFruit fruits generateRandomPosition let newFruit randomFruit clone switch newFruit name case apple newFruit position set break case banana newFruit position set break case bomb newFruit position set newFruit scale set break default break fruitsObjects push newFruit scene add newFruit renderer render scene camera To make the code sample above easier to read I m setting the position at x y however in the real game they are set randomly as the fruit is created and appended to the scene Mapping D coordinates to D positionThis part is one of the trickiest and to be honest one that I don t think I can explain properly The complexity lies in the fact that the D coordinates from PoseNet don t map directly to coordinates in the Three js scene The coordinates PoseNet gives us are the same you would get if you were logging the position of the mouse in the browser window so the value on the x axis would go from to over for the width in pixels However coordinates in a D scene don t work the same way so you have to convert them To do this we start by creating a vector from our hand coordinates const handVector new THREE Vector the x coordinates seem to be flipped so i m subtracting them from window innerWidthhandVector x window innerWidth hand coordinates x window innerWidth handVector y hand coordinates y window innerHeight handVector z Then we use the following bit of magic to map the coordinates to a D world and apply them to our hand mesh handVector unproject camera const cameraPosition camera position const dir handVector sub cameraPosition normalize const distance cameraPosition z dir z const newPos cameraPosition clone add dir multiplyScalar distance hand mesh position copy newPos Collision detectionThis part is the other tricky one Only after the D coordinates have been mapped to D ones can we work on collision detection From what I know you cannot work on this collision detection directly from D coordinates to D objects The way we re doing this is by implementing what is called Raycasting Raycasting is the creation of a ray casted from an origin vector our hand mesh in a certain direction Using this ray we can check if any object in our scene intersects it collision The code to do this looks like this const handGeometry hand mesh geometry const originPoint hand mesh position clone for var vertexIndex vertexIndex lt handGeometry vertices length vertexIndex const localVertex handGeometry vertices vertexIndex clone const globalVertex localVertex applyMatrix hand mesh matrix const directionVector globalVertex sub hand mesh position const ray new THREE Raycaster originPoint directionVector clone normalize const collisionResults ray intersectObjects fruitsObjects if collisionResults length gt if collisionResults distance lt This distance value is a little bit arbitrary console log Collision with a fruit If you don t understand entirely what it does it s ok I find it pretty complicated The main parts you need to understand is that we clone the position of our hand originPoint we loop through all the vertices in the hand mesh we create a Raycaster entity and check if the ray intersects with any fruit object If it does there s a collision Hand trailsTo render the hand trail the code is a bit long but if you want to have a look I d advise you to check the example from TrailRendererJS directly I just made some changes to fit the style that I wanted and removed the bits I didn t need Playing soundsTo start using Howler js you need to add the following script tag in your HTML lt script src gt lt script gt Once it s loaded you can use it like this let newFruitSound new Howl src assets fruit ma newFruitSound play ChallengesHere are a couple of challenges I encountered while working on this project Positions in DI find positioning objects in D quite tricky especially when I am using OBJ models downloaded from somewhere else When I loaded the apple model in my scene I assumed that when setting the x y z coordinates I could use the same for the banana and bomb model but it turned out not to be the case Depending on how the objects were created in a D software they might have a different scale or position in their own bounding box As a result I had to manually test different positions and scale for each model loaded which can take a while This issue also impacted the collision detection Sometimes raycasting didn t seem to work if I modified the scale of the object I then played with the z axis to bring objects closer or further from the camera but as a result the collision detection doesn t work of the time because of the check collisionResults distance lt Without this check for distance though collision seems to be detected even when I don t hit a fruit on the screen so there s obviously something I don t quite understand there PerformanceWhen working on this type of side projects I know that the performance is not gonna be the best because of how much I m expecting the browser to handle However considering I am doing live pose detection D animation and collision detection in the browser I don t think the current lag is THAT bad We can always improve performance though so I tried to do that by running a Lighthouse audit fixed a few things and ended up with a pretty good score However this is where web performance can mean different things Technically performance metrics like first paint time to interactive etc were pretty good but it didn t mean that the game experience felt performant I don t know yet if there is really anything I could do about that but I think it would be an interesting area to dive into Extra resourcesRepoOther side projects using similar tech Beat Pose Beat
