Code	<!DOCTYPE html> <!-- @MineKhan version Alpha 0.8.2 NOTE: The "Save" button saves your world to your local browser. Nobody else can see it. However, if you're on a public or shared computer, that save may be deleted unexpectedly. So it's a good idea to keep a safe copy of your save string somewhere where it won't be deleted. To share your save with other people, copy your world string into the "loadString" variable on line 293. Controls: * Mouse Right-click (or ctrl + left-click): place block * Mouse Left-click: Remove block * Mouse Middle-click: Pick block * Q: Sprint * W-A-S-D: Walk around * Shift: Sneak * E: Open/Close inventory * B: Toggle super (B)reaker * H: Toggle (H)yper builder * Z: Zoom * L: Toggle Spectator mode * Arrow Keys: Look around * P or Esc: Pause/unpause * 1-9: Navigate hotbar * Spacebar: Jump * Double jump: Toggle flight * Shift (flying): Fly down * Space (flying): Fly up * T: Open chat * ; (semicolon): Release the pointer without pausing (for screenshots) Notes and accreditation: * This program (MineKhan) was made by Willard (me). The original is https://www.khanacademy.org/cs/mc/5647155001376768 (just adding this so that spin-offs have it) * Phi helped impliment VAOs and entities and split the project into multiple files via GitHub. https://www.khanacademy.org/profile/ * Zushah helped me with some of the menus in the 0.6 update, and added the flower models via GitHub. https://www.khanacademy.org/profile/zushah77 * Element118 helped speed up the process of adding new textures significantly. https://www.khanacademy.org/profile/element118 * Danielkshin made an old main menu background. https://www.khanacademy.org/profile/danielkshin * This program originated as a spin-off of ScusCraft by ScusX. * It's 99% different code at this point, but I still never would have made it this far without his code for reference. * ScusCraft can be found here: https://www.khanacademy.org/computer-programming/scuscraft-3d/5145400332058624 * My original spin-off can be found here: https://www.khanacademy.org/computer-programming/high-performance-minecraft/5330738124357632 * While porting the code from PJS to a webpage, I copied the PJS source code for a few of their helper functions from here: https://raw.githubusercontent.com/Khan/processing-js/master/processing.js * The textures are 100% copied from real Minecraft, and are the property of Mojang and Microsoft with whom I have no association. * The real Minecraft game can be bought and downloaded at https://www.minecraft.net/en-us/ To-Do: * A lot. Check out the GitHub repo if you'd like to collaborate on this. * https://github.com/Willard21/MineKhan How it works: The graphics in this project are done using WebGL, which is a web implementation of OpenGL ES 2 (Open Graphics Library Embedded Systems 2). It allows us to write shader programs that run right on the GPU, which means it can run as fast as any C++ game. The infamous P3D mode in Processing.js uses WebGL behind the scenes, but it does it so inefficiently that it might as well not even being using the GPU. To properly utilize WebGL like this program does, you need to make efficient use of buffers, which are arrays containing data on all the triangles that need to be rendered. Ideally you should be rendering less than 100 buffers per frame for the slowest computers to get a good framerate. To achieve this, you can store all the textures in 1 very big texture called a "texture atlas". Then, when you're constructing the buffer, you specify which part of the texture atlas to use for each triangle you're drawing. My buffers have 8 values for each vertex: X, Y, Z, textureX, textureY, ambient occlusion, sky light, and block light. I use 1 buffer per 16x16 chunk. I use "frustum culling" to only render chunks that are visible on the screen. I learned WebGL from https://webglfundamentals.org and just by playing around with it. --> <html lang="en-us"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta name="description" content="Play creative mode Minecraft right from your browser!"> <meta name="keywords" content="Khan Academy, Programs, Search"> <meta property="og:title" content="MineKhan"/> <meta property="og:description" content="Play creative mode Minecraft right from your browser!"/> <meta property="og:image" content="https://www.khanacademy.org/computer-programming/minekhan/5647155001376768/latest.png"/> <title>MineKhan</title> <link rel="shortcut icon" type="image/ico" href="https://willard.fun/assets/minekhan.ico"> <style> .hidden { display: none !important; } .corner { position: absolute; top: 0; left: 0; } #overlay { background-size: cover; background-position: center; /* background-image: url('./background.webp'); -- Added and removed in the JS / } body { overflow: hidden; / Hide scrollbars / background-color: black; } canvas:focus { outline: none; } .world-select { width: 99vw; min-width: 300px; height: calc(100vh - 220px); position: absolute; bottom: 120px; overflow-y: auto; background-color: RGBA(0, 0, 0, 0.6); justify-content: center; margin: 0 auto; font-family: monospace; } .world { width: 250px; height: auto; border: 1px solid black; font-size: 18px; font-family: 'Courier New', Courier, monospace; color: rgb(180, 180, 180); margin: 0 auto; margin-top: 15px; padding: 5px; cursor: pointer; } strong { color: white; } .selected { border: 3px solid white; padding: 3px; } input[type=text] { background-color: black; caret-color: white; border: 2px solid gray; color: white; font-size: 24px; padding-left: 12px; font-family: monospace; } input[type=text]:focus { border: 2px solid lightgray; } #boxcentertop { z-index: 1; width: 80vw; max-width: 400px; height: 50px; position: relative; top: 30px; display: block; margin: 0 auto; } #onhover { background-color: rgba(0, 0, 0, 0.9); color: rgb(200, 200, 200); font-family: 'Courier New', Courier, monospace; word-wrap: normal; width: auto; max-width: 400px; position: absolute; z-index: 11; padding: 10px; cursor: default; user-select: none; } #quota { display: block; position: absolute; width: 99vw; margin: 0 auto; bottom: 110px; z-index: 1; background-color: RGBA(0, 0, 0, 0.6); justify-content: center; text-align: center; color: white; font-family: monospace; } #chat { position: absolute; left: 0px; top: 100px; height: calc(100vh - 200px); overflow-y: auto; overflow-x: hidden; padding-right: 20px; width: 40vw; min-width: 600px; background-color: RGBA(0, 0, 0, 0.8); color: white; font-family: monospace; } #chat > div > span { white-space: pre-wrap; margin: 0; padding: 0; } #chatbar { position: absolute; left: 30px; bottom: 0px; height: 20; width: calc(100vw - 60px); background-color: RGBA(0, 0, 0, 0.8); color: white; font-family: monospace; } .message { width: 100%; background-color: transparent; padding: 10px; word-wrap: break-word; } #background-text { position: absolute; left: 0; top: 0; width: 100vw; height: 100vh; z-index: -10; } #loading-text { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); text-align: center; color: #fff; font-size: 30px; font-family: monospace; } #inv-container { position: absolute; left: 50%; transform: translate(-50%, 0); z-index: 1; } #inv-scroll { height: calc(100vh - (min(100vh, 100vw) / 3.25)); overflow-y: auto; border-bottom: solid 2px lightgray; } #hotbar { position: absolute; left: 50%; transform: translate(-50%, 0); bottom: 10px; z-index: 0; } #webgl-canvas { z-index: -1; } </style> </head> <body> <!-- Text so that Lighthouse believes the page is loaded and to provide search terms. --> <div id="background-text"> <h1>MineKhan</h1> <p>Play MineKhan online!

The hostlist is intended to show off impressive coding ability, not gaming ability. If you've actually coded something on this and want people to see it, you'll need to remove this comment before saving it for the first time. I would encourage you to re-add the comment after saving so spin-offs of your spin-off are also hidden by default. (Personally I don't mind just seeing builds on the hostlist, but they're off-topic and I know it annoys other people.) <script> / </script> <script id="src/shaders/blockVert.glsl"
