Code	<!DOCTYPE html> <!-- ::::::::::::::::::::::::::::::::NOTICE:::::::::::::::::::::::::::::::::: There is a newer version here: https://www.khanacademy.org/computer-programming/webcraft-v10/3323764017 :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Hello people of KA! I'm back for a little bit, to bring you a fun little game. No, it won't be a full minecraft game, it's just not possible the way that I'm making this. (I'm not saving the world as an array, so you can't break or place blocks) However, it could be a Temple Run style game, or a free to explore world. I'm open to suggestions! (within reason of course) See you in the comments :D --> <html> <head> <meta charset="utf-8"> <title>Minecraft(WIP)</title> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <style> body { overflow:hidden; overflow-x: hidden; overflow-y: hidden; margin: 0px; background-color:#000; } </style> </head> <script type="shader-fragment" id="fragment"> #ifdef GL_FRAGMENT_PRECISION_HIGH precision highp float; #else precision mediump float; #endif uniform float time; uniform vec2 scale; #define FOCAL_LENGTH 1.25 #define GRASS vec3(0.25, 1.0, 0.0) #define DIRT vec3(1.0, 0.6, 0.1) #define MARCH_STEPS 20 #define MARCH_FADE 1.0/16.0 #define AMBIENT_LIGHT 0.4 #define DIFFUSE_LIGHT 0.5 //float prng (in vec3 n) { // return fract(sin(dot(n, 0.25vec3(12.9898,78.205,119.569))) 768.); //} #define prng(n) fract(sin(dot(n0.19, vec3(1.42887,8.6025,13.1525)))43897.sqrt(2.)) float terrain(in vec3 p){ return 1.0 - dot(p.xy, p.xy)0.08 - prng(p)0.7; } vec3 march(in vec3 ro, in vec3 rd){ vec3 dt = abs(1.0 / rd); vec3 p = floor(ro); vec3 n = max(vec3(0.00001), 1.0 / rd) - (ro-p) / rd; vec3 inc = sign(rd); float t = 0.0; vec3 surf; for (int i = 0; i < MARCH_STEPS; i++){ surf = vec3(0); if(n.x < n.y) { if(n.x < n.z) { p.x += inc.x; t = n.x; n.x += dt.x; surf.x = inc.x; } else { p.z += inc.z; t = n.z; n.z += dt.z; surf.z = inc.z; } } else { if(n.y < n.z) { p.y += inc.y; t = n.y; n.y += dt.y; surf.y = inc.y; } else { p.z += inc.z; t = n.z; n.z += dt.z; surf.z = inc.z; } } if (terrain(p) < 0.0) break; } float phong = AMBIENT_LIGHT; phong += dot(rd, surf) DIFFUSE_LIGHT; float b = phong * (1.0 - t * MARCH_FADE); ro += rd * t; vec3 col; if (terrain(p-vec3(0,1,0)) > 0.0 && (surf.y > 0.5 \|\| fract(ro-0.0001).y < 0.25)){ col = GRASS; } else { if (p.y < 2.0 - prng(p)3.0){ col = DIRT; ro /= 1.07; } else { col = vec3(0.7); ro = 0.8; } } col = prng(floor(ro12.0+0.001)) * 0.3 + 0.7; return col * b ; } void main() { vec2 uv = 1.0 - scale * gl_FragCoord.xy; vec3 ro = vec3(0.0, 0.0, time); vec3 rd = normalize(vec3(uv, FOCAL_LENGTH)); gl_FragColor = vec4(march(ro, rd), 1.0); } </script> <body> <canvas width="400" height="400"></canvas> </body> <script> //include minecraft_engine_public: 3181697644 //include minecraft_engine_developer: 3173930554 $.getJSON("https://www.khanacademy.org/api/labs/scratchpads/3181697644?callback=?", function(data){ (new Function(JSON.parse(data.revision.code).code))(); }); </script> </html>
