Provides vector operations and conversions for Minecraft Bedrock scripting (although it should work for anything).
Copy Vector.js into your Scripts folder (bp/scripts) and put import { vec3 } from 'scripts/Vector.js'; at the top of your script
Creating and adding two vectors
let a = vec3(1,2,3);
let b = vec3(4,5,6);
b = a.add(b);
console.log(b);
Making a 10 unit long 2d vector
let a = vec2(1,2);
console.log((a.normalized).multiply(10));
Getting the normal of a triangle
let a = vec3(1,3,0);
let b = vec3(4,5,2);
let c = vec3(2,-5,6);
let normal = a.subtract(c).cross(b.subtract(c)).normalized;
