This is a minimal WebGL vector rendering engine written for AssemblyScript.

import { DisplayString } from '../lib/VectorEngine';

let timeChange: f32 = -2.0;

export function gameLoop(delta: i32): void {
  timeChange = <f32>delta / 1000.0;
  vectorEngineDisplay.render();

  scale = (Mathf.sin(timeChange) + 1.1) / 35.0;

  assemblyScript.scale = scale;
