GameObject

oxid/core exports a GameObject class:

import {GameObject} from 'oxid/core';

The class mirrors the hook shape used by the runtime:

  • onInit?(): void
  • onUpdate?(dt: number): void
  • onDraw?(): void

The default Oxid pattern is to extend GameObject and return that instance from main():

import {GameObject} from 'oxid/core';

class MyApp extends GameObject {
  onDraw() {
    // drawing code
  }
}

export function main() {
  return new MyApp();
}

Important detail​

The runtime itself only checks whether the returned app object has these hook methods. Extending GameObject is the intended and documented path, but the hook dispatch is shape-based rather than inheritance-enforced.
