ESEngine is a lightweight 2D game engine with a TypeScript SDK powered by a C++/WebAssembly backend. It comes with a visual editor for scene editing and project management, and outputs games that run in web browsers and WeChat MiniGames.

Download the editor from the releases page and install it.

1. Open the editor and click New Project
2. Enter a project name, select a location, and click Create

The editor creates a project with a default scene containing a Camera entity.

Add entities and components in the scene editor, then write systems in TypeScript:

import {
 defineComponent, defineSystem, addSystem,
 Query, Mut, Res, Time, LocalTransform
} from 'esengine';
const Speed = defineComponent('Speed', { value: 200 });
addSystem(defineSystem(
 [Res(Time), Query(Mut(LocalTransform), Speed)],
 (time, query) => {
 for (const [entity, transform, speed] of query) {
 transform.position.x += speed.value * time.delta;
 }
 }
));

Press F5 in the editor to preview.
