This sample is available as a public repo at https://github.com/DragonGround/FortniteSample

Step-by-step Setup

• Extract this repo to {ProjectDir}/OneJS/ForniteSample
• Under {ProjectDir}/OneJS, make a index.tsx file like below:

import { render, h } from "preact"
import FortniteSample from "FortniteSample"
import { update } from "tweenjs/tween"

render(<FortniteSample />, document.body)

function animate(time) {
    requestAnimationFrame(animate)
    update(time)
}
requestAnimationFrame(animate)

• Open {ProjectDir}/OneJS with VSCode and run the tsc: watch task (Ctrl + Shift + B)
• In Unity, drag a ScriptEngine prefab onto the scene.
• Import the included CharacterManager.cs file into Unity and drag the MonoBehaviour onto a scene.
• Then include CharacterManager into the Objects list under ScriptEngine's INTEROP; name it to charman
• Make sure Live Reload's entry script is set to index.js.
• Hit Play and you should be all set

Everytime you checkout a new OneJS version (from the private repo or Asset Store), make sure you also update your ScriptLib folder. You can do so by deleting the old one, a new one will be automatically created upon running ScriptEngine. This step will be automated in the future.
