JEngine Framework

Unity framework for runtime hot updates. Unity 2022.3+, C#.

Available Packages

JEngine.Util (com.jasonxudeveloper.jengine.util)

  • JAction: Fluent API for chainable action sequences with zero-allocation async
  • JObjectPool: Thread-safe generic object pool using lock-free CAS

JEngine.UI (com.jasonxudeveloper.jengine.ui)

  • MessageBox: Async modal dialogs with UniTask (runtime)
  • Editor Components: JButton, JTextField, JStack, JCard, JTabView, etc. (editor)
  • Design Tokens: Theme-aware colors, spacing, typography

Key Patterns

Always Use UniTask (not System.Threading.Tasks.Task)

using Cysharp.Threading.Tasks;
public async UniTask<bool> LoadAsync() { }

JAction - Always Dispose After Async

using var action = await JAction.Create()
    .Do(static () => Debug.Log("Start"))
    .Delay(1f)
    .Do(static () => Debug.Log("After 1s"))
    .ExecuteAsync();

JObjectPool - Reset State on Return

var pool = new JObjectPool<List<int>>(
    onReturn: static list => list.Clear()
);
var list = pool.Rent();
pool.Return(list);

MessageBox - Await the Result

bool ok = await MessageBox.Show("Title", "Message?", "Yes", "No");
if (ok) { /* confirmed */ }

Editor UI - Use Design Tokens

using JEngine.UI.Editor.Theming;
using JEngine.UI.Editor.Components.Button;
using JEngine.UI.Editor.Components.Layout;

var stack = new JStack(GapSize.MD)
    .Add(new JButton("Action", () => DoIt(), ButtonVariant.Primary));
