InvFX — Inventory UI Framework (Alpha)

Warning

InvFX is currently an unstable alpha.
APIs, packages, and internals may change at any time without notice.
Do not use in production unless you are comfortable with frequent breaking changes.

🚀 What is InvFX?

InvFX is a Java inventory UI framework for Minecraft plugin developers.
It provides a modern, composable API for building custom GUIs on Paper servers — while being library-first.

• No JavaPlugin entry point.
• No heavy setup.
• Just shade the API into your own plugin and build inventories like real UI components.

---

✨ Features (alpha stage)

• API-first design — clear separation of api, spi, impl, and binding packages.
• Views — describe what should be displayed (PagedView, ConfirmView, ListView, etc.).
• Render pipeline — efficient diff-based updates, only changed slots are redrawn.
• Controllers & Events — handle clicks, drags, closes, opens, cursor changes.
• Adapters — Bukkit/Paper bindings are thin and optional, keeping the core platform-agnostic.
• Extras — pre-built components: nav bars, confirm dialogs, search inputs, animated toasts.
• Test-friendly — ships with mock adapters and schedulers so you can unit test without Bukkit.
• Shade-ready — designed to be relocated into your plugin to avoid conflicts.

🛠 Examples

Example 1 — Confirm Dialog

var mm = MiniMessage.miniMessage();

ConfirmView confirm = new ConfirmView(
    mm.deserialize("<yellow>Delete item?"),
    invfx.getItemProvider(),
    result -> {
        if (result) {
            player.sendMessage("Item deleted!");
        } else {
            player.sendMessage("Cancelled.");
        }
    }
);

invfx.open(player, confirm);

Example 2 - Simple List

ListView<String> listView = new ListView<>(
    List.of("Sword", "Bow", "Shield"),
    invfx.getItemProvider(),
    5, // content rows
    item -> MiniMessage.miniMessage().deserialize("<aqua>" + item),
    selected -> player.sendMessage("You picked: " + selected)
);

invfx.open(player, listView);
