Minestom helpers

Event listeners

The typed listen extension adds an event listener and returns the same EventNode, which keeps listener setup concise and chainable:

inventory.eventNode()
    .listen { event: InventoryPreClickEvent ->
        // Handle the event with its inferred concrete type.
    }

The helper delegates directly to EventNode.addListener. It does not introduce a second event bus or change Minestom’s event propagation model.

Play packet listeners

The reified setPlayListener extension removes the class token from Kotlin packet-listener setup:

MinecraftServer.getPacketListenerManager()
    .setPlayListener<ClientPlayerLoadedPacket> { packet, player ->
        // Handle the packet with its concrete type.
    }

This delegates to PacketListenerManager.setPlayListener(Class, PacketPlayListenerConsumer). Like the Minestom method, it replaces the listener for that packet type; it does not add another listener alongside the existing one.
