Minecraft-Forge Java coding: Comment connecter les commandes du serveur avec le côté client pour afficher instantanément les changements dans le monde?

Créez d'abord une commande. Voici une de mes commandes (réduite à quelques implémentations utiles que vous pouvez modifier à vos souhaits.

Vous devez l'enregistrer dans le bus d'événements approprié

/*@EventHandler
public void stop(FMLServerStoppingEvent event) {
    WhoTookMyCookies.mainThread.interrupt();
}*/
@EventHandler
public void start(FMLServerStartingEvent event) {
    startDatabase();
    WhoTookMyCookies.log.warn("Setting up commands");
    event.registerServerCommand(new InspectCommand());
}

Et la commande elle-même
