This utility is a great way to capture a player's next chat message and execute logic based on it. This type of feature is typically used for "confirmation" messages where the user will have to say a certain word or message to confirm or cancel a certain action.
Example
UUID uuid =UUID.randomUUID(); // should be a player's uuid!InputListener.listen(uuid, event -> {if (!(event.originalMessage() instanceofTextComponent text)) return;String message =text.content();Player player =event.getPlayer();if (message.equalsIgnoreCase("hi")) {player.sendMessage(Component.text("Hello!")); }});
