I'll run through you a tutorial here:
First make sure you are logged into a google account, and then head over to this page, https://www.google.com/recaptcha/admin
You will see this, and you need to fill in the information provided. For the label you may enter "Register", and for your domains...
You can use this link for reCAPTCHA, https://www.google.com/recaptcha/admin. For the Label, you may call it your hotel name, and for the domains, just put your hotel link.
Maybe look up a tutorial on how to add furniture to the catalogue, or you can use this thread: https://devbest.com/threads/how-to-add-furni-to-you-habbo-retro.78129/
The debug button is the play button, and you press it. Once that has loaded fully with no errors, you can close that, and just run your usual emulator.
using System;
using System.Linq;
using System.Text;
using System.Collections.Generic;
using Plus.HabboHotel.Rooms;
using Plus.HabboHotel.Pathfinding;
using Plus.HabboHotel.GameClients;
using Plus.Communication.Packets.Outgoing.Rooms.Chat;
namespace Plus.HabboHotel.Rooms.Chat.Commands.User.Fun...
I'm doing everything said above, but still errors that it can't find this:
The type or namespace name 'KissCommand' could not be found (are you missing a using directive or an assembly reference?)
Help?
