Editing this in case anyone else finds this thread looking for an answer to my question: For multiplayer games like MMORPG's, the data should be stored on the server. If it's stored on your own machine (client), then it's very easy to edit or 'hack' this data (level, money, movement speed,...).
A server made in Lacewing apparently can't handle more than 50 connections at a time, so for an MMORPG you'd have to write your own server in a real coding language like Python or C++. This also means that you can't really make an RPG and then later turn it into an MMORPG without having to do a crazy ton of editing and having done a ton of work for nothing. If you want to make an MMORPG using Clickteam Fusion, don't start by creating an RPG, create an MMORPG from the start. Furthermore, the current version of Lacewing doesn't work on newer Android devices, and Lacewing likely won't be getting any updates anymore. So if you want to make a multiplayer game for Android, you shouldn't be using Lacewing at all.
Hey, I'm just starting out with Clickteam Fusion so I still have a lot to learn, but one of the things I want to create with it is an MMORPG.
I figured creating a single player RPG would be a good way to learn more, so I could already start doing that and then later turn it into an MMORPG. However, I'm not sure if this is a good idea. Is this something that's easy to do, or would it require changing so many things that it would be better to start using Lacewing from the start?
