[OpenRPG] : Free Unreal Engine 4 RPG Systems!

Edit 25/2/2021: I have created a Discord channel https://discord.gg/SkYcWZrEEM for everyone who wants to talk about the project, ask questions, etc.

Edit 06/2/2021: Well, it has been a long time since I posted this. I really didnt expected to reach 116 stars on GitHub at the moment I am writing this in the inventory system, because apart from this post I have not given it any extra advertising.

For all you to know, after that system I created other 3 systems that I am going to put here for everyone that may want to use them. I am going to rewrite the post to structure it better so you can see a little description for each system with its main features and extra links for documentation I tried to make.

I have been talking to the UE4 Marketplace Team to try to upload this assets for free, as I think it is the best place for this because people does not see the forum as often as the marketplace. The thing is that I dont know if I will be able to maintain this assets because my life has changed a lot since I first uploaded the inventory system here (in fact I was still at university). Anyway, they all have a really great quality, I put a lot of effort in doing this the best I was able to. For now, I have reworked the post to show all the systems, and I will keep talking to the marketplace team to see what we can do.

OpenRPG: Stats

This powerful, modular, flexible and efficient stats system will allow you to create not only stats with buffs and effects, but also attributes and custom leveling system, very common in most RPG games. You will be able to extend any actor functionality in your game with the features of this system easily and getting it implemented very quickly!

It has been structured to be easy to understand and follow, so everyone is capable of understanding how the whole system works, and with this documentation every aspect of it will be carefully explained. Even though im a completely beginner on documenting, i have tried to structure it from a general overview of the folder structure and its content to a deeper look at each part of the whole system. On each part i will show you some comprehensive guides that will clarify how to expand the system to adapt every aspect of it to your needs, as well as a look at the most important blueprints that handles the overall system functionality, which are the actor components. Then you will learn how to migrate and integrate the system into your own project.

Features

Stats

  • You can also configure if you want to track the current value of any stat. This is useful in some stats like health, when you have the current and the maximum health.

Attributes

  • Create your own attributes like intelligence, strenght, vitality, etc. As said with stats, you can also create your own sets of attributes.
  • Managed via datatable.
  • Add your custom bonuses to stats when any of the attributes values are modified!
