RPGCore is a toolkit for producing RPG games and mechanics in C#.

This project is currently using Unity 2018.2.3f1.

RPGCore Main Demo

At it's core, this project features a behaviour system that's used to create modular items and buffs. The behaviour system is setup using a visual scripting tool, shown below.

Graph Demo

The long-term goal of this project is to produce a toolkit for creating modular and event based mechanics for clients and servers.

Project Status

Prototype: Released
Rewrite: Work-in-progress...

"Many screenshots of RPGCore are from the "Prototype" project. I don't recommend anyone use this project commercially unless they understand it and are willing to modify it to suit their needs. This code has no multiplayer compatibility (yet) and uses a lot of lambda expressions to accomplish the node connections."

The "Rewrite" project delivers the following features:

  • A high-performance and extensible node-based behaviour system
  • Unity-independent code-base that can run on servers
  • Intuitive API for creating custom nodes

Case Studies

RPGCore is built around a modular behaviour system. One of the core uses for this system is modular items.

Fire Cape

Below is an item called the "Fire Cape". It applies the Immolate buff to it's owner, which deals damage to nearby enemies.

Fire Cape Graph

This graph in the game is interpreted by the tooltip system, which renders the "Fire Cape" tooltip as shown below.

The graph system can also be used to add additional behaviours to an item as used in Enchantments.

Enchantments Tooltip


The modular behaviour system has other applications, such as buffs and debuffs. Events can be used to trigger behaviours on ticks of the buff, and effects can be applied continuously throughout the duration of the buff.

Poisoned Debuff

The remaining duration on the buff can also be used to drive the performance of the buff (such as a slow that weakens over time).
