Summary

Charon is a powerful data-driven game development tool designed to streamline the creation and management of static game data within your game. It allows both developers and game designers to efficiently model and edit game entities such as characters, items, missions, quests, and more, directly within the Unity/Unreal Engine/Browser environment. Charon simplifies the process of data manipulation, offering a user-friendly interface and automatic source code generation, which significantly reduces development time and minimizes manual coding errors. Charon also offers support for working with text in multiple languages, with easy loading and unloading of translated text.

With Charon, game developers can focus on creating engaging gameplay experiences without worrying about the technical details of managing game data. It is available in three deployment variants, including a standalone/offline application, web application, Unity and Unreal Engine plugins.

Why Choose Charon?

Charon replaces traditional spreadsheets or config files with an in-game database, offering a structured and efficient way to manage game data. It allows developers to focus on creating engaging gameplay experiences without worrying about the technical details of data management.

Is It Free?

The offline version, CLI and plugins are completely free and have no restrictions. They are distributed under a free license and allow you to distribute tools along with the game for modding games.

The online version, which allows working in large teams on shared game data, requires a subscription.

What is Charon

It is a .NET 8 console application that can be used as a command-line tool for performing CRUD operations with your game data, or as an HTTP Server to provide a UI for modeling and editing your game data. There are plugins for Unity and Unreal Engine that provide a more integrated experience while using Charon.
As with any .NET application, it can be launched as is on Windows, macOS and Linux and via dotnet.

How it works

Unity or the Unreal Engine plugin provides a more natural experience of interacting with game data. Check out the corresponding plugin page for more information on getting started.

To get started with standalone Charon, you’ll need the following:

• The dotnet runtime installed.
• Use standalone tool, which you can install globally using the command:

  dotnet tool install dotnet-charon --global  
  

Once set up, follow these steps:

• Create an empty gamedata.json file or use dotnet charon INIT gamedata.json command.
• Launch the Charon tool by running:

  dotnet charon gamedata.json
  

  This command starts an HTTP server and automatically opens the Charon UI in your default web browser.
• Use the intuitive web-based UI to design and edit your game data.
• After editing, utilize Charon’s source code generator to produce language/engine-specific source code for your game data.
• Integrate the generated source code into your game project. This allows you to load the gamedata.json file into your game in a structured and type-safe way, ensuring seamless and error-free data usage.

Editor's UI

<img width="894" alt="screenshot" src="https://raw.githubusercontent.com/gamedevware/charon/main/docs/assets/editor_screenshot.png"/>

C# Code Example

using System.IO;

using var fileStream = File.OpenRead("gamedata.json"); // or .gdjs
var gameData = new GameData(fileStream, new Formatters.GameDataLoadOptions { Format = Formatters.Format.Json });

var heroes = gameData.Heroes.AsList // -> IReadOnlyList<Hero>
// or
var heroById = gameData.AllHeroes.Find("Arbalest"); // -> Hero | null

C++ Code Example

#include "UGameData.h"

TSoftObjectPtr<UGameData> GameDataPtr = TEXT("/Game/Content/GameData");
auto GameData = GameDataPtr.LoadSynchronous(); // -> UGameData*

auto Heroes = GameData->Heroes; // -> TMap<FString,UHero*>
auto HeroById = GameData->Heroes.Find(TEXT("Arbalest")); // -> UHero**

TypeScript Code Example

import { GameData } from './game.data';
import { Formatters } from './formatters';

// Node.js
import { readFileSync } from 'fs';
const gameDataStream = readFileSync(gameDataFilePath);

// Blob or File
const gameDataStream = gameDataFileBlob.arrayBuffer();

// XMLHttpRequest (XHR)
// gameDataRequest.responseType -> "arraybuffer"
const gameDataStream = gameDataRequest.response;

const gameData = new GameData(gameDataStream, {
  format: Formatters.GameDataFormat.Json
});

let heroes = gameData.heroes; // -> readonly Hero[]
let hero = gameData.heroesAll.find("Arbalest"); // -> Hero | undefined

Haxe Code Example

import GameData;
import Formatters;
import haxe.io.Path;
sys.io.File;

var input = File.read("RpgGameData.gdjs"); // or .json
var options = new GameDataLoadOptions();
options.format = GameDataFormat.Json;
var gameData = new GameData(input, options);

var allHeroes = gameData.heroesAll.list // -> ReadOnlyArray<Hero>
var heroById = gameData.heroesAll.get("Arbalest"); // -> Hero
