Summary

Charon is a powerful game development tool that streamlines the game development process. It provides a structured approach to designing and modeling game data, with automatic source code generation that reduces the load on programmers and eliminates human 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.

What is Charon

It is a .NET 4.6 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 and via Mono on macOS and Linux.

How it works

You create an empty gamedata.json file when launching the Charon.exe application, which acts as an HTTP server. You edit your game data in the UI, then generate source code for your game engine. With this source code, you load gamedata.json into your game and use it in a safe and structured manner.

If you use plugins for Unity or Unreal Engine, it is a little bit easier than shown in the diagram.

Editor's UI

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
