CORP Documentation - Monolisk Documentation

Reading time: ~15 minutes

CORP (Component-Oriented Replicated Programming) is a powerful game development framework for Roblox built with roblox-ts. It provides a Unity-like ECS architecture with GameObjects and Components, along with a built-in networking system inspired by Unity’s Netcode for GameObjects.

🚀 Quick Start

Get up and running in minutes:

Install Required Tools
- Install VS Code extensions:
  - roblox-ts
  - Rojo
- Download and install Rojo Studio Plugin (Rojo.rbxm)

Clone the CORP Template

git clone https://github.com/MonoliskSoftware/CORP-TEMPLATE
cd CORP-TEMPLATE
git submodule update --init --recursive
npm install

Configure your game Update GAMEPACKS/MYGAME/metadata.ts:

const metadata: Gamepacks.Config.Metadata = {
    name: "MyGameName",  // Change this
    // ... rest of config
};

Update GAMECONFIG/gameinfo.ts:

const gameinfo: Unreal.Gameinfo = {
    rootPack: "MyGameName",  // Must match metadata name
    authority: Unreal.Authority.SERVER
};

Create your first component In GAMEPACKS/MYGAME/src/:

import { Behavior } from "CORP/shared/componentization/behavior";

export class HelloWorld extends Behavior {
    public onStart(): void {
        print("Hello, CORP!");
    }
    
    public willRemove(): void {}
    protected getSourceScript(): ModuleScript {
        return script as ModuleScript;
    }
}

Export your component In GAMEPACKS/MYGAME/exports/components.ts:

const components: Config.Components = {
    mappings: {
        "hello_world": HelloWorld
    }
};

Start Development Terminal 1 - Start Rojo:
rojo serve default.project.json
Terminal 2 - Watch TypeScript:
npx rbxtsc --watch
Connect Roblox Studio to Rojo and press Play!

✨ Features

🎮 Unity-Style Architecture

Familiar GameObject and Component patterns for organized game development.

const player = new GameObject("Player");
player.addComponent(PlayerController);
player.addComponent(HealthSystem, { maxHealth: 100 });

🌐 Built-in Networking

Automatic replication with NetworkObjects and NetworkBehaviors.

@RequiresComponent(NetworkObject)
export class PlayerSync extends NetworkBehavior {
    public readonly position = new NetworkedVariable<Vector3>(Vector3.zero);
}

📡 Type-Safe RPCs

Remote Procedure Calls with flexible configuration.

@RPC.Method({
    endpoints: [RPC.Endpoint.CLIENT_TO_SERVER],
    accessPolicy: RPC.AccessPolicy.OWNER
})
public attack(targetId: string): void {
    // Server validates and processes
}

🔄 Automatic State Sync

NetworkedVariables, Lists, Maps, and Sets synchronize automatically.

public readonly health = new NetworkedVariable<number>(100);
public readonly inventory = new NetworkedList<string>();
public readonly scores = new NetworkedMap<string, number>();

🎬 Scene Management

Load and manage game scenes with serialization support.

const scene: SceneSerialization.SceneDescription = {
    children: [
        {
            name: "Player",
            components: [
                { path: ["src", "components", "PlayerController"], data: {} }
            ],
            children: []
        }
    ]
};

🎯 Component Lifecycle

Predictable initialization and cleanup with lifecycle hooks.

export class MyComponent extends Behavior {
    public willStart(): void { /* Pre-init */ }
    public onStart(): void { /* Initialize */ }
    public onPropertiesApplied(): void { /* React to config */ }
    public willRemove(): void { /* Cleanup */ }
}

🔑 Key Concepts

GameObjects

Entities in your game world that contain Components.

const enemy = new GameObject("Enemy");
enemy.setParent(parentObject);

Components

Define behavior and data for GameObjects.

export class MyComponent extends Component {
    public onStart(): void { /* Initialize */ }
    public willRemove(): void { /* Cleanup */ }
}

Behaviors

Components with serialization support.

export class MyBehavior extends Behavior {
    @SerializeField
    public configValue: number = 10;
}

NetworkObjects

Make GameObjects replicate across the network.

const netObj = player.addComponent(NetworkObject);
netObj.spawn(); // Server only

NetworkBehaviors

Components that replicate their state.

@RequiresComponent(NetworkObject)
export class MyNetworkBehavior extends NetworkBehavior {
    public readonly syncedValue = new NetworkedVariable<number>(0);
}

🎯 Best Practices

✅ Do

Use Behavior for most components (serialization support)
Initialize in onStart(), not the constructor
Use @RequiresComponent for dependencies
Let server make authoritative decisions
Use batched replication when possible
Clean up resources with collector

❌ Avoid

Accessing components in constructor
Modifying NetworkedVariables on client
Using instantaneous replication for frequent updates
Forgetting to call super() in constructors
Serializing runtime state (use configuration instead)
