## Meta Horizon Worlds vs. Roblox Studio: A Comparative Documentation

This document compares Meta Horizon Worlds and Roblox Studio, focusing on key features and differences relevant to content creators.


# **1. Core Creation Environment:**

## **1.1. Hierarchical Organization:**

| Feature | Meta Horizon Worlds | Roblox Studio | Similarity |
|------------------|--------------------------|--------------------------|--------------------------------------------------------------------------|
| Organization Tool| Hierarchy window | Workspace (Explorer window)| Tree structure for parent-child object relationships. |
| Purpose | Managing 3D entities | Managing 3D parts and objects | Facilitates scene management and object organization. |

**1.2. Asset Management:**

| Feature | Meta Horizon Worlds | Roblox Studio | Similarity |
|------------------|--------------------------|--------------------------|-------------------------------------------------------------------------|
| Asset Acquisition| Asset Store | Creator Store | Centralized library for acquiring reusable assets. |
| Asset Management | Assets window | Inventory | Tools for managing and organizing imported and acquired assets. |

## **1.3. Terminology Differences:**

| Meta Horizon Worlds | Roblox Studio | Notes |
|----------------------|---------------|-------------------------------------------------------------------------|
| World | Place | Represents the primary environment or game level. |
| Entity | Part | Basic building block or object within the 3D environment. |
| Asset Template | Packages/Models | Container object grouping multiple gameplay elements. |
| Transform | Transform/CFrame| Represents an object's position, rotation, and scale. |
| Hierarchy window | Explorer window | Tool for managing the scene's object hierarchy. |
| Properties window | Properties window| Tool for modifying object properties. |
| Scene window | Viewport | 3D view of the world or place. |
| Assets window | Toolbox | Tool for accessing and managing assets. |
| SpawnPoint | SpawnLocation | Location where players appear in the world or place. |
| Console | Output | Window for displaying debugging information and script output. |
| Asset Library | Creator Store | Online asset library for importing assets into a project. |

# **2. Scripting and Logic:**

## **2.1. Scripting Languages:**

| Feature | Meta Horizon Worlds | Roblox Studio | Key Differences |
|------------------|---------------------|---------------|------------------------------------------------------------------------------|
| Language | TypeScript | Luau | TypeScript is statically typed, Luau is dynamically typed. |
| Syntax | JavaScript-like | Lua-based | TypeScript has a more structured, object-oriented syntax. |
| Typing | Statically Typed | Dynamically Typed| TypeScript provides compile-time type checking, Luau does not. |

**2.2. Script Execution Models:**

| Feature | Meta Horizon Worlds | Roblox Studio | Key Differences |
|--------------------------|-----------------------------------|-----------------------------------|------------------------------------------------------------------------------|
| Script Types | Default (Server), Local (Client) | Server, Client, Module | Meta Horizon Worlds simplifies to server/client, Roblox has explicit modules. |
| Execution Context | Server or Client | Server, Client, Reusable Module | Roblox offers more granular control over script execution. |
| Local Script Ownership | Manual assignment via code | Automatic | Roblox handles local script ownership automatically. |


## **2.3. Language Comparison Example (Sum Function):**

**Luau (Roblox):**

```lua
-- Sum numbers up to "n" and returns the sum
function sumUpTo(n)
local sum = 0
for i = 1, n do
sum = sum + i
end
return sum
end

print(sumUpTo(5)) -- Output: 15 (1 + 2 + 3 + 4 + 5)
```

**TypeScript (Meta Horizon Worlds):**
```ts
// Sum numbers up to "n" and returns the sum
function sumUpTo(n: number): number {
let sum = 0;
for (let i = 1; i <= n; i++) {
sum += i;
}
return sum;
}

console.log(sumUpTo(5)); // Output: 15 (1 + 2 + 3 + 4 + 5)
```

## **2.4. Script Type Comparison**

|Meta Horizon Worlds|Roblox|
|---|---|
|Script in Local Execution Mode|Client Script|
|Script in default Server Execution Mode|Server Script|
|Export functions/classes in any script|Module script|

# **3. Asset Pipeline and Interoperability:**

## **3.1. Asset Import:**

| Asset Type | Meta Horizon Worlds File Formats | Roblox Studio File Formats (Exported) |
|------------|-----------------------------------|--------------------------------------|
| 3D Model | .fbx, .png | .obj |
| Audio | .opus, .wav | N/A |
| Material | .png | .mtl |
| Skydome | .png, .exr | N/A |
| Texture | .png | .png |
| Text | .json | N/A |

## **3.2. Roblox to Meta Horizon Worlds Conversion:**

* **Direct Conversion:** Limited. Only .fbx assets can be directly imported.
* **Native Roblox Parts:** Require conversion to .fbx using tools like Blender.
* **Scripts:** Luau scripts are incompatible; require complete rewrites in TypeScript.
* **Exporting Roblox Assets:** Roblox exports models as .obj and materials as .mtl.
