Code Comparison: LunyScript vs Engines

Comparing code for beginner’s tasks demonstrates how LunyScript reduces cognitive load and boilerplate code when learning game engine programming.

LunyScript encourages exploration and experimentation in a safer environment without feeling overwhelmed. This actively prevents self-learners from entering the unproductive comfort zone we call tutorial hell.

Quick Summary

LunyScript is 3-5 times less verbose than GDScript!

Note: C# code LoC is slightly less than GDScript when not counting braces.

Direct Code Comparison

Engines Compared:

• LunyScript (Cross-engine C#, Proof of Concept API)
• GDScript (Godot domain specific language)
• Godot C# (Godot C#)
• Unity C# (Unity C#)
• Roblox Lua (for reference)

🚧 Note: Code samples were created by AI. I spot-checked different styles and code paths, differences average out.

Key Observations

LunyScript Advantages:

1. Consistent API Across Engines
   • Same code works in Unity, Godot, and beyond
   • No need to relearn patterns for different engines
   • Skills transfer completely
2. Zero Boilerplate
   • No component management
   • No manual event subscription/unsubscription
   • No lifecycle method complexity
3. Intent-Driven Code
   • Reads like what you want to happen
   • No technical jargon barriers
   • Natural language flow
4. Automatic Management
   • UI binding happens automatically
   • Audio components created as needed
   • Event cleanup handled internally
5. Lines of Code Reduction
   • 81-82% fewer lines vs C# (Unity/Godot)
   • 71% fewer lines vs GDScript

Traditional Approach Challenges:

1. Concept Overload
   • Each task requires understanding 5-10 new concepts
   • Engine-specific terminology and patterns
   • Separation between logic and setup code
2. Boilerplate Tax
   • Null checking, component management, event cleanup
   • Manual UI updates
   • Lifecycle method understanding
3. Non-Transferable Knowledge
