Question 1

How does MoonSharp compare to NLua?

Accepted Answer

MoonSharp is written entirely in C# with no external dependencies, offering better integration and built-in debugger support, while NLua often relies on native Lua libraries. MoonSharp is more focused on Unity and modern .NET platforms with easier setup.

Question 2

Can I use MoonSharp with Lua 5.3 scripts?

Accepted Answer

No, MoonSharp is based on Lua 5.2, so scripts using Lua 5.3 features like integers or bitwise operators will not be compatible. It's best suited for Lua 5.2 code or new projects adhering to that version.

Question 3

How to debug Lua scripts in MoonSharp with Visual Studio Code?

Accepted Answer

MoonSharp supports the Debug Adapter Protocol; install the separate VSCode debugger package and set up remote debugging to add breakpoints, step through code, and inspect variables in your Lua scripts seamlessly.

Question 4

Is MoonSharp good for sandboxing untrusted scripts in C#?

Accepted Answer

Yes, MoonSharp allows easy opt-out of Lua standard library modules to control script capabilities, making it effective for creating secure sandboxed environments, though careful configuration is needed to prevent access to sensitive CLR objects.

Question 5

What are the performance implications of MoonSharp in Unity?

Accepted Answer

MoonSharp runs on IL2CPP and AOT platforms, but as a managed code interpreter, it might have overhead compared to native solutions. However, its runtime code generation helps optimize interop calls, and bytecode loading can improve parsing speed.

Question 6

How to call C# async methods from Lua in MoonSharp?

Accepted Answer

MoonSharp supports async method interop; expose async methods to Lua scripts, and they can be awaited directly, as mentioned in the README, enabling asynchronous operations without blocking the main thread.
