NLua Whitelist classes from UnityEngine namespace

Question

Trying to make a puzzle game where you write code to progress, i currently trying to get a platform to move based on players input.

I dont know how i can get the Vector3 class in without adding everything else, i know i can do lua.LoadCLRPackage (); and in lua import 'UnityEngine' but that will also add the GameObject class and allow the users to hijack items they are not suppose to reach.

My idea at first was to make a white-list namespace that only the classes i want is in, but my solution dident work.

 using UnityEngine;
 namespace Whitelist{
     public class Vector3 : UnityEngine.Vector3{}
 }

Because Vector3 is sealed, any one have an other idea i can try?

Answer 1

Ended up doing a huge blacklist file of all the classes in UnityEngine based on the API Documentation, there might be hidden classes that i have missed. Just comment out (LUA style) the one you dont want, and run this before the input code.

 lua.DoString(Blacklist.list + text.mainInput.text);

 using UnityEngine;
 
 public class Blacklist
 {
     public static string list { get {
             return @"
