Unable to create instance of C# classes #208

Open xionglingfeng opened 6 years ago

xionglingfeng commented 6 years ago

Cannot create instance of C# class in Lua.

I looked at this discussion and use the following way to export a c# class:

UserData.RegisterType<Matrix<Int32>>();
script.Globals["Matrix"] = typeof(Matrix<Int32>);

However, it complains

> Matrix.__new()
stdin:(1,12-14): cannot access field __new of userdata<System.RuntimeType>

Is the syntax changed?

Any news on this?

Someone also had the same issue in this thread and the author replied, but didn't follow through with an update after. Would like some update on this as well because I am looking at using MoonSharp for our project and this is would be quite a moderate annoyance for the use cases we have.

MoonSharp is dead just like NLua... Guess I will go back to implementing my own script host with c# scripts.

I also arrived at a similar conclusion. The library probably still works fine but the last commit was 2 years ago which is not particularly comforting. Either way, after studying whether I should use C# or Lua for scripting I found out that using C# would be much more efficient anyway since I can leverage all the IDE power I normally use and I can integrate it with very little work.

@johmarjac the point is not being dead, I wish I could have time to work on NLua, but unfortunately I am not paid to maintain the project. But on this thanks given I am trying bumping the support to Lua 5.3
