I'm trying to create a hacking game where players design programs and hack other people's stuff. Users write their programs in JavaScript. I'm aiming for a hackmud-style system, where user programs can interact with the host game, for example, transferring funds.

Trouble is, I don't know where to start. I'm using C# to develop my game. Everything I found online for using JavaScript in C# interprets the script as a program on the host computer. This is a problem because I don't want the user code to have access to the host computer, just the game. Is there a standard architecture for a project like this?

    \$\begingroup\$ @Valamorde Writing an own interpreter for a scripting language is a project which seems easy at first glance, but becomes amazingly complicated when you start looking at the details. Using an existing interpreter is almost always a better idea. \$\endgroup\$

I would recommend using Microsoft's ClearScript. This includes an examples page that will provide the basics of setting up an interface where the script will interact with your game.

I have to admit to not having used it myself (though I have considered it in the past for a game, and have used C# scripting using Roslyn instead), but looking at the Examples and FAQTutorial pages reveal that it should be a simple task to implement a way for a users script to interact with your game.
