A few questions about MiniScript.

benzy54

I have been looking into MiniScript for a project I am working on and I have a few questions.

1) How well would mini script work with Unity Job System and multi-threading.

2) Are the calls and infrastructure of MiniScript using classes or structs?

1) It works fine with multi-threading. I don't know that any one has tried it with the Job system, and I don't have any experience with that myself. But it's pure C# code, and thread safe, so I'd think it ought to work.

2) It's mostly classes. You can inspect the code yourself at the github repo, which is always the most up-to-date version of the MiniScript engine. (Look in the MiniScript-cs folder; MiniScript-cpp is the C++ version.)

The only advantages of buying the Unity plugin are (1) you get a code editor (the same one used in Mini Micro), and (2) you help support development of the language. 🙂

Thanks for the reply. Another quick question.

I would like to use Miniscript as a repository of custom functions that I can access and call in my C# code. I am spending some time in the documentation and can't seem to find a good example of this.

Example:

string miniString = @"
testVal = function(val=1)
return val + 1
end function";

    Interpreter myInterpreter = new Interpreter(miniString);

    myInterpreter.Compile();
    myInterpreter.SetGlobalValue("val", new ValNumber(5));
    myInterpreter.RunUntilDone();
    ValNumber newval = myInterpreter.GetGlobalValue("testVal") as ValNumber;

    Debug.Log(newval.ToString());

This is not working so far. It can't find "testVal". Any help would be appreciated.

It would be awesome to hold a pointer to a compiled function and run/use it with a call giving it parameters ect.

Your example runs code that defines the function. But nothing actually calls the function. When you call GetGlobalValue, you're just getting back the reference to the function, not the result of calling it.

From what you describe, I think what you want is something like the "Event Pump" example in the Unity Integration Guide. (If you're not using Unity, that's OK, this section still applies to you.)

Also, I might be able to help you better if you join our Discord — I see messages there right away if I'm at my desk, instead of hours later when I check my email or the forums. Just a thought. The link, if you want it, is at the bottom of https://miniscript.org .

Can't wait to hear more about your project!
