Converting Code from JavaScript to C#

Question

What is the best means of converting JavaScript to C Sharp with a minimal amount of user interaction, meaning one that best converts the code without the user having to fix much of the code. Right now I use the converter at "http://www.m2h.nl/files/js_to_c.php", it works for the most part but it can't properly convert "var" over to C# and you must then specify a specific variable as that is what C# requires compared to the more openness of JavaScript variables. Such as when I convert the following code:

As you see, the "var" parts get turned into "FIXME_VAR_TYPE" because it doesn't know the proper var, is there any list of any kind showing the differnet variable types you can use or could someone please tell me the proper things to put in those spots. And should I make the "Array" places into "Array List"? Any help or another converter would be appreciated.

Answer 1

Actually, converting UnityScript to C# is probably best done via a .NET reverse compiler, of which there are quite a few available. Simply put the UnityScript file into Unity and let Unity compile the file. Then, grab the bytecode DLL from the folder [yourProject]/Library/ScriptAssemblies

Then, finally, take a .NET reverse compiler like .NET Reflector, use the DLL (it's called "Assembly - UnityScript.dll", or, if you have editor scripts in UnityScript you might need to look for the file "Assembly - UnityScript - Editor.dll"), look up the class in the tree, do disassemble on it, and show the methods - there you go.

What you get there is perfect C# code that will compile without any problem (well, it is compiled already). The only thing that will be missing is the comments; but you could easily copy those over if you really need them (obviously depends on what you want to use this for).

This is also a very interesting way to figure out how certain things in UnityScript/JavaScript are actually implemented in bytecode (it's sometimes good to know because sometimes, UnityScript will "look very simple" but produce code that's simply less than perfect ;-) ).

All of the FIXME_VAR_TYPE instances in the code are either bool, string or int (should be fairly easy to work out which is which)

And yes - you'll need to change Array to ArrayList, though that should be the only change I think seeing as ArrayList has Add just the same as Array

I don't think there is another convertor, so that's the best you're going to get (and I'll be honest, it's pretty damned good considering unity's javascript isn't much like other javascript implementations)

If you need to search for a list of types, MSDN has a pretty long list you can look through

Answer by fherbst · Jul 05, 2010 at 09:29 PM

You should change

public var gameName = "Example4";
public var serverPort =  35001;
...
public var filterNATHosts = false;

to

public var gameName : String = "Example4";
public var serverPort : int = 35001;
...
public var filterNATHosts : boolean = false;

and so on.

I don't know why #pragma strict does not complain about it (probably because you assign the variables directly), but if you tell javascript what type the variables are, your converter will know it, too.

It's not mandatory when the compiler can infer the type, so #pragma strict doesn't and shouldn't complain about it. Works exactly like var in c# 3 (which is probably going to make convertors much easier to write when unity 3 is released)

Thanks $$anonymous$$ike, I thought it would be this way.

Answer 4

Answer by trepan · Jul 31, 2014 at 05:26 AM

I recently faced this same question myself and in my madness decided to write a new conversion tool...

For simple to medium complexity projects CSharpatron really will do everything necessary to fully convert a project from Unityscript to C# (e.g. I can convert the old Penelope example project in under 5 minutes with zero manual edits). For more complex projects (e.g. my own project at 107,000 lines), it brings conversion time down to a few hours with supporting tools for every step of the way.

CSharpatron is available on the Asset Store here. Hope it helps someone else.
