Setting up Roslyn Parser In Unity

-
So, I did manage to get the Roslyn C# Parser partially running, on the last commits of the Proof development. Now I'm putting Roslyn back in.  As I'm finding the same hurdles I thought I would call them out more clearly for others to tread.
Generated on WordClouds.com, from sample C# parsed by Roslyn SyntaxTree

First off, it wasn't a straight forward install, of just add this package and go. The first step was to install NuGet for Unity, as found here: (https://github.com/GlitchEnzo/NuGetForUnity). Instructions and download are there. Keep in mind: NuGet Packages are typically designed for Visual Studio solutions, but this is Unity. Many packages will not work out of the box. Roslyn is no exception.

So now, with NuGet running, we need to pull in Roslyn. Search for "Microsoft.CodeAnalysis.CSharp" and pull it in. Once done, there will be a handful of errors, relating to references being missing or incompatible.  So now we need to fix those errors.

Now, at this point, I should say that these errors disappear when you clear the console, unlike syntax errors. To get a list of them to show up again, you need to try playing the scene.

Next, there are different "Microsoft.CodeAnalysis.Analyzers.resources.dll" files for different languages or regions. NuGet puts them all in place, and normally, Visual Studio can sort this out, but Unity is not equipped for it. To clear this, find and delete the folder, "Assets/Packages/Microsoft.CodeAnalysis.Analyzers.2.9.6/"

Now find the folder "Assets/Packages/Microsoft.CodeAnalysis.Common.3.4.0/lib/netstandard2.0/". Delete all the sub folders.  And then again for "Assets/Packages/Microsoft.CodeAnalysis.CSharp.3.4.0/lib/netstandard2.0/".

Now, if you try playing, it should not throw exceptions.

I plan to update this with a sample video or two of how it was setup, and what initial tests I put it through, along with the code for parsing a full syntax tree.

    Ran this again on the new setup. There are some changes, but its mostly the same. Notedly, after installing the nuget package, I must remove NuGet, since its current design keeps putting the deleted files back.

C# Parser and Code View

I don't have any Proof of Concept in place yet on this, but I've finally started designing how the code editor UI will work, then designed some of the basic architecture needed to support how the UI would work, and finally, this lead to how I need to protect the user from dangerous code (you can write C# to format your machine, or try to steal memory from other apps like passwords), while also improving the debugging and teaching abilities. Alright, so I'm planning on having Classes exposed, as an item, then under the class view, is a list of items, like fields, properties, methods, etc. When selecting one of the members, you get details like notes, title, version history; for beginner coders I felt giving them a really easy ability to step back a version or two to something that last worked. Then show the code.  To be able to provide physical system responses, we need to detect all sort of things, like an infinite loop. In the case of an infinite loop, we don't

A Momentary Lapse of Passion

There have been so many projects that I have lost passion for while developing, that a few years ago, I challenged myself to start paying close attention to this. To start researching the psychology of what drives me to and from a goal. In that time, I found that Game Design is actually a key value in life's success. And Codavore will survive because of this. :D I'll tell you a short story of why I lost my passion for Codavore and then how I revived it. In hopes that when you hit this runners wall, you might be able to get past it as well. source:  https://pixabay.com/photos/light-bulb-idea-creativity-socket-3104355/ 2 weeks ago, I wanted to start working on the dialogue system, as that would be a common need in this game. I had seen the start of an instructional video on how another person had created this really nice looking Dialogue Graph, and kept looking for opportunities to apply it (or similar) in my code. So my first steps into the dialogue pushed me into worki

How to Setup a Multi-Scene Unity Project for Startup

Scene loading played an important role in this, and I believe my approach is pretty sound and proven highly useful. Let me know what you think, and what ideas you tend to apply for handling this. When developing in a multi scene project in Unity, one of the most annoying things I've worked with in the past, is the need to boot into the right place. I've worked with and developed dozens of different approaches, most of which falling into custom menu options, or resetting the default loading scene. I want to share a solution I had that is simple, small, and has worked great. General Overview Codavore is broken into several scenes BootStrap, Ui and Level/Scene/Room. Boot Strap guarantees the order of several things like my service locator and a few others. Next there is the Ui, which contains the menus and such. And finally, we have the scene with the content for the game I'm on. There is a fourth, "DontDestroyOnLoad" where Unity puts all its don't destroy object
