UnityScript 2 CSharp conversion tool

Thank you so much Adriano

Your workaround worked fine !!

 

I'm really impressed. The converter worked pretty well, my js are all replaced by cs and even floating values are kept.

Very good job !! Thanks !!

 

Hi Guys,
I've just bumped into a project that uses boo, will this converter also support that?

Cheers,

Stefan

 

Cool, I was hoping that it would be something along those lines. I'll review the codebase a little further to see if it's reasonably straight forward to do a manual conversion.

Thanks for your quick reply!

Stefan

 

Hi,I have a problem for this tool on here.
Can anybody help me?

Thanks!

 

Hi Adriano,
When I replaced your updated script with the original script and ran it again, the whole transformation process went smoothly and I finally got the C# script I wanted.
That's great!
Thank you very much!

Hello,
I've been trying to convert a project with this program. The project seems to work fine and builds successfully, but when I try to convert it, I run into this error. I've tried running it within Unity and via the command line:

Code (CSharp):

1. UnityScript2CSharp was not able to convert your project:.
2.  
3. UnityScript2CSharp 1.0.7095.26335
4. Converting 'Runtime' (126 scripts)
5. Object reference not set to an instance of an object
6. Consider running converter with '-i' option.
7.  
8. UnityEngine.Debug:LogError(Object)
9. UnityScript2CSharpRunner:ShowConversionResultsInConsole(Int32) (at Assets/UnityScript2CSharp/Editor/UnityScript2CSharpRunner.cs:236)
10. UnityScript2CSharpRunner:RunConverter(String) (at Assets/UnityScript2CSharp/Editor/UnityScript2CSharpRunner.cs:215)
11. UnityScript2CSharpRunner:Convert() (at Assets/UnityScript2CSharp/Editor/UnityScript2CSharpRunner.cs:97)

This may be an issue within the project itself, as I'm not too familiar with the project. I tried running it in unity 2017.4.30f1 and ran into the same error.

I've attached the full editor.log file as well as the generated response file.

 

Hi Adriano,

That seems to have fixed the issue. Thanks!

 

Hi Adriano
is there any for 2019.1 version of unity?

 

when i click on convert, following error occur. unity version is 2018.1.0f2.

I know I'm pretty late to the party here, but I tried to start up my project after a hiatus and found out unityscipt is dead.

So when I try to convert using the integrated tool, I'm getting an error.

NullReferenceException: Object reference not set to an instance of an object.

... I tried downloading older versions of it and it tells me:

UnityScript2CSharp was not able to convert your project:.

I'm kind of at a loss at where to go from here. I dont really understand how to use the command line .exe.

 

Thanks for taking the time. I'm using 2018.1.0f2. First I tried UnityScript2CSharp_Conversion_1.0.7095.26335. That got me this in the console:

I then tried Conversion_1.0.6834.38141, and that got me this in the console:

I'm attaching the editor logs for both. I really appreciate the help.

 

well. totally unexpected running into this. 5.6.6 didn't start properly. 2017.4 loaded my old project (5.4.something) with an empty compelling error. unable to load your unityscript2csharp converter. stuck! after a while I got it: no unity script with catalina! okay. i had to find out how to get and install mojave on a virtual machine. installed 5.6.7 and imported my scene - no fixes needed. installed 2018.1 than and imported my scene saved with 5.6.7 - still no fixes needed. loaded your unityscript2csharp converter - latest version. fine.

but first I had to fix some permissions like mentioned here. no big deal.

than I ran into the same "The version of Unity passed as the Unity Editor path is too old." problem lasco described in june last year. even with the actual version of the converter. but ...

the workaround worked for me too! at the end i'm in 2019.2 on catalina with my old project. there are some smaller fixes to do. but the app is running and i can investigate now how chaotic my scripting was six years ago =;°0 ... and i have to thank you so much for the work you have done, adriano. it took me some time to investigate and find a way that worked but this is nothing compared to rewrite all that code (and understand the crude logic behind what me and my scripting partner at this time have done long time before). could be easier off course. but saved my time at the end. thanx.

 

Got this error in my Unity 2018.1.2 project:
Any idea what might cause it?

Hello Adriano,
I've tried with the lastest 2018.1.9 and the error disappeared. Now I have another errors: "Ambiguous reference"
- I've tried to solve it by including at the beginning of the script "import UnityEngine" but it still gives me the error.
The ambiguous reference include the following:
Vecotr3,
Range,
SpringJoint,
Camera,
AudioClip,
AudioSource,
Material,
RigidBody,
Collider

basically all UnityEngine related items
How would you solve that?

Thank you

 

Hi Adriano,
when I use once script at a time in the 2018.1.9 project the converter is working.
The issue starts when using multiple scripts at once.
This is the Editor log after running the converter with verbose logging:

UnityScript2CSharp was not able to convert your project:.
[UPDATE] will add a full log file.

 

Hi Adriano,
Yes, I saw this message, currently working on something else. Will send the Editor.Log file when back on that project.

 

Hello Adriano, I am attempting to update an old project with many js scripts. I'm on macOS Catalina using 2018.1.9f2.
Attached is my log file.

I am receiving this error:
UnityScript2CSharp was not able to convert your project:.

Converting 'Runtime' (189 scripts)
Object reference not set to an instance of an object
Consider running converter with '-i' option.

UnityEngine.Debug:LogError(Object)

UnityScript2CSharpRunner:Convert() (at Assets/UnityScript2CSharp/Editor/UnityScript2CSharpRunner.cs:97)


Thank you for any help you may have and stay healthy!

 

Thank You!

Here is the Verbose Logging file. I am using the latest version of the conversion tool.

How do I select the '-i' option?

Let me know if you need anything else. Thank You. Glad you are healthy.

 

Ok, I attempted to run the conversion tool on my Windows machine. Still no luck. Here is the verbose editor log.

 

I don't need comments.
I tried the suggestion but the tool still quits right after it begins. Now it doesn't give me an error in the console.

 

This is what I found.

 

Hi Adriano, Thanks for your suggestions. I was finally able to make it work by removing a few lines of offending js code - exporting the entire project as a package, then importing package into a clean new project. I converted it now. Thank you for the help.

Hi,

I tried installing it on a fresh version of Unity 2018.1.9, but I don't see it show up anywhere in the menu. What am I missing?

I'm running MacOSX 10.13.6 with Unity Hub and the latest Unity 2019 + visual Studio.

This is needed to upgrade an old game that was created in a perpetual licensed Unity 4.

Thanks
Will

 

Hi, Adriano

Nothing showed up in the console when I tried installing the package. (Where is that file? Please tell me where to look for it, because I found nothing relevant when searching for 'Editor.log' in the project folder and in the ~/Library folder.)

In the meantime I created an empty new project and tried installing the tool. This worked - so Tools showed up. I then tried pushing only some of my .js scripts into that project and tried to convert - this produces errors - so I assume the tool doesn't operate on scripts by themselves?

Here's the error, which seems to want a dll file:

UnityScript2CSharp was not able to convert your project:.

Cannot find referenced assembly: Library/ScriptAssemblies/Assembly-UnityScript.dll

UnityEngine.Debug:LogError(Object)
UnityScript2CSharpRunner:ShowConversionResultsInConsole(Int32) (at Assets/UnityScript2CSharp/Editor/UnityScript2CSharpRunner.cs:236)
UnityScript2CSharpRunner:RunConverter(String) (at Assets/UnityScript2CSharp/Editor/UnityScript2CSharpRunner.cs:215)
UnityScript2CSharpRunner:Convert() (at Assets/UnityScript2CSharp/Editor/UnityScript2CSharpRunner.cs:97)​

Also, I quit Unity 2018 and started it again. The 'Tools' menu item is missing again. Deleting the Package and reimporting it doesn't solve the issue.

Will

 

Adriano, I started a conversation with you and uploaded the file there.

 

I just found this thread, so I'm sorry about the duplicate post elsewhere.

I just updated some old UnityScript projects to Unity 2018.2.21f1, the last Unity version to support US. I did this in preparation for converting the US projects to C#. I was thinking they should be updated to the latest version that supports US. But when I imported the conversion package, UnityScript2CSharp_Conversion_1.0.7264.28836 (https://blogs.unity3d.com/2019/01/08/unityscript-to-c-conversion-tool/), it tells me I have to be running 2018.1, the last Unity version (it says) that supports US. I tried opening one of the projects in 2018.1, but it doesn't look like that's going to work, the 2018.2 project does not import correctly in 2018.2 (a bit surprising).

If I run the conversion in 2018.2, it says "UnityScript2CSharp was not able to convert your project," and gives a long list of Unity files. Is there a newer version of the conversion utility that works in 2018.2? Or can the existing scripts be updated?

One thing I tried is changing a line in the conversion script from 2018_2 to 2018_3, but still got the same result, not able to convert the project, no other errors, just a list of files:

Code (CSharp):

1. #if UNITY_2018_3_OR_NEWER
2.         EditorUtility.DisplayDialog(Title, string.Format("You are using Unity version {0}.\r\n\r\nThis verion of Unity does not support UnityScript. Use versions 2017.3 ~ 2018.1", Application.unityVersion), "Ok");
3.         return;
4. #endif

I can't find any other mention of a 2018 version in the scripts, though there are several checks for UNITY_2017_3_OR_NEWER. I don't know what else in the scripts need to be changed.

This is kind of a big deal to me, as I just spent months updating 61 projects that have not been updated since Unity 5.x (a few in 2017.x). I got them all up and running in 2018.2, and now I'm stuck. It looks like I can't open 2018.2 projects in 2018.1, and I can't run the conversion tool in 2018.2.

If there's not an updated version of the conversion tool or a way to make it work, is there a way to downgrade my projects to get them to open in 2018.1? Surely there must be a solution. I've invested way too much time in this effort to hit a dead end at this point.

 

I sent you the Editor.Log contents in a private message. Couldn't find the US2CS_*.log file.
