Hi Guys,

First beta release was submitted to Asset Store.

 

Holy S***....this is what i was waiting for countless years ! Great job man! When do you think will it be released ?

 

Thank you. I'm glad to hear you like it. And if you want get beta package, pm me with your email or drop an email to me (amlovey@qq.com), I will send it to you.

And for the release date. its up to Asset Store review team since I have already submitted for review. I guess it may be next week.

 

This definitely seems very cool. Good luck with this I'm sure I'll check it out upon release.

 

Thank you. PM me with your email or drop me an email If you want to try it before release. I will send you the beta package.

 

I have two questions: 1) Apart from the integration in the Editor and the ping to the current opened document, what are the advantages of your asset compared to using Visual Studio Code directly? 2) What is the price of the asset?

 

Thanks for your questions.

For #1, this assets is smaller than VSCode, easy setup, and it can interactive with Unity Editor (Ping document is a sample) and focus on Unity Programming... VSCode is great but it's a code editor for all developers, not only for unity developers.

For #2, I want to set it to $10 in beta phrase, but not sure after that..

 

I just tried to install the beta. There is a thing called "omniSharp". This is something apart from Unity, and meant to be installed just for your windows version, to get uCodeEditor working ?! Is this really needed, in the final version ? Also i have to install NET 4.6. Is this also necessary ? I would like it, to have a uCodeEditor install just inside Unity and no other stuff for Windows, when possible (portable style).

 

Omnisharp is required, not only on windows, but also on macOS. It's the engine that powers C# language features.
For the .NET 4.6 issue, I think it's introduced by a tool developed by me, I will try to make it as not required if possible.

Thank you very much for your feedbacks.

 

Okay. But omnisharp is portable, for windows ? As far as took a look, it was zipped without an installer. I like the portable way. And would be great if we don´t need to install NET 4.6

 

Yes, uCodeEditor packages already include the Omnisharp in it for both of Windows and macOS, no extra download actions required. And I will try to remove the .NET 4.6 required.

 

Debugger?

 

Have no debug support for now. May be in future if it's possible do that.

 

I'm sorry. I can't imagine a workflow where I'd want to edit code and not be able to connect it to debug. I guess if you have other members of the team that are no programmers and you quickly need to fix something then maybe, but a lot of the time, even then, I need a debugger on their machine to be able to diagnose a problem first.

 

Yes, Debugger is very useful in that case, but may be it's not required fo all cases. As far as I know, most of my friends don't use debugger in their daily work, espeically who works on macOS platform... But I do agree with you that Debugger is a very important component. I will try to add it if possbile in future. For now, uCodeEditor is a code editor, after adding the Debugger, we can call it as an IDE then

 

i'd also use this for fast coding only, if i need debugging ill just start VS then..

questions
- is there some way to show matching brace lines?
- or jump to matching brace?
- also can i set custom shortcut keys? (say for "autoformat document" to be F12)
- is there duplicate line shortcut key or can i add it? as in ctrl+D, would duplicate current row

 

#1. Yes, it has an action named 'Go To Bracket' can jump to the matching brace line
#2. Yes jump to matching brace
#3. Have no such feature in beta, but it's possible to do that. May be add it in later release.
#4. Yes, have duplicate line shortcut.

For correct shortcut settings for specific action, it's not easy inside Unity Editor. Because Unity Editor have many shortcuts which can cause shortcut conflict...

 

uCodeEditor is available on Asset Store now: https://www.assetstore.unity3d.com/#!/content/117349

 

The .NET 4.6 issue is fixed. And it will be included in next beta release 1.0.3b, which will available next week in my plan.

 

Okay....very fast and very cool

 

Beta 1.0.3b is pending review now. Below is the release note:

NEW:
- Add Auto Save support, we can turn on/off it in Settings Window
- Add cursor navigation history support, see the commands `Move Cursor to Previous Positon` and `Move Cursort to Next Position` in Command Palette
- Add settings for tabSize and insertSpaces formatting options for Shaderlab in Settings Window
- Add `Sync With Project` button in Main UI, it can save all document automatically and then trigger a recompile to make project update to date
- Add an new color theme `Monokai`
- Add Region support for CSharp and Shaderlab.
- C#: using `#region` / `#endregion`
- Shaderlab: using `//region` / `//endregion` or `//#region` / `//#endregion`
- Add commands for help information, like online documents, tips and tricks

Bug Fix:
- Fix open file will be failed in some cases
- Fix content of opened documents will be overwrote in some cases
- Fix insert text is not correct after press enter key in xml document comments in C#
- Remove .NET 4.6 dependency on Windows

 

maybe related to autosave,
so if unity suddenly crashes (during entering playmode or maybe during some bad import),
will the currently unsaved code be saved?

and is there some risk of losing some code if it crashes while its actually saving the script data?
(although probably quite small change of happening exactly at the same time)

 

uCodeEditor will save the unsaved scripts before entering playmode automatically and saving logic have no changes to cause unity editor crashes. If autosave turn on, uCodeEditor will save data after script changes, this happen before importing assets. If autosave turn off, bad import may cause script changes lost.

If there are something external make Unity Editor crash while the saving process is running, that will case data lost, because the saving is not completed... But that will be very very very little chance for that happen, because saving process will be completed in very short time, which is less a second normally.

 

Hi, Beta 1.0.3b is available on Asset Store now. And in my plan, text search in all files feature will be the main update for next beta version. Thanks.

 

put the theme of youtuber brackeys ...

@Amlovey any plan to support 2017-18 plus? i cannot open an existing scripts under unity 18.1

 

I'm develop uCodeEditor in 2017, it shoud be support. May I ask you the version number of your Unity 2018 Editor?

And may I ask you try restart Unity to see If it works after restart or not. Thank you very much!

 

2018.1.0f2 and yes i did restart the editor

 

Thank you, I will setup a environment and try to repro it. I will back to you after that.

 

Hmm testing it in empty project on 2017.2.1p2 and 2018.1.0f2 same result, can't open scripts/shader. Always ended up untitled file

 

@Reanimate_L I digged into code and found there is a bug on windows platform. below is the fix:

in file uCodeEditor/Editor/CoreWebviewComService

change line 100:

from

Code (CSharp):

1. if (!File.Exists(temp[0]))

to

Code (CSharp):

1. #if UNITY_EDITOR_WIN
2. if (!File.Exists(temp[1]))
3. #else
4. if (!File.Exists(temp[0]))
5. #endif

will fix the bug.

 

yep that fixed it, awesome

 

Glad to hear it works on your side. I also submitted a new packages with the fix to Asset Store.

 

@Amlovey oh a request if you don't mind. hlsl support, since SRP are using hlsl now

 

That's a big topic i think. Email may be better than forum post to discuss it. Would you mind drop me email with more details? my email is amlovey@qq.com.

 

Oh nevermind, it's from my side. uCodeEditor did support opening hlsl. I just forgot to apply the fix for windows on another project. It's all good now.

 

New packages with fix of open scripts issue was declined by Asset Store team... I have made some changes by following Asset Store team guideline and resubmitted it with bumping up to the version number 1.0.6. It's the first non-beta release and price was changed.

Below is the release note of the new version 1.0.6:

- Fix open scripts failed on Windows platform in some scenarios.
- Fix go to file feature got an empty list in some scenarios.
- Fix color theme dropdown list scroll bug in Settings Window.

 

Version 1.0.6 is available on Asset Store now.

Bug Fix:
- Fix bug that window become no response after scene file reloaded.
- Fix xml document comment format for property of CSharp.

 

Just found out about this, and it looks awesome.

One question / request

Can it edit csx files (and run them)

The workflow I have in mind is to create small scripts to process some assets, or to modify some objects in the hierarchy, and I don't want to create an editor class and menu item every time.

So i'd use this kind of like a REPL

 

Hi @rawna,

uCodeEditor does not support edit csx files and run them for now, but it's possible do that because Omnisharp does support csx file. CSX support is a big topic i think, would you mind send me email to me? let's discuss it using email.

Thanks,
Amlovey

 

Version 1.0.8 is submitted to Asset Store.

NEW:
- Add `Unity Editor: Go To Scene...` action to quick open scene in Unity Editor.
- Add `Unity Editor: Reveal Special Folder...` action to reveal Unity special folder, like Application.dataPath, Application.persistentDataPath, Asset Store Packages Folder etc.
- Add Unity 2018.2 support. We can open file in packages folder as readonly file in uCodeEditor and highlighting for .uxml, .uss, .xsd files.
- Add .csx editing support.
- Add file icons.

Improvement
- Record cursor line to instead of cursor position for cursor navigation history.
- Improve C# Highlighting with async/await keywords support.

Bug Fix:
- Open file with line failed in some scenarios.
