Livity - The Live Coding Tool for Unity

Unfortunately there are no plans for supporting 3.5.7 right now. There are a few dependencies on Unity 4.0+ APIs and features that might be just too expensive to replace.

 

Thanks for your interest, Santtu S., a c# version is already in the making.

About a possible competitor from Unity in the future all I can say is that I am not aware of any developments in that area.

And yes, debugging is in the long term roadmap for Livity, to be tackled once the community is satisfied with its live coding and coding assistance features.

Cheers!

 

Agreed.

 

Purchased Livity for Unityscript

i will wait an update that supports more than one function "per module" for the live code feature ( for now only one function is limiting ).

 

It was an insta-buy for me, but in all fairness, for now I am disappointed.

It has great potential but two things made it pretty unuseful for my intended purposes:
1) The 'only one' live function makes it nice for tweaking formulas, but that's about it. Code is hardly ever centered around one function body. I was hoping this would make me switch from my current prototyping setup in lua, which allows me to change and live change, add or remove any function from any class when reloading. It allows me to plot out the skeleton as I go, which is much more useful than being able to microtweak a function's body.
Yes, for the particle example it's nice, but not many things require algorithmic tweaking to that extent, much of that (in general) is just parameter tweaking, for which the inspector works just fine.
2) I was really assuming this came with source and thus would finally be a good way to see *how* to use the power of boo. The Unity presentation from...2010 I believe, made me drool about the possibilities of boo, but resources are scarily scarce. This asset was created by the guy that created boo, what better way to learn than from his advanced work? Alas - it's all dll's, so no way to learn, and if - heaven forbid - the project gets abandoned I am left with nothing. I know there's a git repository - could people that purchase the plugin at least get read access to that?

Don't get me wrong, I love the tech - and it's something I was pondering but is beyond my understanding of .NET, and it has massive potential, but as is it doesn't really add to my arsenal - a shame.

 

Thanks, Andrea. The one function per module limit will be lifted very soon.

 

Hi bizziboi,

Thanks for the valuable feedback.

The limit of one live function per script will be lifted very soon.

About the source code I'll consider your suggestion. Some features are already implemented as Boo code released as part of the project but It's a hard balance sometimes to decide whether to include source code as part of the project but risking it not being loaded because of project compilation errors.

In the meantime I'd like to invite you to join the Boo google group, the community there can help you cultivate your Boo-Fu.

Cheers!

 

As soon as this happends for unity.js and is on the assetstore Ill gonna puchase it.

Cheers,
Sash

 

Just purchased the UnityScript version. The instant feedback is great! I'm looking forward to seeing where you take it Rodrigo .

I have a few suggestions. I would like to be able to select an expression then activate a hotkey and have that expression wrapped in a Watch.Expression(...) call and the required import added to the script if it is not already there. Also if the same hotkey is pressed a second time with the cursor on any part of a Watch.Expression have it remove the call to Watch.Expression. Also I would like the option have Livity respect my external editor preferences with a command to selectively open in Livity. This way I can continue to use my existing editor (still Emacs ) along side Livity.

Kind regards,
Fernando

 

I'm on the same C# boat. When that comes out I'll buy no questions asked. Subscribing to this thread. This is awesome!!!

 

could not wait, purchased it for java script.

plain awesome! cant wait for the live function lifted to be used with more than one function.

everybody doing some low level scripting or in deep high level programming should purchase this tool, its worth it.
it makes coding so much more fluent and fun, even besides the live coding function.

cheers,
sash

 

Thanks, Sashimi!

I think you'll be pretty happy with the next update.

cheers,
bamboo

 

Thanks, Fernando!

Your suggestions make a lot of sense and I'll implement both in future releases (editor preferences already included in the next one).

By the way, how would you like to live code from Emacs?

Cheers!

 

Is an update to the script editor close or you are mostly working in the C# versions due to demand?

 

While I'm relentlessly working to get the c# version out ASAP I haven't forget your suggestions and requests for improvement

I'm submitting v0.1.3 right now with the following improvements:

* support for arbitrary number of live functions per script (yeah!)
* ability to select which file extensions should be handled by Livity
* CTRL+] and CTRL+[ to 'Indent Selection' and 'Outdent Selection' respectively
* show livity preferences in the Unity preferences window
* better standalone preference window organization following unity design

I'm also very close to a breakthrough that will make the whole workflow much smoother, stay tuned!

 

Thats great news, Good Job Rodrigo!
Eager to update

 

Great I'm looking forward to the next release!

That would be amazing ! Are you planning on supporting any external editor or adding support for specific editors? I can understand if us Emacs users are not high on that list

Btw, Livity reminded me of a Bret Victor presentation that I think I found via one of your tweets? Is Livity inspired by some of his UI ideas? It is exciting that you are not only working at the language level but at the tools level.

 

Hmmm, it seems I can't add local variables to the function while livecoding - will that be solved? I can see the problem with adding members or functions while livecoding (although I hope that too will be possible one day) but adding local variables would be nice.

As mentioned before, I am spoiled wrt livecoding - my Lua codebase supports adding fields and methods at runtime.
Sadly my backend engine isn't near as feature rich as Unity, and even if I hooked up Lua to get the livecoding experience, the outlook of having to port it to C#, JS or Boo afterwards isn't that tempting - this is where Livity has the huge bonus.

 

I thought so

Bret Victor's work is indeed a great source of inspiration. Exciting times!

 

Local variables are supported but currently they can't be named after members of the enclosing type. Maybe that's what you're experiencing? I'm sorry for the inconvenience, that limitation will be lifted soon.

By the way, it will be possible to add functions while livecoding, oh yes, it will.

 

Ah, it could well be I was shadoing members or globals. Given that it was a quick test there was definitely items name 'test' - so used to scoping that it hadn't occured to me.

"Yay" regarding adding functions with livecoding )

As said, I am very excited about the project's posibilities so I am hoping initial reception is great - I believe it could easily become the Asset Store's best seller once it matures.

 

Looks good, I'm interested to know how good the auto complete is in the editor, as it isn't good in monodevelop for JS and can be slow in C#?
Will it quickly bring up suggestions for your own classes variables as you type - something close to Visual Studio's Intellisense?

 

Im using UnityScript in Livity and I can tell you that autocomplete is better than monodevelop. When there is also info displayed about function arguments somehow, it will be of course even better. Go for it.

On the side note:
Rodrigo can we please have a shortcut to "Save|Refresh" or let us know how and where to define our shortcuts?
The indent update is nice

Thank you

 

Hi Nuverian,

I'm glad you liked the update, I've just submitted a new one that includes bracket matching and I think you'll like it too

Here's a quick example on how to define your own keyboard mode binding ALT+UP to TransposeLineUp, ALT+DOWN to TransposeLineDown, CTRL+S to Save and CTRL+R to Refresh.

Code (csharp):

1.  
2. import Livity.Composition
3. import Livity.Text.UI.Editor
4.  
5. [Export(IKeyboardModeProvider)]
6. class CustomKeyboardModeProvider(IKeyboardModeProvider):
7.     Name:
8.         get: "Mine"
9.    
10.     def KeyboardModeFor(editor as ITextEditor):
11.         return KeyBindings() {
12.             "&up": editor.Operations.TransposeLineUp,
13.             "&down": editor.Operations.TransposeLineDown,
14.             "^s": { editor.Operations.ExecuteCommand("Livity:Save") },
15.             "^r": { editor.Operations.ExecuteCommand("Livity:Save:Refresh") }
16.     }
17.  

Also on https://gist.github.com/bamboo/6481736 in case the formatting gets messed up.

Notice that this example will only really work on OSX since CTRL+S and CTRL+R are already taken by Unity on Windows in which case ALT+S/ALT+R could be used instead.

After saving and refreshing you can select the newly defined keyboard mode in the Livity keyboard preferences section "Default Keyboard Mode".

For a more complex example please take a look at KeyboardModes.boo shipped with Livity but of course always feel free to ask any questions here.

Cheers,
Rodrigo

 

As others have said - an instant purchase once the C# support is there.
If you need some passionate beta testers then we would love to help, too

 

Wait...UnityScriipt did get the 1.3 release with support for multiple functions and the Boo version didn't?
That's odd - and disappointing!

 

I can understand your disappointment, bizziboi but I did submit the boo update as I always do but since they are different packages they are handled separately by the asset store team and they just didn't get to it yet. Patience

 

Ah okay, I was worried you had decided to drop Boo support for lack of interest (guessing there aren't many Boo coders).

Patience......argh!

 

Livity for C# is here!

https://www.assetstore.unity3d.com/#/content/11282

And now for something completely different... Livity All-in-One!

Enjoy!

 

Fantastic !

Very good news for all.

Thank you.

 

The combo pack is an instant buy for me, despite having the boo version already. Plain awesome )

 

Absolutely amazing.

Immediately have 3 questions:

- Am I right in thinking that in order to add a method or member at runtime I have to refresh? If so, is there any way to prevent variables from being reset? (making them serialized or something or an attribute?)
- In order to make a function [Live[ I have to refresh as well, correct?

- Readme mentions a few interesting things, most importantly:
Live coding from VS: how?

Oh darn, more questions:
The REPL, can it support multiple lines? When I type def a(b): on the first line and press enter it gives me errors, shouldn't it expect a block?

Thx ) Happy as a clam, livecoding in c# and a live updating boo learning tool, what more could one want? (well, okay, I have a few wishes.....)

But as said, amazing.

 

Hello,

I've just bought the C# version

All I can say is - Incredible!!!


Thank You

Paul

 

I've just bought livity

I google before buy and I found
http://visualstudiogallery.msdn.microsoft.com/6a710382-95a2-450a-b71f-c28e50a49343

Is it working ?

 

Refuses to install for me because I only have Visual Studio 2012 and 2013 installed. Unfortunate it only works with 2010...

 

Great! Thank you very much for you support, bizziboi!

 

Yes, currently in order to add new members it is necessary to refresh, I'm working on an update that will allow new methods to be added on the fly (yeah!).

You can make fields serializable by declaring them public or by marking them with [SerializeField] attribute.

Yes.

Install the Livity Studio extension (currently only available for VS2010, VS2012 version coming soon) then:

1. Start Unity on any project with Livity for C# installed, just make sure you don't have the WebPlayer target selected and Unity/Preferences/Player/[Run in the background] is checked
2. Open your Unity csproj with Visual Studio
3. Tools/Toggle Live Coding (or CTRL+ALT+SHIFT+L CTRL+ALT+SHIFT+L)
4. Code your Live methods away! All your changes from Visual Studio will be reflected on Unity.

Just remember NOT to save the files from VS while live coding otherwise Unity will recompile the project when it gets the focus.

I'll release a new update soon with that feature.

Thanks! I'm very happy with the feedback!

 

Thank you!

 

Thank you!

Yes, currently with VS2010 only. Just make sure "Project Settings/Player Settings/Run in Background" is checked in Unity and that the WebPlayer target is NOT selected.

 

I'll be releasing a version compatible with VS2012 soon.

 

Any chance of Sublime Text integration, or would I be able to do this myself (is there a public API)? If so, I'd grab this in a heartbeat.

 

Fantastic news!
mmmm I bought the UnityScript version to try it but I use C#... Is there a way to transfer the license?

 

Got the c# version, thanks!

Using that "CustomKeyboardModeProvider", would it be possible to add F1 help,
so that it opens scripting reference (for the word where cursor is..as in uniScite) ?

And ctrl+d for duplicate line or selection?

 

Does the C# version do single-step debugging, watching variables on the fly?
Do you have a free trial version?


I'm looking to replace UnityVS with Livity. That means that it must match features found in UnityVS.
UnityVS generate Unity project files on VS, debug (but does it badly) on VS.

 

Rodrigo,

Thanks for clarifying how to make shortcuts. Usefull.

Also, here is something I found in case you want more inspiration:
http://www.chris-granger.com/lighttable/

 

Another vote for Sublime Text integration. I purchased Livity (Boo version), but I just can't see it replacing my default editor for various reasons.

 

Yes, Sublime Text integration is definitely coming. I'll post more details here soon.

 

I'm talking to the asset store team and I'll get back to you soon.

 

Hi,

I've updated the original gist to include possible implementations for both. In the case of duplicate line a different strategy is required because Unity already owns the key binding and actually dispatches it as a command named not surprisingly "Duplicate"

Code (csharp):

1.  
2. import Livity.Collections
3. import Livity.Composition
4. import Livity.Text.Data
5. import Livity.Text.UI.Commands
6. import Livity.Text.UI.Editor
7. import UnityEngine
8.  
9. [Export(IKeyboardModeProvider)]
10. class CustomKeyboardModeProvider(IKeyboardModeProvider):
11.     Name:
12.         get: "Mine"
13.    
14.     def KeyboardModeFor(editor as ITextEditor):
15.         return KeyBindings() {
16.             "&up": editor.Operations.TransposeLineUp,
17.             "&down": editor.Operations.TransposeLineDown,
18.             "^s": { editor.Operations.ExecuteCommand("Livity:Save") },
19.             "^r": { editor.Operations.ExecuteCommand("Livity:Save:Refresh") },
20.             "f1": { Help(editor) }
21.         }
22.        
23.     def Help(editor as ITextEditor):
24.         word = editor.DocumentNavigator.CurrentWord.Text.Trim()
25.         if string.IsNullOrEmpty(word): return
26.         Application.OpenURL("http://docs.unity3d.com/Documentation/ScriptReference/30_search.html?q=$word")
27.        
28. [Export(ICommand)]
29. class Duplicate(DocumentCommand, INamed):
30.     Name:
31.         get: "Duplicate"
32.  
33.     override def ExecuteCommandOn(doc as ITextDocument):
34.         line as ITextSnapshotLine = doc.CurrentLine()
35.         newText = (line.Text if line.IsTerminated else "\n" + line.Text)
36.         doc.Insert(line.End, newText + "\n")
37.         doc.Caret.MoveDown(1)
38.  
39.  

Just keep in mind that I'll include Duplicate in the next update as a native command in which case you'll probably want to delete yours unless you want a quadruplicate effect

 

Well, in my option the goal here would be to make Livity editing features to be compare to Sublime (which, yes is perfect even missing intelisense) and not the opposite, meaning to disregard Livity IDE. At least that's my wish.
Bringing Livity editor closer to sublime's inteligent highlighting and coloring + sublime key editing features will be great. I guess that's the reason why poeple prefer Sublime over using Livity IDE as of now. Elaborate

PS:Im a Sublime fanatic myself
