I've tried adding the Rotate.ts script as per the documentation but I am not getting any Monobehavior script in Needle/Components.codegen

I get two Unity console messages after saving my Rotate.ts script:

/Assets/../Library/Needle/CodeGen/Types.json
SourceFiles: -1 

Run codegen for Rotate.ts at ...../Needle/CollaborativeSandbox/src/scripts/Rotate.ts```

I've tried enabling/disabling the Code Generator Component in Unity

mystic axle Dec 14, 2022, 5:42 PM

#

Are you on windows? What is your project path? The run codegen path in the log looks suspicious (starting with ...../Needle)

raven cedar Dec 14, 2022, 5:43 PM

#

Hi. I'm on Mac. I've just edited out the rest of the file path that has my name and other bits in it

mystic axle Dec 14, 2022, 5:45 PM

#

Ah I see. Does the path look correct? Maybe replace it with xxxx next time 🙂 makes it less confusing^^

But SourceFiles: -1 also looks wrong

#

Does the log say anything? The console log should also contain a path where the compiler produces a log file - maybe it has some info on why it didnt output a script

raven cedar Dec 14, 2022, 5:47 PM

Haha I see the confusion now. Yes the path is correct

mystic axle Dec 14, 2022, 5:47 PM

#

I've also asked for the path because we sometimes had issues with special characters in paths (e.g. paths containing ( )

raven cedar Dec 14, 2022, 5:48 PM

#

Ok, let me just copy and paste the full log

mystic axle Dec 14, 2022, 5:48 PM

Could you also try creating a npmdef and copy paste your script there?

Did it also write the file?

raven cedar Dec 14, 2022, 6:04 PM

#

It did!

mystic axle Dec 14, 2022, 6:04 PM

#

Ok great - so something is not working with sending the command to the compiler 🤔 maybe

#

if you edit the ts file and Unity tried to re-generate it - does it work? Or not?

#

E.g. add a new field or remove it 🙂

#

or rename the class

raven cedar Dec 14, 2022, 6:06 PM

#

Yes that works

#

I've also tried adding a new script but it doesn't generate

mystic axle Dec 14, 2022, 6:09 PM

#

🤔 ok that's strange. did you also try with the npmdef?

raven cedar Dec 14, 2022, 6:10 PM

#

raven cedar I've also tried adding a new script but it doesn't generate

i.e. TestScript.ts doesn't generate

raven cedar Dec 14, 2022, 6:10 PM

#

mystic axle 🤔 ok that's strange. did you also try with the npmdef?

I'll try that, just reading the reference for that to get my head around

mystic axle Dec 14, 2022, 6:10 PM

#

raven cedar i.e. TestScript.ts doesn't generate

It also contains a class (e.g. export class MyClass extends Behaviour ? )

raven cedar Dec 14, 2022, 6:11 PM

#

mystic axle It also contains a class (e.g. ``export class MyClass extends Behaviour`` ? )

Yeah exact same contents as the original Rotate.ts

mystic axle Dec 14, 2022, 6:12 PM

#

Ok - of course the classname shouldnt be the same 😅

raven cedar Dec 14, 2022, 6:22 PM

#

mystic axle Ok - of course the classname shouldnt be the same 😅

of course TrippyBlob

#

No luck with using npmdef :I

mystic axle Dec 14, 2022, 6:25 PM

#

Ok good 🙂

#

I mean then its at least consistent 🙂

raven cedar Dec 14, 2022, 6:26 PM

#

Oh ok - fair enough

reef charm Dec 26, 2022, 1:32 PM

#

also have this issue on Windows and Mac, what can i do?

#

@mystic axle i tried your command and after this c# script generated
but new scripts dont generate

mystic axle Dec 26, 2022, 1:44 PM

#

What is the path of your project? Can you share the compiler log file too? You can also use Help/Needle Engine/Collect logs and PM me the zip

mystic axle Dec 26, 2022, 2:01 PM

#

Which node version are you using?

v16.14.0

#

📎 Bugreport-Main-221226.zip

#

also i switch from 2022 version to 2021.3 as recommend on requirements

reef charm Dec 26, 2022, 2:22 PM

#

also wanted to mention that
my rotate.cs

// NEEDLE_CODEGEN_START
// auto generated code - do not edit directly

#pragma warning disable

namespace Needle.Typescript.GeneratedComponents
{
    public partial class Rotate : UnityEngine.MonoBehaviour
    {
        public float @speed = 1f;
        public float @money = 3f;
        public void start(){}
        public void update(){}
    }
}

// NEEDLE_CODEGEN_END

when rotate.ts is

import { Behaviour, serializable } from "@needle-tools/engine";

export class Rotate extends Behaviour
{
    @serializable()
    speed : number = 1;
    
    money: number = 3;

    start(){
        // logging this is useful for debugging in the browser. 
        // You can open the developer console (F12) to see what data your component contains
        console.log(this);
    }

    // update will be called every frame
    update(){
        this.gameObject.rotateY(this.context.time.deltaTime * 1);
    }
}

it's quite strange that update is empty

#

it's after when i run command manually from terminal

#

also thanks for needle
it's quite brilliant idea to bring unity to three js because wasm and unity webgl too slow

but i can't use engine at all because custom scripting doesnt work🥲

mystic axle Dec 26, 2022, 4:43 PM

#

It does work, you can use needle engine and the exporter, just auto compiling seems to have an issue from unity for some of you. I tried this on osx after it was reported but couldnt reproduce (the compiler worked as expected)

Im currently on holiday and will be back on the 30th to try to figure out why. You can manually create a c# component or invoke the script command manually that is logged in the console. Exporting components does still work.

Also all methods in csharp will always be empty because we don't build the full csharp code, only components to hold the data for you to setup in unity and export (you can still implement them in c# if you want to of course)

#

You can read about it at https://docs.needle.tools/scripting

#

oh, i see
everything working, okey
it's quite interesting why auto exporter doenst work in mac os and windows (two different machines)
thanks for reply, now i can use command btw

mystic axle Dec 26, 2022, 5:11 PM

#

By auto exporter you mean the compilation of js to csharp mock right?

mystic axle Dec 26, 2022, 5:11 PM

#

reef charm

reef charm Dec 26, 2022, 7:41 PM

#

yeah, i can generate c# files only with compile command, auto save doesnt work

mystic axle Dec 30, 2022, 2:09 PM

#

Hey guys, could you try updating to the latest release and then try running the same command using the command tester window I added? You can open it via this menu item

#

and then enter the command you run manually with the correct paths like this and tell me what it says 🙂 (you can try both Run in Unity and Run External)

#

You can also try enabling "Debug" on the component and then re-save one of the scripts

ashen widget Jan 1, 2023, 4:24 PM

#

I'm also having problems with the generator. I tried running the command in the command tester and I got zsh:1: command not found: node. Could it be related to the node path issue reported here? #📍-needle-engine message

mystic axle Jan 1, 2023, 6:34 PM

#

Yes that would be that issue. But does generating projects work? Do you use nvm?

mystic axle Jan 2, 2023, 9:46 AM

#

@reef charm any chance you could try the above too once more? Im currently trying to reproduce / figure out why its not working for you guys.

reef charm Jan 2, 2023, 9:47 AM

#

yeah, i will try later today, thanks

mystic axle Jan 2, 2023, 9:47 AM

#

thank you

#

@tulip plume sorry to ping you - you also had problems with the compiler not working or was it just the error with the wrong path check that caused problems?

#

I just realized that internally it doesnt handle "node" commands the same way it does "npm" commands, so maybe that is the problem here

tulip plume Jan 2, 2023, 10:31 AM

#

Hi @mystic axle ... I'm fairly certain that it was just the error with the wrong path check that was the issue, in my case.

Just shout if there's anything you'd like me to specifically check out and/or test 👍

mystic axle Jan 2, 2023, 10:35 AM

#

tulip plume Hi <@272528485732450305> ... I'm fairly certain that it was just the error with ...

Yes 🙂 could you try opening the command tester window (via Needle Engine/Internal/Command Tester) and run node --version and let me know what it prints? (use the run in Unity button).

And how did you install node? Are you using brew, nvm or anything else?

tulip plume Jan 2, 2023, 10:44 AM

#

I'll give that a go right now, and let you know asap 👍

Re: node installation... I adhered to the instructions provided via the 'Get Started' page. I can't remember precisely what advice was given there and I'm afraid I can't copy and paste the walkthrough as I've just noticed that the 'see details' link I originally followed no longer works.

2.55.1 is latest 🙂

How did you install node? Nvm or also using the installer?

#

What does which node print when you run it in the terminal?

#

I might have a fix - will publish in a second

reef charm Jan 2, 2023, 11:09 AM

#

mystic axle How did you install node? Nvm or also using the installer?

i dont remember, maybe with brew (i only recently update node for some other work projects)

#

/Users/ivan/.nvm/versions/node/v16.14.0/bin/node

#

i have installed node before trying needle, because using it for vue, vite and other js projects

mystic axle Jan 2, 2023, 11:11 AM

#

Ah nvm ok, thanks.

#

Could you update to 2.55.2-pre and let me know if that helps?

Generating projects works and so does the server. I installed nvm to get around the previous path bug

mystic axle Jan 2, 2023, 1:35 PM

#

The previous path bug should also be fixed 🙂 but thanks, good to hear

I ran in to this same issue on exporter version 2.58.1-pre. Fix in my case was to update my project path to include no spaces.
