C-sharp component not being generated

🌵 Needle Engine
1

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

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

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

by user 285903863339548673

4

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

But SourceFiles: -1 also looks wrong

5

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

6

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

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

8

Ok, let me just copy and paste the full log

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

No file named component-compiler.log

Can you try opening a terminal and run this command:

node component-compiler.js "/Users/durril/Documents/Unity Projects/Needle Engine Test/Assets/Needle/Components.codegen" "/Users/durril/Documents/Unity Projects/Needle Engine Test/Needle/CollaborativeSandbox/src/scripts/Rotate.ts"
in this directory:
/Users/durril/Documents/Unity Projects/Needle Engine Test/Library/PackageCache/com.needle.engine@2.53.1-pre.1/package~/node_modules/@needle-tools/needle-component-compiler/src

Did it also write the file?

It did!

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