[Bug]: No way to enable the plugin about godot_debug_draw_3d

[DmitriySalnikov]

It's not really a plugin... EditorPlugins in GDExtension are not working properly at the moment. Therefore, this addon is embedded in the editor using a hacks.
To check whether it is connected or not, you can simply search for DebugDraw in the built-in documentation. There should be a DebugDraw class (and several other classes) and a singleton.
Didn't you restart the editor after installation? Were there any errors in the console at startup?

I just wanted to enable the debug lines in the Editor using Engine.is_editor_hint(), not in-game, which are already working.

Do you use the @tool annotation in your script? (as for example in examples_dd3d/addon_icon.gd)

[DmitriySalnikov]

Have you solved this issue?
I don't even understand the essence of the issue, since all my examples already work in the editor and in a running project.

Cannot reproduce:

Steps:

1. make empty project
2. install your add-on
3. restart the editor
4. play the demo scene

What I got is an DebugDrawConfig2D not declared on line 15.

Sorry, but it really does not work right now in Godot4. I don't know what you did differently so it works for you. 🤔

4.0.2
Just downloaded from AssetLib
Only the C# files have been deleted

Upd:
4.0

Upd:
4.0.2 Ubuntu

Just downloaded from AssetLib

Did you do something else besides the steps I explained above? Is there ... idk ... some setting or ... I'm confused ...

[DmitriySalnikov]

For the ubuntu test, I even had to download the engine, because the system was almost empty.. And I just created the project and immediately entered AssetLib.
Can you show the console output (which runs through a separate exe)?

It seems to me that I have guessed what the problem is...
After viewing the contents of the console, try installing vcredist
If that's the problem, then I need to figure out how to get rid of this dependency. 😫

Oops I forgot tho include the console out, how unprofesional :P

[DmitriySalnikov]

Probably the problem is that you are using an operating system with outdated libstdc++ libraries. For example, my library is compiled on Ubuntu 22.04.2, and you have Ubuntu 20.04.6 installed.

---

Oh, you're using SteamOS. I have no idea how to fix the problem. I've already spent 6 hours today trying to install another arch-based OS, and I'm already sick of it...

[DmitriySalnikov]

@venilark what about your problem?

[betalars]

Probably the problem is that you are using an operating system with outdated libstdc++ libraries.

okay will see where I can get libstdc++ 6 from then ...

[betalars]

Okay sorry, but this is not a practical option. I can technically create an environment where there are user level links for this library, but I'm afraid most users of arch derivates or nixos (in my case) won't be able to use your add-on then.

Can take some time later to think of a workaround, but for now I'll just be using ray casts... :P

[DmitriySalnikov]

to think of a workaround

I haven't tested it yet, but it might be possible to statically link everything I need directly to the library so that it doesn't depend on other libraries. This is also relevant for vcredist on Windows..

[betalars]

Okay, yeah I hope this will be a good solution for compatibility.

And to summarize the actual issue:
Nixos does a lot of fancy things when it comes to providing libraries, and we're on a much newer version than Ubuntu, but your AddOn could simply not find it from it's scope.

So I'm using steam-run godot when launching godot to provide it with an environment that it will be happy with. It's kind of overkill, but it should resolve most dependency issues of these sorts.
