Can not find registered node in Godot editor

[nii236]

I've created a minimally reproducible example here: https://github.com/nii236/gd_mre

I feel like this is more of a "I don't know how to use this library", but maybe it'll help others to ask in the open.

I've created a type Example struct but I can not find it in the editor after running gd.

I'm using a Macbook Pro M1.

package main

import (
	"graphics.gd/classdb"
	"graphics.gd/classdb/Node2D"
	"graphics.gd/startup"
)

type Example struct {
	classdb.Extension[Example, Node2D.Instance] `gd:"Example"`
}

func main() {
	startup.Loader()
	classdb.Register[Example]()
	startup.Engine()
}

Have you tried renaming the type, to something other than `Example? I think this may be somewhat reserved in the engine.

yeah changed to NXRExample (see commit) and same issue

Does it happen when you try my repo too?

@nii236 thanks for the reproduction project, I've taken a closer look, the reason why this doesn't work as expected, is that classdb.Register[Example]() is being called after startup.Loader(), anything after startup.Loader() is not executed when the project launches within the editor, only when the project is actually running. You can verify this by adding a fmt.Println after startup.Loader() and launching the editor with gd.

We may want to reword this function and/or improve the documentation of the startup function(s). Essentially startup.Loader is meant to mean something like (it was briefly called startup.Wait but this was also somewhat ambiguous, in respect to what you are actually waiting for):

We have linked to the engine, all functions/singletons are now available for use. This is the final initialization phase before you surrender control back to the engine's default main loop startup.Engine. This function does not return if running in the editor.

Let me know if you have any suggestions/feedback around this. There isn't an editor-specific equivalent to startup.Loader yet, which may be useful for initializing editor-specific plugins.

It works! Thanks.

Easiest fix would be to note in the function comment for startup.Loader() that all classdb.Register calls needs to be called before it.

@nii236 cheers have updated the function with a comment.
