How do I use classdb.Tool?

[nii236]

I want to have the same effect as @tool from gdscript. Basically I have written a tool that I want to run in the editor.

I've uploaded a minimal reproduction here: https://github.com/nii236/gd_mre

Currently, the sprite only rotates when the game is running, but in the editor it does not run at all.

Here's the full code from the MRE:

package main

import (
	"fmt"
	"math"

	"graphics.gd/classdb"
	"graphics.gd/classdb/Sprite2D"
	"graphics.gd/startup"
	"graphics.gd/variant/Float"
)

type RotateSprite struct {
	classdb.Extension[RotateSprite, Sprite2D.Instance]
	classdb.Tool
}

func (r *RotateSprite) Ready() {
	fmt.Println("RotateSprite Ready")
}
func (r *RotateSprite) Process(delta Float.X) {
	current := r.Super().AsNode2D().Rotation()
	r.Super().AsNode2D().SetRotation(current + Float.X(math.Pi*delta))
}

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

This is a bug/regression, fixed in d191cb2, your example now works as expected.

Awesome! Works now.
