Custom objects as parameters not working?

[hmrrrrr]

Calling an exported function that uses a custom object as a parameter (like in this example) doesn't seem to work:

package main

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

type CustomObject struct {
	classdb.Extension[CustomObject, Object.Instance]
	Num int
}

type CustomNode struct {
	classdb.Extension[CustomNode, Node2D.Instance]
	OtherNum int
}

func (node *CustomNode) ApplyCustomObject(obj *CustomObject) {
	node.OtherNum = obj.Num
}

func main() {
	defer startup.Scene()

	classdb.Register[CustomNode]()
	classdb.Register[CustomObject]()
}

The following GDScript then causes a panic at runtime:

func _ready() -> void:
	var obj := CustomObject.new()
	obj.num = 57
	
	custom_node.apply_custom_object(obj)

panic: cannot convert [1]gd.Object to struct main.CustomObject

Not sure if this is missing functionality or if there's an intended way of doing this - maybe the function could accept an Object.Instance and cast it some other way??

Hmm, by design that should just work as you've expected it to. I'll have a look at this and let you know when it's working. Thank you for providing a complete example!

@hmrrrrr have added a test for this which is now passing, so this should work now!
