I have a cyclic reference in my Hexagonal Position class. How do I deal with this?

AnthropomorphicBeing

What I want to do is have a class that represents a position on a hexagonal grid (HexaPosition). Basically it has an x and y. One method transforms them and returns them in a Vector2 representing the position on a imaginary hexagonal grid. And another method will do the same, but the Vector2 will have the positions they have in the real world according to the size of the hexagon (a property of this class). Getting to the point... I want a method that will return the positions surrounding any given coordinate. I want this list of coordinates to be objects instanced from my HexaPosition class. Godot complains of a cyclic reference. Is there any way to do this avoiding the circular reference? Thanks for your attention.

I remember I had this issue once and worked around it, but I do not remember that the exact solution was. I think what I did is that I didn't directly reference the class or use class_name in one of the two files, avoiding the cyclic reference, and instead using a constant to tell if what I had was the class I wanted. I think I had a constant like const IS_NAME_HERE = true as the constant in the object (renamed so it reflects the actual object), and then used code like if ("IS_NAME_HERE" in variable): to tell if the variable I had was the class I wanted. The downside with this method is that the Godot editor will not autocomplete variable or function names, but it removes the cyclic reference issue (if I am remembering correctly).

I don't get it. What was inside the if?

Something like this, for example:

First class (we'll say its for a potion, for this example):

extends Node
const IS_POTION = true

func do_potion():
	print ("Potion stuff!")

Second class:

extends Node
func _ready():
	var potion_node = get_node("Potion")
	# make sure we are working with the script above
	if ("IS_POTION" in potion_node):
		# we know we are working with the above script!
		potion_node.do_potion()
		# While autocomplete will not show it, we can
		# access all of the properties and functions with
		# confidence, as long as "IS_POTION" is only defined
		# in just the one script (and whatever extends it).

Hopefully the examples above illustrate what I was meaning! If not, let me know and I'll see if I can make a more illustrative example. (Sorry on the delay in responding!)

That works. Thanks a lot
