Script simplified to illustrate problem of state at _init:

extends Resource

export(int) var i

func _init():
    var x = 0 + i

x is always 0 even if i is set to a value other than 0 in the Inspector pane of the editor for that resource. How do we get the set value during initialization of the resource?

Could you use _ready instead?

This is a resource (extends Resource), not a node.

Ha yes, did not saw that. It seems there is no hook for when the resource is loaded. What I would do is to define a setter for my export.

Would a setter function for the exported property be called if the value is set in the Inspector?

Yes it should, but only if you declare the script as a tool.

This could work. I think the suggestion here is doing the work in a node script setget set or property set intercept function. Ideally, this would be part of the code of the Resource, not of a node script, but I’m going to accept this as the best solution we know.
