Match statement with arrays of strings not working!

CommonTiger

Hello! I'm working on a save system for a large game. Here is an example of what I'm trying to do:

Grab the correct information from a node in a group:

extends Node2D

func get_object_information(target:Node2D) -> Dictionary:
	var groups:Array = target.get_groups() 
	
	var objData:Dictionary = {
		"Filename":target.filename,
		"PosX":target.position.x,
		"Pos":target.position.y,
		"RotationD":target.rotation_degrees,
		
	}

	match groups:
		
		["Building"]:
			objData["BuildingName"] = target.buildingName as String

		["Person"]:
			objData["PersonState"] = target.state as int

	return objData

It worked with if else statements, but the code got messy real fast. But with match statements, it does not work.

I may be wrong, but doesn't that need to be in a for loop? i.e your matching on each element in the 'groups' array: for ele in groups: match ele:

Match takes an expression, not an array. It's not a loop.

I see what you are trying to do though. However, the array that is returned from get_groups() can have any number of items. Your code would work if each item had only one string value that matched you selection. But if that item had 2 strings in it, then it wouldn't work.
