Godot

Edit: ah i was reading an old doc because the reddit comment I saw was 6 years old. The property is get_property_list()

I have a script that is a global it contains a bunch of dictionaries that describe items. I need a way to get a list of the different types.

Searching for solutions I found https://docs.godotengine.org/en/3.2/classes/class_script.html#class-script-method-get-script-property-list

but I cant seem to get it working. Godot says "Function "get_script_property_list()" not found in base self"

Example of the what im trying to get a list of

var tile_dict_grass = {
	"name": "grass",
	"source": 1,
	"atlas": Vector2i(1,0),
	"move_speed": 0.80,
	"path_cost": 2,
	"fertility": 1,
	"cleanliness": 1.5,
	"flammability": 0.60,
	"build_categories": "all",
	"solid": false
}
var tile_dict_rich_soil = {
	"name": "rich soil",
	"source": 1,
	"atlas": Vector2i(1,0),
	"move_speed": 0.80,
	"path_cost": 2,
	"fertility": 1.4,
	"cleanliness": -1.0,
	"flammability": 0.0,
	"build_categories": "all",
	"solid": false
}

How im trying to get it.

func get_tile_dict():
	var property_list = self.get_script_property_list()
	var tile_list = []
	for attr in dir(self):
		if attr.startswith('tile_dict'):
			value = getattr(self, attr)
			tile_list.append(value)
	return tile_list
