Godot Version
Godot 4.3 Stable
Question
This is severely confusing the hell out of me. I’m a fluent developer of Python, but not with Godot Script yet. I’ve developed for over 5 years in Python, but was limited to what I wanted to achieve, so have been trying to port my game in Python, over to Godot. I followed a tutorial, and have a working game, and tried to model my class/script based on other code that works, and my code does not work.
I’m getting an error of:
" Invalid call. Nonexistent function ‘generate_item’ in base ‘Nil’ "
Based on this error, I’m assuming the base class is not being initialized/instantiated and thus why it cannot find the function. However, I’m not sure what I’m doing wrong.
So I’ve tested the code within the main script first, and the code works properly, but I don’t want to bloat the main script with a ton of code, so I wanted to send the data to a large code block in another script file, to keep things clean and orderly.
In the main script I have this up at the top:
@onready var item_gen: GeneratorOfItems
The script it is in, is called generator_items.gd
This is the code in that script:
class_name GeneratorOfItems
extends Node
var _rng := RandomNumberGenerator.new()
func _ready() → void:
_rng.randomize()
print(“it exists”)
func generate_item(new_entity) → Entity:
var weapon_names: Array[String] = [‘Blade’, ‘Shortsword’, ‘Scimatar’, ‘Rapier’]
var icons: Array[Vector2i] = [Vector2i(512,112), Vector2i(528,112), Vector2i(544,112), Vector2i(560,112), Vector2i(576,112)]
var chosen_name: String = weapon_names[_rng.randi_range(0, len(weapon_names) - 1)]
var chosen_icon: Vector2i = icons[_rng.randi_range(0, len(icons) - 1)]
new_entity.texture.region = Rect2(chosen_icon, Vector2i(16,16))
new_entity.entity_name = chosen_name
print("Success")
return new_entity
Called every frame. ‘delta’ is the elapsed time since the previous frame.
func _process(delta: float) → void:
pass
Now it should be noted the _ready function doesn’t get called, as I never see “it exists” in the log and then it errors out when it tries to call generate_item.
I’ve tried every permutation I can think of to try to fix this issue, but I don’t understand Godot Script enough to figure it out on my own. I tried googling the issue, and none of the answers I found address my question.
