Hello
“Simply” put, I am creating an Array of my Stat resource class in my Stats resource class in the Godot editor. I am trying to build a dict on my Stats class for easy value referencing although it is not populating:
I have created Stats class, and Stat class, both extending Resource.
I am adding Stats to my BaseMob like so:
class_name BaseMob extends RigidBody2D
@export var stats: Stats
I want to reference stat values like this (again in my BaseMob):
func _ready():
normalized_speed = stats.speed / 100.0
Although the dictionary I am creating in my Stats class does not seem to be populated, nor gettable with my overridden _get function when add my mob to the scene.
My Stats array however has the single “speed” stat in as expected.
Stats class:
class_name Stats extends Resource
@export var stats: Array[Stat] = []
var stats_dict: Dictionary = {}
func _ready():
for stat in stats:
stats_dict[stat.name] = stat
func _get(name):
if stats_dict.has(name):
return stats_dict[name].value
else:
return null
func update(delta: float):
for stat in stats:
stat.update(delta)
func reset_stats():
for stat in stats:
stat.reset()
Stat class:
class_name Stat extends Resource
enum Type { SPEED, DAMAGE, HP, MAX_HP, XP, MAX_XP, MASS, SCALE, FREQUENCY, COOLDOWN, DURATION, PASSTHROUGH, RANGE, HOMING, KNOCKBACK }
enum Modifier { ADD, MULTIPLY }
@export var type: Type
@export var name: String
@export var base_value: float
@export var value: float
var temporary_modifiers = []
func _init(type: Type = Type.SPEED, name: String = "", base_value: float = 0.0, value: float = 0.0):
self.type = type
self.name = Type.keys()[type]
self.base_value = base_value
self.value = base_value
func upgrade_stat(modifier: Modifier, value: float):
match modifier:
Modifier.ADD:
self.value += value
Modifier.MULTIPLY:
self.value *= value
func downgrade_stat(modifier: Modifier, value: float):
match modifier:
Modifier.ADD:
self.value = max(0, self.value - value)
Modifier.MULTIPLY:
if value != 0:
self.value = max(0, self.value / value)
else:
self.value = 0
func reset_stat():
self.value = self.base_value
func add_temporary_modifier(modifier: Modifier, value: float, duration: float):
var temporary_modifier = {
"modifier": modifier,
"value": value,
"duration": duration,
"elapsed": 0
}
temporary_modifiers.append(temporary_modifier)
func update(delta: float):
var expired_modifiers = []
for temporary_modifier in temporary_modifiers:
temporary_modifier.elapsed += delta
if temporary_modifier.elapsed >= temporary_modifier.duration:
downgrade_stat(temporary_modifier.modifier, temporary_modifier.value)
expired_modifiers.append(temporary_modifier)
for expired_modifier in expired_modifiers:
temporary_modifiers.erase(expired_modifier)
