Question
here is a quick over view of what’s happening . i defined an inventory class extending recourse which has an array of another class called inventory slot . each slot has to properties item and quantity . item is an other defined class which holds onto texture , name and max slot quantity(to define how many of each item could be contained in one slot)
class_name Item
@export var name : String
@export var texture : Texture2D
@export var max_quantity : int
class_name InventorySlot
@export var item : Item
@export var quantity : int
var empty_space : int :
get():
return item.max_quantity - quantity
func is_full() -> bool:
return quantity < item.max_quantity
func is_empty() -> bool:
return quantity<=0 or !is_instance_valid(item)
func is_item(new_item:Item) -> bool:
return new_item == item
class_name Inventory
@export var slots : Array[InventorySlot]
@export var weapons : Array[InventorySlot]
i also have collectable class which an other class name collectable_item inherits from it , it basicly is an area2d which calls collect() on what ever coms in it and passes it self to it . in this case is more like player.collect(collectable)
class_name Collectable
func _on_body_entered(body):
if body is Player :
body.collect(self)
extends Collectable
class_name CollectableItem
@export var item : Item
@export var quantity : int
i made a inventory resource file in my project and assighned it to export variable of my player and gui .
here is player code:
extends CharacterBody2D
signal player_health_update(hp:float, max_hp:float)
@export var states : Status
@export var inventory : Inventory
@export var player_body_sprite : PlayerBodySprite
@export var can_move : bool = true
@export var is_rolling : bool = false
func _ready() -> void:
assert(is_instance_valid(states),"Player Stats Hasnt Been Set!")
assert(is_instance_valid(inventory),"Player inventory Hasnt Been Set!")
await owner.ready
self.player_health_update.emit(states.health,states.max_health)
# states.died.connect(on_player_died)
func _process(delta: float) -> void:
move()
func move():
if !can_move : return
var direction = Input.get_vector("left","right","up","down")
if direction == Vector2.ZERO :
player_body_sprite.idle()
return
player_body_sprite.walk()
velocity = states.move_speed * direction
move_and_slide()
func buff_effects():
pass
func _input(event: InputEvent) -> void:
if event.is_action_pressed("right"):
player_body_sprite.scale.x= abs(player_body_sprite.scale.x)
elif event.is_action_pressed("left"):
player_body_sprite.scale.x= -1*abs(player_body_sprite.scale.x)
func hurt(attack : Attack):
states.health -= attack.damage
player_health_update.emit(states.health,states.max_health)
func collect(collectable : Collectable):
if collectable is CollectableXp:
pass
elif collectable is CollectableItem:
var collected_item := collectable as CollectableItem
for i in inventory.slots.size() :
if collected_item.quantity <= 0 : break
print("collected : "+str(collected_item.quantity)+collected_item.name)
if inventory.slots[i].is_item(collectable.item):
while inventory.slots[i].empty_space>0 and collected_item.quantity>0 :
collected_item.quantity-=1
inventory.slots[i].quantity+=1
print("added to existing")
elif inventory.slots[i].is_empty() :
print("slot is empty so:")
inventory.slots[i].item=collected_item.item
inventory.slots[i].quantity=0
print("slot item:"+inventory.slots[i].item.name)
print("slot quantity:"+str(inventory.slots[i].quantity))
while inventory.slots[i].empty_space>0 and collected_item.quantity>0 :
collected_item.quantity-=1
inventory.slots[i].quantity+=1
print("added as new")
print("slot item:"+inventory.slots[i].item.name)
print("slot quantity:"+str(inventory.slots[i].quantity))
else: continue
if collected_item.quantity<=0 :
print("item collected")
collected_item.queue_free()
func die()->void:
pass
Problem : it basically collects the fu*king item off the ground , and prints it , but GUI doesn’t show it and its not even GUIs fault the item is no where to be seen even in remote player properties after being picked !
