this should be an easy array append but somehow I cant make it work
so in CardManager, I have this simple append that add card to the array (the card should have values like card name, number etc)
$"../GameManager".card_on_player_board.append(card_being_dragged)
but in GameManager when I tried to use the array, it has the card object but when I check the value in it, it comes out null?
what Im doing wrong here?
let me know if you need more line of code.
let me send the .gd here
cerulean terrace
func finish_drag():
card_being_dragged.scale = Vector2(CARD_ENLARGE,CARD_ENLARGE)
var card_slot_found = raycast_check_for_card_slot()
if !played_card_this_turn:
if card_slot_found and not card_slot_found.card_in_slot:
# Card dropped in empty card slot
card_being_dragged.scale = Vector2(CARD_REDUCE,CARD_REDUCE)
player_hand_reference.remove_card_from_hand(card_being_dragged)
card_being_dragged.card_slot_is_in = card_slot_found
card_being_dragged.position = card_slot_found.position
card_being_dragged.get_node("Area2D/CollisionShape2D").disabled = true
card_slot_found.card_in_slot = true
$"../GameManager".card_on_player_board.append(card_being_dragged)
played_card_this_turn = true
card_being_dragged = null
return
player_hand_reference.add_card_to_hand(card_being_dragged, DEFAULT_CARD_MOVE_SPEED)
card_being_dragged = null
so in gamemanager
func play_the_best_card():
if card_on_player_board.size() != 0:
var opponent_hand = $"../OpponentHand".opponent_hand
var card_on_the_board = card_on_player_board.duplicate()
var player_card_with_the_highest_point = card_on_the_board[0]
for card in card_on_player_board:
**if card.value > player_card_with_the_highest_point.value:**
player_card_with_the_highest_point = card
if opponent_hand.size() == 0:
return
var random_empty_cardslot = empty_cardslot[0]
empty_cardslot.erase(empty_cardslot)

which one is line 69
cerulean terrace
which one is line 69
the one with **
rustic breach
i see
go ahead and print out what card is first.
and print out what player_card_with_the_highest_point is
there's probably something funky going on with the $... syntax
(it breaks. so easily.)
cerulean terrace
go ahead and print out what `card` is first.
func play_the_best_card():
if card_on_player_board.size() != 0:
var opponent_hand = $"../OpponentHand".opponent_hand
var card_on_the_board = card_on_player_board.duplicate()
var player_card_with_the_highest_point = card_on_the_board[0]
for card in card_on_player_board:
print(card)
if card.value > player_card_with_the_highest_point.value:
player_card_with_the_highest_point = card
if opponent_hand.size() == 0:
return
var random_empty_cardslot = empty_cardslot[0]
empty_cardslot.erase(empty_cardslot)
so I do this
Card:<Node2D#32883344776>
got this
rustic breach
im assuming you have some kind of Card class
(this is why you wanna use static typing btw, so your types are clear).
card is something. i have no clue what, but I'm assuming a Card.
so what's value on the Card class.
@cerulean terrace ?
rustic breach
well your card is some type of object. I want to know the type of that object. I'm assuming it's a Card.
cerulean terrace
extends Node2D
signal hovered
signal hovered_off
var position_in_hand
var card_slot_is_in
var value
func _ready() -> void:
#All cards must be a child of CardRanger or this will error.
get_parent().connect_card_signal(self)
func _on_area_2d_mouse_entered() -> void:
emit_signal("hovered",self)
func _on_area_2d_mouse_exited() -> void:
emit_signal("hovered_off",self)
ok this is on my card
how the card it to the value
rustic breach
oh god even the value isn't typed
cerulean terrace
like I said, im seeing a tutorial, and use my learn programming to make sense of the code
rustic breach
i get that yeah
cerulean terrace
sorry if this look so much worse
rustic breach
it's not your fault, the tutorial is just writing some shitty ass code.
anyway is the value supposed to be a number or something?
cerulean terrace
yes
rustic breach
okay so we can annotate it as being a number by, say, doing var value: int or var value: float
which lets us (and you!) know what type the value has.
but that's besides the point for now.
rustic breach
it seems as if your value is never set to an actual value. so Godot thinks it's null.
(it also doesn't know to set it to an 0 rather than a null, because it has no idea that value is supposed to be a number).
cerulean terrace
wait
your right...
as soon I put int
the code run
huh but need more cleaning
thanks you
let me see if I can make this code work as I intended before writing this as solved
