Hey guys,
for a school exam i have to create a candy crush clone and everything work fine except ohne thing. i can swap my pieces to the left and also to the right but i can’t swap it down or up. does anyone knows why?
here is my code:
extends Node2D
export(int) var width
export(int) var height
export(int) var x_start
export(int) var y_start
export(int) var offset
#piece array
var possible_pieces = [
preload("res://orange_piece.tscn"),
preload("res://blue_piece.tscn"),
preload("res://pink_piece.tscn"),
preload("res://red_piece.tscn"),
preload("res://green_piece.tscn"),
preload("res://lila_piece.tscn"),
]
#current piece in scene
var all_pieces = []
#touch variables
var first_touch = Vector2(0,0)
var final_touch = Vector2(0,0)
var controlling = false
func _ready():
randomize()
all_pieces = make_2d_array()
spawn_pieces()
func make_2d_array():
var array = []
for i in width:
array.append([])
for j in height:
array[i].append(null)
return array
func spawn_pieces():
for i in width:
for j in height:
#choose a random number and store it
var rand = floor(rand_range(0, possible_pieces.size()))
var piece = possible_pieces[rand].instance()
var loops = 0
while(match_at(i, j, piece.color) && loops < 100):
rand = floor(rand_range(0, possible_pieces.size()))
loops += 1
piece = possible_pieces[rand].instance()
#instance that piece from the array
add_child(piece)
piece.position = grid_to_pixel(i, j)
all_pieces[i][j] = piece
func match_at(i, j, color):
if i > 1:
if all_pieces[i - 1][j] != null && all_pieces[i - 2][j] != null:
if all_pieces[i - 1][j].color == color && all_pieces[i - 2][j].color == color:
return true
if j > 1:
if all_pieces[i][j - 1] != null && all_pieces[i][j - 2] != null:
if all_pieces[i][j - 1].color == color && all_pieces[i][j - 2].color == color:
return true
pass
func grid_to_pixel(column, row):
var new_x = x_start + offset * column
var new_y = y_start + -offset * row
return Vector2(new_x, new_y)
func pixel_to_grid(pixel_x, pixel_y):
var new_x = round((pixel_x - x_start) / offset)
var new_y = round((pixel_y - y_start) / -offset)
return Vector2(new_x, new_y)
pass
func is_in_grid(column, row):
if column >= 0 && column < width:
if row >= 0 && row < height:
return true
return false
func touch_input():
if Input.is_action_just_pressed("ui_touch"):
first_touch = get_global_mouse_position()
var grid_position = pixel_to_grid(first_touch.x, first_touch.y)
if is_in_grid(grid_position.x, grid_position.y):
controlling = true
#print("OK")
#else:
# print("NOT OK")
if Input.is_action_just_released("ui_touch"):
final_touch = get_global_mouse_position()
var grid_position = pixel_to_grid(final_touch.x, final_touch.y)
if is_in_grid(grid_position.x, grid_position.y) && controlling:
touch_difference(pixel_to_grid(first_touch.x, first_touch.y), grid_position)
func swap_pieces(column, row, direction):
var first_piece = all_pieces[column][row];
var other_piece = all_pieces[column + direction.x][row + direction.y];
all_pieces[column][row] = other_piece;
all_pieces[column + direction.x][row + direction.y] = first_piece;
first_piece.position = grid_to_pixel(column + direction.x, row + direction.y);
other_piece.position = grid_to_pixel(column, row);
func touch_difference(grid_1, grid_2):
var difference = grid_2 - grid_1
if abs(difference.x) > abs(difference.y):
if difference.x > 0:
swap_pieces(grid_1.x, grid_1.y, Vector2(1,0))
elif difference.x < 0:
swap_pieces(grid_1.x, grid_1.y, Vector2(-1,0))
elif abs(difference.y) > abs(difference.x):
if difference.y > 0:
swap_pieces(grid_1.x, grid_1.y, Vector2(0,1))
elif difference.y < 0:
swap_pieces(grid_1.x, grid_1.y, Vector2(0,-1))
func _process(delta):
touch_input()
i also get an error when i want to debug the game:
W 0:00:02.212 The argument 'delta' is never used in the function '_process'. If this is intended, prefix it with an underscore: '_delta'
<C++ Error> UNUSED_ARGUMENT

to create the game i’m using the tutorial of mister traft creates and i’m at episode 7 (click here to see the vid)
