I'm making a puzzle game, where you connect water pipes into loops and they queue_free() when they're in a loop.
Clicking a pipe rotates it by 90 degrees, as shown in the above picture's green arrows. The main scene contains the pipe Area2D scenes ( pipestraight, pipebend, pipetshape, and a pipecross). The pipes all have empty and full (of water) Sprite2Ds that trigger when each pipe's end touches the next pipe's Area2D and its respective CollisionPolygon2D.
The idea: the bigger the loop of full pipes, the loop queue_free()s and the more points you get.
My problem is having Godot understand that I have a loop. I know I need to use arrays somehow to combine them into a loop, but I'm not sure how.
I have everything on lockdown until the _on_area_entered_ function. Below is my code:
extends Area2D
@onready var empty: Sprite2D = $Empty
@onready var full: Sprite2D = $Full
@onready var connected_pipes = []
func _ready() -> void:
area_entered.connect(_on_area_entered)
area_exited.connect(_on_area_exited)
func _process(_delta: float) -> void:
if has_overlapping_areas():
fill_pipe()
else:
empty_pipe()
func _input(event):
if event is InputEventMouseButton and event.pressed and event.button_index == MOUSE_BUTTON_LEFT:
print(connected_pipes)
if empty.get_rect().has_point(to_local(event.position)):
rotate_pipe()
func rotate_pipe():
rotation_degrees += 90
func _on_area_entered(area: Area2D) -> void:
if area not in connected_pipes:
var adjacent_pipes = get_overlapping_areas()
if area not in connected_pipes:
connected_pipes.append(area)
for adjacent_pipe in adjacent_pipes:
if adjacent_pipe not in connected_pipes:
connected_pipes.append(adjacent_pipes)
func _on_area_exited(area: Area2D) -> void:
if area in connected_pipes:
connected_pipes.erase(area)
func fill_pipe():
empty.hide()
full.show()
func empty_pipe():
empty.show()
full.hide()Any help is appreciated!
