Question
I’m trying to manually code my signals in the “dodge the creeps” tutorial to make sure that I understand how they work, but when I press the start button nothing happens. I’ve read and reread the documentation and many tutorials, but I still don’t know what I’m doing wrong.
I’m trying to connect the ‘pressed’ signal from the start button to the ‘_on_start_button_pressed()’ function in hud.gd, and then connect hud.gd’s ‘start_game’ signal to
the ‘new_game()’ function in main.gd. I’ve included hud.gd and main.gd below. Sorry if I’ve omitted any necessary info.
extends CanvasLayer
signal start_game
func func_ready() -> void:
$startbutton.pressed.connect(_on_start_button_pressed)
$messagetimer.timeout.connect(_on_message_timer_timeout)
func show_message(text):
$message.text = text
$message.show()
$messagetimer.start()
func show_game_over():
show_message("Game Over")
await $messagetimer.timeout
$message.text = "Dodge the Creeps!"
$message.show()
await get_tree().create_timer(1.0).timeout
$startbutton.show()
func update_score(score):
$scorelabel.text = str(score)
func _on_start_button_pressed():
$startbutton.hide()
start_game.emit()
func _on_message_timer_timeout():
$message.hide()
main.gd:
extends Node
@export var mob_scene: PackedScene
var score
func game_over():
$scoretimer.stop()
$mobtimer.stop()
$hud.show_game_over()
func new_game():
score = 0
$Player.start($startposition.position)
$starttimer.start()
$hud.update_score(score)
$hud.show_message("Get Ready")
func _ready() -> void:
$Player.hit.connect(game_over)
$mobtimer.timeout.connect(_on_mob_timer_timeout)
$scoretimer.timeout.connect(_on_score_timer_timeout)
$starttimer.timeout.connect(_on_start_timer_timeout)
$hud.start_game.connect(new_game)
func _on_mob_timer_timeout():
var mob = mob_scene.instantiate()
var mob_spawn_location = $mobpath/mobspawnlocation
mob_spawn_location.progress_ratio = randf()
mob.position = mob_spawn_location.position
var direction = mob_spawn_location.rotation + PI / 2
direction += randf_range(-PI / 4, PI / 4)
mob.rotation = direction
var velocity = Vector2(randf_range(150.0, 250.0), 0.0)
mob.linear_velocity = velocity.rotated(direction)
add_child(mob)
func _on_score_timer_timeout():
score += 1
$hud.update_score(score)
func _on_start_timer_timeout():
$mobtimer.start()
$scoretimer.start()
