Restart on a Key

Part of the Game Rules section of Coddy's Godot journey. Lesson 15 of 29.

This line throws the scene away and loads it fresh from its file:

get_tree().reload_current_scene()

The new game starts with three lives, the player on the green square and Game Over hidden.

Main is paused too, so its _process never sees the key. Set Main's own process_mode to Node.PROCESS_MODE_ALWAYS. Its children inherit that, except the player. The scene sets the player to Pausable, so it still stops.

Reloading does not unpause the game. Set get_tree().paused = false before you reload, or the new game starts paused.

Challenge

Easy

Let the player press E to play again after Game Over:

In _ready(), set this node's process_mode to Node.PROCESS_MODE_ALWAYS.
In _process(), when lives is 0 and action was just pressed, unpause the game and reload the scene.

Try it yourself

extends Node2D

var lives = 3

func _ready():
	$HUD/Lives.text = "Lives: %d" % lives
	$Player.hurt.connect(_on_player_hurt)
	$Blink.timeout.connect(_on_blink_timeout)
	$Blink.process_mode = Node.PROCESS_MODE_ALWAYS

func _process(delta):
	pass

func _on_player_hurt():
	lives -= 1
	$HUD/Lives.text = "Lives: %d" % lives
	if lives == 0:
		$HUD/GameOver.visible = true
		$HUD/Hint.visible = true
		get_tree().paused = true

func _on_blink_timeout():
	if lives == 0:
		$HUD/GameOver.visible = not $HUD/GameOver.visible
