Lives

Part of the Game Rules section of Coddy's Godot journey. Lesson 11 of 29.

Many games give you a few lives. Each mistake costs one, and the game ends when they run out. In code, lives are a number:

var lives = 3

In this room, the player sends its hurt signal when it touches the red spikes. It then goes back to the green square. _ready() already shows the lives and connects hurt to _on_player_hurt().

To lose a life, take one away, then show the new number.

Challenge

Easy

Make the spikes cost a life.

In _on_player_hurt(), take one away from lives.
Then update $HUD/Lives the same way _ready() does.

Press Play and walk onto the spikes: the label shows Lives: 2. Then Check.

Try it yourself

extends Node2D

var lives = 3

func _ready():
	$HUD/Lives.text = "Lives: %d" % lives
	$Player.hurt.connect(_on_player_hurt)

func _on_player_hurt():
	pass
