Breakout Game Over

Part of the Projects section of Coddy's Godot journey. Lesson 9 of 36.

Three misses should end the game. At zero lives, show Game Over and pause with get_tree().paused = true. The paddle and ball are Pausable, so they freeze. Main is Always, so it keeps running and can read Enter:

func _process(delta):
	if get_tree().paused and Input.is_action_just_pressed("action"):
		get_tree().paused = false
		get_tree().reload_current_scene()

Unpause before you reload. The pause belongs to the tree, not the scene, so a reloaded scene would start frozen.

Challenge

Hard

End the game when the last life is gone.

In _on_missed, when lives is 0, show Game Over in $HUD/Message and pause the game.
Add _process: when the game is paused and action was just pressed, unpause it, then reload the scene.

Press Play and miss three balls: Game Over shows and the ball stops. Enter starts again. Then Check.
