Godot - Creating a Signal for When a Button is Clicked

This code example shows how to create a signal in GDScript that is emitted when a Button node is clicked.

You can create a signal for when a Button node is clicked using `pressed.connect()`.
The function name is specified as the argument.
The created signal can be implemented with an execution event as follows.

# Create a Button node
var button = Button.new()
add_child(button)
button.text = "Button"

# Button node click event
button.pressed.connect(_button_pressed)

The created signal can implement execution events as follows.

func _button_pressed():
	print("Button Pressed")
