Godot 3.2.3 Inheritance GDScript Call Parent Function

Lets say you want to have two GDscripts where the ChildScript.gd will call ParentScript.gd.

From there, you want the ChildScript.gd to call its parent function.

Create Class Inheritance

You first create inheritance in GDScript by calling “extends”.

extends "res://gdscript-filename.gd"

#example
extends "res://Parent.gd"

extends "res://gdscript-filename.gd"

#example

extends "res://Parent.gd"

Call Parent Function . Use dot “.” to call parent function

#function example, where child calls parent function
.getText()

1 2	#function example, where child calls parent function .getText()

Download Godot Project Example

In this example, when “Press Me” button is clicked. The label will change to “Parent Child” where “Parent” is return value from parent function while child is from child function.

Godot Button Signal Tutorial

I’m still new to games development using Godot engine.

I follow the button signal tutorial on Godot website. I created the project for easy reference for others because at the website they don’t provide the Godot project that you can immediately play.

Full GDScript from the tutorial

# Declare member variables here. Examples:
# var a = 2
# var b = "text"


# Called when the node enters the scene tree for the first time.
func _ready():
	#pass # Replace with function body
	get_node("Button").connect("pressed", self, "_on_Button_pressed")


# Called every frame. 'delta' is the elapsed time since the previous frame.
#func _process(delta):
#	pass


func _on_Button_pressed():
	# pass # Replace with function body.
	get_node("Label").text = "HELLO!"

# Declare member variables here. Examples:

# var a = 2

# var b = "text"

# Called when the node enters the scene tree for the first time.

func _ready():

#pass # Replace with function body

get_node("Button").connect("pressed", self, "_on_Button_pressed")

# Called every frame. 'delta' is the elapsed time since the previous frame.

#func _process(delta):

# pass

func _on_Button_pressed():

# pass # Replace with function body.

get_node("Label").text = "HELLO!"

Download Godot Button Signal Project

You can download the button signal Godot project here, if you want to run the tutorial.

In case the button signal tutorial is broken link for what soever reasons, I have converted the web page into PDF.

Hope it helps beginner games developer like me.
