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”.

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

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

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.

Payment from Nuffnang for My Advertisement Income

I put Nuffnang advertisement on my blog. I requested for pay out for my ads income.

I requested on 25th Nov 2020 and received the check on 16th January 2021. It took nearly 2 months to get the check.

Based on my experience with Nuffnang, its income not as good as before and better use Google AdSense. My blog rarely shows any Nuffnang advertisement maybe due to low traffic. Ha ha
