Duck Typing and Interfaces in Gdscript and Kotlin: Advantages and Disadvantages



Hey all,


I'm sure you've heard the term "Duck Typing" thrown around in regards to Godot's gdscript. In this video I present a simple explanation of what it means and how flexible and powerful it is.


I also do a quick comparison to other programming analogous programming concepts such as programming to Interfaces (Kotlin), and the advantages and disadvantage of using each.

Development on Android NDK Tutorial - Gluing C++ Native Code to Java

Image
Too busy to draw this time.. for now here's a picture of an Android Toy Ok, in this post I am going to talk about how to join C++ native code to a thin Android Java code layer.  I am not going to be doing all native code, as I think the easiest route is to use the Android higher level convenience SDK for loading resources/file I/O, setting up OpenGL context and other state management. I won't be using any IDEs or anything else to complicate things.  This is as easy as it can get, you get the source and type "make" (I assume you are on a system with GNU make, and your environment is setup correctly.  Linux is easiest, but it should run fine on ANY system that can run Make, even Windows!). So the code will be structured like this: -----------------------------------  Android SDK OS Layer code -----------------------------------   Java App Thin Layer to Android OS -----------------------------------   Native C++ code called by...

Video Version Asset Creation : https://www.youtube.com/watch?v=udbPym1JjkY&t=192s Shaders: https://www.youtube.com/watch?v=-W_2OzjnUl4 OK so you have that cool 2D Bubble Bobble inspired game but you want to add some modern flare?  Or maybe you just got some random pixel assets you'd like to experiment with adding fake "refraction" too?  I've got you covered!   Cheaters that don't want to read? You when you don't read this tutorial For cheaters, here's the code, right away, to play with : https://github.com/Razzlegames/GodotBubbleShaderTutorial Refrac-What? So what is refraction?  In simple terms light bends and changes direction as it goes from one medium to another. For example when it passes through water in a glass, it slows down and changes direction causing a distorted appearance to anyone looking through the glass.  Different materials have different refraction amount, and the angle and effect is more pronoun...

Godot Tutorial: How to read all files in EVERY sub directory (Breadth/Depth first Search)

Godot Tutorial: How to read all files in EVERY sub directory (Breadth/Depth first Search)     Hey all, So I was thinking of writing some automated smoke tests in Godot for a project I'm working on and I realized, I don't think I've ever done directory I/O in Godot. - The tools is so well integrated that I've never really had to mess with it yet. - I'm willing to bet many of you guys haven't either. - Don't worry it's easy, lets get into it. You'll learn: - How to read all files in a directory to process however you'd like - How to use Depth First Search - How to use Breadth First Search - The order that both search styles will traverse a tree Code From Tutorial: How to use: - Create a "Node" type of Godot Node    - Note in Video I used Node2D which is OK, but slighly better to use plain Node since no 2D coords etc are needed - Attach this script to that Node: https://gist.github.com/Razzlegames/28dcb74ba...
