Hey all! This is Tutorial about setting up a basic Continuous Integration Pipeline in GitLab In this video I'll: - Explain how a basic pipeline works for automating your development work - Create a Gitlab pipeline CI - To automatically create exports for all platforms - This will happen everytime you update your release branch (and you're ready to release a new version of your game) - Talk about how to extend this pipeline for automated testing - Show real world working examples of how you can use this in a team environment Please let me know any clarifications, questions or comments :)

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.

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...

Programming Tutorial Bits: Kotlin Data Classes https://www.youtube.com/watch?v=Telif4fZtrs This is a great place to start learning Kotlin if you have even basic Java experience.  More videos to come. In this video we will learn:  How to use data classes in Kotlin.   How to decompile Kotlin code to understand what it provides  What Kotlin improves on from Java with data classes   We will also touch on Nullable and Non-Nullable types and what happens when we try to call a non Nullable type with null form Java (Oh noes!!!) Clarifications:  Auto Get and Set generation:   If the member is declared with var and is accessible to class users (not private etc) you have access to setters and getters - If it is declared with "val" this NO SETTERS are generated. "val" is essentially like declaring "final" in Java the world.   EXPERIMENT AND TRY IT OUT! :) !! Not-Null assertion operator I touched a little the ...

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...

Hey guys so you want a level editor but don't want to build one yourself right? Who does? You basically need to create a entire tangential project, with full GUI editor and undo tree etc. Unless that's a goal of yours (selling etc?) you probably want an easier solution. Well folks, look no further than your good friend Blender 3D. The same tool you use for modeling crazy cartoon knights swinging swords and whatnot, can be your level editor for your 2D game. A Plan So how do we do this? What do we need? We need a output format that's easy to parse. We need to decide on attributes that we can assign meaning to (for box2D and our game) The texturing and vertex placement etc, comes for free since we're using a 3D modeling format :) The OBJ file format. Why OBJ? This is super easy to parse. You could use another format, if you're already using a parser (I recommend ASSIMP :) ), but for this tutorial, I'm going to use OBJ so you ca...
