Scene transition effects in Godot 3 The Shaggy Dev 2022-06-13 | Let's look at how we can use animations, shaders, and other effects to make better scene transitions in Godot than a simple call to `get_tree().change_scene`. We can do this by adding an autoloaded scene that can act as an intermediary when we want to let an effect play out during scene transition. This also makes it easy to introduce background loading if we want.Sample project: github.com/theshaggydev/the-shaggy-dev-projects/tree/main/projects/godot-3/scene-transitionsText version: shaggydev.com/2022/06/13/godot-scene-transitionsCorrection: 00:03 See the pinned comment for the equivalent syntax in Godot 4!
Communicating between game objects with the observer pattern The Shaggy Dev 2022-06-02 | One of the most common issues you'll run into in your game development journey is how to let two unrelated objects communicate with one another in a way that doesn't completely ruin the organization and flexibility of your code. The observer pattern is one potential solution to this problem, and makes it easy to let different game objects communicate with one another without coupling your entire application together. With native support in most languages and game engines, it really is something you should keep in your toolbox. We can also expand upon this concept further and introduce the event bus, a way of letting more distant objects connect to one another while still keeping the flexibility of your code intact.Text version of this video: shaggydev.com/2022/06/01/observer-patternMore info on the observer pattern: gameprogrammingpatterns.com/observer.htmlBackground and motivation: 00:00The observer pattern: 01:34Observables in practice: 02:52Global access via an event bus: 05:02The event bus in practice: 05:31Final thoughts and further reading: 06:04

Setter and getter functions in Godot 3 with setget The Shaggy Dev 2022-01-05 | Setter and getter functions allow you to write custom logic to be ran when a variable to written to or read from. In Godot, we can define setter and getter functions using the setget keyword, followed by the names of the setter and getter functions, respectively. This video demonstrates the technique along with providing some useful tips for when you're using setget in a project.Text version of this video: shaggydev.com/2022/01/04/setgetOfficial documentation: docs.godotengine.org/en/stable/getting_started/scripting/gdscript/gdscript_basics.html#setters-getters
An introduction to procedural lock and key dungeon generation The Shaggy Dev 2021-12-18 | Let's take an introductory look at lock-and-key procedural content generation. Using a lock-and-key framework to procedurally generate content, you specify paths of progression for the player in your games. Roguelikes, narrative games, and really any sort of game where you want the player to advance via a series of steps (whether linear or non-linear) can be modeled and created this way.Intro: 00:00Definition: 00:56Big key locks: 01:43Small key locks: 02:38Stateful locks: 03:49A sample technique for generating content: 04:36Limitations: 07:14Spatial methodologies: 09:09Conclusion: 10:57Video transcript and code snippets shown in the video available here: shaggydev.com/2021/12/17/lock-key-dungeon-generationMetazelda repo: bytten-studio.com/devlog//2012/11/30/lock-and-key-puzzle-generationIRDC 2014 - Roguey-Locks and the Three Graphs: youtube.com/watch?v=uP3horC38IEUnexplored's unique cyclic graph generation technique: aiandgames.com/2021/01/28/unexploreds-secret-cyclic-dungeon-generation
Callbacks and function references in Godot 3 using FuncRefs The Shaggy Dev 2021-11-29 | While functions are not first-class objects in Godot, FuncRefs can help replace some of that missing functionality. Using the built-in funcref() function, we can create objects that maintain a reference to and can call a selected function anywhere in our code.Intro and first-class functions: 00:00Funcref overview: 01:31Sample project: 02:10Source code: github.com/theshaggydev/the-shaggy-dev-projects/tree/main/projects/godot-3/funcrefText post: shaggydev.com/2021/11/28/funcrefGodot documentation: docs.godotengine.org/en/stable/classes/class_funcref.html
Implementing the state pattern in Godot 3 The Shaggy Dev 2021-11-15 | Let's take a look at how we can implement the state pattern in Godot. Using a simple platformer project, I'll show the basic technique using enumerators and a more fully featured state machine that uses Godot's node system to provide extra conveniences over a pure code solution.Intro: 00:00The enumerator method: 00:53Technique overview: 01:45Player and state manager breakdown: 03:33Individual states: 05:40Conclusion and running the project: 06:58Theory video: youtu.be/-ZP2Xm-mY4EPart three of this series: youtu.be/DPxIMVC0oZASource code: github.com/theshaggydev/the-shaggy-dev-projects/tree/main/projects/godot-3/the-state-patternTranscript: shaggydev.com/2021/11/15/state-machines-godot
An introduction to finite state machines and the state pattern for game development The Shaggy Dev 2021-11-02 | In this video, we'll discuss finite state machines and how they can be used to write cleaner, more maintainable, and more expandable code for your games. We'll look at the naive way of managing state in a game, how we can improve upon that method slightly with enumerators, and finally how to build a robust system using the state pattern.Intro: 00:00Life without state machines: 00:54Finite state machines: 02:38Using enumerators: 04:55The state pattern: 06:09Final thoughts and where to go next: 10:28Game Programming Patterns: gameprogrammingpatterns.com/state.htmlVideo transcript: shaggydev.com/2021/11/01/state-machines-introArtwork by Kenney: https://www.kenney.nl/
Static typing in Godot using the class_name keyword The Shaggy Dev 2021-10-20 | In this video, we'll look at how you can use the class_name keyword to enable static typing for your custom classes. We'll also look at some other uses for it, such as subclassing, and the common pain points people run into when using it (cyclic dependency anyone?)Source code: github.com/theshaggydev/the-shaggy-dev-projects/tree/main/projects/godot-3/class-name-introductionText version of this tutorial: shaggydev.com/2021/10/19/godot-class-nameArtwork provided by Kenney: kenney.nlIntro: 00:00Base usage: 00:29Other uses: 01:18Gotcha #1 - The global namespace 01:59Gotcha #2 - Cyclic dependencies 02:52
Using a Polygon2D node to create physics bodies in Godot The Shaggy Dev 2021-10-12 | In this video, I'll demonstrate how you can use the Polygon2D node to create both static and rigid physics bodies in Godot. This method allows us to create more custom level geometries than we could otherwise get out of a tilemap, but also let's us iterate on designs faster than making an object outside of the editor.Source code: github.com/theshaggydev/the-shaggy-dev-projects/tree/main/projects/godot-3/polygon2d-physics-bodyTranscript: shaggydev.com/2021/10/11/polygon2d-physics-bodyGodot Bordered Polygon2D Plugin: github.com/arypbatista/godot-bordered-polygon-2dIntro: 00:00The Polygon2D node: 00:51Project setup: 01:48The static body scene: 02:26The rigid body scene: 03:01Results: 05:00Final thoughts: 05:22
Animating a hardware cursor in Godot - An experiment The Shaggy Dev 2021-10-05 | In this video, we'll take a look an experiment I wanted to run: using the hardware cursor interface in Godot but animating it like a software cursor.
