Godot 4 Shaders: Write 2D shaders for your game from scratch | Udemy

Welcome to the “Godot 4.x Canvas item Shaders” course on Udemy! This course will guide you through the fascinating world of 2D shaders, where you’ll learn everything from the essentials to advanced techniques.

That being said, the series is split up between a beginner and an intermediate course. You are now looking at the first part of the series. It will take you from a beginner to intermediate in a matters of hours.

What makes this series unique is that it covers everything there is to know about 2D shaders in Godot 4. it’s the most complete 2D shader series to date.  It starts by teaching you the syntax and formatting rules following the community standards. Then you learn each concept with theoretical and practical examples, slowly building up from simple shaders to more advanced examples. It’s also packed with “try by yourself” challenges to not just copy and paste the code but really learn how to do it on your own. The goal of this course is to teach you how to create any 2D shader you envision from scratch.

The content of the course is up to date with godot 4.2

In this part of the series we’ll start by exploring canvas item shaders, Godot’s unique shading language, and look into essential data types like floats, integers, arrays, vectors, matrices, etc. You’ll learn concepts like:

• Color channels
• Texture mapping
• Uniforms
• Wrapping modes
• Formatting
• Built-in functions
• Hints
• UV Coordinate system
• Fragment & vertex functions
• Render pipeline

And more advanced topics like:

• Pre-processing shaders
• Debugging-shaders & -techniques
• Interaction with GDScript
• Randomness
• Animation Graphs (CurveTexture)
• Interpolation
• Vector operations
• Branch divergence

And the list goes on and on. We will explore these topics through a blend of theory and practical coding exercises.

The course is structured to provide a comprehensive understanding of shader language. It exists out of two project, a project where we mostly focus on the theory and create random shaders that fit the subject, and we’ll have a actual game project, our “Zombie project“, this is where we learn to apply our knowledge to create visual effects (VFX) for your 2D games. We’ll take a detailed look at every built-in shader function that we’ll be using in our code, explaining every single line. Every time a new functionality is introduced, We’ll have a full explanation using coding examples, slides and follow up questions. Plus, it’s important to know that the course follows community best practices.

By the end of this course, you’ll not only have a solid foundation in shader programming in Godot but also a fun, interactive project to showcase your new skills.

Enroll now to start our journey into the colourful world of shaders!

Im happy to welcome you to the course!

Kind regards,

As a final note:

At this point in time the second part of the series is still under development. I will be working on both this course to make sure it’s up to date and the new course. This way you will be able to advance from intermediate to advance level once the second part is finished.

Topics that will NOT be discussed in this course, but will be included in the upcoming part 2 are:

• Applying matrices on vertices
• Screen space shaders
• Canvas space shaders
• Screen texture
• Post-processing shaders
• Advanced vector operations
• Global uniforms
• Coordinate space transformations using transform matrices (world to screen space, etc)
• Back buffer copy
• Advanced UV mapping
• Light function

And other advanced topics. Those will be discussed in the upcoming course.

I will be available for questions after working hours 8:00 – 17:00 (GMT+1 / EST-5) from Monday to Friday, varying times in the weekends. Always try to respond within 12 hours or less!

Note:

Below I update my change log for working on this course. Although my focus lies on working on part 2 of the series, i’ll keep taking notes of incoming feedback and i’ll deal with important issues if they may arise. As soon as the second part is live i’ll invest my time more evenly between the courses. Just want to let you know that I’m working hard on it almost every day to make your experience as good as possible, let’s create awesome shaders together!
