2D Practice Shaders in Godot
31Godot 2D Practice Shaders Series
In this episode I'll introduce the first 3 shaders (out of 14).
We'll learn the basics of CanvasItem Material shaders in Godot and how to change the pixels of our 2D images and sprites using the built-in shader language.
SHADER 1 ColorChannelRed - change the red color channel of a texture
SHADER 2 ReplaceColor - replace some colors in a texture with another color
SHADER 3 RadialHue - change the texture pixels based on their UV position
The code covered in this series is heavily simplified to help us learn about shaders but the original code for each shader can be found on godotshaders.com
