Section 4: Normals Explained

I really recommend looking up about normals, vectors, and anything else explained here in other places so as to help you understand these things better, as I’m still learning how to teach.

You can check out the Godot documentation concerning vectors, transforms, and matrices here:

http://docs.godotengine.org/en/stable/tutorials/math/index.html

If that link doesn’t work go to the Godot documentation and look up “Math” or “Vector Math” and go from there.

You’ll need to know about coordinate systems, like “x” and “y” positions, to understand this section.

This section talks about 2D and 3D vectors as used in GDScript and in 2D and 3D graphics. Vectors as used in programming languages are similar but different. There’s no need to worry about them now. Just remember that this is all for use in GDScript and Godot.
