Vectors and matrices at their core are a set of numbers that represent something (e.g. a Vector3 could represent a position in the world.)
Vectors are one-dimensional; for example, a Vector3 holds 3 numbers. Vectors are most commonly used for representing the position and rotation of things.
Matrices are two-dimensional grids. All matrices are square, so a Matrix3 is a 3 by 3 grid of numbers. Matrices are most commonly used to represent transformations of vectors. For more in-depth information, see the Wikipedia article on transformation matrices.
Vectors
Many functions that take in a vector will also take in the same amount of numbers and internally convert it into a Vector.
Vectors come in 3 types: Vector2, Vector3, and Vector4. The number refers to the size of the vector (Vector4 has 4 numbers, etc.) You can create a vector by using the global method vec
as shown:
This method will return a vector based on how many arguments you input.
Matrices
Matrices are a set of vectors, which are normally used to change where models are, how they look, etc.
