The vector API provides methods to create and manipulate vectors. An introduction to vectors can be found on Wikipedia.

Vector (API) | |
| vector.new(x, y, z) | Creates a vector. |
| vectorA:add(vector vectorB) | Adds vectorB to vectorA and returns the resulted vector. Can also be used by writing vectorA + vectorB. |
| vectorA:sub(vector vectorB) | Subtracts vectorB from vectorA and returns the resulted vector. Can also be used by writing vectorA - vectorB. |
| vectorA:mul(n) | Scalar multiplies vectorA with n and returns the resulted vector. Can also be used by writing vectorA * n. |
| vectorA:dot(vector vectorB) | Returns the dot product of vectorA and vectorB. |
| vectorA:cross(vector vectorB) | Returns the vector which resulted in the cross product of vectorA and vectorB. |
| vectorA:length() | Returns the vector's length. |
| vectorA:normalize() | Normalizes the vector and returns the result as a new vector. |
| vectorA:round() | Rounds the vector coordinates to the nearest integers and returns the result as a new vector. |
| vectorA:tostring() | Returns a string representation of the vector in the form of "x,y,z". |
