Vector (API)

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

Static methods
Method name	Description
vector.new(x, y, z)	Creates a vector. @param x, y, z the vector coordinates @return the created vector

Object methods
Method name	Description
vectorA:add(vectorB)	Adds vectorB to vectorA and returns the resulted vector. Can also be used by writing vectorA + vectorB.
vectorA:sub(vectorB)	Subtracts vectorB to 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(vectorB)	Returns the dot product of vectorA and vectorB.
vectorA:cross(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".
