Description Multiplies a vector by a scalar or multiplies one vector by another.
Syntax
vec.mult(scalar)
vec.mult(v)
PVector.mult(v, scalar)
PVector.mult(v1, v2)
Parameters
vec any variable of type PVector
scalar float: the number to multiply with the vector
v PVector: the vector to multiply by the scalar
v1 PVector: the x, y, and z components of a PVector object
v2 PVector: the x, y, and z components of a PVector object
Returns None or PVector
