PVector& add(PVector other)
Adds the components of the other vector to the vector that is operated on. This function is equivalent to using the operator+= function.
This function returns a reference to the vector that the function was called on to use in chaining.
Parameters
other- The vector to add to the current vector
Returns
A reference to the vector
Examples
PVector v = PVector(1, 2);
PVector o = PVector(3, 4, 5);
v.add(o);
/*
v.x == 4
v.y == 6
v.z == 5
