PVector& sub(PVector o)
Subtracts the components of the other vector to the vector that is operated on. This function is equivalent to using the operator-= function.
Parameters
other- The vector to subtract from the current vector
Returns
A reference to the vector
Examples
PVector v = PVector(1, 2);
PVector o = PVector(3, 4, 5);
v.sub(o);
/*
v.x == -2
v.y == -2
v.z == -5
*/
