Question

I want to be able to use math functions on my “vector3D”s like so

vector3D a = v3d(1.0,1.0,1.0);
vector3D b = v3d(2.0,0.0,5.0);

a+=b;
vector3D c = a*b;

The code for my typedef struct:

typedef struct _vector3D{
    float x;
    float y;
    float z;
}vector3D;


static inline vector3D
v3d(const float x, const float y, const float z)
{
    vector3D v = {x,y,z};
    return v;
}

How do I allow my typedef struct vector3D to handle this operators?

Answer 1

C, and therefore Objective-C, does not support method overloading.
You’ll have to write your own add and multiply functions instead.
