2D Pos -> Int

I made a 2D Position -> Int -> 2D Position encoder/decoder.

Has this been done before?

Ehm LOWORD and HIWORD ?

Oh and why do you need this ?

How well does it handle core::position2df or core::position2di(1 << 16, 1 << 16)?

I don't need it, I just thought it'd be fun to make.

Code: Select all

struct P{
 s16 x;
 s16 y;
}
// create a new 16 bit struct 
P p = (10, 10);

// put this position into an int
s32 myposition = (int)p;

// put the int back into the stuct
P backPos = (P)myposition;

//put the stuct into a irrlicht position
core::position2di m = new core::position2di(backPos.x, backPos.y);

I'd appreciate some critique, my C/C++ is getting a bit rusty
