Predetermined Unit Offsets...

[jcj94]

I'm not sure if this has been resolved, because I remember reading awhile back that someone wanted to "automatically add" the unit offsets of +31 and -1 .  While searching through SDK code and found these lines

Code: [Select]

// Useful macros
#define MkXY(x,y) (LOCATION(x+31,y-1))
#define MkRect(x1,y1,x2,y2) (MAP_RECT(LOCATION(x1+31,y1-1),LOCATION(x2+31,y2-1)))
#define XYPos(x,y) x+31,y-1
#define RectPos(x1,y1,x2,y2) x1+31,y1-1,x2+31,y2-1

// X and Y offset consts
const int X_ = 31;
const int Y_ = -1;

I found these while looking through the OP2Helper.h file that is included.  I am unsure if thise would help or not, but could it?

No, because on "around the world" style maps the offset is (-1, -1) and we have no way of knowing map dimensions at compile time.

It's already in the SDK header files, why does this need to be reposted in the forum?

Honestly these macros aren't even that good because the x and y aren't wrapped in parentheses so order of operations could end up being ambiguous.
