Converting isometrics coordinates

[TomCrowQQ]

Hello...i need help to write fuction for convertiog isometrics coordinates to the "real" coordinates... this picture should help with explaining:

the 60 x 90 is the isometrics coordinate...
Thanks for answers :)

This looks like an advanced topic that has to do quite little with C++. Just saying.

I tried many of these... but my brain is too stupid... Because.. the "map" is from one game.. and its rectangle, but the game is isometrics..

I'm guessing that the reason why it's complicated is that an isometric drawing can handle 3D coordinates, (x, y, z). For 2D (x,y) it will surely simplify to a fairly straightforward conversion with a couple of equations.

I did it :)

real x = (x - y) * 32 + 6912
real y = (x + y) * 16 - 1980
