Guess this:
Vector pos;
pos = pobj->GetPos();
Ok....nice so far. I snapped the grid to 1.0, so I only get full coordinates, no float values.
INT x = pos.x;
Also sounds ok.
Guess pos.x = 29.0000 ( this is what vc debug says ) Then, x = 29...in most cases, sometimes its 28!!!!!!!
Any ideas?????????????????????

Hm, SAVELONG( ) seems to solve the problem.....but why is it a problem? I always wrote int = float without thinking about it....did I not understand something essential, or whats going on?

Floating point numbers only have finite precision. Since the INT conversion just scraps the decimals, it might happen that you lose 0.9999. Use something like "INT x = pos.x + 0.5" if you want to round to the closest integer.
(Btw, please limit the number of consecutive punctuation marks to three, in order to reduce forum bandwidth use.)

Yes about the 0.9999 I did of course know, I just wondered because I set the initial objects position to 0/0/0, and move it with grid width 1.0, so decimal places should be all zero. Even if I debug it, they are zero, I thought the debug of vc shows the exact values of the variables, but not only an approximate value

you could also use Ceil() for example (or Floor() for the vice-versa result)
