here is the distance formula, but it only works if you have x, y, and z formula coordinates of the 2 points

(x[2]-x[1])^2 + (y[2]-y[1])^2 + (z[2]-z(1])^2

then square root that and you have your distance

but putting that into a formula on a program may be fairly hard
The numbers in brackets [] represent the subscript number, the ^ represents that the following number is an exponent

To calculate the straight line distance in DB between object 'objnum' and the camera use:



The variable Distance contains the distance between camera and object.

If calculating the distance between two objects, then use the other object's X, Y and Z positions instead of the camera's.

although this may not work, it should give you an idea of the distance formula made in BASIC


if i mixed up the way it is then excuse me. although that is not actual code (i dont think), it should show you how you would program the distance formula i posted.
