Try placing an object just in front of the camera. Use this code within your loop:

+ Code Snippet

position object obj,camera position x(),camera position y(),camera position z()
move object obj,0.5

Then print the object coordinates.

Have fun in whatever you do, no matter how sad it is.

Or, use the NewX, NewY, and NewZ commands.

common people are walking in line.

or use pick screen (only in DBP I believe)
if you have dbp, then I think it would be the fastest and easiest way.

+ Code Snippet

autocam off
sync on
sync rate 60
hide mouse
make object cube 1,10
position camera 0,0,-30
do
sync
free_flight(0,1)
pick screen screen width()/2,screen height()/2,1
text 0,0,"Point 1 space infront of camera:"
text 0,20,"X pos: "+str$(get pick vector x()-camera position x())
text 0,40,"Y pos: "+str$(get pick vector y()-camera position y())
text 0,60,"Z pos: "+str$(get pick vector z()-camera position z())
loop


function free_flight(cam,speed#)
move camera cam,speed#*(upkey()-downkey())
x#=camera angle x(cam)
rotate camera cam,0,camera angle y(cam)+90,0
move camera cam,speed#*(rightkey()-leftkey())
rotate camera cam,x#+mousemovey()/2.0,camera angle y(cam)-90+mousemovex()/2.0,0
if camera angle x(cam)>90 then xrotate camera cam,90
if camera angle x(cam)<-90 then xrotate camera cam,-90
endfunction

Insanity is just a state of mind.

Or do this:

+ Code Snippet

x#=camera position x()
y#=camera position y()
z#=camera position z()
ax#=camera angle x()
ay#=camera angle y()
dist#=10
cx#=x#+(sin(ay#)*cos(ax#)*dist#)
cy#=y#-(sin(ax#)*dist#)
cz#=z#+(cos(ay#)*cos(ax#)*dist#)
