a) Matrix's are already centered on the screen
b) It would be easier to make the man move on matrix.
rem turn off auto cam so camera doesn't mess up while creating objects
sync on : sync rate 60 : autocam off
rem make simple matrix
rem rest is really self explanitory
make matrix 1,1000,1000,10,10
make object sphere 1,15
position object 1,500,30,20
position camera 500,40,0
do
rem control with arrow keys
if upkey()=1 then move object 1,+3.0
if downkey()=1 then move object 1,-3.0
rem update
sync
loop
I am the very disease you pretend to be.
