I am new to DB. Ive been programming for 3 years though in VB. I was in the process of learning DX when i found DB. Now i want to go completely to DB for any game i make. For one of my first programs i was going to make a program with a matrix that you walk on following a 3d model and avoiding different walls. I was going to do this to learn colllision detection and all that other good stuff. Well i ran into a little problem. When i spin the camera around the matrix tilts and i can not figure out why. Plus the camera always seems to point down. If anyone could look at the code and tell me whats up it would be much appreciated. The code is just matrix and camera code not the full test project. Thanks

make matrix 1, 100, 100, 100, 100

position camera 50, 3, 50

do
set cursor 0, 0

if UPKEY() = 1 then move camera 1
if DOWNKEY() = 1 then move camera -1
if leftkey() = 1 then turn camera left 1
if rightkey() = 1 then turn camera right 1

loop

by default the camera starts off looking down slightly at the 0,0,0 position, to stop yourself submerging under the ground as you move forwards, set the camera level like this

autocam off:rem stops the camera pointing at anything you may create on the level
position camera 50,3,50
point camera 51,3,51:rem this makes the camera point level to the z plain by pointing one world unit away at the same height

and inkey$() returns the string value of the keys on the keyboard, so inkey$() returns "d" when you press the "d" key, or " " when you press the space key, you have to use the other commands to read keys like F1 or home that don`t have visible characters (like upkey for example), cheers.
