If you set only roll camera + rotate camera,when rotate y-axis,
camera will reverse.
But Zrotate camera (Zero) + Roll Camera work very well.
It helps who want to make perfect roll camera.
I wish It helps your projects.

I have to disappoint you again...

set camera fov 72

This number is in radians, not in degrees. You can calculate the degrees with this formula:

fov#=(3.14/180)* degrees#
degrees#=(3.14/180)/fov#

so 72 radians would equal about 7.8 degrees, which is quite small, I would imagine.

Secondly, you forgot the "sync" command, which should refresh the screen every loop.

You can totally forget this line:

if Upkey() = 0 and Downkey() = 0 Then Move Camera 0.0

Because the camera won't move anyway if you don't push any button. The same for the next line:

If Keystate(DIK_A)=0 and Keystate(DIK_D)=0 Then Roll Camera Right 0

Nice use of the constants.

Oh So Sorry!
I think I make this code very simply.
However I learned more knowledge that I didn't thought like Fov is Radian and blah blah~!
Thank you So Much!!

@ thecomet

Most angle values in DBPro are in degrees, not radians, and set camera fov is no exception. Try running this code:

that code sets the fov using degrees. Now try this code:

That uses radians, and it's obvious that it doesn't have the desired results.

That's very odd... In DBC you have to use radians. Why would Lee change it?
