Is it possible to detect the roll angle value of the camera and then roll it so that it is facing up again? I am doing an FPS, and I have my camera looking code down(so that you can rotate the camera with the mouse). My problem is that when you look down, and then move the mouse to the side, the camera becomed angled. So here is my question in a nutshell:

How can you make a slanted camera unslanted w/o using commands like yrotate camera and xrotate camera (these make the entire thing even more glitchy, already tried)?

BTW: I am using DBC

Thanks in advance

In testing get the X/Y/Z of the camera when it is facing the right way, and put them in variables. Now you can roll the camera back to these positions whenever you want. I did it with a 3D dice program when I wanted the dice to always face the player.

Actually they aren't X/Y/Z positions, they are X/Y/Z rotation angles. This is my Dice program hacked. Pos 1,2,3 are the final angles to face the right way for the number 6 on a dice. Different Pos will give a different number on the dice. It relates in the same way to rotating a camera back to its start position. This example will need some changes for it to work in your program, but it shows you how to do it slightly.

pos1 = 270
pos2 = -270
pos3 = -270
x# = curveangle(pos1,x#,20)
y# = curveangle(pos2,y#,20)
z# = curveangle(pos3,z#,20)
cameraz# = curveangle(0,cameraz#,20)

xrotate object 41,x#

yrotate object 41,y#

zrotate object 41,z#
zrotate camera cameraz#
