Or whatever it is called.
I just discovered something you may or may not know. If this is obvious knowledge, please delete this thread admins. If not, prepare to shit brix.
I was posting about my camera a couple of days ago, and I found the ULTIMATE solution.
If you put center camera on me on two objects, one on your character, and one on something else that will stay within the screen with your character at the same time; the camera centers between them.
I realised this while toying with sine movement. It makes the perfect camera for me, I have the other thing set to the xhair, so maximized the character will not go out of the screen.
