Camera Question -Coding in Blitz3d-

[Chad]

I'm trying to create a rocking feeling while playing so keep that in mind.

With help off of IRC I have came up with the following code. Basically, it is WolRon's FPS example code with my

RotateEntity camera,Sin(MilliSecs()*.05)*.5,0,Sin(MilliSecs()*.05)*.5

However, with this I cannot use my mouse to look up and down, it stutters. And keeps it still. How can I use my Sin code but still have the full capabilities of my mouse look?
