Try this:

When you first load the settings and stuff(eg player pos, sin/cos tables
ect...) Set up the min/max view angle...then as they move just add the
correct value to min view angle(and then add 135(180-45) and you get your
max view angle....this ~SHOULD~ keep everything lined up correctly...

eg..

plarer angle = x
player minview = x + viewangle min
player mxview = player minview + 135

~action: player moves his/her view

plarer angle = x
player minview = x + viewangle min + 5
player mxview = player minview + 135

this ~looks~ right
you tell me

The all knowing Grape(just thinks he is)
PS.. let me know if this works
