Quote: "-Also rotate camera x,y,z use local or global?"
It will rotate X first, then Y, then Z
Quote: "-Pitch/Turn/Roll Camera use Local or Global?"
Local
Quote: "Recently,I test that XRotate Camera.But XRotate Camera Or Rotate Camera x,0,0 like that It's always the same direction."
Try
Rotate Camera 1,0,0
and
Rotate Camera -1,0,0
it's easy to test things like this with a few lines of code, for example...
sync rate 60
make object cube 1,3
xrotate object 1, 45
do
rotate object 1, object angle x(1),object angle y(1) + 0.1,object angle z(1)
loop
