Umm, did you ever do high school maths? well, if you're asking, i think no...

I can't really explain it cos i can't put pics on the net, but if you email me, i'll send you some pictures that will fully explain it.

@DBoy780: I though the 286 was still a hot machine...

My game course has interupted my Alienware compo. No more sweet ass comp for me. Plus I have no more webspace.

Here is an example of SIN, so that the camera is always behind an object (I use this in a race game):

AngleY# = object angle Y(10)
CameraZ# = Object Position Z(10) - sin(wrapvalue(AngleY#+90))*50
CameraX# = Object Position X(10) - sin(wrapvalue(AngleY#))*50
CameraY# = Get Ground Height(1,CameraX#,CameraZ#)+30

(This may be different in some other programs)

Let me explain this:
The SIN calculates where the camera should be, and the * 50 puts the camera 50 units behind the vehicle, I prefer math instead of the build in newxvalue (etc) commands.
