How can I move the camera along te path of a circle around my object?

Can i just make a circular path or does it involve equations like z=sqrt(r^2-x^2)

Anybody know? I'm basically trying to get it to where my camera moves in a circular path around my object whenever I move the mouse sideways left or right.

Please help ^_^

Sorry if this doesn't help, but this is the best I can do:

Use the newxvalue(), newyvalue(), and the newzvalue() functions to position the camera according to the object, and then point it at the object.

EDIT:

Actually, this should be alot more helpful now that I made an example demo:

+ Code Snippet

sync on
camang# = 1

`CHANGE THESE VARIABLES TO WHAT YOU WANT
Distance# = 10
Height# = 25

make object cube 1,5
Position object 1,100,2.5,100
Position camera 0,0,10
Point camera 0,0,0

Make matrix 1,200,200,20,20

Do

   Camang# = wrapvalue(Camang# + 1)
   Position camera newxvalue(object position x(1),camang#,Distance#),Height#,newzvalue(object position z(1),camang#,Distance#)
   Point camera object position x(1),object position y(1), object position z(1)
   sync
Loop

I hope it helps
