is it possible (in DBC) to make the camera circle around the 3d object that I am using for a player. I need it to change based on mouse movement. (ex. mouse moves to the right 1, camera circles 1 degree)

also, is there any way to turn (not rotate) a limb. Like the turn object and turn camera commands but with limbs, cause I could do the camera thing using that too

thanks in advance

Well rotating an turning are pretty similar if you use them right. And if you have a 3rd person camera set up then just detect if the camera is close to left side of the screen or right and inc or dec a varaible for the angle of the camera.

There are different ways of achieving orbital motion. You could attach the camera to the end of a hidden limb and rotate the limb, but for more flexibility I would use maths to position the camera at the right place. The maths you need is the equation for a circle: x=radius*sin(angle), z=radius*cos(angle)

Here's an example:

+ Code Snippet

sync on
autocam off
make matrix 1,20,20,20,20
make object cube 1,1
position object 1,10,0.5,10

radius=10
cameraheight=5

do
x#=radius*sin(angle#)
z#=radius*cos(angle#)
inc angle#,mousemovex()

if leftkey()=1 then turn object left 1,1
if rightkey()=1 then turn object right 1,1
if upkey()=1 then move object 1,0.1
if downkey()=1 then move object 1,-0.1

position camera object position x(1)+x#,cameraheight,object position z(1)+z#
point camera object position x(1),object position y(1),object position z(1)
sync
loop
