distance is
dx=x2-x1
dy=y2-y1
dz=z2-z1
d=sqrt(dx*dx + dy*dy + dz*dz)

delta y u can use for up down new y = old y + value

SetCameraLookAt
MoveCameraLocalZ move for or back belongs distance
GetCameraX
GetCameraY
GetCameraZ
SetCameraPosition
GetObjectX
GetObjectY

Here's an example of a simple 3D driving game which has a simple 3rd person camera.

It's written in V1 but works in V2.

you can also use atanfull to turn the player around if you have 2 cords for the player, and 2 cords for what it needs to look at. you can use atanfull if the object moves on the xy plane.
