Hi all,
I am trying to make a player to target view. I cannot figure out how to offset the camera from player ship AND keep it pointed at the target. See attached image. I want to look over player towards target.
Hope that makes sense.

A quick and dirty way to do this would be to locate the camera in the same position as the player, point the camera at the enemy ship, the move the camera backwards, with a command like

move camera -50.0

That way the camera is still pointing at the enemy, but it backs up enough to see the player.

I'm sure there's a way to do the same thing using maths, but I am terrible at math, and lazy besides.

Even Quicker and Dirtier.
I made a dummy object, positioned on player ship,
Pointed it at target
positioned camera @ dummy
orientate to object; dummy
Move camera as you suggested.

+ Code Snippet

position camera 2, Object Position x (203),Object Position y (203)+4,Object Position z (203)
Point Camera 2, Object Position x (201),Object Position y (201),Object Position z (201)
SET CAMERA TO OBJECT ORIENTATION 2,203
move camera 2,-15

I dunno how efficient it is, but it works.

If you rather fancy the elegant way:

(I'm using vectors because it's faster)

+ Code Snippet

set vector2 1, object position x(player) - object position x(enemy), object position z(player) - object position z(enemy)
normalize vector2 1
multiply vector2 1, Distance#

position camera object position x(player) + x vector2(1), Height#, object position y(player) + y vector2(1)
point camera object position x(enemy), object position y(enemy), object position z(enemy)

The same applies in 3D:

+ Code Snippet

set vector3 1, object position x(player) - object position x(enemy), object position y(player) - object position y(enemy) + HeightForVisibility#, object position z(player) - object position z(enemy)
normalize vector3 1
multiply vector3 1, Distance#

position camera object position x(player) + x vector3(1), object position y(player) + y vector3(1), object position z(player) + z vector3(1)
point camera object position x(enemy), object position y(enemy), object position z(enemy)

Cheers!
