help about kOS

[veggero]

I need a help whith kOS.

How i can get:

1) The x-velocity and z-velocity of the ship?

2) Antitarget?

Answer to (1):

What do you think x and z are? Do you mean relative to the universe's axes? I assume not because that's just the :X and :Z components of the velocity vector SHIP:VELOCITY:ORBIT (or SHIP:VELOCITY:SURFACE, depending on which you wanted), which would be too easy of an answer.

I suspect you mean relative to your ship's facing - as in the fore direction and the starboard direction.

If that's the case, then you can get that with dot products of the vector with the ship's current facing axis vectors:

SET STARBOARD_VEL TO VDOT( SHIP:FACING:STARVECTOR, SHIP:VELOCITY:ORBIT).

SET FORE_VEL TO VDOT( SHIP:FACING:FOREVECTOR, SHIP:VELOCITY:ORBIT).

Answer to (2):

As a vector:

SET ANTI_TARGET_VECTOR TO (-1) * TARGET:POSITION:NORMALIZED.
