create station behind ship

[marsrocks]

I'm still learning by reading codes other people have made.

In the one I am working on now, I am trying to create a station (an object, actually) which I want to appear a few sectors behind the player ship.

Below, is as close as I have gotten.

This code will place a station 5 sectors in front of the player ship:


(block (newStation)
(setq obj (sysCreateStation &stCrateFunCrate; (sysVectorPolarOffset gPlayerShip (shpGetDirection gplayership) 5)))
)

I have searched for other codes to try to figure out how to select the angle behind the ship, but can't really understand what I am seeing. I have plugged numerous things in, but always get errors.

The thruster mod code seems closest to showing me how to find the angle behind the ship, but nothing I have tried so far works.

This is the thruster code for reversing direction of the ship from Prophet:

;; BRAKES
(and (leq (sysVectorSpeed (objGetVel gSource)) (shpGetMaxSpeed gSource)) (eq aWeaponType &itThrustReverse;))
(block Nil
(setq newAngle (add (shpGetDirection gSource) 180))
(objIncVel gSource (sysVectorPolarVelocity newangle 1))
(sysCreateWeaponFire
&vtThrusterExhaust;
gSource
(sysVectorPolarOffset (objGetPos gSource) (add 180 newAngle) 1)
newAngle
(multiply (sysVectorSpeed (objGetVel gSource)) -1)
Nil
)
)
)
)

So, this is probably easy for you guys - but difficult for me, but how do I write the code to place the station behind the ship instead of in front of it?

Try adding 180 degrees so that it faces the other way? :S

Code: Select all

(block (newStation)
(setq obj (sysCreateStation &stCrateFunCrate; (sysVectorPolarOffset gPlayerShip (add(shpGetDirection gplayership)180) 5)))

That works perfectly!

Thanks, RPC!
