Rotating issues

[Mazuho]

In a 3dgame I am currently developing I am having a bullet "spawn" from a model
resource every time the user shoots with his/her tank. Let's say that when the
game starts the turret is in position A. The user rotates the turret x degrees
and fires, and the bullet should fly away in the direction the barrel is
pointing in. My problem now is that the bullet always goes in the same
direction. It gets spawned from the tip of the barrel just as it should, but if
I make a 180 degree turn, the bullet flies into the tank instead.

This is the code for positioning the bullet when it gets spawned:

bullet = w.newmodel("bullet"&string(pcount), bulletR)
bullet.worldposition = w.model("turrettarget").worldposition

--pTurretEnd is a small invicible box at the end of the barrel

This is the code for the trajectory of the bullet:
--BulletV = vector(-20,0,0) BulletH = vector(0,0,0.1)
bullet.transform.translate(BulletV)
bullet.transform.translate(BulletH)

Any ideas?

Okay, I solved it by doing the following:
1. Getting a vector from the beginning of the barrel.
2.Getting a vector from the end of the barrel.
3. vector c = vector a - vector b
4. normalized vector c
5. translated the bullet along the direction vector now aquired (vector c)

Hope someone finds this useful
