I dunno, but first of all my sentry fell veeeery slowly when used with gravity gun and such.
(Modified the drag (and mass, however not needed that much i guess) to 0.6 in Player_Turret, and now it falls nicely..)
Secondly, my sentry seems to attack zombies only if they are attacking him sometimes.
It is really weird...
Oh, and my sentry can turn around, so it can attack me if i am behind it.
Is this normal?
If yes, is it possible to make it so he can turn just a little bit?
Aside from these things, this add-on is very nice.
