move particle direction with player

Hello, I've got an character in 3rd person and made him shoot particles via spawnpoint when he pushes a button.
My problem is now that this particle effect shoots and collides with walls etc but it goes always in one direction and doesn't move when the character does / rotates.

What I tried:
I already tried with the force function in the particle inspector itself,
tried simulate in worldspace
(from http://answers.unity3d.com/questions/46391/make-particle-system-emit-in-players-forward-direc.html)
and tried to move the spawnpoint with the particle in it as a child (to be honest this was dump cause the particle always gets spawned on a click)

all those steps didn't help, do u got any ideas how to solve this?

regards,

Soul
