So problem is that bullets doesn't spawn on choosen image points? If so did you make image point on the sprite AND didn't you forget to set right image point in action "spawn object bullet ( image point "...")"? Also check image point on the bullet. If it still doesn't work send a capx I will take a look on it.
PS: "...my player is connected to a player box by everytick..." You have event that says "every tick -> set position to playerbox"? Using Pin behaviour might be better (You just pin once).
