Add Object with logicbricks in upbge 0.3

I try to spawn a bullet from a empty-obect, but it´s dont work.
Can anyone explain to me like a real newbie how to make it work.
Layers are replaced by collection in blender 2.8, and I dont find a answer on google.

This will help

thanks mah dude! It´s works like a charm.

Just hide it with H in the 3D viewer or click on the eye beside it’s name in the Outliner.
