It attaches the entity on the weapon attachment 1 I guess, something like. But you can do that probably because it a custom entity (FL_CUSTOMENTITY).

I remember you can use too the weapon attachment with the player id and TE_BEAMENTS for example. ( eg : id | 0x2000 )

Anyway I'm going to do some research on it, long time i wanted to do this weapon.

[edit] Btw, you can do it without orpheu.
