Sorry, you will not be able to include the cloak, and no - wassup posted many many times that he wants poeple to piss off and stop pestering him.
however - i once posted a massive part about why the cloak won't work in SP, and also why it won't work in mods. To put it simply - it won't work in mods.
Let me repeat that again for you:
IT WON'T WORK IN MODS.
Okay - now you know, I wouldn't bother wasting my time. The reason for this is simply because in order for players to be able to utilise the cloak, they could also see the cloakers when they were cloaked........they appear normal. Infact - when u have a cloak - you cannot see or hear the effects of the cloak anymore.
Okay - now you know that. Put it into mod. For it to be used by poeple - it must be "activated", at which point they need it "turned on" in the files. This means that they can now see the cloaked ships as if they were normal ships, and can no longer seee the effects or hear it. So - therefore, if everyone has this..........what do you think happens?
Everyone can see the cloaks, no-one will see the effects, teh NPC's can see the players, oh dear, the cloak is now a pointless waste of time as it doesn't work! Doh!
I must admit, i used to chuckle away like mad as people used to say that cloaks would be in thier mods etc - heck nearly every mod that was being started etc said they would have it, but no-one thought of this very very obvious and simple problem. Silly really eh?
Oh well - there we go - cloaks can never be in a mod of large scale cause it will be useless. The only way it worked was cause some had it, and some didn't (the ones that didn't couldn't see it at all).
Oh - and finally - no, I won't, and nor will anyone else, be telling anyone how to make cloaks. And furthermore - Wassup did change his email addy cause poeple never respected his privacy and wishes. So don't bother trying to contact him either.
Anyways - good luck on the mod
