Well I haven't seen Player saying anything about that on 100% confirmed Accounts and IRC isn't reliable at all. Also note that I have seen some fake KingLemming Accounts on less known Forums in the past too (That's one of the Reasons I have a List of used Accounts in my Profile, which consists out of Youtube, IC-Forum and MC-Forum). I even saw a fake "GregoriusT" account on an IRC Log (even though that was an obvious alias change).
Also a Jetpack by itself has to do just one thing: Changing the Y-Velocity within the Armor Tick Callback when the Steve holds down the Jump Button. That is all a Jetpack should have to do, and the Energy Cost thing is a Part of TE itself (what is basically a ripoff of the IC2 Charging System)
And what the fuck is bad about stealing small Parts of someones Code? It is not like stealing all the Code and releasing the same copied thing as new Mod, and I have seen other people do that on this very Forum. Not to mention that this is all Mod Code and not productive (aka Money relevant) Code.
This shit is getting ridiculous (and it has been ridiculous in the past). Guess why I usually don't even try to communicate with other Modders unless there is a Question or something. Large groups of people talking to each other always leads into bullshit (see Democracy), and the whole Internet is evidence for that, especially if everyone wants attention from "the Audience" aka Direwolfs Fans and Modpack Users.
I think that is all I wanted to say about this stupid Situation, and now I have to finish up the Granite Worldgen before I can release a shitty Open-Alpha-Version of GregTech, like every Game Dev does recently.
