Well it's pretty much a fan that blocks/absorbs air currents instead of the usual "blocks/absorbs particles" or a regular fan. I could see it useful, but hard to code.
PStech14 My reason? Would it be worth the work. Yeah it's cool and might be useful, but, not many people have wall coding experience and it could get a bit confusing. And theres a chance that we'll make the game crash due to an unknown error. I just don't think its worth the effort. If someone with wall coding experience could do it great! If not, I wasn't expecting it done.
Edit: pilojo and yew101's acct. Were sharing cause were making a mod together.
Alright that makes more sense. I have absolutely no experience coding or making games so i guess i dont understand the effort invovled but if possible i think it could be very useful.
