HL3JB: S is progressing very slowly. I've got akimbo berettas in, as well as a manual pump shotgun (SPAS-12). The problem is that the HL2 player animation code is really crappy at best: whereas HL1 allowed you to have separate animations for the legs/torso, HL2 pretty much has one animation for both, which is really stupid. There's probably some way to code around this, but with school stuff going on progress has been slow.
I'm debating right now whether to release HL2JKS soon or to hold off until I get Snake Versus Monkey mode fixed. The problem with SvM is that it works, but it breaks when anyone leaves the server. Also, I still don't have permission from certain people to use their models, and so far, emails have been unanswered, which leads me to ethics question #2: should I go forward with the release or wait until somehow, miraculously I get permission?
You've done your part to get permissions. If someone is too lazy to say no or yes, then they obviously don't care. If you release and they whine about it, remove the model and say "about time you got off your lazy *** and answered me." You never claim "I made this model, it was all me" so I don't see why they'd get a chapped *** over it. You'd be in an ethical minefield if you just released without admitting that you're including the work of others, not if you've taken the steps necessary to give credit where it's due.
