If you want....since this will give you a rather nice start for this, I can give you what I have when I started working on a similar mod way back a couple years ago. I never released the code to anyone and more then willing to let you use it for your mod. You don't even have to credit me for it since it was mostly test code I was messing around with while trying to figure some of the lua internals out for the game...since a local multiplayer is of no real use to me personally. Tho, here is a tip for you and an offer if you decide to take this up....
Since the Bully Multiplayer team has no intentions at this time to incorporate full coop play or ai...etc into their mod for online play...maybe WE as in the BB modders can all team up and add to this project and maybe even help you out a little bit with it. This would be a great exercise for everyone on practicing REAL teamwork together and come up with something we all can be proud of being part of.
We could all chip in little bits to make the local multiplayer fully able to do coop play so that if say one of you has a friend or two over at your house ....then you could fire Bully up and play through the entire game in a full coop mode that works. Mind you...there would be a couple minor hurdles to overcome such as proper usage of cameras so that it would be more usable due to no actual splitscreen mode...least not that I ever found yet.....and go from there. Then you would have a seriously unique mod to be proud of doing work on.
You don't have to do this....it is just a cool suggestion for you to think over since...while I am technically retired from all modding....I am more then willing to still do a few mods here and there.
Oh and btw, DaBOSS and I resurrected the PSMM mod and we will be finishing that off fully for everyone. We already have complete ide bypass working for all peds including player (minus a couple hiccups) and I am trying right now to get time to add to the project and code up some other things that will be needed for this to be fully working. Trying to go for a full game integration so this will not break anything in the game and allow you to play through the entire game without having anything break on you. DaBOSS and I will explain all of that in a seperate thread as soon as we feel the time is right.
