Alright - Sorry guys but yeah this mod is no longer going to be touched by me. I know I promised a lot (sorry again) but I'm focused on other things, about to go to college and I unfortunately have completely lost interest. However I'm willing to share the project for anyone to work on or just play with. Here
's a link to download the project, I was using version 4.0.0f7 of Unity when working on it. It's up to 1 day before the most recent release on this forum.
About the tutorial to add weapons, I put that off because explaining it is kind of a pain (probably needs a screen recording & voice over or a huge amount of text), it's pretty simple but I haven't felt like taking the time to remember how to do it (I haven't looked at the project in over a year). Just take a look at the prefabs for the weapons and try to notice the pattern between names of gameobjects and their positions/rotations (names of certain objects are required to be said names and get used for poses), or rather check the code for the action-specific names. Things like 'point_slide_pull' is the position the slide should be at when fully pulled back. Moving that object will adjust where the slide gets pulled to. Then look at the object named 'weapon_holder' or something that contains the prefabs for the guns that were added.
If you download the project feel free to take over and post it as your own, with or without credit. Or just take the models from it to use (Some models ripped from Red Orchestra 2 so best not to take those for your own non-Receiver project). Be warned that some code I've added may not be the cleanest, at the time I was still at a fairly basic level of programming, I know a lot more today than I did back then but I still have a long way to go. I wonder if I left any funny comments in there... I didn't bother to look at it at all before I started uploading it. Also, you'll find that there are a few weapon models in there that I didn't get around to setting up, one being the MKB-42 which you could find resting on a table in the range. Maybe someone else can set them up.
