Alright, it's been way overdue and I know you guys have been expecting updates and whatnot from me. I'm sorry to disappoint as I've let you down. I'm just going to give a somewhat brief summary of what's going on.
Basically, I'm working on this add-on by myself. I've had some other developers that I've contacted assist me briefly but they've been caught up with their own stuff. One of the assistant developers doesn't seem to want to search the add-on files for lines I've prefixed "TODO" in the repository, so it just adds extra stress on me because I'm somewhat expected to copy paste the code chunk or explicitly throw them a link to the code that's yet to be implemented. I'm not shaming anyone, but the current setup is a mess and I'm going to address that.
As for the add-on itself, the base files are designed around UCC 2.1.7 and have only just recently been updated to 2.1.9 and the latest PUN2 version. I have also been needing to get in touch with Justin as there's a lot of code in the hot path that can possibly be taken out benefiting his PUN add-on as well as mine, but if he doesn't want to, that's his choice. I'll try to optimize the network add-on to avoid any burns on the code hot paths. UCC 2.1.9 has changed a bunch of stuff in the network layer and I need to update the add-on code to handle that. That said though, I don't think I'll have the add-on ready in time for UCC 2.2, so you'll be stuck on the version below the latest and greatest (oldstable).
Fully server authorizing UCC is pretty much going to be asking the impossible. There's a lot of stuff in there that has to be adapted to a server authorative system. So the add-on will be a hybrid, some parts client authoritative, but some essentials will be server authoritative. The PUN add-on code that I'm reading, interpreting, and then writing my own implementation for Mirror.
If you've seen my YouTube videos, I've already got a working prototype of UCC on Mirror architecture running. However, one problem there is that some abilities aren't being started (ie. HeightChange still throws errors) when players spawn. The animator works alright and things correctly get set using NetworkAnimator, but abilities seem to be special. I'll be looking into that.
There's also IRL shit that I've gotta sort out before I get back to developing this add-on. That includes sorting out business accounting (which I will not discuss here), dealing with clients' drama (protip: stay away from overseas web design firms, they are the worst), being effectively immobilized because I damaged my transport (tree stumps, oil pump and sump pump. What a wonderful combo) and other programming contract work.
I am falling behind the 8 ball a lot recently and it's been a mad scramble to keep afloat - as well as back to back IT support call outs. This add-on was one of the many thing that's fallen on the backburner.
So, if you made it this far, I appreciate your patience. I am slowly getting back up to speed. Things should get better from here. I hope to have progress to show in the next week or two.
