I also work on something like this sort of, i have maked a Saber System for my own OpenJK version. i have a cool block box in it and a block button there activated when a make a saber swing or when a incoming attack comes in to the player so he can defend himself, i have saber damage scale also there can be edit in the server.cfg, got trueview, Movie Saber types of the blade, rgb sabers and sfx sabers, Saber block lightning, and my awesome hud . my main goal for this mod was to keep the old ways of JKA combat like jump around do cool moves combos and still have mblock as a sec defence thing and it works really good, i don't want any sort of Block point in this so i keep that out from the code if you want to have a look at this afinity you can pm me and come on my server and try it out, then i'll send you the client files for it and if you like you can always take a look at the code i have done some edit in to
