CBC Optics
Adds sights to Create Big Cannons, compatible with Aeronautics.
Main Additions:
- Cannon Sight: Attach it to the side of a big cannon and assemble the cannon. To view the sight either use one of the keybinds or use a sight viewer, to leave use a keybind.
- Autocannon Sight: Attach it to an autocannon, also compatible with cannons from Advanced Technologies and Neo Warfare. Works very similarly to a normal sight.
- Optics Control Unit: Used to manage multiple sights. Use a sight linker item to link sights to the OCU, shift right-click with the sight linker to reset it, then use a sight viewer to attach the OCU to yourself, you can then use the keybinds to control it.
Mod is still in beta so expect a couple bugs, so any bugs/suggestions/questions you find or have feel free to leave a comment, open up an issue on github, or even contact me directly via my discord @lememz
