I think just about everything from the old thread has been implemented in some way or another. Time to make a new thread to gather ideas. Stuff that hasn't been implemented from the old thread to the best of my knowledge: "ammo_fuse": Changing behavior when ammo lifetime runs out. "apply_effect_spec": Multiplying unit characteristics by values upon ammo hit. "splash_ally_multiplier": Changing splash damage done to allies. "fire_in_transport": Making certain units be able to fire in transports. See Raevn's suggestion below as well. "can_res_wreckage": Allowing units to resurrect wreckage. "assist_units" and "unassistable": More fine tuned controls on assist building. "impacts_on_water_surface": Fixing the "sea_floor" target layer "splash_damages_self": Splash damage that doesn't affect the unit of origin. And now for a new request: Suggested Flag: "build_bar_tabs" Normal Location: In the json of any fabrication unit or factory. Variables accepted: An array of strings. Default variable: Not applicable. Prerequisites: none Expected Behaviour: Makes the unit only load specific build bar tabs into its build bar UI. Example: In unit_cannon "build_bar_tabs": [ "unit_cannon" ], The unit cannon will now only use the "unit_cannon" build bar tab, which, if properly defined in build.js, would have all of the unit cannon buildable units organized in a single tab.
