* Adds defines for world.tick_usage
* This provides no useful benefit whatsoever, but /tg and Baystation12 have done it, so it will make porting future code easier if we do too. No real harm done either.
Mostly ports /tg/'s method of seeding submaps into specific z-levels.
Due to the low number of submaps present, all of the PoIs are guaranteed to spawn. As more are added, this should fix itself.
Ported 'see-down' open spaces from Vore, who ported it from Eris
Ported talking and visible messages traveling upwards through open spaces
Tested, seems to work? Does not seem to break anything, maybe.
Maybe made a changelog.
New lighting system is needed to handle updating literally 14k+ tiles whenever the sun moves. The straight port seems to have had no adverse effects from what I could see. Don't know if it's more performant but it doesn't seem to be less.
I didn't expect the latter would be needed for the former.
Pink Slime Aura and Mend Synthetic (technomancer) should now fix FBPs again.
Adds procs to get the 'real' number of damage from humans, including limb damage on prosthetic limbs.
Slime following made a bit more robust, slimes (and other simple animals) stop wandering when following.
Slimes following a leader that passes the can_command() check will refrain from attacking things if not attacked first.
Slime kill command implemented, requires the slime to be in your faction or be the slime's friend, and not just obedient. This can be accomplished with end-game slime agents.
Slimes require three 'free' tiles to split, which should prevent super overcrowed cells and by extension avoid Amber Tide from crashing the mob controller.
Dark Blue Cold Aura now properly adjusts temperature based on protection gradually instead of instantly setting to the lowest value.
Adds toolspeed var, which is a multiplier on how 'fast' the tool works. 0.5 means it goes twice as fast.
Adds usesound var, which determines what sound is used when a tool is being used.
Changes a lot of code to use those two vars instead.
Adds 'ayyy' tools, which are ported from /tg/'s abductor gamemode. They're currently admin only but I might make them obtainable by xenoarch later.
Adds powertools, also from /tg/. CE starts with them in a new toolbelt that spawns in their locker, ported from (you guessed it) /tg/.
Changes welder sprites to look nicer, ported yet again from /tg/. Modified the blue welder slightly so it can be the electric welder sprite.
Adds various sounds from /tg/, for tools and welders.
Southern Cross shuttles one and two can now launch.
Adds missing areas for shuttles 1 and 2.
Shuttles warming up, moving, or stopping now make a nice sound, ported from /tg/.
Rearranges shuttle datum/computer definitions to make it easier to read.
Removes cloaking abilities for most multi-shuttles.
Lowers transit time for multi-shuttles. Can be raised later if desired.
* Based on https://github.com/tgstation/tgstation/pull/25386
* Create macro for defining new subsystem types.
* Create PreInit proc to handle setup that needs to be done before the map loads
* Rename garbage_controller subsystem to garbage so it matches its global SSgarbage variable name.
* Settings for specific z-levels are defined in datum types, allowing the lists of Z levels to be automatically configured. This solves the problem of being unable to use the z-level #defines in associative lists.
* Converted the example and northern star maps to use the new system.
