Please refer to #20867 and #20870 for a easier view of the changes. Those two PRs show all meaningful changes (hopefully) and doesn't show the files changed with just 3 lines changed.
This PR does three things:
It makes all children of /obj/ use the same damage system.
Previously to make your new machine/structure be destroyable you needed to give it a var/health, and its own version of many damage related proc such as bullet_act(), take_damage(), attacked_by(), attack_animal(), attack_hulk(), ex_act(), etc... But now, all /obj/ use the same version of those procs at the /obj/ level in code/game/obj_defense.dm. All these obj share the same necessary vars: obj_integrity (health), max_integrity, integrity_failure (optional, below that health level failure happens), and the armor list var which was previously only for items, as well as the resistance_flags bitfield. When you want your new object to be destroyable, you only have to give it a value for those vars and maybe override one proc if you want a special behavior but that's it. This reorganization removes a lot of copypasta (most bullet_act() version for each obj were nearly identical). Two new elements are added to the armor list var: fire and acid armor values.
How much damage an obj take depends on the armor value for each damage category. But some objects are INDESTRUCTIBLE and simply never take any damage no matter the type.
The armor categories are:
-melee(punches, item attacks, xeno/animal/hulk attacks, blob attacks, thrown weapons)
-bullet
-laser
-energy (used by projectiles like ionrifle, taser, and also by EMPs)
-bio (unused for this, only here because clothes use them when worn)
-rad (same)
-bomb (self-explanatory)
-fire (for fire damage, not for heat damage though)
-acid
For machines and structures, when their health reaches zero the object is not just deleted but gets somewhat forcedeconstructed (the proc used is shared with the actual deconstruction system) which can drops things. To not frustrates players most of these objects drop most of the elements necessary to rebuild them (think window dropping shards). Machines drop a machine frame and all components for example (but the frame can then be itself smashed to pieces).
For clothes, when they are damaged, they get a "damaged" overlay, which can also be seen when worn, similar to the "bloody" overlay.
It refactors acid. See #20537.
Some objects are ACID_PROOF and take no damage from acid, while others take varying amounts
of damage depending on their acid armor value. Some objects are even UNACIDABLE, no acid effect can even land on them. Acid on objects can be washed off using water.
It changes some aspect of damage from fires.
All /obj/ can now take fire damage and be flammable, instead of just items. And instead of having just FLAMMABLE objs that become ON_FIRE as soon as some fire touch them (paper), we now have objects that are non flammable but do take damage from fire and become ashes if their health reaches zero (only for items). The damage taken varies depending on the obj's fire armor value and total health. There's also still obj and items that are FIRE_PROOF (although some might still be melted by lava if they're not LAVA_PROOF).
When a mob is on fire, its clothes now take fire damage and can turn to ashes. Similarly, when a mob takes melee damages, its clothes gets damaged a bit and can turn to shreds. You can repair clothes with cloth that is produceable by botany's biogenerator.
It also does many minor things:
Clicking a structure/machine with an item on help intent never results in an attack (so you don't destroy a structure while trying to figure out which tool to use).
I moved a lot of objects away from /obj/effect, it should only be used for visual effects, decals and stuff, not for things you can hit and destroy.
I tweaked a bit how clothes shredding from bombs work.
I made a machine or structure un/anchorable with the wrench, I don't remember which object...
Since I changed the meaning of the FIRE_PROOF bitflag to actually mean fire immune, I'm buffing the slime extract that you apply on items to make them fire proof. well now they're really 100% fire proof!
animals with environment_smash = 1 no longer one-hit destroy tables and stuff, we give them a decent obj_damage value so they can destroy most obj relatively fast depending on the animal.
Probably a million things I forgot.
If you want to know how the damage system works all you need is the three obj vars "obj_integrity", "max_integrity", "integrity_failure", as well as the armor list var and the resistance_flags bitfield, and read the file obj_defense.dm
Adds a large ash and large molten item decal (for future use)
simplifies decal/cleanable/replace_decal() code a bit.
Changes construction() proc to on_construction() for consistency, same for deconstruction().
Made a deconstruct() proc for machinery and computer (also for future use).
Added priority overlays to atoms, which will not be removed when overlays are cut and will always remain on top when new overlays are added. This requires everyone to use add_overlay() and cut_overlays() instead of overlays += and overlays.Cut(). These procs are found in __HELPERS/icons.dm, and the priority overlay list is found in game/atoms.dm. Everything else is replacing deprecated overlay manipulation.
Blood drips icons are now in blood.dmi instead of drip.dmi (which only had the 5 drip sprites).
Moved projectiles, guns, casings and ammo boxes to be in the right files. Please don't put your gun with its projectile, ammo casing and ammo box all the same file.
I split growing.dmi into 5 smaller files so we don't get close to the 512 icon limit again. Each seed has a var to indicate which icon file to use when planted.
Fixes code for heavy pulse laser projectile to be less awful.
You can now remove all plants and weeds from a hydroponics tray by using a spade on it. This process takes five seconds.
Hydroponics trays now have a unique variable, using_irrigation, that replaces the previous iteration of irrigation hoses that used the anchored variable to track it instead.
Fixes a possible runtime error that can occur when using irrigation hoses to transfer non-water reagents (specifically nutrients, although it hasn't been tested with any other reagents).
Added meatwheat, which is mutated from normal wheat plants. It's essentially a blood-red version of wheat that can be crushed into a meat slab by activating it with an empty hand. These meatwheat clumps are slightly bloodier than normal meat, but it still works for recipes that use normal meat slabs.
Added ambrosia gaia, which is mutated from ambrosia deus. It's yellow, glows brightly, and contains only earthsblood (renamed adminordrazine). The plant is destroyed after a single harvest, and its product can be planted in an empty hydroponics tray to cause it to become self-sufficient, no longer requiring nutrients, water, or weed/pest removal. Gaia-blessed trays will glow bright yellow in comparison to normal trays, and gaia-blessed soil will turn yellow. Both will emit light.
Added cherry bombs, which are mutated from blue cherries. They're orange and have a black stem, and start with a tiny amount of black powder in them. Activating them in an empty hand will ignite them and cause them to explode after three seconds, with explosion strength varying based on potency (at the most, it's around that of a minibomb).
These are the files with just tiny tweaks. Mostly modify an object's attackby so it does "return ..()" instead of "..()".
If there are other things in this commit, the PR's description will explain them.
Beeboxes have honey_frames which determine the amount of honeycomb+bees they can maintain.
Bees now have a beegent (Bee reagent, geddit?) that they use during their attacks AND that their produced honeycomb contains, this allows you to farm chemicals using bees.
spawns have a high overhead.
I only went for easy targets, almost every spawn could be removed with a few subsystems in place to handle delays or cooldowns
Fixes a runtime with two blob reagents.
Fixes a reference not being removed when hydro tray is destroyed.
Laser pointer can no longer weaken AIs (no eyes).
Plantpeople are just podpeople without the "healing in light" mechanic. I believe they were originally included in case someone wanted to develop them into a roundstart race, but since no one's done that they've just been doing two things in the code:
1. Tricking wizards who use the magic mirror into picking plant over pod and then getting confused why they aren't healing.
2. Making turning into a plant based human slightly too likely in the staff of change.
