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
This just adds some vars that the refactor will use. Putting this in a separate PR prevent the damage refactor PR from becoming too big (number of files changed) and hard to read and review.
Introduces the resistance_flags bitflag that replaces unacidable and burn_state.
Moves the armor var from item to /obj level and gives specific armor values to many objects, the armor list also gets two new armor types: fire and acid, which will be used in the refactor. the new fire and acid armor values are given to plenty of items.
* - I rearranged X_defense.dm mob files, more damage_procs.dm.Here's what's inside:
* X_defense.dm: is for the procs of attacks onto the mob, all the XXX_act() proc (things happening to the mob), as well as protection check and get procs (armor, ear prot, projectile dismemberment)
* damage_procs.dm: actual damage procs like adjustBruteLoss() getfireloss, any proc that handles damaging.
- some bugfixes with gibspawner effects.
- monkey's bodyparts can be dismembered and are used to create its icon.
- brains are no longer carbons.
- all carbon have bodyparts that can be dropped when the mob is gibbed.
- adminspawned bodyparts now have a default icon.
- robotic parts are now a child of bodyparts.
- health analyzer on alien/monkey shows damage on each limb
- added admin option to add/remove bodyparts for all carbon (instead of just remove on humans)
- Fixes keycheck message spam for janicart and all when trying to move.
- Fixes bug with buckling to a scooter while limbless.
- removed arg "hit_zone" in proj's on_hit() because we can already use the def_zone var (where hit_zone got its value)
- Fixes mob not getting any damage when hit by a projectile on their missing limb, despite a hit message shown). carbon/apply_damage() now when we specify a def_zone and the corresponding BP is missing we default to the chest instead of stopping the proc. Consistently with how human/attacked_by() default to its attack to chest if missing limb.
- Fixes mini uzi icon when empty and no mag (typo).
- I renamed and changed a bit check_eye_prot and ear prot
- renamed flash_eyes to flash_act()
- I made a soundbang_act() similar to flash_act but for loud bangs.
- added a gib and dust animation to larva.
- husked monkeys
- no damage overlay for husk or skeleton.
- damage overlay for robotic limb now.
- no damage overlay when organic bodypart husked.
- one handed human with a bloody hand still get a bloody single hand overlay.
- fix admin heal being unable to heal robotic bodyparts.
- slightly touched robotic bodypart sprites (head one pixel too high)
- Fixes 18532 "beheaded husk has hair".
- Fixes 18584 "Ling stasis appearance bug"
- no more eyes or lipstick on husks.
- can remove flashes/wires/cells from robot chest and head with crowbar.
- Fixes not being able to surgically amputate robotic arm/leg.
* More merge conflict fixes and adding the new files I forgot to add.
* of course I forgot birdstation
* More typos and stuff I forgot to undo.
* Fixing a typo in examine.dm
Removing an unnecessary check.
Making admin heal regenerate limbs on all carbons.
Monkey-human transformation now transfer missing limbs info and presence of a cavity implant.
NODISMEMBER species can still lack a limb if the mob lacked a limb and changed into that new species.
Changeling Regenerate ability now also regenerate limbs when in monkey form. (and remove some cryptic useless code)
* Fixing more conflicts with remie's multihands PR.
* Fixes runtime with hud when calling build_hand_slots().
Fixes lightgeist healing not working.
Fixes null.handle_fall() runtimes with pirate mobs.
Fixes typo in has_left_hadn() and has_right_hand().
* Derp, forgot to remove debug message.
* Xenomorph Tweaks
- Xenos are now considered female.
- (Nerf) Hunter pounce are now always blocked by shields, and may be
blocked more often by other protective items.
- (Buff) Alien Queen is 2 points faster.
- Adjusted larva growth sprites.
- Removed 20% facehugger failure chance for masks.
- (Tweak) Disarm now always forces a person to drop an item in the
active hand, and if a person's hand is empty/undroppable, Disarm will
always result in a tackle.
- (Nerf) Borgs are no longer stunned by Xeno disarms.
- (Buff) Tail Sweep now has a slightly longer stun.
* Teaks and Fixes
- Pouncing is now a LEAP_ATTACK, and is now ALWAYS blocked by shields.
- Changed Disarm combat for borgs: First disarm strike disables the
borg's active module. The second strike pushes the borg back and stuns
it.
* Mini Fix
* Get that one too
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.
Also removed some mob vars like sdisabilities and merged the usability
with disabilities
Removed need for mutations var, they are not handled in dna
Removed blinded var, now its handled by eye_blind being bigger than zero
Ands lots, lots of other shit in files that used mutations
Weapons that do no damage play a tap sound, except for the bike horn and banhammer.
Adds a different attack message for forceless attacks. It says tapped or
patted on instead of attacked in.
Adds force zero check to armour before attempting to block attacks.
Adds hitsounds to the welder, lighter, matches, cigarettes, energy sword and energy axe for when they're on and off.
Adds 5 force to the lighter when it's lit. Same as when you accidentally burn yourself lighting it. Adds a hitsound and the correct damage type to the lighter.
Adds hitsound volume scaling based on the weapon's force and its weight class. Adds tap sound scaling based on a weapon's weight class.
Removes boldness from item attack messages on non-human mobs. The attack is still bolded for the player
controlling the mob.
Adds a force check to blood spurts when attacking non-human mobs. If the weapon doesn't have a force, no blood will come out.
Adds adminhelp.ogg as the banhammer's hitsound with Cheridan's permission.
Adds a much needed period to the catatonic human examine message.
Makes the activation and deactivation sounds of toy swords, energy swords and energy shields quieter. What an earsore.
Makes description, item_state and name of matches that have burned out on their own consistent with those put out by the player. Changes match, cigarette and lighter attack verbs and forces based on whether they're lit or not.
Fixes a bug that allowed players to light cigarettes with burnt matches.
Names lit cigarettes and children of cigarettes lit [name].
Fixes a bug with the energy blade that kept it at weight class 5 after it was deactivated.
Changes the welder out of fuel message slightly to be less fragmented.
Removes dead air from most of the weapon sound effects used in this pull to make them more responsive. In other words, the fire extinguisher sound will play a lot sooner after you click than before. Equalised their peak volumes to all be -0.1dB and in an attempt to make altering volumes based on force more consistent.
Thank you @YotaXP for help with the item_attack.dm attack messages.
Thank you @optimumtact for help with code for testing item_attack volumes.
Thank you @Giacom for help with the code for scaling hitsound and tap sound volume by hitforce.
Thank you @Tastyfish for telling me why my proc wasn't working.
Thank you to anyone else on #coderbus who helped me who I've forgotten to mention.
Conflicts:
code/game/objects/items/weapons/shields.dm
code/modules/events/ninja.dm
code/modules/mob/living/carbon/human/update_icons.dm
No more cloakers, no more cloak_stacks. Also removed that silly "I'll make an icon and then make an image of that icon" bullshit.
Changed all the hair/facial_hair/eye sprites to use a white base.
Changed the preview screen, in the preference menu, to use ICON_MULTIPLY to be able to use the new white sprites.
Removed the unused and broken cloaking item.
Ninjas now use the alpha variable, removed most of the checks for it.
Updated the documentation a bit.
Added some helper procs for later.
*TABLEPASS was already totally obsolete.
FPRINT was used, but it was on virtually everything anyway.
Removes those flags from every instance where they were used. Also assigned and removed other flags where it made sense.
If it is desired, I can revive the flag as NOFPRINT, which would retain the original functionality, though inverted. That way it would be be used only where it was intentional (holodeck items could use this for example).
Cloakers still don't work well. The fix is probably just finding a proc that runs on equip/uequip/when bagged/when dropped. Fuck that. Ninjas work. Things that are cloaked fade to the cloaked alpha, it's pretty cool.
The "lying down" icon_states for everything you could equip are all now unnecessary. They aren't removed yet though.
The dmi changes are to make xenos all face upward so when they turn, they're lying down rather than facing south and looking like they're doing a handstand. They're not terribly good when facing the wrong way. I expect WJohnson to have a fix for this by New Year's.
Comments aren't changed. The overlays_standing list is still around because overlays is not a normal list, and BYOND's normal list functions are worth the extra cost of keeping a spare list of images.
Removed defines/obj/toy.dm and moved the defines down to objects/items/toys.dm
Moved a big chunk of defines out of defines/obj/weapon.dm and into their respective .dm files.
