Refactor: Carp Infusion & Lungs (#71940)
## About The Pull Request Recently before merging PR #71867 I failed to account for the carp lungs and spacewalk trait in my testing (I did not try to fly across space) and so I did not notice other bugs. This PR fixes the bugs/oversights which I missed in my prior PR. Fixes #72678 I have completed a refactor of `/obj/item/organ/internal/lungs/proc/check_breath` and `/mob/living/carbon/proc/check_breath` because I noticed that bugs within the gas alert system (stuck alerts) were caused by their improper execution, and the code was written in a hard-to-understand style. This PR also includes a small adjustment to status indicators which allows you to add an already existing timed indicator without overwriting it; it instead resets the existing timeout. Here is a granular list of bugs: - Bug A: Causes the spacewalk trait to not be applied to the mob, and is caused by a minor developer oversight in `/datum/status_effect/organ_set_bonus/carp/enable_bonus()` wherein it attempts to add `TRAIT_SPACEWALK` to the status effect rather than to the Mob. - Bug B: Causes the carp lungs to suffocate you in space, because that behavior is unimplemented. - Bug C: Causes the gas alert indicators ("Too much O2!" etc) to stay stuck to the screen if `check_breath` or other procs fail to remove them. This is caused by the way `check_breath` early-returns without executing the necessary logic to manage its gas alerts. - Bug D: The part of `lungs/proc/check_breath()` that removes consumed miasma from the air is only doing so when helium is also present and consumed. This PR contains fixes for these bugs: - Fix A: Added the spacewalk trait to the mob, allowing the trait to enable space flight as expected. - Fix B: Added `TRAIT_SPACEBREATHING` as a lungs trait, which is used in `check_breath`, which allows the mob to "breathe" in space or vacuum, but suffocate when breathing unsuitable gas/O2. - Fix C: Changed the proc `/mob/proc/throw_alert` such that, when throwing an alert which already exists, it resets the timeout of the existing alert rather than replacing it. - ~Fix C2: Added a 10 second timer to gas alerts. If something fails to clear them from the screen, they will now clear themselves after 10 seconds.~ - Fix D: Refactored `/mob/living/carbon/proc/check_breath` and `obj/item/organ/internal/lungs/proc/check_breath` to run the necessary logic for resetting gas side effects and gas alerts. - Removed an early-return which was causing the `check_breath` functions to skip most of their critical sections. - Fixed the part of `lungs/proc/check_breath()` that removes consumed miasma from the air, allowing it to remove the correct amount when expected to. - Added conditionals to check for `TRAIT_SPACEBREATHING` on lungs to bypass suffocation. - Added a fall-back to a default "flyweight" breath `datum/gas_mixture/empty_breath` to Carbons and lungs, used in in the event that either gets a null `breath`. - Renamed `obj/item/organ/internal/lungs/proc/handle_too_little_breath` to `handle_suffocation` and refactored it to handle more aspects of suffocation that was originally being handled inline. - Added `/obj/item/organ/internal/lungs/proc/breathe_gas_volume` to `check_breath` to replace lots of inlined logic which handles consuming/exchanging gases (O2 for CO2, etc). ## Why It's Good For The Game Shortly after PR #71867 was merged, we noticed the carp lungs and spacewalking trait were not working as expected when doing the Space Carp DNA infusion. This PR fixes the bug and allows you to spacewalk like a Space Carp again. This PR also adjusts the gas alert indicators so they don't get stuck to the screen as often. This PR also fixes a bug that was causing timed alerts to overwrite each other when it was unnecessary to do so, and helps prevent their on-throw animation from being replayed when not appropriate. I have included an intermediate refactor of `/mob/living/carbon/proc/check_breath` and `obj/item/organ/internal/lungs/proc/check_breath` in this PR, and I have tried to improve readability/maintainability while correcting critical oversights in the ways breathing was working. After my changes are merged, I will likely work on another refactor to delete duplicated sections of code between Carbons and lungs, as much of it is 99% identical. ## Changelog 🆑 A.C.M.O. refactor: Refactored breathing, mostly check_breath, for Carbons and lungs organ. add: Added the space-breathing trait for lungs. fix: Fixed the Space Carp DNA infusion to apply the Spacewalk trait, allowing you to fly through space. fix: Fixed the Space Carp lungs, allowing you to breathe in space with them. fix: Fixed gas status indicators re-playing their on-throw animation when they are refreshed. fix: Fixed gas status indicators getting stuck to the screen in some situations. fix: Fixed gas side effects, such as euphoria and hallucinations, to reset when expected. fix: For Humans, fixed Miasma only being consumed from the air when Helium is present. /🆑 --------- Co-authored-by: Jeremiah <42397676+jlsnow301@users.noreply.github.com> Co-authored-by: LemonInTheDark <58055496+LemonInTheDark@users.noreply.github.com>
