<!-- Guidelines: https://docs.macrocosm.cool/docs/intro --> ## About the PR This PR ports the Detritivore trait from TheDenSS14/TheDen#684. Entities with a detritivorous diet can derive hunger from gastrotoxin, mold, vent crud, and reprocessed material (trash) without being poisoned. In addition, reprocessed material was given a *new* poison metabolism for non-Vox/non-Detritivores. ## Why / Balance Required for these PRs: - #115 - #62 ## Technical details `AddMetabolizerTrait` is a new trait function that adds metabolizerTypes to all metabolizing organs of an entity that pass a certain whitelist. (You can, for example, make it *only* affect the heart or lungs, or whatever). This sends an event to the extended `MetabolismSystem` to add or remove metabolizers respectively when the trait is added/removed. Detritivore trait adds the "Detritivore" type to all metabolizing organs. A new set of organs with both "Detritivore" and "Animal" metabolisms were added. This was given to rats (like the Rat King) and mice. The following metabolisms were added: - Detritivores are not poisoned by gastrotoxin and sate hunger from it at 0.5x rate. - Detritivores are not poisoned by mold and sate hunger from it at 0.5x rate. - Detritivores are not poisoned by vent crud and sate hunger from it at 0.25x rate. - Detritivores sate hunger from reprocessed material at 0.25x rate. Non-vox and non-Detritivores take 2 poison damage per 0.5 unit of reprocessed trash. - Detritivores are not poisoned by uncooked proteins, and can derive hunger from it, similar to animals. I'll deal with trait balance later ## Test plan <!-- Describe how you tested the pull request, and how someone reviewing this PR can test it themselves. --> - Pick the "Detritivore" trait in character editor and spawn in - Eat rotten meat, moldy bread, maybe sip on reprocessed material (trash) and vent crud. Should not poison you. - Do the same to an unmodified non-Vox urist - they should be poisoned. - While you're at it, remove the trait from yourself with `self traits:remove Detritivore` and try guzzling trash and mold again. You should be made horribly sick. - Mice and rat kings should have the Detritivore diet. ## Media <!-- Attach media if the PR makes in-game changes (clothing, items, features, etc). --> <img width="672" height="84" alt="image" src="https://github.com/user-attachments/assets/98b4fa82-632f-43b4-81d6-73822329e613" /> ill handle trait balance later ### Metabolisms <img width="658" height="305" alt="image" src="https://github.com/user-attachments/assets/3fd8a5fb-10d3-42ea-bdff-835d5c0cedb7" /> <img width="652" height="253" alt="image" src="https://github.com/user-attachments/assets/506698c5-1dc3-4d3d-8ff6-0e053debe2a8" /> <img width="656" height="374" alt="image" src="https://github.com/user-attachments/assets/85ea3154-6acd-438c-abf7-748b9c9e714c" /> <img width="658" height="229" alt="image" src="https://github.com/user-attachments/assets/59b231aa-a2e2-450b-9e13-a2b0b02ba394" /> <img width="654" height="367" alt="image" src="https://github.com/user-attachments/assets/678fcead-f05a-4be6-925f-b064d2cf744c" /> ### Gameplay Injecting 15u gastrotoxin each into detritivore and non-detritivore reptilian <img width="923" height="611" alt="image" src="https://github.com/user-attachments/assets/b85f7ded-3f51-4142-8775-9fdd9531088e" /> Removing detritivore trait from self and injecting 15u gastrotoxin <img width="638" height="75" alt="image" src="https://github.com/user-attachments/assets/5ceb0af1-2ebe-4150-b091-e785db2e90cc" /> <img width="558" height="540" alt="image" src="https://github.com/user-attachments/assets/0284c997-c9b5-4297-af11-2be91e93c1e6" /> ## Requirements <!-- Confirm the following by placing an X in the brackets without spaces inside (for example: [X] ): --> - [x] I have read and am following the Macrocosm [Pull Request Conventions](https://docs.macrocosm.cool/docs/Conventions/pull-requests/). - [x] I have tested this pull request and written instructions on how to test it. - [x] I have added media to this PR or it does not require an in-game showcase. <!-- You should understand that not following the above may get your PR closed at maintainer’s discretion --> ### Licensing <!-- This is REQUIRED for any code submitted to The Den 2 repository. If this is a port, make sure to check the original repository's license! This code can be licensed to MIT if: 1. You wrote it yourself, and you agree it can be MIT-licensed. 2. The original pull request originates from an MIT-licensed codebase, such as Wizard's Den. 3. The original code author submitted the code to a non-MIT (e.g. AGPLv3) codebase, but has given explicit permission to have their code re-licensed. If your code does not fit these cases, it probably can't be accepted! If you need help getting MIT licensing, please ask for help in our development channels. --> - [x] All code in this pull request can be licensed to MIT. <!-- Macrocosm is The Den 2's upstream repository. We may port features to Macrocosm if other servers that share the Macrocosm upstream are interested in the feature. --> - [x] (OPTIONAL) I give permission to seeing this feature upstreamed to Macrocosm in the future. ## Breaking changes <!-- List any breaking changes, including namespaces, public class/method/field changes, prototype renames; and provide instructions for fixing them. Also, include instructions on how to enable/disable the content for the benefit of downstreams.--> mice have a `BaseMobDetritivore` parent that changes their organs `BaseMobRat` also had its organs changed these mobs will be unusable for "animal organ"-type recipes specifically ## Changelog <!-- Add a Changelog entry to make players aware of new features or changes that could affect gameplay. Make sure to read the guidelines and take this Changelog template out of the comment block in order for it to show up. Changelog must have a 🆑 symbol, so the bot recognizes the changes and adds them to the game's changelog. The name that appears on the changelog will be your GitHub username by default. If you wish for a different name to appear, format the symbol like so: 🆑 My Name --> 🆑 - add: You can select the "Detritivore" trait in the character editor to be able to consume gastrotoxin, mold, reprocessed material (trash), and vent crud safely. - add: Reprocessed material (trash) is now poisonous to non-Vox and non-Detritivores. - add: Mice and rats are now detritivores.
