GZ-Dregs & Chitin

by gz-mods

Biters now drop Chitin-bearing Shell Fragments. Process Shell Fragments into Chitin slurry, extract, and waste product that must be disposed of. Spoiled fragments will spawn biters nearby just as eggs do. Use Chitin to make durable and regenerative walls, unique equipment for fighting--or farming--modded biters, and consumables.

Version: 0.2.27
Date: 2026-09-29
  Integration:
    - Moved Collector Roboport prototype and runtime ownership to GZ Loot 1.1.22.

    - Added five 100-dose RPG adaptations: Chilling Aura, Regeneration, Adrenal Response, Steelskin, and Charm.
  Integration:
    - Chitin now registers its biological abilities and serum exposure triggers into GZ RPG's generic registry when RPG is installed.
    - Frost Gland prototype loot is removed from Frost Biters and re-distributed through GZ Loot while preserving Frost Biters' gland item and crafting chain.
    - Regenerative Serum consumes the GZ Tweaks Cactus Flower when that prototype is available.
    - Pheromone Serum and Charm use one shadow stealth force per player team, mirrored to the parent team's diplomacy while remaining in mutual cease-fire with the enemy force.
    - Existing saves that already researched Chitin Bio-Gel automatically enable newly available optional serum recipes after configuration changes.
  Graphics:
    - Added normalized 64x64 serum/material icons, 96x96 adaptation icons, and a 256x256 Chitin Bio-Gel technology icon.
Version: 0.2.23
Date: 2026-09-26

Date: 2026-09-25
  Features:
    - Added Stomper Shell Fragment drops through GZ-Loot.
    - Added Stomper Pheromone Gland recovery: 2 Stomper Shell Fragments -> 1 gland in the Chitin Crusher, unlocked by Biological Agents.

Version: 0.2.20
Date: 2026-09-25
  Compatibility:
    - Replaced separate GZ Chemistry/Pipeworks/Hazmat dependencies with GZ Hazardous Materials.
    - Updated toxic-protection calls and fluid-classification declarations to the GZ Hazardous Materials API.

Version: 0.2.19
Date: 2026-09-24
  Changes:
    - Toxic processing fumes now call GZ RPG's public Sprint-cancellation API while a player is exposed.
    - Sprint remains optional; Chitin behavior is unchanged when GZ RPG is not installed.
Version: 0.2.18
Date: 2026-09-24
  Integration:
    - Added optional GZ RPG 0.1.9 integration for toxic-processing exposure.
    - Registers a purple Toxic Exposure status effect with a skull-and-crossbones symbol.
    - The effect remains visible above the player for the same 30-second regeneration lockout and refreshes while exposure continues.
    - Toxic exposure gameplay remains functional when GZ RPG is not installed; only the shared status-effect presentation is omitted.
Version: 0.2.17
Date: 2026-09-24
  Features:
    - Added visual-only purple toxic processing fumes around active Chitin wet/acid processing.
    - Wet shell crushing, sulfuric separation, nitric-macerate resin processing, and oxidizing macerate now build toxic exposure on nearby players.
    - Toxic exposure gradually slows movement, up to 45% at maximum exposure, without directly damaging the player.
    - Entering toxic processing fumes disables passive health regeneration and Regenerative Body Mesh healing until the player has remained clear for 30 seconds.
    - Explicit capsule/fish healing remains usable during the regeneration lock.

Version: 0.2.16
Date: 2026-09-23
  Integration:
    - Added Gizmod as a required dependency.
    - Registers GZ Chitin with the Gizmod registry on initialization and configuration changes.
    - Advertises chitin processing, Toxic Spoilage, Body Mesh, Collector Roboport, and enemy-loot integration capabilities.
Version: 0.2.14
Date: 2026-09-20
  Features:
    - Toxic Spoilage now damages players carrying it at 0.02 HP per second per item.
    - Carried spoilage uses the dedicated toxic damage type when available, otherwise vanilla poison, so GZ-Hazmat and Toxic Body Mesh protection apply normally.
    - Main inventory, logistic trash, and cursor-held Toxic Spoilage all count as carried; stored or transported spoilage does not hurt players.
Version: 0.2.13
Date: 2026-09-20
  Compatibility:
    - Added optional dependencies for Toxic_biters, Cold_biters, and Explosive_biters so their enemy prototypes load before GZ-Chitin when installed.
Version: 0.2.12
Date: 2026-09-20
  Features:
    - Added Toxic Spoilage using the supplied biological-waste graphic.
    - Shell Fragments now spoil after 60 minutes into Toxic Spoilage instead of ordinary Spoilage.
    - Toxic Spoilage spoils after another 60 minutes and hatches one hostile biter: 70% Small Biter / 30% Medium Biter.
    - Toxic Spoilage uses a dedicated fuel category accepted only by the Space Age Heating Tower, allowing safe incineration without making it usable as ordinary fuel.
  Notes:
    - Toxic Spoilage has no burnt result; incineration destroys it completely.
Version: 0.2.11
Date: 2026-09-19
  Fixes:
    - Restored Shell Fragment spoilage: fragments now spoil into vanilla Spoilage after 60 minutes.
  Features:
    - Expanded the Collector Roboport custom GUI with mode, status, five 10-unit Spiderling Bay slots, load/unload controls, output counts, last-haul status, and an Output Hatch button.
    - Collector Spiderlings now stack to 10.
    - Spiderlings are stored in the Collector's internal 50-unit bay rather than mixed into the output hatch inventory.
    - Existing physical spiderlings found in collector hatch inventories are absorbed into the internal bay on update, up to the 50-unit cap.
Version: 0.2.10
Date: 2026-09-19
  Features:
    - Added a rudimentary 3x3 Collector Roboport, unlocked by Currency and Military 3 when GZ-Economy is installed.
    - Collector Roboports must be placed entirely on refined concrete.
    - Added Flux and Fragments collection modes with a 32-tile collection radius.
    - Added a 64-tile enemy safety radius; collectors retract underground while threatened and raise after 5 clear seconds.
    - Added Collector Spiderlings, with a maximum of 50 loaded per collector; first-pass dispatch is simulated and collection throughput scales with loaded spiderlings.
    - Added a persistent loading/output hatch that remains accessible while the main roboport is retracted.
  Integration:
    - Requires GZ-Loot 1.0.27 for direct retrieval of GZ-Loot enemy reward bags.
Version: 0.2.6
Date: 2026-09-19
  Changes:
    - Split Acid, Frost, Toxic, Fire, and Regenerative Body Meshes into individual technologies.
    - Acid/Frost/Toxic/Fire Body Mesh technologies require Military 3 and mirror its final science cost.
    - Regenerative Body Mesh requires Nuclear Science when available and consumes nuclear science packs.
    - Regenerative Body Mesh recipe now requires 1 uranium-235 in addition to 1 Chitin Membrane.
Version: 0.2.5
Date: 2026-09-19
  Features:
    - Added five 2x4 stackable Chitin Body Mesh equipment layers using the supplied full-body mesh art.
    - Acid, Frost, Toxic, and Fire meshes grant 10% resistance at Normal quality plus 2 percentage points per actual quality step.
    - Regenerative meshes restore 10% of maximum health per minute at Normal quality plus 2 percentage points per quality step.
    - Body Meshes may be mixed up to 10 total layers, with a maximum of 5 of any one type.
    - Quality scaling counts actual quality steps, so Legendary is 18% and GZ-Tweaks Mythical is 20% per layer.
    - Added Hazmat compatibility so poison/toxic protection cannot exceed 100% when Toxic Body Meshes are combined with Hazmat protection.
Version: 0.2.3
Date: 2026-09-19
  Changes:
    - Corrected the wet-processing chain so the Chitin Crusher produces Biter Dregs only.
    - Wet crushing is now 5 Shell Fragments + 20 Water -> 20 Biter Dregs.
    - Sulfuric separation is now 20 Biter Dregs + 20 Sulfuric Acid -> 1 Chitin Extract + 20 Sulfuric Macerate.
    - Chitin Membrane processing now uses the centrifuging category instead of generic chemistry.
    - Updated descriptions to make Biter Dregs the complete pre-separation biological feedstock rather than a leftover waste stream.
  Notes:
    - The existing Chitosan Resin branch remains 2 Chitin Extract + 20 Nitric Acid -> 1 Resin + 20 Nitric Macerate.
    - The furnace/transmutation branch is intentionally not invented in this pass; its final product still needs to be defined.
Version: 0.2.2
Date: 2026-09-19
  Features:
    - Added the Chitin Crusher, a planet-usable red-tinted clone of the Space Age Crusher.
    - Added a dedicated gz-chitin-crushing recipe category.
    - Added a west-side water input and east-side Biter Dregs output; both rotate with the machine.
  Changes:
    - Chitin Extraction now runs in the Chitin Crusher instead of a generic chemistry machine.
    - The Chitin Crusher currently uses the vanilla Crusher crafting ingredients and is enabled directly.
Version: 0.2.1
Date: 2026-09-18
  Changes:
    - Made GZ-Chemistry and GZ-Pipeworks hard dependencies.
    - Chitin macerates now always use the Pipeworks corrosive-fluid routing contract.
Version: 0.2.0
Date: 2026-09-18

    - Locked the first full Chitin chemistry recipe baseline.
    - Chitin Extraction: 5 Shell Fragments + 20 Water -> 1 Chitin Extract + 10 Biter Dregs in 2 seconds.
    - Chitosan Resin: 2 Chitin Extract + 20 Nitric Acid -> 1 Chitosan Resin + 20 Nitric Macerate in 4 seconds.
    - Chitin Membrane: 2 Chitin Extract + 20 Water -> 1 Chitin Membrane in 3 seconds.
    - Sulfuric Maceration: 20 Biter Dregs + 20 Sulfuric Acid -> 20 Sulfuric Macerate in 4 seconds.
    - Oxidizing Macerate: 20 Sulfuric Macerate + 20 Nitric Macerate -> 40 Oxidizing Macerate in 3 seconds.
  Dependencies:
    - Requires GZ-Chemistry 0.1.1 for Nitric Acid and its upstream Saltpeter chemistry.
  Notes:
