From d6eaa79838e6b5aa5913fcbf8d09e901ddd60966 Mon Sep 17 00:00:00 2001 From: Natalie Date: Thu, 25 Jun 2026 14:47:23 -0400 Subject: [PATCH] =?UTF-8?q?feat(@projects/@magic-civilization):=20?= =?UTF-8?q?=F0=9F=A6=8C=20p3-19=20(fauna)=20=E2=80=94=20over-hunting=20dep?= =?UTF-8?q?letes=20live=20populations=20=E2=86=92=20local=20extinction?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the player→ecology coupling for fauna (the USP: the living world reacts to the player). GdFaunaEcology.deplete_species #[func] resolves the string species id → numeric via the species library and calls EcologyEngine::deplete_population. combat_utils._roll_wild_creature_loot now passes the slain creature's tile into item_system.roll_fauna_drops, which calls EcologyState.fauna_ecology.deplete_species on every fauna kill — so sustained hunting drives a species to local extinction (is_extinct), and the engine's growth/emergence recover it once pressure eases. Logic stays in mc_ecology (Rail 1); GDScript only triggers + passes the tile. Verified: mc-ecology cargo green; dylib rebuilt + deployed; canonical GUT 745/0 (new roll_fauna_drops signature + caller load cleanly, deplete_species callable). p3-19 stays partial — flora-harvest half (chop/intensive → flora population) next.
