Coheronia - Godot Survival Settlement Sandbox
Go to the Wiki
TL;DR: A Godot 4 side-view survival sandbox where digging, building, and feeding a settlement feed three real systemic pressures — Coherence / Load / Resilience — on the road to ruling a small civilization.
What it is
Coheronia is a side-view survival settlement sandbox built in Godot 4 (GDScript), inspired by Terraria-style mining and building, survival crafting, and civilization sims. You reshape terrain directly while managing a settlement whose health is computed from real world state — shelter, light, food, threats — not decorative meters. As of v0.6, the game launches into a persistent shell for characters, worlds, saves, and simulation settings, with each world stored as a configured simulation container in its own JSON save file.
Why it exists
The long-term fantasy is bigger than solo survival: carve out a place in a hostile world, rule a small civilization, and watch its needs, fears, politics, and defenses push back through play. The current shell already stores future-facing knobs (morale, loyalty decay, rebellion, ruler pressure) as world rules so later systems can consume them without rewriting the save model.
Core features
- Persistent shell: character creation (five playable ancestries with live effects), world creation with presets, six difficulty axes, and rule toggles
- Character-owned inventory, hotbar, and tools that travel between worlds, with drag-and-drop backpack/dock organization, compatible equipment swaps, and unequipping
- Data-driven enemies (surface slime, cave crawler, raider) with drops and difficulty-scaled density
- Player XP across six types plus base progression: Camp → Hamlet → Village gating population growth
- Config-driven deterministic world generation with per-block seed channels
- Automated smoke harness exercising the real gameplay path with 334 assertions; the last recorded full run is 332/334, with the remaining regressions documented in the wiki
Architecture
A shell scene manages profiles, characters, and worlds; the playable scene owns day/night, storms, threats, and population flow. JSON data authorities (blocks, recipes, enemies, ancestries, settlement_rules, progression tables) drive behavior, loaded through registry autoloads. Known limits are documented honestly: provisional art, abstract population, finite single-biome terrain, and two tracked full-smoke regressions.
