# Heroes of Three Kingdoms
Godot 4 tactical RPG prototype inspired by classic turn-based Romance of the Three Kingdoms games. The current editor baseline is Godot 4.6.
## Current Slice
- Thirty-three campaign scenarios.
- Grid movement.
- Unit selection.
- Move, attack, wait, end turn.
- Enemy AI with movement, attacks, multiple MP tactic choices, and scenario target priorities.
- Hover tile and unit info.
- Damage forecast for selected-unit attacks.
- Terrain defense and avoid affect physical attack damage and hit chance.
- Min/max attack ranges and counterattack forecasts.
- MP tactics with low/high damage options, healing options, a skill list menu, damage/healing previews, and target overlays.
- Campaign inventory consumables with an item menu, HP/MP recovery preview, and target overlay.
- Weapon, armor, and accessory rewards can be stored, displayed, and equipped from the battle HUD.
- Scenario-specific pre-battle shop purchases spend campaign gold, save immediately, and sync into the upcoming battle inventory.
- Pre-battle Armory equipment changes save immediately and sync roster equipment plus inventory stock.
- Pre-battle Roster can move optional officers between sortie and reserve within scenario limits.
- Pre-battle Formation lets deployed officers swap starting positions inside scenario-defined cells.
- Escort scenarios can include required, non-controllable protected units.
- Campaign saves joined officers, future deployments can require prior recruitment, and choices can make officers leave.
- Completed saves reconcile officer join/leave rewards on load without replaying gold or items.
- Post-battle choices save a scenario-to-choice id ledger for safer future branch migrations.

## Run
1. Install Godot 4.
2. Open this folder as a Godot project.
3. Run the project. The main scene is `res://scenes/battle_scene.tscn`.
Campaign order lives at `res://data/campaign/campaign.json`. Scenarios live under `res://data/scenarios/`, with reusable officers, classes, items, skills, and terrain definitions under `res://data/defs/`.
Data files can be checked with `powershell -NoProfile -ExecutionPolicy Bypass -File tools\validate_data.ps1`.
Godot 4.6 migration readiness can be checked with `powershell -NoProfile -ExecutionPolicy Bypass -File tools\check_godot46_readiness.ps1`. The migration checklist lives in `docs/GODOT_4_6_MIGRATION.md`.
## Direction
The project should grow from a small playable battle into a campaign tactics RPG:
- Battle system first.
- Scenario and event scripting second.
- Progression, equipment, and class depth third.
- Portraits, cutscenes, and campaign presentation after the core loop is fun.
The code keeps portraits and other visual assets replaceable so generated original assets can be added later without changing battle rules.
