## 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.
