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

• Nineteen 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.
• Reloading during a pending post-battle choice returns to the choice panel instead of skipping the branch.
• Qingzhou victory can recruit Dian Wei, backed by a new Warrior class.
• Puyang uses Dian Wei as a required joined officer and introduces a Lu Bu branch choice.
• Dingtao consumes the Puyang branch flags and rewards a stronger axe.
• Wan Castle consumes the imperial escort branch flags and adds a protected Cao Ang escape map.
• Xiapi consumes the Wan Castle branch flags and adds a flood-gate siege against Lu Bu.
• Xiapi victory recruits Guo Jia, and White Horse starts the northern campaign with a decoy-line battle.
• Yan Ford consumes the White Horse branch flags and adds Wen Chou's countercharge before Guandu.
• Guandu consumes the Yan Ford branch flags and adds Yuan Shao's main assault.
• Wuchao consumes the Guandu branch flags and adds a depot-burning raid.
• Cangting consumes the Wuchao branch flags, breaks Yuan Shao's rear guard, and recruits Zhang He.
• Ye consumes the Cangting branch flags and lets Zhang He deploy against the Yuan heirs.
• Ye Siege consumes the Ye campaign branch flags and stages an inner-gate breach.
• Ye Surrender consumes the siege branch flags and settles the city before the Yuan heirs flee north.
• Northern Pursuit consumes the Ye surrender branch flags and pushes Yuan Shang's rearguard north from Ye.
• Nanpi Pressure consumes the Northern Pursuit branch flags and breaks Yuan Tan's outer line.
• Post-battle choices can save campaign flags that branch later briefing text, shop stock, and scenario events.
• Scenario post-battle dialogue can play before the victory result panel.

• Victory results summarize saved player level-ups and promotions.
• Scenario events for battle start, battle-begin dialogue, turn start, movement-triggered ambushes, objective updates, and reinforcements.
• Scenario briefing before battle.
• Victory rewards and consumed inventory saved into a campaign state.
• Scenario-defined victory and defeat conditions.
• Destination-style victory conditions with objective map markers.
• Protected-unit defeat conditions for escort battles.
• Turn-limit defeat conditions with turn-limit HUD display.
• Next-battle flow after victory.
• Campaign completion screen.
• New campaign save reset.
• Victory and defeat result overlay.
• Data-driven scenario setup through JSON definitions and deployments.

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.
