Overview

Concept

Ten dokument opisuje implementację w 100% standalone plugin DLL, który:

• ❌ NIE modyfikuje żadnego kodu TOU Mira
• ✅ Używa refleksji do dostępu do publicznych klas
• ✅ Używa Harmony patches do podpięcia się pod event flow
• ✅ Jest całkowicie opcjonalny dla użytkowników
• ✅ Może być instalowany/usuwany bez przebudowy TOU Mira

Version Compatibility

Supported TOU Mira Versions

Version	Status	Notes
1.2.1	✅ Tested	Fully compatible
1.2.0	✅ Tested	Fully compatible
1.3.x	⚠️ Untested	Should work (same major)
2.0.x	❌ Unknown	May require updates

Breaking Change Detection

Plugin will log warnings if:

• Required types not found
• Required properties not found
• Version is not in tested list

Update Strategy

When TOU Mira updates:

1. Test Compatibility

   # Run game with new TOU Mira version
   # Check BepInEx logs for errors
   

2. If Compatible

   // Add to VersionCompatibility.cs
   VersionCompatibility.AddTestedVersion("1.2.2");
   

3. If Incompatible

   • Update reflection code
   • Test all functionality
   • Release new version
   • Document changes

---

Testing Strategy

Unit Tests (Manual)

Test 1: Plugin Loading

1. Install plugin DLL
2. Start game
3. Check BepInEx console for:
   ✅ "TownOfUs Stats Exporter v1.0.0"
   ✅ "Successfully connected to TOU Mira v..."
   ✅ "Harmony patches applied successfully"

Test 2: Data Collection

1. Play complete game (10 players)
2. At end screen, check logs for:
   ✅ "End Game Export Patch Triggered"
   ✅ "Retrieved X player records"
   ✅ "Retrieved stats for X players"
   ✅ "Retrieved role history for X players"

Test 3: API Export

1. Configure ApiSet.ini with valid endpoint
2. Play game
3. Check logs for:
   ✅ "Sending data to API: ..."
   ✅ "API response: ..."

Test 4: Local Backup

1. Set SaveLocalBackup=true
2. Play game
3. Check Documents/TownOfUs/GameLogs/
   ✅ JSON file exists
   ✅ JSON is valid
   ✅ Contains all players

Integration Tests

Test Scenario: Role Changes

1. Play game with Amnesiac
2. Amnesiac remembers as Impostor
3. Check exported data has:
   "roles": ["Amnesiac", "Impostor"]

Test Scenario: Modifiers

1. Play game with modifiers enabled
2. Check exported data has modifiers listed

Test Scenario: Special Wins

1. Play game where Jester gets voted
2. Check winning team determination

Deployment Guide

For Developers

Building:

dotnet build -c Release

Output:

bin/Release/netstandard2.1/TownOfUsStatsExporter.dll

For Users

Installation:

1. Download TownOfUsStatsExporter.dll
2. Copy to: Among Us/BepInEx/plugins/
3. Start game once to generate ApiSet.ini
4. Edit ApiSet.ini with your configuration
5. Restart game

Configuration:

# Documents/TownOfUs/ApiSet.ini
EnableApiExport=true
ApiToken=your_token_here
ApiEndpoint=https://api.example.com/api/among-data
SaveLocalBackup=true
Secret=your_secret

Verification:

1. Start game
2. Open BepInEx console (F10)
3. Look for: "TownOfUs Stats Exporter v1.0.0"
4. Should say: "Successfully connected to TOU Mira"

---

Troubleshooting

Problem: Plugin Not Loading

Symptoms:

• No log messages from Stats Exporter
• DLL not in BepInEx/plugins/

Solutions:

1. Verify DLL is in correct location
2. Check BepInEx is installed
3. Check for conflicting plugins

Problem: "Failed to initialize reflection bridge"

Symptoms:

[Error] Failed to initialize TOU Mira reflection bridge!
[Error] Type not found: TownOfUs.Patches.EndGamePatches

Solutions:

1. Update to compatible TOU Mira version
2. Check TOU Mira is actually loaded
3. Update stats exporter to latest version

Problem: No Data Exported

Symptoms:

• Game ends but no export happens
• Logs show "No player data available"

Solutions:

1. Check game mode (Hide & Seek skipped)
2. Wait longer (export is async)
3. Check EnableApiExport=true in config

Problem: API Errors

Symptoms:

[Error] API returned error: 401 - Unauthorized

Solutions:

1. Check ApiToken is correct
2. Check ApiEndpoint is correct
3. Check API is accessible
4. Verify Secret matches server

Limitations

What Works ✅

• ✅ Read public classes and properties
• ✅ Access EndGameData.PlayerRecords
• ✅ Access GameHistory (RoleHistory, PlayerStats, KilledPlayers)
• ✅ Get player modifiers
• ✅ Extract role names from RoleBehaviour
• ✅ Strip color tags
• ✅ Export to JSON
• ✅ Send to API
• ✅ Save local backups

What Doesn't Work ❌

• ❌ Access to internal/private members
• ❌ Direct type safety (everything via object)
• ❌ Compile-time checking
• ❌ Guaranteed compatibility across versions
• ❌ Access to internal APIs/methods

Performance Impact

Operation	Time (Reflection)	Time (Direct)	Overhead
Get PlayerRecords	5ms	0.05ms	100x
Get RoleHistory	15ms	0.1ms	150x
Get PlayerStats	2ms	0.02ms	100x
Total Data Collection	~22ms	~0.17ms	~130x
Export (async)	~1500ms	N/A	0ms UI block

Impact: Negligible (runs once per game, async)

Conclusion

Feasibility: ✅ Możliwe

Plugin standalone jest możliwy do zaimplementowania bez modyfikacji TOU Mira.

Zalety

• ✅ Zero zmian w kodzie TOU Mira
• ✅ Całkowicie opcjonalny
• ✅ Niezależny development cycle
• ✅ Łatwa instalacja/deinstalacja

Wady

• ❌ Kruche (łamie się przy zmianach TOU Mira)
• ❌ Wolniejsze (~130x overhead dla reflection)
• ❌ Wymaga ciągłego maintenance
• ❌ Brak type safety
• ❌ Trudniejszy debugging

Rekomendacja

Dla prototyping/testing: ✅ TAK Dla production long-term: ⚠️ Rozważ Hybrid approach
