// 30 second timeout\n\n// Select optimal world (low ping, available)\nint worldId = connectionManager.selectOptimalWorld();\n\n// Check connection status\nboolean isConnected = connectionManager.isConnected();\nlong pingMs = connectionManager.getCurrentPing();\n```\n\n### LoginStateTracker\n\nMonitors login progress and provides callbacks.\n\n```java\nLoginStateTracker tracker = new LoginStateTracker();\n\n// Set state change callback\ntracker.setStateChangeCallback((oldState, newState) -> {\n System.out.println(\"Login state changed: \" + oldState + \" -> \" + newState);\n});\n\n// Get current state\nLoginState currentState = tracker.getCurrentState();\n\n// Get detailed status\nString detailedStatus = tracker.getDetailedStatus();\n\n// Get login session summary\nString summary = tracker.getSessionSummary();\n```\n\n## Login States\n\nThe system tracks the following states:\n\n- `DISCONNECTED` - Not connected to game servers\n- `CONNECTING` - Establishing network connection\n- `CONNECTED` - Connected but not authenticated\n- `AUTHENTICATING` - Sending login credentials\n- `LOGGED_IN` - Successfully authenticated and in game\n- `FAILED` - Login process failed\n- `RECONNECTING` - Attempting to reconnect after disconnection\n\n## Advanced Features\n\n### Auto-Reconnect\n\n```java\n// Enable automatic reconnection\nclient.setAutoReconnect(true);\n\n// The client will automatically attempt to reconnect if disconnected\n// Uses exponential backoff to avoid overwhelming servers\n```\n\n### State Monitoring\n\n```java\n// Monitor login state changes\nclient.setupLoginMonitoring((oldState, newState) -> {\n System.out.println(\"State transition: \" + oldState + \" -> \" + newState);\n \n if (newState == LoginState.LOGGED_IN) {\n // Start your agent's main logic\n startAgentBehavior();\n } else if (newState == LoginState.FAILED) {\n // Handle login failure\n handleLoginFailure();\n }\n});\n```\n\n### Credential File Encryption\n\nCredentials are stored using AES encryption:\n\n```java\n// Create and save encrypted credentials\nLoginCredentials creds = new LoginCredentials();\ncreds.setCredentials(\"username\", \"password\");\ncreds.saveToFile(\"agent-creds.dat\", \"secure-master-password\");\n\n// Later, load encrypted credentials\nLoginCredentials loadedCreds = new LoginCredentials();\nloadedCreds.loadFromFile(\"agent-creds.dat\", \"secure-master-password\");\n```\n\n**Security Note**: Use a strong master password and store it securely. The master password is used to encrypt/decrypt the credentials file.\n\n## Error Handling\n\nThe system provides comprehensive error information:\n\n```java\nif (!loginResult) {\n String error = loginManager.getLastError();\n \n // Common error types:\n // - \"Invalid credentials\"\n // - \"Connection timeout\"\n // - \"Server unavailable\"\n // - \"Account locked\"\n // - \"World is full\"\n \n System.out.println(\"Login failed: \" + error);\n}\n```\n\n## Testing\n\nRun the comprehensive test suite:\n\n```bash\n./gradlew test --tests \"*LoginSystemTest*\"\n```\n\nThe test suite covers:\n- Credential validation and encryption\n- State tracking and transitions\n- Connection management\n- Integration with ModernizedClient\n- Error handling scenarios\n\n## Best Practices for AI Agents\n\n### 1. Reliable Connection\n\n```java\n// Always enable auto-reconnect for agents\nclient.setAutoReconnect(true);\n\n// Use appropriate timeouts\nclient.login(60); // 60 seconds for slower connections\n```\n\n### 2. State Monitoring\n\n```java\n// Monitor connection state continuously\nclient.setupLoginMonitoring((oldState, newState) -> {\n if (newState == LoginState.DISCONNECTED) {\n // Pause agent activities until reconnected\n pauseAgentActivities();\n } else if (newState == LoginState.LOGGED_IN) {\n // Resume agent activities\n resumeAgentActivities();\n }\n});\n```\n\n### 3. Credential Security\n\n```java\n// Store credentials in encrypted files, not in source code\nString credentialsFile = \"agent-\" + agentId + \"-creds.dat\";\nif (client.loadLoginCredentials(credentialsFile)) {\n client.login();\n} else {\n System.err.println(\"Failed to load credentials\");\n}\n```\n\n### 4. Error Recovery\n\n```java\n// Implement retry logic for transient failures\nif (!loginResult) {\n String error = loginManager.getLastError();\n if (error.contains(\"timeout\") || error.contains(\"server unavailable\")) {\n // Wait and retry for transient errors\n Thread.sleep(5000);\n client.login();\n } else {\n // Handle permanent errors (invalid credentials, etc.)\n handlePermanentError(error);\n }\n}\n```\n\n## Integration with Agent Workflows\n\nThe login system is designed to integrate seamlessly with agent decision-making:\n\n```java\npublic class MyAgent {\n private ModernizedClient client;\n private boolean gameplayActive = false;\n \n public void start() {\n client = new ModernizedClient();\n client.start();\n \n // Setup login monitoring\n client.setupLoginMonitoring((oldState, newState) -> {\n switch (newState) {\n case LOGGED_IN:\n gameplayActive = true;\n startMainGameplayLoop();\n break;\n case DISCONNECTED:\n case FAILED:\n gameplayActive = false;\n pauseAllActivities();\n break;\n }\n });\n \n // Load credentials and login\n if (client.loadLoginCredentials(\"my-agent-creds.dat\")) {\n client.setAutoReconnect(true);\n client.login();\n }\n }\n \n private void startMainGameplayLoop() {\n // Your agent's main gameplay logic\n while (gameplayActive && client.isLoggedIn()) {\n // Perform agent actions\n performAgentActions();\n \n // Brief pause between actions\n Thread.sleep(1000);\n }\n }\n}\n```\n\n## Troubleshooting\n\n### Common Issues\n\n1. **Login Timeout**\n - Increase timeout value\n - Check network connectivity\n - Try different world servers\n\n2. **Invalid Credentials**\n - Verify username/password\n - Check if account is locked\n - Ensure credentials file is not corrupted\n\n3. **Connection Failed**\n - Check firewall settings\n - Verify game servers are online\n - Try connecting manually first\n\n### Debug Information\n\n```java\n// Enable detailed logging\nSystem.setProperty(\"openosrs.login.debug\", \"true\");\n\n// Get detailed status\nString status = client.getLoginStatus();\nSystem.out.println(\"Login Status: \" + status);\n\n// Get connection information\nGameConnectionManager conn = client.getLoginManager().getConnectionManager();\nSystem.out.println(\"Connected: \" + conn.isConnected());\nSystem.out.println(\"Ping: \" + conn.getCurrentPing() + \"ms\");\n```\n\n## Future Enhancements\n\nPlanned improvements:\n- Multi-account support for managing multiple agents\n- World-hopping for optimal gameplay conditions\n- Login queue management for busy servers\n- Advanced reconnection strategies\n- Integration with proxy servers for distributed agents\n\n---\n\n**Note**: This login system is designed specifically for AI agents to automate RuneScape gameplay. Always comply with game rules and terms of service when using automated clients.\n \ No newline at end of file diff --git a/modernized-client/PROJECT_COMPLETION.md b/modernized-client/PROJECT_COMPLETION.md deleted file mode 100644 index 1503082..0000000 --- a/modernized-client/PROJECT_COMPLETION.md +++ /dev/null @@ -1 +0,0 @@ -# Project Status: Automated Login System Complete\n\n## ✅ COMPLETED FEATURES\n\n### Core Login System Components\n\n1. **LoginManager** (`/src/main/java/com/openosrs/client/login/LoginManager.java`)\n -
