package provides a complete housing system for EverQuest II servers, allowing players to purchase, manage, and customize their in-game homes. + +## Overview + +This package implements a streamlined housing system with three core components: +- **House**: Represents purchasable house types/zones with costs and requirements +- **CharacterHouse**: Represents houses owned by specific characters +- **HousingManager**: Orchestrates all housing operations including purchases, upkeep, and packet communication + +## Features + +### House Management +- Multiple house types with different costs, requirements, and features +- Alignment and guild level restrictions +- Vault storage slots and exit coordinates +- Configurable costs in coins and status points + +### Character Houses +- Individual house ownership tracking +- Upkeep payment system with automatic processing +- House settings (name, visit permissions, notes) +- Access control lists for other players +- Item placement and management +- Transaction history tracking + +### System Features +- Automatic upkeep processing with configurable grace periods +- Foreclosure system for unpaid upkeep +- Maximum house limits per player +- Integrated packet building for client communication +- Database persistence with MySQL support +- Comprehensive logging and error handling + +## Usage + +### Basic Setup + +```go +import

Packet sent to client +} + +// Send player's house list to client +err := hm.SendCharacterHousesPacket(characterID, clientVersion) +// Housing list packet sent to client +``` + +## Architecture + +### Core Types + +- **House**: Static house type definitions loaded from database +- **CharacterHouse**: Player-owned house instances with settings and history +- **HousingManager**: Central coordinator for all housing operations + +### Database Integration + +The housing system integrates with MySQL databases using the centralized database package: + +```sql +-- House type definitions +character_house_zones (id, name, cost_coins, cost_status, ...) + +-- Player house instances +character_houses (unique_id, char_id, house_id, upkeep_due, ...) +``` + +### Packet Integration + +Integrates with the centralized packet system using XML-driven packet definitions: +- Uses `packets.GetPacket()` to load packet definitions +- Builds packets with `packets.NewPacketBuilder()` +- Supports multiple client versions automatically + +## Configuration + +### HousingConfig Options + +- `EnableUpkeep`: Enable automatic upkeep processing +- `EnableForeclosure`: Allow foreclosure of houses with overdue upkeep +- `UpkeepGracePeriod`: Grace period in seconds before foreclosure +- `MaxHousesPerPlayer`: Maximum houses per character +- `EnableStatistics`: Enable housing statistics tracking + +### House Types + +House types are configured in the database with these properties: +- **Cost**: Coin and status point requirements +- **Upkeep**: Weekly maintenance costs +- **Alignment**: Good/Evil/Neutral/Any restrictions +- **Guild Level**: Minimum guild level required +- **Vault Slots**: Number of storage slots provided +- **Zone Info**: Location and exit coordinates + +## Constants + +The package provides extensive constants for: +- **House Types**: Cottage, Mansion, Keep, etc. +- **Access Levels**: Owner, Friend, Visitor, Guild Member +- **Transaction Types**: Purchase, Upkeep, Deposit, etc. +- **Permission Flags**: Enter, Place Items, Vault Access, etc. +- **Status Codes**: Active, Upkeep Due, Foreclosed, etc. + +See `constants.go` for complete listings and default values. + +## Interfaces + +### Logger Interface + +Implement this interface to provide logging: + +```go +type Logger interface { + LogInfo(system, format string, args ...interface{}) + LogError(system, format string, args ...interface{}) + LogDebug(system, format string, args ...interface{}) + LogWarning(system, format string, args ...interface{}) +} +``` + +### PlayerManager Interface + +Implement this interface to integrate with player systems: + +```go +type PlayerManager interface { + CanPlayerAffordHouse(characterID int32, coinCost, statusCost int64) (bool, error) + DeductPlayerCoins(characterID int32, amount int64) error + DeductPlayerStatus(characterID int32, amount int64) error + GetPlayerAlignment(characterID int32) (int8, error) + GetPlayerGuildLevel(characterID int32) (int8, error) +} +``` + +## Utility Functions + +### Currency Formatting + +```go +housing.FormatCurrency(15250) // Returns "1g 52s 50c" +housing.FormatCurrency(1000) // Returns "10s" +housing.FormatCurrency(50) // Returns "50c" +``` + +### Upkeep Date Formatting + +```go +housing.FormatUpkeepDue(time.Now().Add(24 * time.Hour)) // "Due in 1 days" +housing.FormatUpkeepDue(time.Now().Add(-24 * time.Hour)) // "Overdue (1 days)" +``` + +## Testing + +The package includes comprehensive tests with mock implementations: + +```bash +go test ./internal/housing/ -v +``` + +Tests cover: +- House and CharacterHouse creation +- Purchase validation (funds, alignment, guild level) +- Upkeep processing and foreclosure +- Packet building integration +- Currency and date formatting +- Full system integration scenarios + +## Error Handling + +The housing system provides detailed error codes and messages: + +- `HouseErrorInsufficientFunds`: Player cannot afford purchase/upkeep +- `HouseErrorAlignmentRestriction`: Player alignment doesn't meet requirements +- `HouseErrorGuildLevelRestriction`: Player guild level too low +- `HouseErrorMaxHousesReached`: Player at house limit +- `HouseErrorHouseNotFound`: Invalid house type requested + +See `constants.go` for complete error code definitions. + +## Performance + +The housing system is designed for efficiency: +- **In-Memory Caching**: House types and character houses cached in memory +- **Lazy Loading**: Character houses loaded on first access +- **Background Processing**: Upkeep processing runs asynchronously +- **Optimized Queries**: Direct SQL queries without ORM overhead +- **Minimal Allocations**: Reuses data structures where possible + +## Thread Safety + +All housing operations are thread-safe: +- `sync.RWMutex` protects shared data structures +- Database operations use connection pooling +- Concurrent access to houses is properly synchronized + +## Future Enhancements + +Potential areas for extension: +- House decoration and furniture systems +- Guild halls with special permissions +- Real estate marketplace for player trading +- Rental system for temporary housing +- Advanced statistics and reporting +- Integration with crafting systems \ No newline at end of file diff --git a/internal/housing/database.go
