# EQ2Go Conversion Session Summary
## Project Overview
EQ2Go is a Go rewrite of the EverQuest II server emulator from C++ EQ2EMu. This session focused on converting C++ systems to modern Go packages following existing architectural patterns.
## Completed Conversions
### 1. Player System (internal/player)
**Source:** `internal/Player.h` (1277 lines), `internal/Player.cpp` (1000 lines)
**Created:** 15 files including comprehensive player management system
- Thread-safe player state management with embedded entity.Entity
- Character flags (CF_COMBAT_EXPERIENCE_ENABLED through CF2_80000000)
- Complete player lifecycle management with database persistence
- Event handling and statistics tracking
- Integration interfaces for seamless system interaction
### 2. Groups System (internal/groups)
**Source:** `internal/PlayerGroups.h`, `internal/PlayerGroups.cpp`
**Decision:** Separate package due to independent functionality and global state
**Created:** 7 files supporting individual groups (6 members) and raids (24 players)
- Cross-server group coordination
- Thread-safe group management with leader elections
- Raid functionality supporting 4 groups
- Complete group lifecycle with invite/kick/leave mechanics
### 3. Alt Advancement System (internal/alt_advancement)
**Source:** `internal/AltAdvancement.h`, `internal/AltAdvancement.cpp`, `internal/AltAdvancementDB.cpp`
**Created:** 7 files with complete AA progression system
- **10 AA Tabs:** Class, Subclass, Shadow, Heroic, Tradeskill, Prestige, Tradeskill Prestige, Dragon, Dragon Class, Far Seas
- **Master Lists:** MasterAAList with fast lookups by spell/node ID, MasterAANodeList for tree configurations
- **Player Progression:** AAPlayerState with templates, point management, and purchase tracking
- **Database Operations:** Complete persistence with SQL operations for AA definitions, player progress, and templates
- **Thread Safety:** Comprehensive mutex usage with atomic operations
- **Event System:** Purchase/refund events, template changes, point awards
- **Validation:** Prerequisites, level requirements, class restrictions

)
// Get maximum AA points for each tab
maxClassAA := alt_advancement.GetMaxAAForTab(alt_advancement.AA_CLASS) // 100
maxHeroicAA := alt_advancement.GetMaxAAForTab(alt_advancement.AA_HEROIC) // 50
```
## Database Integration
```go
// Custom database implementation
type MyAADatabase struct {
db *sql.DB
}
func (db *MyAADatabase) LoadAltAdvancements() error {
// Load AA definitions from database
return nil
}
func (db *MyAADatabase) LoadPlayerAA(characterID int32) (*AAPlayerState, error) {
// Load player AA data from database
return nil, nil
}
func (db *MyAADatabase) SavePlayerAA(playerState *AAPlayerState) error {
// Save player AA data to database
return nil
}
// Set database implementation
aaManager.SetDatabase(&MyAADatabase{db: myDB})
```
## Event Handling
```go
// Custom event handler
type MyAAEventHandler struct{}
func (h *MyAAEventHandler) OnAAPurchased(characterID int32, nodeID int32, newRank int8, pointsSpent int32) error {
fmt.Printf("Player %d purchased AA %d rank %d for %d points\n",
characterID, nodeID, newRank, pointsSpent)
return nil
}
func (h *MyAAEventHandler) OnAATemplateChanged(characterID int32, oldTemplate, newTemplate int8) error {
fmt.Printf("Player %d changed template from %d to %d\n",
characterID, oldTemplate, newTemplate)
return nil
}
func (h *MyAAEventHandler) OnPlayerAAPointsChanged(characterID int32, oldPoints, newPoints int32) error {
fmt.Printf("Player %d AA points changed from %d to %d\n",
characterID, oldPoints, newPoints)
return nil
}
// Register event handler
aaManager.SetEventHandler(&MyAAEventHandler{})
```
## Validation System
```go
// Custom validator
type MyAAValidator struct{}
func (v *MyAAValidator) ValidateAAPurchase(playerState *AAPlayerState, nodeID int32, targetRank int8) error {
// Check if player has enough points
if playerState.AvailablePoints < int32(targetRank) {
return fmt.Errorf("insufficient AA points")
}
// Check prerequisites
// ... validation logic
return nil
}
func (v *MyAAValidator) ValidatePlayerLevel(playerState *AAPlayerState, aaData *AltAdvanceData) error {
// Check minimum level requirement
// ... validation logic
return nil
}
// Set validator
aaManager.SetValidator(&MyAAValidator{})
```
## Statistics and Monitoring
```go
// Get system statistics
stats := aaManager.GetSystemStats()
fmt.Printf("Total AAs loaded: %d\n", stats.TotalAAsLoaded)
fmt.Printf("Active players: %d\n", stats.ActivePlayers)
fmt.Printf("Total purchases: %d\n", stats.TotalAAPurchases)
fmt.Printf("Average points spent: %.1f\n", stats.AveragePointsSpent)
// Get player-specific statistics
playerStats := aaManager.GetPlayerStats(characterID)
fmt.Printf("Player stats: %+v\n", playerStats)
// Get database statistics (if database supports it)
if db, ok := aaManager.database.(*DatabaseImpl); ok {
dbStats, err := db.GetAAStatistics()
if err == nil {
fmt.Printf("Database stats: %+v\n", dbStats)
}
}
```
## Configuration Options
```go
// Configure the AA system
config := alt_advancement.AAManagerConfig{
EnableAASystem: true,
EnableCaching: true,
EnableValidation: true,
EnableLogging: false,
AAPointsPerLevel: 2,
MaxBankedPoints: 30,
EnableAABanking: true,
CacheSize: 10000,
UpdateInterval: 1 * time.Second,
BatchSize: 100,
DatabaseEnabled: true,
AutoSave: true,
SaveInterval: 5 * time.Minute,
}
aaManager.SetConfig(config)
```
## Caching System
```go
// Enable caching for better performance
cache := alt_advancement.NewSimpleAACache(1000)
aaManager.SetCache(cache)
// Get cache statistics
cacheStats := cache.GetStats()
fmt.Printf("Cache hits: %d, misses: %d\n",
cacheStats["hits"], cacheStats["misses"])
```
## Packet Handling Integration
```go
// Custom packet handler
type MyAAPacketHandler struct{}
func (ph *MyAAPacketHandler) GetAAListPacket(client interface{}) ([]byte, error) {
// Build AA list packet for client
return []byte{}, nil
}
func (ph *MyAAPacketHandler) SendAAUpdate(client interface{}, playerState *AAPlayerState) error {
// Send AA update to client
return nil
}
func (ph *MyAAPacketHandler) HandleAAPurchase(client interface{}, nodeID int32, rank int8) error {
// Handle AA purchase from client
return nil
}
// Set packet handler
aaManager.SetPacketHandler(&MyAAPacketHandler{})
```
## Advanced Usage
### Custom AA Trees
```go
// Create custom AA data
customAA := &alt_advancement.AltAdvanceData{
SpellID: 2001,
NodeID: 2001,
Name: "Custom Ability",
Description: "A custom AA ability",
Group: alt_advancement.AA_CLASS,
Col: 1,
Row: 1,
Icon: 100,
RankCost: 1,
MaxRank: 5,
MinLevel: 20,
ClassReq: 1, // Fighter only
}
// Add to master list
err := masterAAList.AddAltAdvancement(customAA)
if err != nil {
log.Printf("Failed to add custom AA: %v", err)
}
```
### Bulk Operations
```go
// Award AA points to multiple players
playerIDs := []int32{1001, 1002, 1003}
for _, playerID := range playerIDs {
err := aaManager.AwardAAPoints(playerID, 5, "Server event bonus")
if err != nil {
log.Printf("Failed to award points to player %d: %v", playerID, err)
}
}
// Batch save player states
for _, playerID := range playerIDs {
err := aaManager.SavePlayerAA(playerID)
if err != nil {
log.Printf("Failed to save player %d AA data: %v", playerID, err)
}
}
```
## Thread Safety
All AA operations are thread-safe using appropriate synchronization:
- **RWMutex** for read-heavy operations (AA lookups, player state access)
- **Atomic operations** for simple counters and flags
- **Proper lock ordering** to prevent deadlocks
- **Background goroutines** for periodic processing and auto-save
- **Channel-based communication** for event handling
## Performance Considerations
- **Efficient data structures** with hash maps for O(1) lookups
- **Caching system** to reduce database queries
- **Batch processing** for bulk operations
- **Background processing** to avoid blocking gameplay
- **Statistics collection** with minimal overhead
- **Memory-efficient storage** with proper cleanup
## Integration with Other Systems
The AA system integrates with:
- **Player System** - Player-specific AA progression and point management
- **Spell System** - AA abilities are linked to spells
- **Class System** - Class-specific AA trees and requirements
- **Level System** - Level-based AA point awards and prerequisites
- **Database System** - Persistent storage of AA data and player progress
- **Client System** - AA UI updates and purchase handling
- **Achievement System** - AA milestones and progression tracking
## Migration from C++
This Go implementation maintains compatibility with the original C++ EQ2EMu AA system while providing:
- **Modern concurrency** with goroutines and channels
- **Better error handling** with Go's error interface
- **Cleaner architecture** with interface-based design
- **Improved maintainability** with package organization
- **Enhanced testing** capabilities
- **Type safety** with Go's type system
- **Memory management** with Go's garbage collector
## TODO Items
The conversion includes areas for future implementation:
- **Complete packet handling** for all client communication
- **Advanced validation** for complex AA prerequisites
- **Lua scripting integration** for custom AA behaviors
- **Web administration interface** for AA management
- **Performance optimizations** for large-scale deployments
- **Advanced caching strategies** with TTL and eviction policies
- **Metrics and monitoring** integration with external systems
- **AA import/export** functionality for configuration management
## Usage Examples
See the code examples throughout this documentation for detailed usage patterns. The system is designed to be used alongside the existing EQ2Go server infrastructure with proper initialization and configuration.
The AA system provides a solid foundation for character progression mechanics while maintaining the flexibility to extend and customize behavior through the comprehensive interface system.

# Groups System
The groups system (`internal/groups`) provides comprehensive player group and raid management for the EQ2Go server emulator. This system is converted from the original C++ EQ2EMu PlayerGroups implementation with modern Go concurrency patterns and clean architecture principles.
## Overview
The groups system manages all aspects of player groups and raids including:
- **Group Management**: Creation, disbanding, member management
- **Raid Functionality**: Multi-group coordination with up to 4 groups (24 players)
- **Cross-Server Groups**: Peer-to-peer group coordination across server instances
- **Group Invitations**: Invitation system with timeouts and validation
- **Group Communication**: Chat, messaging, and broadcast systems
- **Group Options**: Loot distribution, auto-split, leadership settings
- **Quest Sharing**: Share quests with group members
- **Group Buffs**: Coordinated buff management across group members
- **Statistics**: Comprehensive group activity tracking
## Architecture
### Core Components
**Group** - Individual group with up to 6 members, options, and raid functionality
**GroupManager** - Global group management, invitations, and coordination
**Service** - High-level service interface with validation and configuration
**GroupMemberInfo** - Detailed member information and statistics
**GroupOptions** - Group behavior and loot configuration
### Key Files
- `group.go` - Core Group struct and member management
- `manager.go` - GroupManager with global group coordination
- `service.go` - High-level Service interface with validation
- `types.go` - Data structures and type definitions
- `interfaces.go` - System integration interfaces and adapters
- `constants.go` - All group system constants and limits
- `README.md` - This documentation
## Group Creation and Management
```go
// Create group service
config := groups.DefaultServiceConfig()
service := groups.NewService(config)
service.Start()
// Create a new group
leader := &entity.Player{...}
options := &groups.GroupOptions{
LootMethod: groups.LOOT_METHOD_ROUND_ROBIN,
AutoSplit: groups.AUTO_SPLIT_ENABLED,
}
groupID, err := service.CreateGroup(leader, options)
// Get group information
groupInfo, err := service.GetGroupInfo(groupID)
fmt.Printf("Group %d has %d members\n", groupInfo.GroupID, groupInfo.Size)
```
## Group Invitations
```go
// Invite a player to the group
leader := &entity.Player{...}
member := &entity.Player{...}
// Send invitation
err := service.InviteToGroup(leader, member)
if err != nil {
fmt.Printf("Invitation failed: %v\n", err)
}
// Accept invitation
err = service.AcceptGroupInvite(member)
if err != nil {
fmt.Printf("Failed to accept: %v\n", err)
}
// Decline invitation
service.DeclineGroupInvite(member)
```
## Group Member Management
```go
// Get group manager directly
manager := service.GetManager()
// Add member to existing group
err := manager.AddGroupMember(groupID, member, false)
// Remove member from group
err := manager.RemoveGroupMember(groupID, member)
// Transfer leadership
err := service.TransferLeadership(groupID, newLeader)
// Check if entity is in group
isInGroup := manager.IsInGroup(groupID, member)
// Get group leader
leader := manager.GetGroupLeader(groupID)
```
## Group Communication
```go
// Send simple message to group
manager.SimpleGroupMessage(groupID, "Welcome to the group!")
// Send system message
manager.SendGroupMessage(groupID, groups.GROUP_MESSAGE_TYPE_SYSTEM, "Group is ready!")
// Send chat message from member
manager.GroupChatMessage(groupID, fromEntity, 0, "Hello everyone!", groups.CHANNEL_GROUP_SAY)
// Send formatted chat message
manager.SendGroupChatMessage(groupID, groups.CHANNEL_GROUP_CHAT, "Raid starting in 5 minutes")
```
## Group Options Configuration
```go
// Configure group options
options := groups.GroupOptions{
LootMethod: groups.LOOT_METHOD_NEED_BEFORE_GREED,
LootItemsRarity: groups.LOOT_RARITY_RARE,
AutoSplit: groups.AUTO_SPLIT_ENABLED,
GroupLockMethod: groups.LOCK_METHOD_INVITE_ONLY,
GroupAutolock: groups.AUTO_LOCK_ENABLED,
AutoLootMethod: groups.AUTO_LOOT_ENABLED,
}
// Apply options to group
err := manager.SetGroupOptions(groupID, &options)
// Get current options
currentOptions, exists := manager.GetDefaultGroupOptions(groupID)
if exists {
fmt.Printf("Loot method: %d\n", currentOptions.LootMethod)
}
```
## Raid Management
```go
// Form a raid from multiple groups
leaderGroupID := int32(1)
targetGroups := []int32{2, 3, 4}
err := service.FormRaid(leaderGroupID, targetGroups)
if err != nil {
fmt.Printf("Failed to form raid: %v\n", err)
}
// Check if groups are in same raid
isInRaid := manager.IsInRaidGroup(groupID1, groupID2, false)
// Get all raid groups for a group
raidGroups := manager.GetRaidGroups(groupID)
fmt.Printf("Raid has %d groups\n", len(raidGroups))
// Disband raid
err := service.DisbandRaid(leaderGroupID)
```
## Cross-Server Group Management
```go
// Add member from peer server
memberInfo := &groups.GroupMemberInfo{
Name: "RemotePlayer",
Leader: false,
IsClient: true,
ClassID: 1,
HPCurrent: 1500,
HPMax: 1500,
PowerCurrent: 800,
PowerMax: 800,
LevelCurrent: 50,
LevelMax: 50,
RaceID: 0,
Zone: "commonlands",
ZoneID: 220,
InstanceID: 0,
ClientPeerAddress: "192.168.1.10",
ClientPeerPort: 9000,
IsRaidLooter: false,
}
err := manager.AddGroupMemberFromPeer(groupID, memberInfo)
// Remove peer member by name
err = manager.RemoveGroupMemberByName(groupID, "RemotePlayer", true, 12345)
```
## Group Statistics and Information
```go
// Get service statistics
stats := service.GetServiceStats()
fmt.Printf("Active groups: %d\n", stats.ManagerStats.ActiveGroups)
fmt.Printf("Total invites: %d\n", stats.ManagerStats.TotalInvites)
fmt.Printf("Average group size: %.1f\n", stats.ManagerStats.AverageGroupSize)
// Get all groups in a zone
zoneGroups := service.GetGroupsByZone(zoneID)
for _, group := range zoneGroups {
fmt.Printf("Group %d has %d members in zone\n", group.GroupID, group.Size)
}
// Get groups containing specific members
members := []entity.Entity{player1, player2}
memberGroups := service.GetMemberGroups(members)
```
## Event Handling
```go
// Create custom event handler
type MyGroupEventHandler struct{}
func (h *MyGroupEventHandler) OnGroupCreated(group *groups.Group, leader entity.Entity) error {
fmt.Printf("Group %d created by %s\n", group.GetID(), leader.GetName())
return nil
}
func (h *MyGroupEventHandler) OnGroupMemberJoined(group *groups.Group, member entity.Entity) error {
fmt.Printf("%s joined group %d\n", member.GetName(), group.GetID())
return nil
}
func (h *MyGroupEventHandler) OnGroupDisbanded(group *groups.Group) error {
fmt.Printf("Group %d disbanded\n", group.GetID())
return nil
}
// ... implement other required methods
// Register event handler
handler := &MyGroupEventHandler{}
service.AddEventHandler(handler)
```
## Database Integration
```go
// Implement database interface
type MyGroupDatabase struct {
// database connection
}
func (db *MyGroupDatabase) SaveGroup(group *groups.Group) error {
// Save group to database
return nil
}
func (db *MyGroupDatabase) LoadGroup(groupID int32) (*groups.Group, error) {
// Load group from database
return nil, nil
}
// ... implement other required methods
// Set database interface
database := &MyGroupDatabase{}
service.SetDatabase(database)
```
## Packet Handling Integration
```go
// Implement packet handler interface
type MyGroupPacketHandler struct {
// client connection management
}
func (ph *MyGroupPacketHandler) SendGroupUpdate(members []*groups.GroupMemberInfo, excludeClient interface{}) error {
// Send group update packets to clients
return nil
}
func (ph *MyGroupPacketHandler) SendGroupInvite(inviter, invitee entity.Entity) error {
// Send invitation packet to client
return nil
}
// ... implement other required methods
// Set packet handler
packetHandler := &MyGroupPacketHandler{}
service.SetPacketHandler(packetHandler)
```
## Validation and Security
```go
// Implement custom validator
type MyGroupValidator struct{}
func (v *MyGroupValidator) ValidateGroupCreation(leader entity.Entity, options *groups.GroupOptions) error {
// Custom validation logic
if leader.GetLevel() < 10 {
return fmt.Errorf("must be level 10+ to create groups")
}
return nil
}
func (v *MyGroupValidator) ValidateGroupInvite(leader, member entity.Entity) error {
// Custom invitation validation
if leader.GetZone() != member.GetZone() {
return fmt.Errorf("cross-zone invites not allowed")
}
return nil
}
// ... implement other required methods
// Set validator
validator := &MyGroupValidator{}
service.SetValidator(validator)
```
## Configuration
### Service Configuration
```go
config := groups.ServiceConfig{
ManagerConfig: groups.GroupManagerConfig{
MaxGroups: 1000,
MaxRaidGroups: 4,
InviteTimeout: 30 * time.Second,
UpdateInterval: 1 * time.Second,
BuffUpdateInterval: 5 * time.Second,
EnableCrossServer: true,
EnableRaids: true,
EnableQuestSharing: true,
EnableStatistics: true,
},
AutoCreateGroups: true,
AllowCrossZoneGroups: true,
AllowBotMembers: true,
AllowNPCMembers: false,
MaxInviteDistance: 100.0,
GroupLevelRange: 10,
EnableGroupPvP: false,
EnableGroupBuffs: true,
DatabaseEnabled: true,
EventsEnabled: true,
StatisticsEnabled: true,
ValidationEnabled: true,
}
service := groups.NewService(config)
```
### Group Options
Available group options for loot and behavior management:
- **Loot Methods**: Leader only, round robin, need before greed, lotto
- **Loot Rarity**: Common, uncommon, rare, legendary, fabled
- **Auto Split**: Enable/disable automatic coin splitting
- **Group Lock**: Open, invite only, closed
- **Auto Lock**: Automatic group locking settings
- **Auto Loot**: Automatic loot distribution
## Constants and Limits
### Group Limits
- **MAX_GROUP_SIZE**: 6 members per group
- **MAX_RAID_GROUPS**: 4 groups per raid
- **MAX_RAID_SIZE**: 24 total raid members
### Invitation System
- **Default invite timeout**: 30 seconds
- **Invitation error codes**: Success, already in group, group full, declined, etc.
### Communication Channels
- **CHANNEL_GROUP_SAY**: Group say channel (11)
- **CHANNEL_GROUP_CHAT**: Group chat channel (31)
- **CHANNEL_RAID_SAY**: Raid say channel (35)
## Thread Safety
All group operations are thread-safe using appropriate synchronization:
- **RWMutex** for read-heavy operations (member lists, group lookups)
- **Atomic operations** for simple counters and flags
- **Channel-based communication** for message and update processing
- **Proper lock ordering** to prevent deadlocks
- **Background goroutines** for periodic processing
## Integration with Other Systems
The groups system integrates with:
- **Entity System** - Groups work with any entity (players, NPCs, bots)
- **Player System** - Player-specific group functionality and client handling
- **Quest System** - Quest sharing within groups
- **Spell System** - Group buffs and spell coordination
- **Zone System** - Cross-zone group management
- **Chat System** - Group communication channels
- **Database System** - Group persistence and recovery
- **Network System** - Cross-server group coordination
## Performance Considerations
- **Efficient member tracking** with hash maps for O(1) lookups
- **Batched message processing** to reduce overhead
- **Background processing** for periodic updates and cleanup
- **Memory-efficient data structures** with proper cleanup
- **Statistics collection** with minimal performance impact
- **Channel buffering** to prevent blocking on message queues
## Migration from C++
This Go implementation maintains compatibility with the original C++ EQ2EMu groups system while providing:
- **Modern concurrency** with goroutines and channels
- **Better error handling** with Go's error interface
- **Cleaner architecture** with interface-based design
- **Improved maintainability** with package organization
- **Enhanced testing** capabilities
- **Type safety** with Go's type system
## TODO Items
The conversion includes TODO comments marking areas for future implementation:
- **Quest sharing integration** with the quest system
- **Complete spell/buff integration** for group buffs
- **Advanced packet handling** for all client communication
- **Complete database schema** implementation
- **Cross-server peer management** completion
- **Bot and NPC integration** improvements
- **Advanced raid mechanics** (raid loot, raid targeting)
- **Group PvP functionality** implementation
- **Performance optimizations** for large-scale deployments
## Usage Examples
See the code examples throughout this documentation for detailed usage patterns. The system is designed to be used alongside the existing EQ2Go server infrastructure with proper initialization and configuration.
The groups system provides a solid foundation for MMO group mechanics while maintaining the flexibility to extend and customize behavior through the comprehensive interface system.

# Player System
The player system (`internal/player`) provides comprehensive player character management for the EQ2Go server emulator. This system is converted from the original C++ EQ2EMu Player implementation with modern Go concurrency patterns and clean architecture principles.
## Overview
The player system manages all aspects of player characters including:
- **Character Data**: Basic character information, stats, appearance
- **Experience**: Adventure and tradeskill XP, vitality, debt recovery
- **Skills**: Skill progression, bonuses, and management
- **Spells**: Spell book, casting, maintained effects, passive spells
- **Combat**: Auto-attack, combat state, weapon handling
- **Quests**: Quest tracking, progress, completion, rewards
- **Social**: Friends, ignore lists, guild membership
- **Economy**: Currency management, trading, banking
- **Movement**: Position tracking, spawn visibility, zone transfers
- **Character Flags**: Various character state flags and preferences
- **History**: Character history tracking and events
- **Items**: Inventory, equipment, appearance items
- **Housing**: House ownership, vault access
## Architecture
### Core Components
**Player** - Main player character struct extending Entity
**PlayerInfo** - Detailed character information for serialization
**PlayerManager** - Multi-player management and coordination
**PlayerControlFlags** - Character flag state management
**CharacterInstances** - Instance lockout tracking
### Key Files
- `player.go` - Core Player struct and basic functionality
- `player_info.go` - PlayerInfo struct for character sheet data
- `character_flags.go` - Character flag management
- `currency.go` - Coin and currency handling
- `experience.go` - XP, leveling, and vitality systems
- `combat.go` - Combat mechanics and processing
- `quest_management.go` - Quest system integration
- `spell_management.go` - Spell book and casting management
- `skill_management.go` - Skill system integration
- `spawn_management.go` - Spawn visibility and tracking
- `manager.go` - Multi-player management system
- `interfaces.go` - System integration interfaces
- `constants.go` - All character flag and system constants
- `types.go` - Data structures and type definitions
## Player Creation
```go
// Create a new player
player := player.NewPlayer()
// Set basic information
player.SetCharacterID(12345)
player.SetName("TestPlayer")
player.SetLevel(10)
player.SetClass(1) // Fighter
player.SetRace(0) // Human
// Initialize player info
info := player.GetPlayerInfo()
info.SetBindZone(1)
info.SetHouseZone(0)
```
## Character Flags
The system supports all EverQuest II character flags:
```go
// Set character flags
player.SetCharacterFlag(player.CF_ANONYMOUS)
player.SetCharacterFlag(player.CF_LFG)
player.ResetCharacterFlag(player.CF_AFK)
// Check flags
if player.GetCharacterFlag(player.CF_ROLEPLAYING) {
// Handle roleplaying state
}
```
### Available Flags
- **CF_COMBAT_EXPERIENCE_ENABLED** - Adventure XP enabled
- **CF_QUEST_EXPERIENCE_ENABLED** - Tradeskill XP enabled
- **CF_ANONYMOUS** - Anonymous mode
- **CF_ROLEPLAYING** - Roleplaying flag
- **CF_AFK** - Away from keyboard
- **CF_LFG** - Looking for group
- **CF_LFW** - Looking for work
- **CF_HIDE_HOOD/CF_HIDE_HELM** - Hide equipment
- **CF_ALLOW_DUEL_INVITES** - Allow duel invites
- **CF_ALLOW_TRADE_INVITES** - Allow trade invites
- **CF_ALLOW_GROUP_INVITES** - Allow group invites
- And many more...
## Experience System
```go
// Add adventure XP
if player.AddXP(1000) {
// Player may have leveled up
if player.GetLevel() > oldLevel {
// Handle level up
}
}
// Add tradeskill XP
player.AddTSXP(500)
// Check XP status
if player.AdventureXPEnabled() {
currentXP := player.GetXP()
neededXP := player.GetNeededXP()
}
// Calculate XP from kills
victim := &entity.Spawn{...}
xpReward := player.CalculateXP(victim)
```
## Currency Management
```go
// Add coins
player.AddCoins(10000) // Add 1 gold
// Remove coins (with validation)
if player.RemoveCoins(5000) {
// Transaction successful
}
// Check coin amounts
copper := player.GetCoinsCopper()
silver := player.GetCoinsSilver()
gold := player.GetCoinsGold()
plat := player.GetCoinsPlat()
// Validate sufficient funds
if player.HasCoins(1000) {
// Player can afford the cost
}
```
## Combat System
```go
// Enter combat
player.InCombat(true, false) // Melee combat
// Enter ranged combat
player.InCombat(true, true) // Ranged combat
// Exit combat
player.StopCombat(0) // Stop all combat
// Process combat (called periodically)
player.ProcessCombat()
// Check combat state
if player.GetInfoStruct().GetEngageCommands() != 0 {
// Player is in combat
}
```
## Spell Management
```go
// Add spell to spell book
player.AddSpellBookEntry(spellID, tier, slot, spellType, timer, true)
// Check if player has spell
if player.HasSpell(spellID, tier, false, false) {
// Player has the spell
}
// Get spell tier
tier := player.GetSpellTier(spellID)
// Lock/unlock spells
player.LockAllSpells()
player.UnlockAllSpells(true, nil)
// Manage passive spells
player.AddPassiveSpell(spellID, tier)
player.ApplyPassiveSpells()
```
## Quest Integration
```go
// Get active quest
quest := player.GetQuest(questID)
// Check quest completion
if player.HasQuestBeenCompleted(questID) {
count := player.GetQuestCompletedCount(questID)
}
// Update quest progress
player.SetStepComplete(questID, stepID)
player.AddStepProgress(questID, stepID, progress)
// Check quest requirements
if player.CanReceiveQuest(questID, nil) {
// Player can accept quest
}
```
## Social Features
```go
// Manage friends
player.AddFriend("FriendName", true)
if player.IsFriend("SomeName") {
// Handle friend interaction
}
// Manage ignore list
player.AddIgnore("PlayerName", true)
if player.IsIgnored("SomeName") {
// Player is ignored
}
// Get social lists
friends := player.GetFriends()
ignored := player.GetIgnoredPlayers()
```
## Spawn Management
```go
// Check spawn visibility
if player.ShouldSendSpawn(spawn) {
// Send spawn to player
player.SetSpawnSentState(spawn, player.SPAWN_STATE_SENDING)
}
// Get spawn by player index
spawn := player.GetSpawnByIndex(index)
// Remove spawn from player view
player.RemoveSpawn(spawn, false)
// Process spawn updates
player.CheckSpawnStateQueue()
```
## Player Manager
```go
// Create manager
config := player.ManagerConfig{
MaxPlayers: 1000,
SaveInterval: 5 * time.Minute,
StatsInterval: 1 * time.Minute,
EnableValidation: true,
EnableEvents: true,
EnableStatistics: true,
}
manager := player.NewManager(config)
// Start manager
manager.Start()
// Add player
err := manager.AddPlayer(player)
// Get players
allPlayers := manager.GetAllPlayers()
zonePlayers := manager.GetPlayersInZone(zoneID)
player := manager.GetPlayerByName("PlayerName")
// Send messages
manager.SendToAll(message)
manager.SendToZone(zoneID, message)
// Get statistics
stats := manager.GetPlayerStats()
```
## Database Integration
The system provides interfaces for database operations:
```go
type PlayerDatabase interface {
LoadPlayer(characterID int32) (*Player, error)
SavePlayer(player *Player) error
DeletePlayer(characterID int32) error
LoadPlayerQuests(characterID int32) ([]*quests.Quest, error)
SavePlayerQuests(characterID int32, quests []*quests.Quest) error
// ... more methods
}
```
## Event System
```go
type PlayerEventHandler interface {
OnPlayerLogin(player *Player) error

## Thread Safety
All player operations are thread-safe using appropriate synchronization:
- **RWMutex** for read-heavy operations (spawn maps, quest lists)
- **Atomic operations** for simple flags and counters
- **Channel-based communication** for background processing
- **Proper lock ordering** to prevent deadlocks
## Integration with Other Systems
The player system integrates with:
- **Entity System** - Players extend entities for combat capabilities
- **Spell System** - Complete spell casting and effect management
- **Quest System** - Quest tracking and progression
- **Skill System** - Skill advancement and bonuses
- **Faction System** - Reputation and standings
- **Title System** - Character titles and achievements
- **Trade System** - Player-to-player trading
- **Housing System** - House ownership and access
## Performance Considerations
- **Efficient spawn tracking** with hash maps for O(1) lookups
- **Periodic processing** batched for better performance
- **Memory-efficient data structures** with proper cleanup
- **Background save operations** to avoid blocking gameplay
- **Statistics collection** with minimal overhead
## Migration from C++
This Go implementation maintains compatibility with the original C++ EQ2EMu player system while providing:
- **Modern concurrency** with goroutines and channels
- **Better error handling** with Go's error interface
- **Cleaner architecture** with interface-based design
- **Improved maintainability** with package organization
- **Enhanced testing** capabilities
## TODO Items
The conversion includes TODO comments marking areas for future implementation:
- **LUA integration** for scripting support
- **Advanced packet handling** for client communication
- **Complete database schema** implementation
- **Full item system** integration
- **Group and raid** management
- **PvP mechanics** and flagging
- **Mail system** implementation
- **Appearance system** completion
## Usage Examples
See the individual file documentation and method comments for detailed usage examples. The system is designed to be used alongside the existing EQ2Go server infrastructure with proper initialization and configuration.
