**Testing**: Focus testing on the UDP protocol layer and packet parsing, as these are critical for client compatibility. All systems include comprehensive test suites with concurrency testing for thread safety validation.
**Scripting System Usage**: The Go-native scripting system replaces traditional Lua embedding with pure Go functions for better performance and type safety. Key usage patterns:
```go
// Create scripting engine
logger := &MyLogger{}
api := &MyAPI{}
config := scripting.DefaultScriptConfig()
engine := scripting.NewEngine(config, api, logger)
// Register EQ2 functions
if err := scripts.RegisterEQ2Functions(engine); err != nil {
return fmt.Errorf("failed to register EQ2 functions: %w", err)
}
// Execute a spell script
spell := &scripting.ScriptSpell{ID: 123, Caster: player}
result, err := engine.ExecuteSpellScript("heal_spell", "cast", spell)
if err != nil || !result.Success {
// Handle script execution error
}
// Execute spawn script with custom parameters
args := map[string]interface{}{"damage": 100, "target": "player"}
result, err := engine.ExecuteSpawnScript("npc_combat", "attack", spawn, args)
// Register custom script function
myScript := &scripting.ScriptDefinition{
Name: "custom_spell",
Type: scripting.ScriptTypeSpell,
Functions: map[string]scripting.ScriptFunction{
"cast": func(ctx *scripting.ScriptContext) error {
// Access script context
caster := ctx.GetCaster()
target := ctx.GetTarget()
spellID := ctx.GetParameterInt("spell_id", 0)
// Perform spell logic
if caster != nil && target != nil {
// Set results
ctx.SetResult("damage_dealt", 150)
ctx.Debug("Cast spell %d from %s to %s",
spellID, caster.GetName(), target.GetName())
}
return nil
},
},
}
engine.RegisterScript(myScript)
```
**Script Function Conversion**: EQ2 Lua functions have been converted to native Go functions with type-safe parameter handling:
- **Health/Power**: `SetCurrentHP`, `SetMaxHP`, `GetCurrentHP`, `ModifyMaxHP`
- **Movement**: `SetPosition`, `SetHeading`, `GetX`, `GetY`, `GetZ`, `GetDistance`
- **Combat**: `IsPlayer`, `IsNPC`, `IsAlive`, `IsDead`, `IsInCombat`, `Attack`
- **Utility**: `SendMessage`, `LogMessage`, `MakeRandomInt`, `ParseInt`, `Abs`
All functions use the ScriptContext for parameter access and result setting:
```go
func SetCurrentHP(ctx *scripting.ScriptContext) error {
spawn := ctx.GetSpawn()
hp := ctx.GetParameterFloat("hp", 0)
// Implementation...
ctx.Debug("Set HP to %f for spawn %s", hp, spawn.GetName())
return nil
}
```
## Development Patterns and Conventions
**Package Structure**: Each system follows a consistent structure:

# EQ2Go Event System
A simplified event-driven system for handling game logic without the complexity of a full scripting engine.
## Overview
The event system provides:
- Simple event registration and execution
- Context-based parameter passing
- 100+ built-in EQ2 game functions organized by domain
- Thread-safe operations
- Minimal overhead
- Domain-specific function organization
## Basic Usage
```go
// Create event handler
handler := NewEventHandler()
// Register all EQ2 functions (100+ functions organized by domain)
err := functions.RegisterAllEQ2Functions(handler)
// Create context and execute event
ctx := NewEventContext(EventTypeSpawn, "SetCurrentHP", "heal_spell").
WithSpawn(player).
WithParameter("hp", 150.0)
err = handler.Execute(ctx)
```
## Event Context
The `EventContext` provides:
- Game objects: `Caster`, `Target`, `Spawn`, `Quest`
- Parameters: Type-safe parameter access
- Results: Return values from event functions
- Logging: Built-in debug/info/warn/error logging
### Fluent API
```go
ctx := NewEventContext(EventTypeSpell, "heal", "cast").
WithCaster(caster).
WithTarget(target).
WithParameter("spell_id", 123).
WithParameter("power_cost", 50)
```
### Parameter Access
```go
func MyEvent(ctx *EventContext) error {
spellID := ctx.GetParameterInt("spell_id", 0)
message := ctx.GetParameterString("message", "default")
amount := ctx.GetParameterFloat("amount", 0.0)
enabled := ctx.GetParameterBool("enabled", false)
// Set results
ctx.SetResult("damage_dealt", 150)
return nil
}
```

## Function Organization
Access functions by domain using the `functions` package:
```go
import "eq2emu/internal/events/functions"
// Register all functions at once
handler := events.NewEventHandler()
err := functions.RegisterAllEQ2Functions(handler)
// Get functions organized by domain
domains := functions.GetFunctionsByDomain()
healthFunctions := domains["health"] // 23 functions
combatFunctions := domains["combat"] // 36 functions
movementFunctions := domains["movement"] // 27 functions
// ... etc
```
## Custom Events
```go
// Register custom event
handler.Register("my_custom_event", func(ctx *events.EventContext) error {
spawn := ctx.GetSpawn()
if spawn == nil {
return fmt.Errorf("no spawn provided")
}
// Custom logic here
ctx.Debug("Custom event executed for %s", spawn.GetName())
return nil
})
// Execute custom event
ctx := events.NewEventContext(events.EventTypeSpawn, "my_custom_event", "trigger").
WithSpawn(someSpawn)
err := handler.Execute(ctx)
```
## Event Types
- `EventTypeSpell` - Spell-related events
- `EventTypeSpawn` - Spawn-related events
- `EventTypeQuest` - Quest-related events
- `EventTypeCombat` - Combat-related events
- `EventTypeZone` - Zone-related events
- `EventTypeItem` - Item-related events
## Thread Safety
All operations are thread-safe:
- Event registration/unregistration
- Context parameter/result access
- Event execution
## Performance
The event system is designed for minimal overhead:
- No complex registry or statistics
- Direct function calls
- Simple context passing
- Optional timeout support
