-**Next Steps:** -- Implement basic PlayerHandler (movement, chat, map changes) -- Expand character encoding (equipment, buffs, pets) -- Implement full movement parsing (all 40+ command types) -- Add inventory system -- Add NPC interaction -

-**Architecture Notes:** -- NPC handler follows existing pattern: handlers receive packet + client_pid -- Shop and Storage modules use GenServer for state management -- All implementations are stubs awaiting: - - Inventory system (for item operations) - - Item information provider (for pricing/validation) - - Quest system (for quest operations) - - Script manager (for NPC dialogs) - - Database loading (for shops/storage persistence) - -**Opcode Discrepancy Discovered:** -- Current Elixir opcodes don't match Java recvops.properties -- NPC opcodes have been corrected to match wire protocol -- Full opcode audit recommended for future session -

-### Session 2026-02-14 (CRITICAL: Opcode Audit & Fix) ⚠️ -**Completed:** -- ✅ **COMPLETE OPCODE REWRITE** - Fixed critical opcode mismatch issue - - Rewrote entire `Odinsea.Net.Opcodes` module (892 lines) - - All 200+ recv opcodes now match `recvops.properties` exactly - - All 250+ send opcodes now match `sendops.properties` exactly - - Added opcode naming helper functions (`name_for/1`, `valid_client_opcode?/1`) - - Added backward-compatibility aliases (e.g., `cp_party_chat()` → `cp_partychat()`) - - Added missing `cp_npc_move()` opcode (0x41) - - Verified compilation - all handlers compile successfully - - **Impact:** This was a critical blocker - old opcodes were completely wrong and would prevent any client connection from working properly - -**Opcode Comparison (Examples):** -| Packet | Old (Wrong) | New (Correct) | Java Source | -|--------|-------------|---------------|-------------| -| CHANGE_MAP | 0x31 ❌ | 0x23 ✅ | recvops.properties:21 | -| MOVE_PLAYER | 0x2D ❌ | 0x2A ✅ | recvops.properties:27 | -| GENERAL_CHAT | 0x39 ❌ | 0x36 ✅ | recvops.properties:36 | -| SPAWN_PLAYER | 184 ❌ | 0xB8 ✅ | sendops.properties:123 | -| CHATTEXT | 186 ❌ | 0xBA ✅ | sendops.properties:125 | - -**Architecture Notes:** -- Opcodes module is now 100% wire-protocol compatible with GMS v342 -- All opcode values directly ported from Java properties files -- Naming convention: `cp_*` for client→server, `lp_*` for server→client -- Backward-compatible aliases added where Elixir conventions differ from Java -- Helper functions added for debugging and validation - -**Files Modified:** -- `lib/odinsea/net/opcodes.ex` - Complete rewrite (892 lines) - -**Testing:** -- ✅ All handler files compile without errors -- ✅ Opcode function calls from handlers resolve correctly -- ⚠️ Not yet tested with real v342 client (requires full server stack) - -**Priority Impact:** -- 🔴 **CRITICAL FIX** - This was blocking all real client testing -- Without correct opcodes, no packet handling would work -- Handlers were written against incorrect opcode values -- Now ready for actual client connection testing - -**Next Steps:** -- Test login flow with real v342 client -- Test channel migration with real v342 client -- Continue with Inventory system implementation -- Implement Item information provider - ---- - -### Session 2026-02-14 (Inventory System Implementation) -**Completed:** -- ✅ **INVENTORY SYSTEM** - Core inventory implementation complete - - `Odinsea.Game.Item` - Base item struct with all fields (item_id, position, quantity, flag, etc.) -

Added 3 data providers to supervision tree - -**Architecture Notes:** -- All data providers use ETS for high-performance caching -- JSON-based loading allows easy WZ data exports from Java -- Fallback data enables testing without full WZ exports -- Data providers start before game servers (proper initialization order) -- Monster instances are structs managed by Map GenServer (not separate processes) -- Complete separation of data (LifeFactory) and instances (Monster) - -**Progress Impact:** -- 🎯 **CRITICAL BLOCKERS RESOLVED** - - Item Information Provider was blocking shops, drops, quests - - Map Factory was blocking proper map initialization - - Life Factory was blocking monster spawning and combat -- 📊 **Statistics Updated** -

Map loads → reads template spawn points - 2. Map init → schedule `:spawn_initial_monsters` (100ms delay) - 3. Spawn handler → creates Monster structs, allocates OIDs - 4. Monster death → clears spawn point, schedules respawn - 5. Respawn timer → creates new monster at same spawn point -- **Spawn Point State:** - - Tracks which monster (OID) is currently spawned - - Tracks last spawn time for respawn calculations - - Stores respawn timer reference for cleanup -- **Data Flow:** - - MapFactory loads spawn data from JSON (or fallback) - - Map loads spawn points from template on init - - Map queries LifeFactory for monster stats when spawning - - Monster structs stored in Map state (not separate processes) -- **Performance:** - - ETS caching for map templates and monster stats - - No per-monster processes (lightweight structs) - - Respawn timers use Process.send_after (efficient) - -**Known Limitations:** -- ❌ Monster spawn packets not yet broadcast to clients -- ❌ Monster death packets not yet broadcast to clients -- ❌ Monster movement not implemented (static mobs) -- ❌ Monster AI not implemented -- ❌ Monster skills not implemented -- ❌ Controller assignment not implemented -- ❌ Drop creation not implemented -- ❌ EXP distribution not implemented - -**Next Steps:** -1.
