Usage Examples

Basic Bot Auction Cycle

// Update cycle (every 60 seconds)
if (sBotAuctionMgr->IsEnabled()) {
    // Update status
    sBotAuctionMgr->UpdateBotAuctionStatus(bot);

    // Cancel unprofitable
    sBotAuctionMgr->CancelUnprofitableAuctions(bot);

    // Scan market (20% chance)
    if (urand(0, 100) < 20) {
        uint32 ahId = sBotAuctionMgr->GetAuctionHouseIdForBot(bot);
        sBotAuctionMgr->ScanAuctionHouse(bot, ahId);
        sBotAuctionMgr->AnalyzeMarketTrends(bot);
    }

    // List items
    ListItemsForSale();

    // Execute flips
    if (sBotAuctionMgr->IsMarketMakerEnabled())
        ExecuteFlipOpportunities();
}

GM Commands (Example)

// .bot auction scan
sBotAuctionMgr->ScanAuctionHouse(bot, ahId);

// .bot auction stats
AuctionHouseStats stats = sBotAuctionMgr->GetBotStats(bot->GetGUID());
handler->PSendSysMessage("Net Profit: %lld", stats.NetProfit);

// .bot auction flip
auto opportunities = sBotAuctionMgr->FindFlipOpportunities(bot, ahId);
for (auto& opp : opportunities)
    handler->PSendSysMessage("Item %u: Profit %llu (%.1f%%)",
        opp.ItemId, opp.EstimatedProfit, opp.ProfitMargin);

Economy Balance Recommendations

Live Servers

• Disable MarketMakerEnabled (prevents manipulation)
• Set MaxActiveAuctions = 5
• Set MinProfit = 50000 (5 gold)
• Use CONSERVATIVE or SMART_PRICING strategy

Single-Player Servers

• Enable MarketMakerEnabled (provides market activity)
• Set MaxActiveAuctions = 20
• Set MinProfit = 10000 (1 gold)
• Use SMART_PRICING strategy

Testing Environments

• Enable all features
• Reduce scan intervals for faster testing
• Increase MaxActiveAuctions for stress testing

Known Limitations

1. Price History Persistence: Optional - requires database tables
2. Cross-Realm Support: Limited to faction-specific AH
3. Quality Tiers: Basic support (5-star system not fully integrated)
4. Warband Integration: Not yet implemented (future enhancement)

Future Enhancements (Roadmap)

1. Crafting Integration

   • Crafting order fulfillment
   • Material cost analysis
   • Quality-based pricing

2. Machine Learning

   • Price prediction models
   • Demand forecasting
   • Optimal listing time detection

3. Advanced Analytics

   • Cross-faction arbitrage
   • Guild economy tracking
   • Server-wide economic reports

4. Warband Features (WoW 11.2)

   • Cross-character gold sharing
   • Warband bank integration
   • Shared auction access

Support & Troubleshooting

Common Issues

Issue: Bots not creating auctions

• Solution: Check Playerbot.Auction.Enable = 1, verify sellable items, check MaxActiveAuctions limit

Issue: No flip opportunities

• Solution: Enable MarketMakerEnabled, increase MaxRiskScore, ensure market scan ran recently

Issue: High CPU usage

• Solution: Increase UpdateInterval and MarketScanInterval, reduce PriceHistoryDays
