Core Architecture & Performance
The most significant differences lie in how each engine handles internal processing and server resources.| Feature | MythicMobs (Legacy) | BTCMobs (Modern) |
|---|---|---|
| Language & Runtime | Java | Kotlin & JVM 21+ (Modern Optimizations) |
| Concurrency | Single-Threaded (Main) | Native Folia & Async Support (Region-Threaded) |
| Config Parsing | Synchronous (Blocking) | Background Thread Parallel Parsing |
| Math Engine | Standard Math | Optimized Vector Pools & Variable Math |
| Visuals | ArmorStands (High Traffic) | Display Entities (Zero Server Lag) |
Native Folia Support
Unlike legacy systems, BTCMobs is built for Advanced Slime Paper and Folia. It utilizes Region Schedulers to tick mobs in parallel across CPU cores. It literally cannot freeze your main thread because it doesn’t run solely on it.Feature Parity & Extensions
BTCMobs implements the entire MythicMobs feature set.Exclusive Features
BTCMobs extends the format with modern capabilities:- Display Entities: Native
displayBlock,displayItem,displayTextmechanics that use Packet-based Display Entities for ultra-smooth, low-bandwidth effects. - Formation AI: The
squadmechanic allows mobs to coordinate attacks or use group tactics. - Modern Components: Full Adventure Component support for all messages and items (MiniMessage).
- 1.21 Features: Native support for
windcharge(Breeze) andmaceattackmechanics and more…
Summary: Which to Use?
| Scenario | Recommendation |
|---|---|
| Legacy Version Support | MythicMobs (Supports versions older than 1.19/1.20) |
| Modern Performance | BTCMobs (Built for 1.21.11+ Paper/Folia) |
| Complex Visuals | BTCMobs (Display Entities save massive TPS) |
| High Player Counts | BTCMobs (Async/Region threading scales linearly with cores) |
This benchmarking reflects the strict 100% parity status achieved in January 2026.
