EasyHologram API

The definitive server-side hologram framework for Minecraft 1.21 (Fabric). Engineered to construct floating text, blocks, and items using highly-optimized vanilla Display Entities. Zero network interference; maximum programmatic control.

Technical Specifications

🔤 Rich Output Geometries — Robust layouting for scalable strings, structural blocks, and items. Customize RGB backgrounds, drop shadows, and line widths dynamically.

🖱️ HCI Interaction — Map native operational logic to left and right-click intercept listeners attached to holograms.

📊 Multi-Line Support — Rapidly array, space, and organize complex vertical string data without recalculating individual vectors.

🔄 Placeholder Integration — Natively interfaces with PlaceholderAPI to stream real-time mutable statistics cleanly directly to active displays.

👁️ Visibility Matrices — Programmatic logic controlling packet broadcasting, dictating pinpoint player visibility filters for any display entity.

🎬 Kinematic Interpolation — Buttery-smooth visual transition sequences mapping 1.21 translation interpolation bounds.

💾 Fault-Tolerant State — Guaranteed auto-serialization via the engine's PersistentState, seamlessly ensuring server restart survivability.

Command Interface

Live operational commands strictly require parameter validation and operator rank (level 2+).

API Integration

Extensibility module available for downstream developers. Inject logic easily.

Standard Build Initialization
