Lokalib 4.6 — Major Changes

Lokalib 4.6 represents a significant architectural milestone, transforming the library from a utility toolkit into a fully modular, production-grade datapack framework. This version introduces a unified execution model, formalized APIs, and forward-compatible abstractions designed for long-term stability across Minecraft versions and platforms.

1. Unified Core Lifecycle

A fully standardized lifecycle system has been introduced, consisting of deterministic load, tick, and teardown phases. Initialization now includes version probing, capability detection, registry rebuilding, module activation, and system bootstrapping in a strict execution order. This ensures predictable behavior across reloads and environments.

2. Centralized Event Bus

A complete event-driven architecture replaces fragmented advancement and scoreboard-based triggers. The new event system provides:

• Priority-based handler execution
• Pre-dispatch filtering with zero-cost skips
• Event cancellation for override logic
• Built-in and custom event support This establishes a scalable and consistent interaction model for all datapacks.

3. Advanced Scheduler System

A native scheduler eliminates manual tick-based timing logic. It supports:

• Delayed execution
• Interval-based repetition
• Task cancellation via IDs
• Configurable per-tick execution limits The scheduler is optimized for performance and integrates directly with the event system.

4. Entity Abstraction Layer

Entities are now managed through a robust tracking system using unique IDs. New capabilities include:

• Persistent entity referencing across ticks
• Lifecycle hooks (spawn, tick, interact, damage, death)
• Group-based operations for batch processing
• Internal registry for metadata and ownership This enables reliable and scalable entity-driven mechanics.

5. Modular Architecture

Lokalib introduces a fully modular system with opt-in feature sets. Built-in modules (e.g., raycasting, GUI, physics, animation) can be dynamically activated, consuming zero resources when inactive. Third-party modules can integrate seamlessly through standardized lifecycle hooks.

6. Capability & Compatibility Layer

A major addition is the environment abstraction system:

• Automatic detection of Minecraft version and platform
• Feature flags for conditional logic
• API-level gating and fallback execution
• Version-independent wrapper functions This ensures forward compatibility and graceful degradation across versions and mod loaders.

7. Registry System

A generalized registry framework allows datapacks to define and manage structured data (items, abilities, GUIs, etc.) with:

• Namespaced isolation
• Cross-pack discoverability (optional)
• Persistent storage integration This replaces ad-hoc storage patterns with a standardized data model.

8. API Standardization

All public APIs now follow a strict input/output contract via storage and scoreboards. Additionally, macro function support enables cleaner syntax on supported versions while maintaining backward compatibility.

9. Performance Framework

System-wide performance guarantees have been formalized:

• Zero-cost idle subsystems
• Configurable tick budgets
• Lazy evaluation for heavy operations
• Scoreboard-first design for hot paths A built-in profiler provides subsystem-level performance insights.

10. Extras Integration Layer

Lokalib now includes native integration points for external extensions (Lokalib Extras). APIs automatically delegate to enhanced implementations when available, without changing their interface. This enables seamless upgrades from vanilla limitations to mod-powered features.

11. Debugging and Diagnostics

A structured logging and debugging system has been added, including:

• Persistent error logs
• Configurable log levels
• Real-time debug output
• Built-in performance profiling tools

12. Migration System

A version-aware migration framework ensures safe upgrades between versions. Data schemas, registries, and scoreboards are automatically updated without breaking existing worlds.

Lokalib 4.6 establishes a stable, extensible foundation for complex datapack development, shifting the focus from low-level implementation to high-level gameplay design.
