Carpet ROF Addition

ROF Carpet Addition is an extension for Carpet that focuses on reducing lag in technical Minecraft servers without breaking normal gameplay, while adding some quality-of-life features.

This mod follows the Carpet style: features are implemented as gamerules that can be enabled, disabled, or tuned individually. Under the default configuration, vanilla behavior is not changed.

Main features include:

• Ender pearl cannon optimizations: aggressive TNT merging, more stable pearl chunk loading, and optimized raycast (assuming naturally generated blocks’ height stays under a threshold). With all optimizations enabled, average MSPT from pearl launch to landing is reduced by 80%–95%; for very large cannons (>5000 TNT), lag can drop by two orders of magnitude.

• Intelligent packet limiting: restricts packet sending from specific entities in certain areas without affecting normal survival, reducing network and client lag. Used for large-scale sand duplicators and mob farms.

• Asynchronous world ticking optimizations(1.5+): caches the chunk lists used by random ticks and natural mob spawning, and supports asynchronously precomputing candidates for the next game tick. When asynchronous results are unavailable or outdated, the mod automatically falls back to vanilla behavior.

• High-density entity collection optimizations(1.5+): uses a section-based spatial index to optimize Lithium's entity-pushing candidate collection, reducing the cost of processing large numbers of entities in a small area.

• More detailed permission control: by directly modifying the vanilla command tree, finer-grained permission control can be achieved—for example, independently controlling permissions for individual subcommands.

• Other small utilities are also included.
