Overview

Lazy AI dynamically reduces the frequency and precision of mob AI calculations based on their distance from players. Mobs close to players behave normally, while those farther away update their goals, pathfinding, and other goals less often. This ensures smoother performance, especially in mob-heavy worlds.

Lazy AI bases its distance calculations of the simulation distance * distance scaling of your game

Performance difference

Vanilla performance

Using AI Optimization Type 'Dynamic' will dynamically switch between the three optimization modes based on TPS

Lazy AI performance (using AIOptimizationType = Minimal)

Lazy AI performance (using AIOptimizationType = Moderate)

Lazy AI performance (using AIOptimizationType = Aggressive)

Features

• Distance-based AI scaling | Reduces AI updates for mobs that are far from players
• Pathfinding optimization | Simplifies A* path calculations at long distances
• Reduced goal frequency | Look, wander, and tempt goals run less often when distant
• Configurable behavior | Easily balance performance and gameplay through a simple config accessible through mod menu
• Server-wide improvement | Decreases tick load even on servers

Settings

• AI Optimization Type | This settings controls how aggressive the optimizations should be
• Distance Scaling | This setting controls what % range of your simulation distance is considered close and far range
• Mob Tempting Delay | This setting controls how much delay animals have to being tempted by an item
• Disable Zombie Egg Stomping | This setting controls the prevention of zombies wanting to destroy turtle eggs

Available from version 1.3.2+

• Never Slow Down Distant Mobs | This setting controls if distant mobs should never slow down. Enabling this reduces the mod's TPS-boosting effect on your game, but will fix large (multiple chunks large) mob farms slowing down production.
