## 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 _Lower ms -> better (target: 50ms or lower per tick)_ ### Vanilla performance

### Lazy AI performance **Using AI Optimization Type 'Dynamic' will dynamically switch between the three optimization modes based on TPS** | Minimal | Moderate | Agressive | | ------------- | ------------- | ------------- | | Lazy AI performance (using AIOptimizationType = Minimal)

## 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](https://modrinth.com/mod/modmenu)* - **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* - **Enable Vanilla Mob Ticking (Previously: Never Slow Down Distant Mobs)** | *This setting controls if distant mobs should tick the same as in a unmodded (vanilla) game. Enabling this reduces the mod's TPS-boosting effect on your game, but can fix mob ticking issues.* Lazy AI settings menu

## FAQ ### Can this mod increase my TPS? Yes, this mod can improve your TPS. ### Can this mod increase my FPS? No, this mod cannot improve your FPS. ### Why does the dynamic optimization mode not target below 50ms? Minecraft runs on a 50ms tick cycle (20 TPS). If the (local) server processing finishes in under 50ms, the game waits for the remaining time. Consequently, any optimization below 50ms yields no increase in normal tick speed. The mod focuses on keeping tick times from exceeding 50ms, as higher values cause entities to move in slow motion. The heavier the (local) server load, the more aggressively the dynamic mode intervenes to maintain 50ms. When the (local) server runs smoothly, the mod scales back its intervention. ### Does this mod affect mob farms? Short awnser: Yes, but only a little bit. Long awnser: Yes, LazyAI does affect mob farm efficiency, but the throughput impact is minimal. In testing with my iron golem farm, vanilla Minecraft yielded 1023 iron ingots, while with the LazyAI on the aggressive setting yielded 979 iron ingots. That's a difference of ~4.5%. A few things worth noting: - This was tested on the aggressive setting, which has the most impact. Using a less aggressive setting will reduce that gap further. - A ~4.5% decrease is unlikely to be noticeable in normal gameplay. - Results may vary depending on farm design and server performance. - The testing were done on LazyAI version 1.6.0. In practice, you won't notice the mob farm efficiency decrease. ### What modloader do I need? You need Fabric ### I installed the mod, but didn't see as much difference? The preview images are taken in a stress test situation. It can also be because your simulation distance or this mods *distance scaling* is set too high for your use case. ### Where is the config located? .minecraft/config/lazy-ai.json ### Can this mod be used on a server? Yes, you can use this mod on a server. The mod works on both the server and the client. Vanilla clients can join a server using LazyAI. ### Can this mod be used on a client? Yes, you can use this mod on a client. The mod works on both the server and the client. Clients with LazyAI can join servers without LazyAI. ### How does the AI Optimization Type and Distance Scaling work?
