AI Improvements Mod (1.21.4, 1.20.1) – Performance & Logic Upgrades for Mod AIs

AI Improvements Mod (1.21.4, 1.20.1) is a simplified AI modification mod focused on performance and low-level modifications to AIs in the game. Picking up the slack for the base game and improving it for a modded ecosystem. Handling common problems such as too many animals, performance hits from swarms of zombies, and simply remove tasks skipped by larger AI improvement mods.

Features:

Config to disable AI Watch Closest Entity:

• By default, the config is set to false and will not do anything. When changed to true it will remove an AI segment called EntityAIWatchClosest. This AI segment handles the coded AIs use to rotate their head towards a nearby entity. Visually this will cause a few odd issues. However, for the CPU this frees up a lot of usages caused by entities.

Config to disable AI look random, config is not enabled by default:

• By default, the config is set to false and will not do anything. Setting the config to true will cause entities to no longer use the ‘look idle’ AI code. This can improve performance for servers will large populations. As almost every entity on the map will use this when not doing anything important. Visually this can cause the entities head to not rotate sometimes but mostly goes unnoticed.

Config to replace EntityLookHelper with a more efficient version, config is enabled by default:

• This is the main feature of the mod and can greatly improve CPU performance at a small cost to RAM. How this works is MC’s look helper code is replaced with a custom version. The custom version stores some data that makes it faster to get the angle for a location. Threw some testing with VisualVM result have shown a 50% to 80% decrease in CPU usage by the AI code. For a server with 25 people on constantly this resulted in again from 5 to 7 tsp.
