Totally Accurate Mob Battle Simulator

Press M to enter the battle mode. Inside it, the Play/Pause control freezes or resumes the scene, and holding the mouse wheel rotates the camera. Holding the left button runs time in slow motion and holding the right button runs it fast; placing and removing mobs only takes effect while the game is paused. The mod also changes some vanilla Minecraft settings while the mode is active.

The Mob Select tab lists mobs, and a button in the upper left corner bookmarks a specific mob. Left-click or drag to place mobs in the world and right-click or drag to remove them. Holding Left Ctrl deletes non-living entities. Search supports a mod ID prefix and a tag prefix. The Preset tab stores groups of mobs, and the Team tab assigns mobs to teams, creating a team on first use and defaulting to white when no color is given. The Mob Teleport controls let a player select a mob and then click a block to move it there.

The mod is published for Forge only, with a single build for 1.20.1 released on 2026-09-06. The server and every player need the mod installed. The code is not open source and is covered by All rights reserved, while the source code and issue tracker are publicly linked.
