Lumenfuchs' Dummy is a proof-of-concept datapack/mod which adds a new entity: the Dummy. With unusual stalking behaviors and even weirder interactions with its environment, the Dummy is a presence that will not leave you at ease until it is gone.
The Dummy is a non-mob humanoid who mimicks entity-like behavior to its best capacity. It stares nearby players, and if not actively looked at, slowly approaches them.
If getting too close to a player, the Dummy performs its "attack" ability, causing skies to darken and mobs to anger towards that player. Even heavens itself turns against the victim, with thunders being redirected to smite the player.
Some methods of avoiding a Dummy's stalk include gaps in terrain, as it will avoid heights greater than one block, and strongly powered redstone. However, keeping one at bay might not last you too long...
All behaviors of the datapack are configurable in-game by running /trigger lumenfuchs.settings ; Customization, behavior and compatibility-affecting features may all be edited to the user's desire within a "settings panel" in chat.
Some older versions (most notably v1.1.1 and v1.2.0) may cause the datapack to stop working when upgrading on an existing world; On such cases, resetting that world's settings can fix these issues and restore the datapack's functionality:
