αβspeedrun

A challenge starts with the itemspeedrun start command, where players pick a difficulty from built-in levels or from extended ones that appear as command suggestions. The goal decides which items must be collected and how complicated the target can become, and a player who reaches every goal in the set wins. Typing itemspeedrun stop ends or pauses a running challenge. Goals are identified by IDs. The SpeedABC series uses IDs such as speedabc:a, speedabc:b and speedabc:c, each asking for items whose names begin with a given letter. A data pack can define new goal sets, so server owners and map makers can shape the challenge without changing code.

The mod also includes an experimental multiplayer mode. A player can invite others with itemspeedrun invite, then set up a cooperative game through a draft: itemspeedrun draft create, itemspeedrun draft setplaytype coop, itemspeedrun draft setgoal, and itemspeedrun draft submit. Players are then invited, and the challenge starts after they accept. The mod requires Architectury API and Fabric API. A server running it needs every connecting player to have it too. Builds are published for Fabric, Forge and Quilt, and the latest file targets 1.20.1. The mod is open source under the GNU Affero General Public License v3.0 only.
