Understudy is an addon for Minecraft Bedrock Edition that allows you to spawn and control simulated players. Simulated players are entities that can be controlled by commands, but otherwise act almost exactly like normal players.
Important
This addon is a Canopy Extension, which means Canopy must be installed in your world for it to work.
Canopy can be downloaded here: https://github.com/ForestOfLight/Canopy
All commands are prefixed with ./. The ./player command can be abbreviated to ./p. The player command is disabled until enabled with the commandPlayer rule. Do ./help for more information.
