What

Control Player is a server-side mod that allows players to swap control with another player or take control of Carpet fake players.

When a swap is active, the two players effectively control each other's bodies.The mod also works well with Carpet mod fake players, allowing real players to temporarily control them.

Why

This mod makes it possible to observe gameplay from another perspective useful when test mechanics using fake players.

Gamerules

showControllerPrefix

Default: false

When enabled, the name of the player currently controlling someone will be displayed ​after the player's name​.

This helps identify control relationships more easily, especially when multiple swaps are active.

---

permissionSwapsToo

Default: false

When enabled, ​player permissions will also be swapped together with the bodies​.

Normally, only the player control / body is swapped.
With this rule enabled, the permission level (such as OP level) will also be exchanged between the two players.

Warning:
This can be dangerous on servers, as it may temporarily grant elevated
permissions to another player.
