This command locks the player's camera to a specified entity, similar to how you click an entity in spectator mode. This can be used to, for example, force the player to watch a set of animation following an invisible entity. Note (Important!): - This works in any gamemode, even outside of spectator. - The player cannot unlock the camera themselves unless they re-login, or use the /unspectate command- It only moves the player's camera, the player position remains unchanged - The client cannot load new chunk as the player position is not changed. |

| /unspectate /unspectate |
This is the opposite of the /spectate command, unlocking the player's camera. | Op Level 2 |
| /where |
Tells the XYZ Coordinates of the player | Op Level 2 |
