ChatPositionDisplay

This is a mod that can display the current player's coordinates, block coordinates, and the corresponding Nether coordinates of the current player's block coordinates in the chat box, and it has been open-sourced on GitHub.

When you install this mod and open the chat box, the mod will display the coordinates above the game screen. In addition, you can switch the display mode of the current coordinates, copy the coordinates, and copy the coordinates to the chat box.

Furthermore, you can copy the current coordinates or the current block coordinates by pressing Alt+C or Alt+X, inspired by the coordinate display UI in Minecraft Bedrock Edition.

Note: This mod will display coordinates both in the chat box and when the player is sleeping. If you do not want the coordinates to be displayed when the player is sleeping, you can modify the bedChat option in the cpd-config.json file located in the config directory of the game directory to set whether the coordinates should be displayed when the player is sleeping.
