Debug screen



The debug screen is a screen that is triggered when the F3 key is pressed. It shows the chunk cache, the memory usage, various parameters, the player's map coordinates and a graph that measures latency. It can be very useful for telling other players your map location, checking for lag and various other purposes.

Legend:

Below these parameters, the player's map coordinates are displayed. The X and Z axis are both horizontal, and the Y axis is vertical, and the F axis is direction, from 0 to 3. At the bottom of the screen, a graph is displayed which measures latency. When you activate the debug screen, it also shows numbers above every mob. This is useful for finding mobs to kill. It is often used to find dungeons.

Bugs

 * If you exit to the main menu with the debug screen open, it will stay on the screen.
 * Opening a chest with the debug screen on turns the debugging area grey. The text does not turn grey, however. This will not crash the game.
