Screenshot showing the debug information

The debug information from Indev, Infdev, and early Alpha.

El Modo Debug se activa cuando pulsamos la tecla F3 o Fn+F3 en la mayoría de ordenadores portátiles. Muestra los datos de los chunks, el uso de la memoria, las coordenadas del jugador y muchas otras medidas como los Frames Per Second (FPS). Puede ser muy útil para decirle a otros jugadores la posición y ver el rendimiento del juego.

History

Indev
		The debug screen only had what we recognize as "the top part with all the numbers". This debug screen was not activated with F3, but as a toggle in the options.
Alpha
1.1.0		The debug screen was no longer listed as an option and required F3 to be held down to activate.
1.2.3		The coordinates were added to the debug screen.
Beta
1.3		The debug screen, along with other function key controls, became a toggle.
		When the debug screen was open, it would show numbers above every mob; these numbers being the mob's Entity ID. These were visible through blocks, making F3 a very useful mob-finder.
1.7		The "f" coordinate was made visible in the debug screen (facing direction).
1.8		The ability to see the level's seed was added.
		Removed entity numbers being shown above mob's head. Some players felt that it was cheating and that it took away from the game.
Lanzamiento oficial
1.2.1	1.2.0pre	Information about the biome and light level of the player's location were added. The seed in multiplayer was made hidden, showing as "0".
1.2.4		Pressing F3 (Fn+F3 on Mac and some laptops) brings up the debug screen but without the graphs. The graph will appear on pressing ⇧ Shift+ F3 (Fn+ ⇧ Shift + F3 on Mac and some laptops).
1.3.1	12w18a	Information about the player's speed and whether the player is touching the ground were added.
		Coordinates are now rounded to 5 digits.
	12w21a	Information about the world's seed was removed, seen instead by pressing the chat key and typing "/seed".
1.4.2	12w39a	Fl, x and z chunk coordinates, and more rotation (f) information were added.
	12w41a	Shift+F3 now shows the profiler graph.
Próximamente
1.8	14w02a	Now shows which axis you are facing after the cardinal direction: "Towards positive/negative X/Z".
	14w04a	The crosshair will display 3 short colored lines to indicate the direction of each axis: x/red, y/green, z/blue.
		The x coordinate line will now be bold when looking east/west, similarly the z coordinate line will now be bold when looking south/north.
	14w05a	Text now has a background.
		Replaced x, y, z, b, bl and other labels with more understandable labels.
		"Light" is now the light levels at feet, not eyes.
	14w06a	X, Y, and Z title has been changed from 'Feet' in the previous snapshot, to 'XYZ'.
		Day counter added, which increases by 1 every dawn.
		Now displays difficulty: Peaceful- 0.00, Easy- 0.75, Normal- 1.50, Hard 2.25 (but numbers slowly increase the longer you are in an area).
		Now displays player rotation in degrees and quadrants.
	14w11a	On the right hand side, a display shows up if you are looking at a block, showing its ID and block states.
	14w17a	All blocks now have their info displayed on the right hand side of the F3 debug screen.
		Removed the "Facing negative/positive x/z" from the F3 menu.
	14w20a	Readded "Facing negative/positive x/z".
	14w25b	F3 + B now also shows which direction entities are looking in using a blue line.
		Removed the line on the right-hand side which had displayed the name of the block model the player was looking at.
	14w29a	A 'Reduced Debug Info' toggle now exists within multiplayer settings to enable/disable reduced information on the debug screen.
		The reducedDebugInfo gamerule allows you to enable/disable reduced information on the debug screen. This overrides all 'reduced debug info' settings in clients.
	14w30a	Now displays how many chunk sections are being rendered currently and how many chunk sections are out of view in percent, the OpenGL version, display size, vendor and GPU.
		"Vanilla" added to the version number.

Trivia

• Lc, Biome, and the lighting values do not display when you are in the void or above y = 255 (in the Overworld)

• When triggered in the nether, the "B" (biome) displays the biome of "Hell". In The End, until release 1.8 (snapshot 14w17a) it indicated the biome "Sky", likely because The End was originally going to be the Sky Dimension.

• When used in a chunk that was created prior to Alpha 1.2(when there were no biomes), the B field will read "Ocean".

• Deeper into the profiler (Shift+F3), some tasks will have numbers higher than 9 and can't be accessed. Pressing the two keys simultaneously will not open the task.
