Debug mode



Debug Mode is a world type that contains all vanilla Minecraft blocks in all their different states in a single world folder in a grid across height y=70, with a barrier floor at y=60.

The world type is used to test block models, states and textures. It is thereby useful not only to Mojang but also to creators of resource packs.

To select the debug mode, the key has to be pressed down when the Customized world type is reached; the next world type will then be Debug Mode rather than Default.

The only game mode available is Spectator, and further options are disabled. Game mode can be changed from inside the world with console commands. Breaking blocks is possible: particle effects are shown, and the block is instantly replaced. Some blocks allow right click interactions (e.g. chests), while others don't (e.g. levers, redstone repeaters).

Issues
However, any issue with the debug world will be resolved as invalid due to the fact that despite the bugs in there, it should not be interacted with outside of Spectator mode.

Trivia

 * Every block creates only once. The rest of the map is empty.
 * The sun is displayed, but there is no day/night cycle. The daytime can be adjusted using console commands.
 * When a debug mode world is loaded in a previous Minecraft version, the loading screen will freeze.
 * When you try to go to The End, it will display the end credits.
