X, Y and Z coordinate on a Minecraft map.

Coordinates numerically represent your location in a Minecraft world. They are based on a grid where three lines or axes intersect at the origin point. Players initially spawn within a couple hundred blocks of the origin point.

• the x-axis indicates the player's distance east (positive) or west (negative) of the origin point—i.e., the longitude,
• the z-axis indicates the player's distance south (positive) or north (negative) of the origin point—i.e., the latitude,
• the y-axis indicates how high or low (from 0 to 255, with 64 being sea level) the player is—i.e., the elevation,

thereby forming a right-handed coordinate system (thumb≡x, index≡y, middle≡z), making it easy to remember which axis is which.

Additionally, the f number in the debug screen tells you which direction the player is currently facing. 0 equals due south. Thus:

• 0 = South
• 1 = West
• 2 = North
• 3 = East

Displaying coordinates

Pressing F3 (or Fn + F3 on Macs and some laptops) brings up a debug screen with various data—including your current coordinates, at the top left of the screen. On new Macs, however, the Fn + F3 keystroke does not display coordinates. Use Alt + Fn + F3 instead.

Coordinates first appeared on the debug screen in Alpha 1.2.3.

On Console Edition the coordinates can be found on any map item.

Interpreting coordinates

The origin point marks the zero point for the x and z coordinates. Hence, it may be thought of as the 0,0 coordinate:

• x-axis = 0
• z-axis = 0

As you travel south, the z-axis number increases; travel north and it decreases. Similarly, the x-axis number increases as you travel east and decreases as you travel west.

One coordinate number equals one block. And, in terms of real-world measurement, one block equals 1 cubic meter.

As your elevation rises, the y-axis number increases, and as your elevation lowers, that number decreases.

The y coordinate works a bit differently than the x and z coordinates in terms of spawning. Typically, you do not spawn at y-coordinate 0. Instead, y=63 is the overworld water sea level, y 31 is the Nether lava sea, and y 11 is the overworld lava flood sea. To clarify: When the display shows your Y=63, then your feet are at Y=63, your legs are approximately 63.5 and your eyes are at 64.62, and you are out of the water; when the display shows your Y=62, then your head is in the Y=63+ block, your feet are in the Y=62 block, your feet may be wet and your head is dry. The top of the water is Y=63 (actually, slightly higher than Y=62.9). For Lava, the top of the overworld lava is 11, and if your Y is 10 then your feet may be burning.

With these numbers in mind, we can see that the player's debug screen above locates him or her at (ignoring the numbers after the decimal point for simplicity):

• x: 69 = 69 east
• y: 153 = 153 above the bottom of the game environment
• z: 45 = 45 south
• f: 3 = facing east.

座標の使用法

座標はさまざまな用途に使用できる。

プレイヤーが拠点を確立すると、探索を始める前に座標をメモする必要がある。死んで、リスポーンすると、その座標に向かって歩くと、拠点に戻ることができる。また、クリエイティブでコマンドブロックを取得し、その中に座標を入れることができる。コマンドブロックに書いた座標に一致する場所に移動することができる。

シード値を共有して物を見つけるため場所を指示するときに、座標がよく使われる。
