<p>我的世界服务器用的是TCP协议，通信使用的是<i>包</i>.
数据包是通过TCP协议连接发送的字节序列。 包的内容取决于包的ID和包的连接状态。每个连接的初始状态是 <a href="#Handshaking">握手包(Handshaking)</a>交换包的状态<a href="#Handshake">握手包(Handshake)</a> 和 <a href="#Login_Success">登陆成功</a>.

<h3><span class="mw-headline" id="Data_types">数据类型</span></h3>
<p>通过网络发送发的所以数据 (除了 VarInt 和 VarLong) 是 <a href="http://en.wikipedia.org/wiki/Endianness#Big-endian" class="extiw" title="wikipedia:Endianness">big-endian</a>,
that is the bytes are sent from most significant byte to least
significant byte. The majority of everyday computers are little-endian,
therefore it may be necessary to change the endianness before sending
data over the network.

<p>Identifiers are a namespaced location, in the form of <code>minecraft:thing</code>. If the namespace is not provided, it defaults to <code>minecraft</code> (i.e. <code>thing</code> is <code>minecraft:thing</code>. Custom content should always be in its own namespace, not the default one. The namespace should only use the characters <code>0123456789abcdefghijklmnopqrstuvwxyz-_</code>; actual names may contain more symbols.

<p>Variable-length format such that smaller numbers use fewer bytes. These are very similar to <a rel="nofollow" class="external text" href="http://developers.google.com/protocol-buffers/docs/encoding#varints">Protocol Buffer Varints</a>:
the 7 least significant bits are used to encode the value and the most
significant bit indicates whether there's another byte after it for the
next part of the number. The least significant group is written first,
followed by each of the more significant groups; thus, VarInts are
effectively little endian (however, groups are 7 bits, not 8).
</p><p>VarInts are never longer than 5 bytes, and VarLongs are never longer than 10 bytes.

Note that Minecraft's VarInts are not encoded using Protocol Buffers;
it's just similar. If you try to use Protocol Buffers Varints with
Minecraft's VarInts, you'll get incorrect results in some cases. The
major differences:
</p>
<ul><li>Minecraft's VarInts are all signed, but do not use the ZigZag encoding. Protocol buffers have 3 types of Varints: <code>uint32</code> (normal encoding, unsigned), <code>sint32</code> (ZigZag encoding, signed), and <code>int32</code> (normal encoding, signed). Minecraft's are the <code>int32</code>
variety. Because Minecraft uses the normal encoding instead of ZigZag
encoding, negative values always use the maximum number of bytes.</li>
<li>Minecraft's VarInts are never be longer than 5 bytes and its
VarLongs will never be longer than 10 bytes, while Protocol Buffer
Varints will always use 10 bytes when encoding negative numbers, even if
it's an <code>int32</code>.</li></ul>

<h3><span class="mw-headline" id="Position">Position</span></h3>
<p>64-bit value split in to three parts
</p>
<ul><li> x: 26 MSBs</li>
<li> z: 26 LSBs</li>
<li> y: 12 bits between them</li></ul>
<p>Encoded as followed:
</p>
<pre>((x & 0x3FFFFFF) << 38) | ((y & 0xFFF) << 26) | (z & 0x3FFFFFF)
</pre>
<p>And decoded as:
</p>
<pre>val = read_unsigned_long();
x = val >> 38;
y = (val >> 26) & 0xFFF;
z = val << 38 >> 38;
</pre>
<p>Note: The details of bit shifting are rather language dependent; the
above may work in Java but probably won't in other languages without
some tweaking. In particular, you will usually receive positive numbers
even if the actual coordinates are negative. This can be fixed by adding
something like the following:
</p>
<pre>if x >= 2^25 { x -= 2^26 }
if y >= 2^11 { y -= 2^12 }
if z >= 2^25 { z -= 2^26 }
</pre>
<h3><span class="mw-headline" id="Fixed-point_numbers">Fixed-point numbers</span></h3>
<p>Some fields may be stored as <a rel="nofollow" class="external text" href="https://en.wikipedia.org/wiki/Fixed-point_arithmetic">fixed-point numbers</a>,
where a certain number of bits represents the signed integer part
(number to the left of the decimal point) and the rest represents the
fractional part (to the right). Floating points (float and double), in
contrast, keep the number itself (mantissa) in one chunk, while the
location of the decimal point (exponent) is stored beside it.
</p><p>Essentially, while fixed-point numbers have lower range than
floating points, their fractional precision is greater for higher
values. This makes them ideal for representing global coordinates of an
entity in Minecraft, as it's more important to store the integer part
accurately than position them more precisely within a single block (or
meter).
</p><p>Coordinates are often represented as a 32-bit integer, where 5 of
the least-significant bits are dedicated to the fractional part, and
the rest store the integer part.
</p><p>Java lacks support for fractional integers directly, but you can
represent them as integers. To convert from a double to this integer
representation, use the following formulas:
</p>
<pre> abs_int = (int)double * 32.0D;
</pre>
<p>And back again:
</p>
<pre> double = (double)abs_int / 32.0D;
