Class SharedConstants

java.lang.Object
net.minecraft.SharedConstants
public class SharedConstants extends Object
Shared global constants.

Note: The majority of the fields within this class are public static final with constant expressions (constants), and are inlined by the Java compiler at all places which reference these constant fields. Therefore, changing the value of these constant fields will have no effect on already compiled code.

In addition, it is presumed that a large portion of these constant fields (such as those prefixed with DEBUG_ are used as 'flags', for manually toggling code meant for use by Mojang developers in debugging. Therefore, optimizing compilers (which include the Java compiler) may omit the code hidden behind disabled flags, and will result in these flags having no apparent use in the code (when in reality, the optimizing compiler has removed the code which uses them).

    • RELEASE_NETWORK_PROTOCOL_VERSION

      @Deprecated public static final int RELEASE_NETWORK_PROTOCOL_VERSION
      Deprecated.
      Use getProtocolVersion() instead.
      The numeric format number for the networking protocol used by the release target of this game version.

      This protocol version is used when this game version is a release version, not a snapshots. For snapshots, see SNAPSHOT_NETWORK_PROTOCOL_VERSION.

      See Also:

    • SNAPSHOT_NETWORK_PROTOCOL_VERSION

      @Deprecated public static final int SNAPSHOT_NETWORK_PROTOCOL_VERSION
      Deprecated.
      Use getProtocolVersion() instead.
      The numeric format number for the networking protocol used by the snapshot of this game version.

      This protocol version is used when this game version is a snapshot version. For releases, see RELEASE_NETWORK_PROTOCOL_VERSION.

      The actual networking protocol version used in snapshot versions is the combination (bitwise OR) of this number and the bit at the position marked by SNAPSHOT_PROTOCOL_BIT.

    • DATA_VERSION_TAG

      public static final String DATA_VERSION_TAG
      The key for the NBT tag which contains the data version of some data, for use in datafixing.

      For various objects, their stored data in a CompoundTag will usually contain a IntTag indexed with this key, which stores the data version when the data for that object was written out. This is used by the datafixer system to determine which fixers needs to be applied to the data.

      public static final int TICKS_PER_SECOND
      The amount of game ticks within a real-life second.

      See Also:

    • TICKS_PER_GAME_DAY

      public static final int TICKS_PER_GAME_DAY
      The amount of game ticks within a game day. A game day is defined as 20 real-life minutes, so this is equal to TICKS_PER_MINUTE * 20. This falls under the same guarantees and restrictions as TICKS_PER_SECOND.
