  displayName: { toString: Function }, // ChatMessage object.
  gamemode: 0,
  ping: 28,
  entity: entity // null if you are too far away
}

A player's ping starts at 0, you might have to wait a bit for the server to send their actual ping.

A number indicating the current rain level. When it isn't raining, this will be equal to 0. When it starts to rain, this value will increase gradually up to 1. When it stops raining, this value gradually decreases back to 0.

Each time bot.rainState is changed, the "weatherUpdate" event is emitted.

  • /regex/ - a regular expression pattern, that should have at least two capture groups
  • 'chattype' - the type of chat the pattern matches, ex "chat" or "whisper", but can be anything.

bot.oxygenLevel

Number in the range [0, 20] respresenting the number of water-icons known as oxygen level.

The total number of ticks since day 0.

This value is of type BigInt and is accurate even at very large values. (more than 2^51 - 1 ticks)

bot.time.time

The total numbers of ticks since day 0.

Because the Number limit of Javascript is at 2^51 - 1 bot.time.time becomes inaccurate higher than this limit and the use of bot.time.bigTime is recommended. Realistically though you'll probably never need to use bot.time.bigTime as it will only reach 2^51 - 1 ticks naturally after ~14280821 real years.

bot.time.timeOfDay

Time of the day, in ticks.

Time is based on ticks, where 20 ticks happen every second. There are 24000 ticks in a day, making Minecraft days exactly 20 minutes long.

The time of day is based on the timestamp modulo 24000. 0 is sunrise, 6000 is noon, 12000 is sunset, and 18000 is midnight.

bot.time.day

Day of the world.

bot.time.isDay

bot.time.bigAge

Age of the world, in ticks.

This value is of type BigInt and is accurate even at very large values. (more than 2^51 - 1 ticks)

bot.time.age

Age of the world, in ticks.

Because the Number limit of Javascript is at 2^51 - 1 bot.time.age becomes inaccurate higher than this limit and the use of bot.time.bigAge is recommended. Realistically though you'll probably never need to use bot.time.bigAge as it will only reach 2^51 - 1 ticks naturally after ~14280821 real years.

Mapping of member to team. Uses usernames for players and UUIDs for entities.

bot.controlState

An object whose keys are the main control states: ['forward', 'back', 'left', 'right', 'jump', 'sprint', 'sneak'].

Setting values for this object internally calls bot.setControlState.

  • options - Options for the search:
    • point - The start position of the search (center). Default is the bot position.
    • matching - A function that returns true if the given block is a match. Also supports this value being a block id or array of block ids.
    • useExtraInfo - To preserve backward compatibility can result in two behavior depending on the type
      • boolean - Provide your matching function more data - noticeably slower aproach
      • function - Creates two stage maching, if block passes matching function it is passed further to useExtraInfo with additional info
    • maxDistance - The furthest distance for the search, defaults to 16.
    • count - Number of blocks to find before returning the search. Default to 1. Can return less if not enough blocks are found exploring the whole area.

  • craftingTable - a Block instance. If null, only recipes that can be performed in your inventory window will be included in the list.

bot.recipesAll(itemType, metadata, craftingTable)

The same as bot.recipesFor except that it does not check wether the bot has enough materials for the recipe.

bot.nearestEntity(match = (entity) => { return true })

Return the nearest entity to the bot, matching the function (default to all entities). Return null if no entity is found.

Example:

const cow = bot.nearestEntity(entity => entity.name.toLowerCase() === 'cow') // we use .toLowercase() because in 1.8 cow was capitalized, for newer versions that can be ommitted

bot.creative.flyTo(destination, [cb])

This function also returns a Promise, with void as its argument upon completion.

Calls startFlying() and moves at a constant speed through 3d space in a straight line to the destination. destination is a Vec3, and often the x and z coordinates will end with .5. This operation will not work if there is an obstacle in the way, so it is advised to fly very short distances at a time.

When the bot arrives at the destination, cb is called.

This method does not attempt any path finding. It is expected that a path finding implementation will use this method to move < 2 blocks at a time.

To resume normal physics, call stopFlying().

bot.creative.startFlying()

Sets bot.physics.gravity to 0. To resume normal physics, call stopFlying().

This method is useful if you want to hover while digging the ground below you. It is not necessary to call this function before calling flyTo().

Note that while flying, bot.entity.velocity will not be accurate.

bot.creative.stopFlying()

Restores bot.physics.gravity to it's original value.
