9.1.1. Built-in Namespaces

9.1.2. system

The system namespace handles all types of miscellaneous behaviour typically found in the system, such as time.

Variables

The system namespace contains no variables.

Functions

Table 9.1: Supported Functions for the system namespace

Long currentTimeMillis()	Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds.
Double[] getTPS()	Returns a list of size 3, containing the average TPS over the last 1 minute, 5 minutes and 15 minutes.

9.1.3. math

The math namespace contains a series of common math operations.

Variables

The math namespace contains no variables.

Functions

Table 9.2: Supported Functions for the math namespace

Double sqrt(Double value)	Returns the correctly rounded positive square root of a double
Double abs(Double value)	Returns the absolute value of a double value. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned.
Double pow(Double value, Double exponent)	Returns the value of the first argument raised to the power of the second argument.
Int randomInt()	Returns the next pseudorandom, uniformly distributed Int value.
Long randomLong()	Returns the next pseudorandom, uniformly distributed Long value.
Float randomFloat()	Returns the next pseudorandom, uniformly distributed float value between 0.0 and 1.0.
Double randomDouble()	Returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0.
Double random(Double min, Double max)	Returns the next pseudorandom, uniformly distributed double value between min and max.
Double sin(Double x)	Returns the sin of a double (takes degrees).
Double cos(Double x)	Returns the cos of a double (takes degrees).
Double tan(Double x)	Returns the tan of a double (takes degrees).
Double arcsin(Double x)	Returns the arcsin of a double (takes degrees).
Double arccos(Double x)	Returns the arccos of a double (takes degrees).
Double arctan(Double x)	Returns the arctan of a double (takes degrees).
Double radsin(Double x)	Returns the sin of a double (takes radians).
Double radcos(Double x)	Returns the cos of a double (takes radians).
Double radtan(Double x)	Returns the tan of a double (takes radians).
Double radarcsin(Double x)	Returns the arcsin of a double (takes radians).
Double radarccos(Double x)	Returns the arccos of a double (takes radians).
Double radarctan(Double x)	Returns the arctan of a double (takes radians).
Double rad(Double x)	Returns the double converted to radians (takes degrees).
Double deg(Double x)	Returns the double converted to degrees (takes radians).

Most of these functions have special cases with special arguments. View https://docs.oracle.com/javase/10/docs/api/java/lang/Math.html for these cases.

9.1.4. util

Variables

The util namespace contains no variables.

Functions

Supported Functions for the util namespace

Boolean executeAndQuerySuccess(String command)	Run an /execute Minecraft command and get the success value.
Int executeAndQueryResult(String command)	Run an /execute Minecraft command and get the result value.
String randomUUID()	Randomly generates a UUID.

9.1.5. format

Variables

The format namespace contains no variables.

Functions

Supported Functions for the format namespace

formatDate(Long unixDateMillis, String format)	Returns the converted unix date in the format specified by format.

9.1.6. timer

Variables

The timer namespace contains no variables.

Functions

Never store a Timer instance in a namespace variable. It will break on you silently. ALWAYS use timer::getCustomTimer().

Supported Functions for the timer namespace

getMapTimer(Player player, String mapcode)	Get a player’s timer for a map.
getChallengeTimer(Player player, String challengecode)	Get a player’s timer for a challenge.
getCustomTimer(Player player, String tag)	Gets a player’s custom timer. You can construct custom timers by instantiating the timer::Timer type.
getSpecialTimer(Player player, String tag)
removeCustomTimer(Player player, String tag)	Removes a custom timer.
String formatTime(Long time).	Format a time into a string.
