.
- If
x
is a Number, returns a Vector of anglex
and length 1. - If

a
and b
must both be Vectors.

if the input is nullish.
Max
Max(a, b) -> value
Returns the larger of two values. If both values are Numbers, the larger Number is returned. If both values are Vectors, the longer Vector is returned. If either value is nullish, the other value is returned.
Min
Min(a, b) -> value
Returns the smaller of two values. If both values are Numbers, the smaller Number is returned. If both values are Vectors, the shorter Vector is returned. If either value is nullish, the other value is returned.
Mix
Mix(alpha, from, to) -> value
Returns a value that is a mix between from
and to
.
The mixing is done using linear interpolation.
alpha
controls the amount of blending and should be a value between 0
and 1
,
where 0
is from
and 1
is to
. Defaults to 0
if not provided.
If only one of the inputs is nullish, the other input is returned.
Pi
Pi -> number
Returns the value of PI.
Quantize
Quantize(x, quant) -> number
Returns the input x
rounded to the nearest multiple of quant
.
Both x
and quant
can be a Number or a Vector.
If the input is a Vector, quantizes both components of the Vector.
If quant
is also a Vector, quantizes each component of the input using the corresponding component of quant
.
Returns undefined
if either input is nullish.
Examples:
let output1 = Quantize(9.7, 2) // output1 is 10
let output2 = Quantize(@(9.7, 10.2), 2) // output2 is @(10, 10)
let output3 = Quantize(@(9.7, 10.2), @(2, 3)) // output3 is @(10, 9)
Random
this?.Random -> number
Returns a random floating-point number between 0
(inclusive) and 1
(exclusive).
this
(Entity): Determine's which entity's random number generator to use. If nullish, usesWorld
. This is optional and is only used to help increase stability if a network rollback occurs.
RandomVector
this?.RandomVector -> vector
Returns a Vector with a random angle and length 1.
this
(Entity): Determine's which entity's random number generator to use. If nullish, usesWorld
. This is optional and is only used to help increase stability if a network rollback occurs.
Rotate
x.Rotate(rotate) -> vector
Returns a vector rotated by rotate
radians.
If rotate
is nullish, the input is returned unchanged.
Returns undefined
if the input is nullish.
RotateLeft
RotateLeft(x) -> vector

Returns undefined
if the input is nullish.
RotateRight
RotateRight(x) -> vector

Returns undefined
if the input is nullish.
Round
Round(x) -> number
Returns the integer nearest to the number.
If the value is halfway between two integers, rounds away from zero.
Returns undefined
if the input is nullish.
Sign
Sign(x) -> number
Returns the sign of a number.
- If the number is positive, returns
1
. - If the number is negative, returns
-1
. - If the number is
0
, returns0
.
Returns undefined
if the input is nullish.
SignedRandom
this?.SignedRandom -> number
Returns a random floating-point number between -1
(inclusive) and 1
(inclusive).
this
(Entity): Determine's which entity's random number generator to use. If nullish, usesWorld
. This is optional and is only used to help increase stability if a network rollback occurs.

Towards
a.Towards(b, limit) -> vector
Returns a Vector or Number that moves from a
towards b
by a maximum step of limit
.
In other words, if the distance between a
and b
is less than limit
, returns b
,
otherwise returns a point or value limit
distance away from a
in the direction towards b
.
If both a
and b
are Numbers, performs the calculation in 1-dimension, returning a Number.
If both a
and b
are Vectors, performs the calculation in 2-dimensions, returning a Vector.
If a
is nullish, returns undefined
.
If b
or limit
is nullish, returns a
.

Truncates a Vector or Number to a maximum length.
If x
is a Vector, returns a Vector with a length of at most limit
, but in the same direction.
If x
is a Number, returns a Number with an absolute value of at most limit
, but with the same sign.
If limit
is nullish, returns x
unchanged.
If x
is nullish, returns undefined
.
