Constructors

Rng(int seed)

Properties

hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.

Methods

countFromFloat(double range) → int: Gets a random integer count within the given floating point range.
float([double? minOrMax, double? max]) → double: Gets a random floating-point value within the given range.
inclusive(int minOrMax, [int? max]) → int: Gets a random int within a given range. If max is given, then it is in the range [minOrMax, max]. Otherwise, it is [0, minOrMax]. In other words, inclusive(2) returns a 0, 1, or 2, and inclusive(2, 4) returns 2, 3, or 4.
item<T>(List<T> items) → T: Gets a random item from the given list.
normal() → double: Calculate a random number with a normal distribution.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
oneIn(int chance) → bool: Returns true if a random int chosen between 1 and chance was 1.
percent(int chance) → bool: Returns true chance percent of the time.
range(int minOrMax, [int? max]) → int: Gets a random int within a given range. If max is given, then it is in the range [minOrMax, max). Otherwise, it is [0, minOrMax). In other words, range(3) returns a 0, 1, or 2, and range(2, 5) returns 2, 3, or 4.
round(double value) → int: Rounds value to a nearby integer, randomly rounding up or down based on the fractional value.
setSeed(int seed) → void: Resets the random number generator's internal state to seed.
shuffle<T>(List<T> items) → void: Randomly re-orders elements in items.
take<T>(List<T> items) → T: Removes a random item from the given list.
takeOrdered<T>(List<T> items) → T: Removes a random item from the given list, preserving the order of the remaining items.
taper(int start, int chanceOfIncrement) → int
toString() → String: A string representation of this object.
inherited
triangleInt(int center, int range) → int: Gets a random number centered around center with range (inclusive) using a triangular distribution. For example triangleInt(8, 4) will return values between 4 and 12 (inclusive) with greater distribution towards 8.
vecInRect(Rect rect) → Vec: Gets a random Vec within the given Rect (half-inclusive).

Operators

operator ==(Object other) → bool: The equality operator.
