Properties

final Type runtimeType #

inherited from Object

A representation of the runtime type of the object.

external Type get runtimeType;

int x #

int x;

int y #

int y;

int z #

int z;

Operators

bool operator ==(other) #

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.

docs inherited from Object
bool operator ==(final other) {
  return other is Color3 && x == other.x && y == other.y && z == other.z;
}

Methods

new Color3() #

Color3() : x = 0, y = 0, z = 0;

new Color3.fromColor3(Color3 color) #

Color3.fromColor3(Color3 color)
    : x = color.x, y = color.y, z = color.z;

new Color3.fromRGB(int r, int g, int b) #

Color3.fromRGB(int r, int g, int b) : x = r, y = g, z = b;

new Color3.fromRGBF(double r, double g, double b) #

Color3.fromRGBF(double r, double g, double b)
    : x = (r * 255).floor().toInt(),
      y = (g * 255).floor().toInt(),
      z = (b * 255).floor().toInt();

int hashCode() #

inherited from Object

Get a hash code for this object.

All objects have hash codes. Hash codes are guaranteed to be the same for objects that are equal when compared using the equality operator ==. Other than that there are no guarantees about the hash codes. They will not be consistent between runs and there are no distribution guarantees.

If a subclass overrides hashCode it should override the equality operator as well to maintain consistency.

external int hashCode();

noSuchMethod(String name, List args) #

inherited from Object

noSuchMethod is invoked when users invoke a non-existant method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod. If noSuchMethod returns a value, that value becomes the result of the original invocation.

The default behavior of noSuchMethod is to throw a noSuchMethodError.

external Dynamic noSuchMethod(String name, List args);

const Object() #

inherited from Object

Creates a new Object instance.

Object instances have no meaningful state, and are only useful through their identity. An Object instance is equal to itself only.

const Object();

void setFromColor3(Color3 color) #

void setFromColor3(Color3 color) {
  x = color.x;
  y = color.y;
  z = color.z;
}

void setFromRGB(int r, int g, int b) #

void setFromRGB(int r, int g, int b) {
  x = r; y = g; z = b;
}

void setFromRGBF(double r, double g, double b) #

void setFromRGBF(double r, double g, double b) {
  x = (r * 255).floor().toInt();
  y = (g * 255).floor().toInt();
  z = (b * 255).floor().toInt();
}

String toString() #

inherited from Object

Returns a string representation of this object.

external String toString();
