Vector2

Vector2 is a structure that defines a two-dimensional point.

struct Vector2 (

T

) if (

isNumeric!(T)

) {

this(T x, T y);

this(U x, U y);

this(const Vector2!(U) vec);

Vector2!(T) opOpAssign(const Vector2!(T) vec);

Vector2!(T) opOpAssign(float num);

Vector2!(T) opBinary(const Vector2!(T) vec);

Vector2!(T) opBinary(float num);

Vector2!(T) opNeg();

bool opEquals(const Vector2!(T) vec);

bool isEmpty();

float scalar(const Vector2!(T) vec);

alias dot = scalar;

float length [@property getter];

float angle(const Vector2!(T) vec, bool degrees = true);

float diff(const Vector2!(T) vec);

Vector2!(T) normalize();

}

Constructors

this this(T x, T y): CTor

Members

Aliases

dot alias dot = scalar: alias for scalar

Functions

angle float angle(const Vector2!(T) vec, bool degrees = true): Calculate the angle between two vectors. If the second paramter is true, the return value is converted to degrees. Otherwise, radiant is used.
diff float diff(const Vector2!(T) vec): Calculate the diff between two vectors.
isEmpty bool isEmpty(): Checks if this vector is empty. This means that his coordinates are 0.
normalize Vector2!(T) normalize(): Normalize the vector in which the coordinates are divided by the length.
opBinary Vector2!(T) opBinary(const Vector2!(T) vec): Supported operation: +, -, *, / and %
opBinary Vector2!(T) opBinary(float num): Supported operation: +, -, *, / and %
opEquals bool opEquals(const Vector2!(T) vec): Compares two vectors by checking whether the coordinates are equals.
opNeg Vector2!(T) opNeg(): Returns a negated copy of this Vector.
opOpAssign Vector2!(T) opOpAssign(const Vector2!(T) vec): Supported operation: +=, -=, *=, /= and %=
opOpAssign Vector2!(T) opOpAssign(float num): Supported operation: +=, -=, *=, /= and %=
scalar float scalar(const Vector2!(T) vec): Calculate the scalar product.

Properties

length float length [@property getter]: Calculate the length.

Variables

x T x;: The x coordinate
y T y;: The y coordinate
