Vector2d ()
Creates a new instance of Vector2d with the X and Y components initialized to 0.

Vector2d (x, y)
Creates a new instance of Vector2d.

x: number
Initial value of the X component of the Vector2d.

y: number
Initial value of the Y component of the Vector2d.

Reflect()
Returns a Vector2d that's reflected over the normal.

ProjectOnto()
Returns a Vector2d that represents the current Vector2d projected onto the provided Vector2d.

RotateAround()
Returns a Vector2d that represents the current Vector2d rotated around the provided point and angle.

Apply()
Executes the action with the X and Y components of this Vector2d and sets the X and Y components to the corresponding return values.

Trigger()
Executes the action with the X and Y components of this Vector2d.

Normalized()
Returns the current vector as a unit vector. The result is a vector one unit in length pointing in the same direction as the original vector.

Magnitude()
Calculates the magnitude or length of the vector

Length()
Calculates the length or magnitude of the vector

Dot()
Calculates dot product.

Abs()
Returns a Vector2d that has the current Vector2d's X and Y components as positive values.

Sign()
Returns a Vector2d that has its X and Y components converted to -1, 0 or 1 depending on the current Vector2d's component values.

Unit()
Returns the unit vector of the current vector.

Distance()
Calculates the distance between the current vector and the provided one.

Add()
Returns a Vector2d that is the result of adding the X and Y of this Vector2d to the X and Y of the provided Vector2d.

Multiply()
Returns a Vector2d that is the result of multiplying the X and Y of this Vector2d by the X and Y of the provided Vector2d.

Subtract()
Returns a Vector2d that is the result of subtracting the X and Y of this Vector2d by the X and Y of the provided Vector2d.

SubtractFrom()
Returns a Vector2d that is the result of subtracting the X and Y of this Vector2d from the X and Y of the provided Vector2d.

Divide()
Returns a Vector2d that is the result of dividing the X and Y of this Vector2d by the X and Y of the provided Vector2d.

DivideFrom()
Returns a Vector2d that is the result of dividing the X and Y of this Vector2d from the X and Y of the provided Vector2d.

IsZero()
Determines whether this Vector2d's X and Y components are zero.

Negate()
Returns a Vector2d that is the negated version of this Vector2d.

Equivalent()
Determines whether this Vector2d has the same X and Y of the provided Vector2d.

Clone()
Returns a Vector2d that has an identical X and Y component as the current Vector2d.

toString()
Overridden toString method to display Vector2d in the (X, Y) format.
