## Description

Representation of four-dimensional vectors.

This structure is used in some places to represent four component vectors (e.g. mesh tangents, parameters for shaders). In the majority of other cases a Vector3 is used.

## Static Properties

 negativeInfinity Shorthand for writing Vector4(float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity). one Shorthand for writing Vector4(1,1,1,1). positiveInfinity Shorthand for writing Vector4(float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity). zero Shorthand for writing Vector4(0,0,0,0).

## Properties

 magnitude Returns the length of this vector (Read Only). normalized Returns this vector with a magnitude of 1 (Read Only). sqrMagnitude Returns the squared length of this vector (Read Only). this[int] Access the x, y, z, w components using , , ,  respectively. w W component of the vector. x X component of the vector. y Y component of the vector. z Z component of the vector.

## Constructors

 Vector4 Creates a new vector with given x, y, z, w components.

## Public Methods

 Equals Returns true if the given vector is exactly equal to this vector. Set Set x, y, z and w components of an existing Vector4. ToString Return the Vector4 formatted as a string.

## Static Methods

 Distance Returns the distance between a and b. Dot Dot Product of two vectors. Lerp Linearly interpolates between two vectors. LerpUnclamped Linearly interpolates between two vectors. Max Returns a vector that is made from the largest components of two vectors. Min Returns a vector that is made from the smallest components of two vectors. MoveTowards Moves a point current towards target. Normalize Makes this vector have a magnitude of 1. Project Projects a vector onto another vector. Scale Multiplies two vectors component-wise.

## Operators

 operator - Subtracts one vector from another. operator * Multiplies a vector by a number. operator / Divides a vector by a number. operator + Adds two vectors. operator == Returns true if two vectors are approximately equal. Vector2 Converts a Vector4 to a Vector2. Vector3 Converts a Vector4 to a Vector3. Vector4 Converts a Vector3 to a Vector4. Vector4 Converts a Vector2 to a Vector4.
