## 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 Variables

 one Shorthand for writing Vector4(1,1,1,1). zero Shorthand for writing Vector4(0,0,0,0).

## Variables

 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 [0], [1], [2], [3] 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 Functions

 Set Set x, y, z and w components of an existing Vector4. ToString Returns a nicely formatted string for this vector.

## Static Functions

 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 Project Projects a vector onto another vector. Scale Multiplies two vectors component-wise.

## Operators

 operator - Subtracts one vector from another. operator != Returns true if vectors different. operator * Multiplies a vector by a number. operator / Divides a vector by a number. operator + Adds two vectors. operator == Returns true if the vectors are 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.
