Vector4 Struct

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.

Variables

x	X component of the vector.
y	Y component of the vector.
z	Z component of the vector.
w	W component of the vector.
this [int index]	Access the x, y, z, w components using [0], [1], [2], [3] respectively.
normalized	Returns this vector with a magnitude of 1 (Read Only).
magnitude	Returns the length of this vector (Read Only).
sqrMagnitude	Returns the squared length of this vector (Read Only).

Constructors

Vector4

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

Functions

Set	Set x, y, z and w components of an existing Vector4.
Scale	Multiplies every component of this vector by the same component of scale.
Normalize	Makes this vector have a magnitude of 1.
ToString	Returns a nicely formatted string for this vector.

Class Variables

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

Class Functions

Lerp	Linearly interpolates between two vectors.
MoveTowards	Moves a point current towards target.
Scale	Multiplies two vectors component-wise.
Dot	Dot Product of two vectors.
Project	Projects a vector onto another vector.
Distance	Returns the distance between a and b.
Min	Returns a vector that is made from the smallest components of two vectors.
Max	Returns a vector that is made from the largest components of two vectors.
operator +	Adds two vectors.
operator -	Subtracts one vector from another.
operator *	Multiplies a vector by a number.
operator /	Divides a vector by a number.
operator ==	Returns true if the vectors are equal.
operator !=	Returns true if vectors different.
operator Vector4	Converts a Vector3 to a Vector4.
operator Vector3	Converts a Vector4 to a Vector3.
operator Vector4	Converts a Vector2 to a Vector4.
operator Vector2	Converts a Vector4 to a Vector2.
