Vector3 Struct

Representation of 3D vectors and points.

This structure is used throughout Unity to pass 3D positions and directions around. It also contains functions for doing common vector operations.

Besides the functions listed below, other classes can be used to manipulate vectors and points as well. For example the Quaternion and the Matrix4x4 classes are useful for rotating or transforming vectors and points.

Variables

x	X component of the vector.
y	Y component of the vector.
z	Z component of the vector.
this [int index]	Access the x, y, z components using [0], [1], [2] 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

Vector3

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

Functions

Set	Set x, y and z components of an existing Vector3.
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 `Vector3(0, 0, 0)`
one	Shorthand for writing `Vector3(1, 1, 1)`
forward	Shorthand for writing `Vector3(0, 0, 1)`
up	Shorthand for writing `Vector3(0, 1, 0)`
right	Shorthand for writing `Vector3(1, 0, 0)`

Class Functions

Lerp	Linearly interpolates between two vectors.
Slerp	Spherically interpolates between two vectors.
OrthoNormalize	Makes vectors normalized and orthogonal to each other.
MoveTowards	Moves a point current towards target.
RotateTowards	Rotates a vector current towards target.
SmoothDamp	Gradually changes a vector towards a desired goal over time.
Scale	Multiplies two vectors component-wise.
Cross	Cross Product of two vectors.
Reflect	Reflects the vector along the normal.
Dot	Dot Product of two vectors.
Project	Projects a vector onto another vector.
Angle	Returns the angle in degrees between from and to.
Distance	Returns the distance between a and b.
ClampMagnitude	Returns a copy of vector with its magnitude clamped to maxLength.
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.
