Vector3

Description

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.

Static Variables

backShorthand for writing Vector3(0, 0, -1).
downShorthand for writing Vector3(0, -1, 0).
forwardShorthand for writing Vector3(0, 0, 1).
leftShorthand for writing Vector3(-1, 0, 0).
oneShorthand for writing Vector3(1, 1, 1).
rightShorthand for writing Vector3(1, 0, 0).
upShorthand for writing Vector3(0, 1, 0).
zeroShorthand for writing Vector3(0, 0, 0).

Variables

magnitudeReturns the length of this vector (Read Only).
normalizedReturns this vector with a magnitude of 1 (Read Only).
sqrMagnitudeReturns the squared length of this vector (Read Only).
this[int]Access the x, y, z components using [0], [1], [2] respectively.
xX component of the vector.
yY component of the vector.
zZ component of the vector.

Constructors
