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.
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). |
Vector3 |
Creates a new vector with given x, y, z components. |
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. |
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) |
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. |
