A '''vector''' is a data structure that holds 2, 3, or 4 numbers. It is commonly used to refer to positions and rotations of things. 

== Swizzling ==
Swizzling refers to changing components of vectors by re-arranging the values already present.

To perform a swizzling operation, index the vector with between 2 and 4 <code>x</code>, <code>y</code>, <code>z</code>, <code>w</code>, or <code>_</code> characters.
A new vector will be formed from the components specified (i.e. <code>v.xxxx</code> will create a new vector from the <code>x</code> component of <code>v</code> repeated 4 times.) The <code>_</code> component will fill in a value of 0 in any position where it is specified.

For example, if <code>v</code> is a {{type|Vector4}}, the following are all valid and return a new Vector4:

* <code>v.xyzw</code>
* <code>v.xxzz</code>
* <code>v.wzyx</code>
* <code>v.wyxy</code>
* <code>v.___x</code>

Swizzling operations can also transform vectors between sizes.
For example, to create a {{type|Vector2}} from a {{type|Vector3}}'s x and y components, use <code>v3.xy</code>.
This works in both directions – a common action is upgrading a Vector2 to a Vector3 by adding a 0 as the Z component:

<syntaxhighlight lang="lua" highlight="3">
local vec2 = vec(1, 2)
print(vec2) -- {1, 2}
local vec3 = vec2.xy_ -- or .x_y, ._xy, ...
print(vec3) -- {1, 2, 0}
</syntaxhighlight>
