# Lua Vector (update 2)

mrsimb - Custom level - from WindowsTo use Vector in your Lua project, just copy compressed version from this this level to end of Lua script code.

Or copy it from here: http://pastebin.com/gZSvYxLQ

I would appreciate if you'll found any bugs or miscalculations.

Create new vector from given parameters

v1 = Vector(1, 2, 3)

array = {4, 5, 6}

v2 = Vector(array)

You can use skip some parameters

v1 = Vector() - [0, 0, 0]

v1 = Vector(1) - [1, 0, 0]

Create vector from given angle

Vector.fromAngle(math.pi)

Create 2D vector from random angle

Vector.random2d()

Create 3D vector from random angle

Vector.random3d()

You can use basic arithmetics operators

v3 = (v1 + v2) * 0.5

Access to vector components

v1:x or v1[1]

v1:y or v1[2]

v1:z or v1[3]

Set vector components

v1:set(0.5, 10, 2)

v1:set(array)

Create vector copy

v2 = v1:copy()

Get vector string representation

str = v1:toString()

str = tostring(v1)

Get vector array representation

array = v1:toArray()

Adds values to vector

v1:add(1, 1, 1)

v1:add(array)

Substract values from vector

v1:sub(1, 1, 1)

v1:sub(array)

Multpiply vector components

v1:mul(0.5)

Divide vector components

v1:div(3)

Raise vector components to a power

v1:pow(4)

Equality check againist another vector

v1:eq(v2)

v1:eq(array)

Vector magnitude is less than another's

v1:lt(v2)

v1:lt(array)

Vector magnitude is less or equals another's

v1:le(v2)

v1:le(array)

Get vector magnitude (length)

v1:mag()

Squared magnitude (faster)

v1:magSq()

Distance beetween vector points

v1:dist(v2)

Squared distance beetween vector points

v1:distSq(v2)

Cross product of vectors

v1:cross(v2)

Dot product of vectors

v1:dot(v2)

Normalize vector

v1:norm()

Limit magnitude of vector to max value

v1:limit(5)

Angle of rotation for vector in radians (only 2D vectors)

v1:angle()

Angle between vectors in radians

v1:angleBetween(v2)

Rotates vector by angle in radians (only 2D vectors)

v1:rotate(math.pi / 2)

Linear interpolation from one vector to another

v1:lerp(v2, 0.5)

Checks if variable is vector

Vector.isVector(v1)
