Vec2

A two dimensional vector.

Properties

• x - double

• y - double

Methods

• constructor

• length

• distanceTo

• angleTo

• normalized

• scale

Vec2:new(x, y)

• x - What to set x to

• y - What to set y to

Constructs a new Vec2 with the provided x and y.

Example:

local screenPosition = Vec2:new(200, 200)

length()

Returns the length of the Vec2

Example:

local vec = Vec2:new(200, 200)
print("The vector has a length of " .. vecL:length())

distanceTo(otherVec2)

• otherVec2 - A different Vec2

Returns the distance from this vector to the otherVec2

Example:

local vecA = Vec2:new(200, 200)
local vecB = Vec2:new(400, 690)
print("Distance from vecA to vecB: " .. vecA:distanceTo(vecB))

angleTo(otherVec2)

• otherVec2 - A different Vec2

Returns the angle to the otherVec2

Example:

local vecA = Vec2:new(1, 0)
local vecB = Vec2:new(0, 1)
print("Angle between vecA and vecB: " .. vecA:angleTo(vecB)) --prints 90

normalized()

Returns this vector but normalized (that is with length 1)

Example:

local vecA = Vec2:new(20, 10)
print("vecA normalized: " .. vecA:normalized():toString()) --prints (0.8944, 0.4472)

scale(scalar)

• scalar - By how much you want to scale the vector

Returns a scaled version of this vector

Example:

local vecA = Vec2:new(20, 10)
print("vecA scaled by 2: " .. vecA:scale(2):toString()) --prints (40, 20)

toString()

Returns a string representation of the Vec2

Example:

local vecA = Vec2:new(20, 10)
print("vecA: " .. vecA:toString()) --prints (20, 10)
