vec.lua

The simplest library to hold 2- and 3-dimensional vectors with some math operations

---

Initializing the library

local vec = require("vec")

Creating a vector

print(vec.new(12, 12))
--result: (12, 12)

Adding and subtracting vectors

local smol = vec.new(1, 2)
local BIGG = vec.new(2, 3)
print(smol + BIGG) --result: (3, 5)
print(BIGG - smol) --result: (1, 1)

Multiplying vectors with vectors and numbers

local first = vec.new(1, 2)
local second = vec.new(2, 3)
print(first * second) --result: (2, 6)
print(first * 2) --result: (2, 4)

Dividing vectors with vectors and numbers

local first = vec.new(2, 6)
local second = vec.new(1, 2)
print(first / second) --result: (2, 3)
print(first / 2) --result: (1, 3)

Testing equality

local first = vec.new(1, 2)
local second = vec.new(1, 2)
local third = vec.new(1, 3)
print(first == second) --result: true
print(first == third) --result: false
