Vector

vec is a global constructor for 3D vectors. Creates a {x, y, z} table with the vector metatable. All methods that accept vectors will accept {x, y, z}, {x=x, y=y, z=z} and vec(x, y, z)

local v = vec(1, 2, 3)

Metatable name: "vec"

Properties

Three read/write numeric properties: v.x, v.y, v.z. They can also be accessed via index (v["x"], v[1]).

Operators

Operator	Example	Behaviour
+	v1 + v2	Component-wise addition
-	v1 - v2	Component-wise subtraction
*	v1 * v2	Component-wise multiplication
*	v * n or n * v	Scalar multiplication
/	v / n	Scalar division
-	-v	Negation
==	v1 == v2	Equality (all components equal)
tostring	tostring(v)	Returns "(x, y, z)"

local a = vec(1, 2, 3)
local b = vec(4, 5, 6)

local sum     = a + b         -- Vec(5, 7, 9)
local diff    = a - b         -- Vec(-3, -3, -3)
local compMul = a * b         -- Vec(4, 10, 18)
local scalar  = a * 10        -- Vec(10, 20, 30)
local div     = a / 2         -- Vec(0.5, 1, 1.5)
local neg     = -a            -- Vec(-1, -2, -3)
print(tostring(a))            -- "(1, 2, 3)"
