Class: (global)
Description
Support to Luau vectors.
(table) = vector(c1,c2[,c3])
Parameters
c1: (number) first vector coordinate
c2: (number) second vector coordinate
c3: (number) third vector coordinate optional
Return values
Returns (table) the vector coordinates, or nan if not a number
Examples
Adding two vectors
local v1 = vector(1, 3, 5)
local v2 = vector(2, 4, 6)
print(v1 + v2) -- 3, 7, 11, nan
Setting a sprite position
local pix = Pixel.new(0x0000ff, 1, 32, 32)
local pixpos = vector(32, 64)
pix:setPosition(pixpos.x, pixpos.y)
