Examples
Load map from image
(Note that this example creates a lot of tables.)
local filename = "image.png"
local imageData = love.image.newImageData(filename)
local width, height = imageData:getDimensions()
local map = {}
for y = 1, height do
map[y] = {}
for x = 1, width do
local r, g, b, a = imageData:getPixel(x-1, y-1)
map[y][x] = {r, g, b, a}
end
end
