Tables And Metatables

[xFade]

Code: Select all

local gs = {}
gs.__index = gs

local i = ""

function gs:Init(x)
  i = x
  print(x.." Initialized!")
end

setmetatable(gs, {
    _call = function(cls,...)
      return cls.new(...)
    end,
})

function gs.NewGif(init)
  local self = setmetatable({},gs)
  local frames = love.filesystem.getDirectoryItems(init)
  print("Loading Frames From..."..init)
  for i = 1, #frames do
   -- Help Here!
  end
  return self
end

return gs

Okay so I'm not very familiar with tables/meta-tables in lua, but I do know a thing or two. What I'm trying to accomplish is to create a new image and store it in a table. And to be able to access it to draw it later on. Help is much appreciated and needed.

You should start by telling us what you're trying to accomplish, and what you can't work out/get to work.

You don't need metatables to store graphics, just load them in a regular table and access them by the index number.

Yes but how do I do it without having to write it out. In a form of a loop. How can I store all the images in the table with a loop? Like so...

Code: Select all

local frames = love.filesystem.getDirectoryItems(init)
  print("Loading Frames From..."..init)
  for i = 1, #frames do
    print("Frame: "..i.." "..frames[i])
    -- Store Image in table :/
  end

Something like this:

Code: Select all

local images = {}
local frames = love.filesystem.getDirectoryItems(init)
  print("Loading Frames From..."..init)
  for i = 1, #frames do
    print("Frame: "..i.." "..frames[i])
    -- Store Image in table
    images[i] = love.graphics.newImage(frames[i])
  end

Probably not entirely complete though, you'll need to remove directories from the frames table first. And then assuming all the other files are indeed image files.
