I think it would be good to point out that you are using the SECS library to create your classes. Always try to give info like that. Also, providing the .love file directly helps people play with it and get at it quicker.

Anyway, from the recent code and playing with it, I see two things wrong that I think changing should fix it up.

1. Remove "badie = {}" from badie.lua. By having that there, you are erasing "badie = class:new()" by telling badie to be something else.
2. "b = badie:init(someX, someY)" is setting b to nil. Make it not be nil and it won't be nil.

Now, you may be lost on how you're setting it to nil. Remember that when you do "x = someFunction()", you are telling x to be what value someFunction gives to it. Your init function is not giving b anything, and nothing is nil in Lua.

What you want to do is give the badie setup to b.

Code: Select all

function badie:init( x, y)
   self.x = x
   self.y = y
   self.dx = 1
   self.dy = 1
   self.alive = true

   return self -- this should do the trick
end

edit: Oh, the code has changed since I downloaded it....

try a new function called badie:new()

Code: Select all

function baddie:new(x, y)
    local newBad = {}
    setmetatable(newBad, self)
    self.__index = self
    self:init(x, y)
    return newBad
end

Then call it as b = baddie:new(math.random(whatever), math.random(whatever))
This will make a new entity that is unique and properly linked to your class. I hope this helps and happy coding

baddie.__index = baddie
function baddie.new(x, y) -- ":"-syntax makes it harder to distinguish between "class" and "object" methods 
    local newBad = {}
    setmetatable(newBad, baddie)
    newBaddie:init(x, y) -- this was an actual error in your code
    return newBad
end
