Delay in getParent()

jimlev

Hello !
Here is another question, probably a stupid one for confirmed dev but...

here is an example :

Player = Core.class(Sprite)   function Player:init(name) self.myName = name   self.myBag = Inventory.new() self:addChild(self.myBag) end     Inventory = Core.class(Sprite)   function Inventory:init(name) self.items = {}   --print(self:getParent().myName) -- give error 'attempt to index a nil value' Timer.delayedCall(1000, function() print(self:getParent().myName) end) -- output 'John' end     local firstPlayer = Player.new("John") stage:addChild(firstPlayer)

I have an error in the init of the inventory class, if I try to access the parent of my player. If I delay the demand, it works.
Anything to learn here ? Did I do something the wrong way ?
thx !

It's simple

self.myBag = Inventory.new() --executes Inventory:init method --and only after that you add it to Player as child self:addChild(self.myBag)

I usually do somekind of generate or prepare methods, for this purpose, as:

function Inventory:prepare() print(self:getParent().myName) end   function Player:init(name) self.myName = name   self.myBag = Inventory.new() self:addChild(self.myBag) self.myBag:prepare() end

of course ! it's so evident ! I'm really surprised not to have encountered this problem before...
for the 4547 times, thx a lot ar2rsawseen ! (I'm not really sure if there is more of my code or of yours in my game...)
