Classes and calling parent methods

seppsepp

Hi.

Following, simple scenario. I've written a class deriving from Sprite meaning to be a base class for different progress bars. Then another class inherits ProgressBar. Weird thing: Even when MegaProgressBar has its own draw() method then the parents draw() gets called too - before the MegaProgressBar:draw()? Seems to be a bug don't you think? This behaviour makes it impossible to override methods =| .


Greetings

Oh, just noticed that the behaviour is only the case when draw() gets called from within init(). Hm, probably I should move that call somewhere else...

postInit() might be what you are looking for (sorry no time to provide links!) lot of infos on the forums.

Made this test and it works as expected:

Test = Core.class(Sprite)   function Test:test() print("from Test") end   SubTest = Core.class(Test)   function SubTest:init() self:test() end   function SubTest:test() print("from SubTest") end   SubTest.new()

prints from SubTest

So the problem is somewhere else

@seppsepp and from SubTest in @ar2rsawseen post above, if you want to call parent method, you can use

function SubTest:test() print("from SubTest") Test.test(self) end

(use parent class name and . symbol and self, not : symbol)
