method 'changeScene' (a nil value) [Problem]

ozergul

Hi
I am getting this error.

main.lua:20: attempt to call method 'changeScene' (a nil value)

This are my main.lua codes:

SceneManager = gideros.class(Sprite)   sceneManager = SceneManager.new({ ["mainmenu"] = mainmenu })   stage:addChild(sceneManager)     -- show main menu sceneManager:changeScene("mainmenu", 1, SceneManager.moveFromRight, easing.outBack)     -- main menu sceene init mainmenu = gideros.class(Sprite) function mainmenu:init() local a = Bitmap.new(Texture.new("ball.png", true)) self:addChild(a) end

Also I am includeing scenemanager.lua, easing.lua and gtween.lua

What is the problem..

Hi @ozergul I think that your problem is

SceneManager = gideros.class(Sprite)

because it's overwriting the "real" SceneManager (contained in scenemanager.lua) with a Sprite (core class) which doesn't have changeScene method. (just remove it, unless I didn't notice something else it should work).

Also, you should not use gideros.class to create objects, but Core.class(Sprite) ie. to create a Sprite - it should work anyway but the current syntax uses Core.class()

Yep, remove the first line of code.
