Corona SDK variable throughout different scenes

Question

I would like to know how to manage variables in corona throughout different scenes. In my game score variable is in every scene what i want to know is how to continuously add the score per scene, because every time the scene changes the score automatically becomes zero.

Answer 1

You can use a separate file. Example:

mydata.lua

With a table:

local M = {}
return M

-- Then in your game.lua you can simply require it:

local mydata = require( "mydata" )

and use for example a score:

mydata.score = 0

In your highscore.lua or whatever you can call it easy pzy:

local mydata = require( "mydata" )

and now you can use mydata.score saved value

Answer 2

I hope Scenes are no more used . You can try the composer which is very effective and efficient .

http://docs.coronalabs.com/api/library/composer/index.html

It has two functions setVariable() and getVariable(). Using these functions you can pass your score from one scene to other .

since using of global variable may lead to memory leak, its better not use the global variabes
