First, I don’t see a call to string.gsub(), so that must be happening elsewhere, nonetheless we can move forward.
Second, You’re not using composer correctly. You didn’t insert any of your object into the scene group so the scene won’t manage them.
I’ve re-written and formatted your code a bit (to the best of my ability based on what I see):
-
Create a new file call ext.lua:
local json = require( “json” ) – == – table.save( theTable, fileName [, base] ) - Saves table to file (Uses JSON library as intermediary) – == function table.save( theTable, fileName, base ) local base = base or system.DocumentsDirectory local path = system.pathForFile( fileName, base ) local fh = io.open( path, “w” ) local tmpTable = table.deepStripCopy(theTable) if(fh) then fh:write(json.encode( tmpTable )) io.close( fh ) return true end return false end – == – table.load( fileName [, base] ) - Loads table from file (Uses JSON library as intermediary) – == function table.load( fileName, base ) local base = base or system.DocumentsDirectory local path = system.pathForFile( fileName, base ) local fh, reason = io.open( path, “r” ) if fh then local contents = fh:read( “*a” ) io.close( fh ) local newTable = json.decode( contents ) return newTable else return nil end end
-
Replace main.lua with this:
display.setStatusBar(display.HiddenStatusBar); local composer = require “composer” local loadsave = require(“loadsave”) require “ext” – Load my table save/load functions _W = display.contentWidth; _H = display.contentHeight; centerX = display.contentCenterX centerY = display.contentCenterY _G.myGameSettings = table.load( “myGameSettings.json” ) if( not myGameSettings ) then myGameSettings = {} myGameSettings.highScoreWorld1 = 0 myGameSettings.highScoreWorld2 = 0 myGameSettings.plane2 = “plane2L.png” myGameSettings.terrain2 = “terrain2L.png” myGameSettings.terrain3 = “terrain3L.png” table.save( myGameSettings, “myGameSettings.json” ) end – Load the composer scene composer.gotoScene( “menu1” )
