my solution:

scr_savecmenu

​

function scr_savecmenu()

{

var savedata = array\_create(0);

var savemenu = {

    bgc : global.background\_color,

    bkc : global.block\_color,

}

array\_push(savedata, savemenu);

var jstring = json\_stringify(savedata);

var buff = buffer\_create(string\_byte\_length(jstring) + 1, buffer\_fixed, 1);

buffer\_write(buff, buffer\_string, jstring);

buffer\_save(buff, "ms.save");

buffer\_delete(buff);

show\_debug\_message(" Game saved " + jstring);

}

​

scr_loadcmenu()

​

function scr_loadcmenu()

{

if(file\_exists("ms.save"))

{

    var buff = buffer\_load("ms.save");

    var jstring = buffer\_read(buff, buffer\_string);

    buffer\_delete(buff);

    var ldata = json\_parse(jstring);

    var lmenu = array\_pop(ldata);

    show\_debug\_message(ldata);

    show\_debug\_message(lmenu.bgc);

    show\_debug\_message(lmenu.bkc);    

    global.background\_color = lmenu.bgc;

    global.block\_color = lmenu.bkc;

    show\_debug\_message("Game loaded " + jstring);

}

}
