Saving and lodaing flash game

[overlordlink]

Ok well.... my idea here is to have a save button that saves you data, or an auto save function either one. Then when you start your game, have a load button that loads the data and takes you to the corresponding level.

For the save button code I have this.


on(release){
savefile.data.levelnum= _root.levelnum;
savefile.flush();
}


And the load button code is.



on(release){
var savefile = SharedObject.getLocal("test");
_root.levelnum = savefile.data.levelnum;
}
if (savefile.data.levelnum == undefined ){
_root.gotoAndStop("level1")


Now the only problem with this is I don't know how to actually implement it. For instance it saving the levelnum equal to 4 then when it loads having it go to the fourth level.

Use a switch/case statement. http://www.tech-recipes.com/rx/2369/as3_switch_case_statement_syntax/

well that doesn't really help that as3 and I am using as2.

Here is how a switch works in as3:



var someVariable:String = "something";

switch(someVariable)
{
case "something" :
trace("it's something");
break;
case "somethign else" :
trace("it's something else");
break;
default :
trace("dunno!");
break;
}


Here is how a switch works in as2:



var someVariable:String = "something";

switch(someVariable)
{
case "something" :
trace("it's something");
break;
case "somethign else" :
trace("it's something else");
break;
default :
trace("dunno!");
break;
}

So if I have this right it would go like this?




var savefile = SharedObject.getLocal("test");

switch(savefile)
{
case "_root.levelnum = 1" :
trace("level1");
break;
case "_root.levelnum = 2" :
trace("level2");
break;
default :
trace("level1");
break;
}

the switch lets you compare many variables, not just strings.



var someVariable:String = 1234;

switch(someVariable)
{
case 2 :
trace("the number is 2!");
break;
case 1234 :
trace("the number is 1234!");
break;
default :
trace("dunno!");
break;
}


you'd probably be storing the level to load so you could do something like this:



var levelToLoad = 1;

switch(levelToLoad)
{
case 1 :
trace("load level 1!");
break;
case 2 :
trace("load level 2!");
break;
default :
trace("don't know which level to load!");
break;
}
