TGB Platformer Kit Save and Load System in 1 File

But without any further ado, let's implement this code. This script will save the file in to a script *.cs file using the function "writeFile()" and "readFile()". It is important that you do not tamper with the variables. All you need to do is follow these steps:

1. Make a file called "WriteLoadSave.cs" in the gameScripts folder.

2. In that, you need to paste the following code:

function writeFile()
{
%file = new FileObject();

if(%file.openForWrite("~/data/saves/savedgame.cs"))
{

//Now for the actual saving!

%file.writeLine("$SaveDir = " @ $SaveDir);
%file.writeLine("sceneWindow2D.loadLevel( expandFilename($SaveDir) ); ");
good();

playSound( "LevelSaved", 1.5 );

echo("sucess!");
}
else
{
error("File is not open for saving!");
bad();
}

%file.close();
%file.delete();
}

//////////////////////////////////////////////////////////////////////////////////////////

function readFile()
{
%file = new FileObject();

good();

if(%file.openForRead("~/data/saves/savedgame.cs"))
{
%x=1;
while(!%file.isEof())
{
$playerlevel = %file.readLine();
exec ("~/data/saves/savedgame.cs");
%x++;

}
}
else
{
error("CANNOT OPEN FOR READ");
bad();
}


%file.close();
%file.delete();
}

//Save Directory: This will stell the variable "$SaveDir" what the level's names are. Just call one of the functions, then writelfile and readfile.

function tutorial()
{
$SaveDir = "\"game/data/levels/demoLevel.t2d\";";
}

function level1()
{
$SaveDir = "\"game/data/levels/Level1.t2d\";";
}

function level2()
{
$SaveDir = "\"game/data/levels/Level2.t2d\";";
}

function level3()
{
$SaveDir = "\"game/data/levels/Level3.t2d\";";
}

function level4()
{
$SaveDir = "\"game/data/levels/Level4.t2d\";";
}

function level5()
{
$SaveDir = "\"game/data/levels/Level5.t2d\";";
}

function level6()
{
$SaveDir = "\"game/data/levels/Level6.t2d\";";
}

//Add any other levels to the directory. They should correspond with the function name. Just copy one of the examples and name the file. Example: (Notice that the //'s disable the function. Do not copy those.)
//Be careful not to edit the "'s. It took a long time to place those!!!

//function level12()
//{
//$SaveDir = "\"game/data/levels/Level12.t2d\";";
//}

Now that wasn't so hard, was it? Well… there is more. You need to execute the files for this to work, but it's still one save code in one file because the executing part isn't save-related. :P

Add this to "games.cs" in the gameScripts folder in the function "startGame(%level);"

exec ( "./WriteLoadSave.cs" );

And… that's it! To use the function first start the game. Then write in the console "level1()" or "tutorial." Then put "writeFile()" and then "readFile." It should load the level, provided it's file name is "level1.t2d." Otherwise, you have to adapt the script likewise.

Enjoy data-loss-free gaming!

(12/18/12)UPDATE 2:

I thought you might want to see my current save code to get an idea of what you can do with this thing:

//Put this little save thing here...

TheoraVideo.setFile("game/data/video/menuvideo.ogg");

function writeFile()
{  
%file = new FileObject();
  
if(%file.openForWrite("~/data/saves/savedgame" @ "-" @ $SaveExt @ ".cs"))
{  
//Lets gather a few variables to save, shall we?
//Now for the actual saving!

echo($Pref::points);
echo($Game::Player.Position);
echo($Game::Player.Lives);
echo($Game::Player.Health);
echo($Game::Player.RespawnPosition);


%file.writeLine("$SaveDir = " @ $SaveDir);
%file.writeLine("sceneWindow2D.loadLevel( expandFilename($SaveDir) ); ");  
%file.writeLine("$PlayerHealth = " @ $Game::Player.Health @ ";");
%file.writeLine("$PlayerLives = " @ $Game::Player.Lives @ ";");
%file.writeLine("$PlayerPosition = " @ "\"" @ $Game::Player.Position @ "\"" @ ";");
%file.writeLine("$PlayerScore = " @ $Pref::Points @ ";");
%file.writeLine("$PlayerRespawnPoint = " @ "\"" @ $Game::Player.RespawnPosition @ "\"" @ ";");
   
echo("Sucess! " @ %file);
good();
}
else  
{  
error("File is not open for saving!");
      Canvas.PushDialog(AreYouSure2Gui);
      $AYSText = "<just:center>The data you have attempted to save appears to be corrupt. If problem persists, try to reinstall the game. Sorry, bud. No, I will not offer any cheats. Press enter to dismiss the message.";

2. Cleaned up my code a bit, added account functionality and it now saves more variables including the checkpoint.
