Loading and Saving problem in 2D space based rpg

Question

I am implementing a system in which the game saves the offset of the default position of an object in space and the object's position when the game is saved and applying that to the objects when the game is loaded. I get a strange problem however where every other undock after loading the game is far far away in space. I think it has something to do with the saved position of the object you docked with. Here is the code involved in loading the game (it just calls IO.java via dataAgent and gets data from a file)
public void loadGame() throws FileNotFoundException, IOException {
        //load the game
        String[] tmpData = null;
        tmpData = dataAgent.loadGame();
        //interpet the data
        hud.currentDockedCelestialObject = Integer.parseInt(tmpData[0]) - 1;
        player.currentWallet = Integer.parseInt(tmpData[1]) - 1;
        player.currentSolarSystem = space[hud.currentDockedCelestialObject].solar;
        hud.renderMode = 1;
        hud.player = player;
        hud.space = space;
        hud.dPressed = true; //tell HUD we are docked at something
        //now we need to determine the position of all the celestial objects based on the saved position of the object in question
        int tmpx = Integer.parseInt(tmpData[2]) - 1;
        int tmpy = Integer.parseInt(tmpData[3]) - 1;
        //compare it to the docked celestial
        int changex = space[hud.currentDockedCelestialObject].positionX - tmpx;
        int changey = space[hud.currentDockedCelestialObject].positionY - tmpy;
        //apply the offset to all the objects in the current solar system
        for (int i = 0; i < space.length; i++) {
            if (space.solar.matches(player.currentSolarSystem)) {
space[i].positionX += changex;
space[i].positionY += changey;
//now we need to load the ship type
player.ship.type = Integer.parseInt(tmpData[4]);
//configure the shields and hulls
configureLoadedShip();
//finish up
hud.space = space;
hud.player = player;
Configureloadedship() just makes a call to apply the correct weapons and armor to the ship you have. Here is the saving code:public void saveGame() {
//saves the game
String[] toSave = new String[5];
toSave[0] = "" + (hud.currentDockedCelestialObject + 1);
toSave[1] = "" + (hud.player.currentWallet + 1);
toSave[2] = "" + (space[hud.currentDockedCelestialObject].positionX);
toSave[3] = "" + (space[hud.currentDockedCelestialObject].positionY);
toSave[4] = "" + (hud.player.ship.type);
try {
dataAgent.saveGame(toSave);
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
Adding and subtracting 1 durring load and save solved the problem of the java file reader skipping the 0 values in the first few lines of the saved game file.
The game is loaded when the game starts and saved when you dock.
Ty in advance for your help.

Answer 1

public String[] loadGame() throws FileNotFoundException, IOException /*should never be thrown*/ {
        String[] toReturn = null;
        //load the data
        FileReader read = new FileReader(data);
        BufferedReader buff = new BufferedReader(read);
        String tmp1 = "";
        String tmp2 = "";
        while((tmp1 = buff.readLine())!=null) {
            tmp2 = tmp2 + tmp1+"~";
        //break it into a usable form
        toReturn = tmp2.split("~");
        System.out.println(tmp2);
        return toReturn;
    }and
public void saveGame(String[] toSave) throws IOException {
        FileWriter write = new FileWriter(data);
        BufferedWriter buff = new BufferedWriter(write);
        //clear the old file
        data.delete();
        data.createNewFile();
        //zap the data to the file
        for(int i = 0; i < toSave.length; i++) {
            buff.write(toSave);
buff.newLine();
//write
buff.flush();
}They are basically just buffered readers and writers.
