Hey, It's me again and I have another question about storing things. Since my generated structure is spawned rarely, I want to make a command that will print out known locations of the structure. I figured out I have to save the coordinates when generating the structure. I think the MapStorage would be best to use, but I can't figure out how it works. These are my classes:

Data I'm Saving

 

public class CollectiblesWorldData extends WorldSavedData{

    private static final String identifier = Constants.MODID;

    public static int[] x;
    public static int[] y;
    public static int[] z;


    public  int getX(int i) {
        return x[i];
    }

    public  int getY(int i) {
        return y[i];
    }

    public  int getZ(int i) {
        return z[i];
    }

    public CollectiblesWorldData() {
        super(identifier);
    }

    public CollectiblesWorldData(String IDENTIFIER) {
        super(IDENTIFIER);
    }


    public void setBaseStructureCoords(int newx,int newy,int newz,int structureNumber){
        x[structureNumber-1] = newx;
        y[structureNumber-1] = newy;
        z[structureNumber-1] = newz;
        markDirty();
    }

    @Override
    public void readFromNBT(NBTTagCompound nbt) {
        x=nbt.getIntArray("x");
        y=nbt.getIntArray("y");
        z=nbt.getIntArray("z");
    }

    @Override
    public void writeToNBT(NBTTagCompound nbt) {
        nbt.setIntArray("x",x);
        nbt.setIntArray("y",y);
        nbt.setIntArray("z",z);
    }
}

 

Part of the code where I edit the data and the save it:

 

public class WorldGenBaseStructure {
    static Configuration config = new Configuration(Collectibles.configfile);
    private static int i = 1;
    static CollectiblesWorldData cwd = new CollectiblesWorldData();                            //<------HERE
    public static void generate(World world, Random random, int x, int y, int z) {

        config.load();
        if (world.getBlock(x, y, z) == Blocks.grass || world.getBlock(x, y, z) == Blocks.sand || world.getBlock(x, y, z) == Blocks.dirt || world.getBlock(x, y, z) == Blocks.gravel) {
            if (world.getBlock(x, y, z + 9) == Blocks.grass || world.getBlock(x, y, z + 9) == Blocks.sand || world.getBlock(x, y, z + 9) == Blocks.dirt || world.getBlock(x, y, z + 9) == Blocks.gravel) {
                if (world.getBlock(x + 9, y, z) == Blocks.grass || world.getBlock(x + 9, y, z) == Blocks.sand || world.getBlock(x + 9, y, z) == Blocks.dirt || world.getBlock(x + 9, y, z) == Blocks.gravel) {
                    if (world.getBlock(x + 9, y, z + 9) == Blocks.grass || world.getBlock(x + 9, y, z + 9) == Blocks.sand || world.getBlock(x + 9, y, z + 9) == Blocks.dirt || world.getBlock(x + 9, y, z + 9) == Blocks.gravel) {
                    }
                }
                //System.out.println("Found suitable space on " + x + ", " + y + ", " + z);
                if ((!config.hasKey(config.CATEGORY_GENERAL, "generated3In_" + world.getWorldInfo().getWorldName()))) {         //||(world.getBlock(x+3,y+1,z) != Blocks.stonebrick)
                    System.out.println("Generating on " + x + ", " + y + ", " + z);
                    cwd.setBaseStructureCoords(x, y, z, i);                                                //<------HERE
                    world.mapStorage.setData(Constants.MODID,cwd);                            //<------HERE
                    config.get(config.CATEGORY_GENERAL, "generated" + i + "In_" + world.getWorldInfo().getWorldName(), true);
                    config.save();
                    i++;

 

My processCommand method:

 

@Override
    public void processCommand(ICommandSender sender, String[] args) {
    if (args.length == 1){
        if (sender instanceof EntityPlayer){

                CollectiblesWorldData savedData = new CollectiblesWorldData();
                savedData = (CollectiblesWorldData) sender.getEntityWorld().mapStorage.loadData(CollectiblesWorldData.class, Constants.MODID);
                EntityPlayer player = (EntityPlayer) sender;
                int x = (int)savedData.getX(Integer.parseInt(args[0]));
                int y = (int)savedData.getY(Integer.parseInt(args[0]));
                int z = (int)savedData.getZ(Integer.parseInt(args[0]));
                player.addChatMessage(new ChatComponentText(Integer.toString(x)));

                player.addChatMessage(new ChatComponentText(Integer.toString(y)));

                player.addChatMessage(new ChatComponentText(Integer.toString(z)));
            }
        }
        else{
        sender.addChatMessage(new ChatComponentText("§cYou have typed this command wrong! Use §2/help srl"));
    }
    }

 

 

And This is the error I get (It crashes always when the structure should be generated):

The integer arrays are null. You need to initialize them.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.
