The title pretty much says it all.

 

I have made a class that extends WorldSavedData but i don't know how register it.

Googled a bit about how to save and load custom data on a world and found out that i should use that class.

 

How do i register or "activate" the class i have made?

 

MyWorldSavedData class

 

package mods.dnd91.minecraft.hivecraft;

 

import java.util.Iterator;

 

import net.minecraft.nbt.NBTTagCompound;

import net.minecraft.village.Village;

import net.minecraft.world.World;

import net.minecraft.world.WorldSavedData;

import net.minecraft.world.storage.MapStorage;

 

public class HiveCraftWorldData extends WorldSavedData {

 

final static String key = "HiveCraft.World.Data";

 

public static HiveCraftWorldData forWorld(World world) {

        // Retrieves the MyWorldData instance for the given world, creating it if necessary

MapStorage storage = world.perWorldStorage;

HiveCraftWorldData result = (HiveCraftWorldData)storage.loadData(HiveCraftWorldData.class, key);

if (result == null) {

result = new HiveCraftWorldData();

storage.setData(key, result);

}

return result;

}

 

public int tickCounter = 0;

 

public HiveCraftWorldData() {

super(key);

}

 

public void tick()

    {

        ++this.tickCounter;

        //Iterator iterator = this.villageList.iterator();

 

        /*while (iterator.hasNext())

        {

            Village village = (Village)iterator.next();

            village.tick(this.tickCounter);

        }

 

        this.removeAnnihilatedVillages();

        this.dropOldestVillagerPosition();

        this.addNewDoorsToVillageOrCreateVillage();*/

 

        if (this.tickCounter % 400 == 0)

        {

            this.markDirty();

        }

    }

 

@Override

public void readFromNBT(NBTTagCompound nbttagcompound) {

// TODO Auto-generated method stub

 

}

 

@Override

public void writeToNBT(NBTTagCompound nbttagcompound) {

// TODO Auto-generated method stub

 

}

 

}

 

 

 

Regards DND

 

EDIT:

With the TickHandlar im able to load the data with WORLDLOAD... but the class that extends WorldSavedData don't run the write and read functions.... for NTB.

Will i need to call the ticks function with a tickhandler or can i make forge do it for me? Thanks for the fast answer

Thanks for the help!

 

For ppl that are having problems with WorldSaveData as i did: Here is the code i used:

 

To the @Init i just added ... to the end:

TickRegistry.registerTickHandler(new TickHandler(), Side.SERVER);

 

TickHandler.java

 

package mods.dnd91.minecraft.hivecraft;

 

import java.util.EnumSet;

 

import net.minecraft.world.World;

 

import cpw.mods.fml.common.ITickHandler;

import cpw.mods.fml.common.TickType;

 

public class TickHandler implements ITickHandler {

 

 

public static HiveCraftWorldData worldData = null;

 

@Override

public void tickStart(EnumSet<TickType> type, Object... tickData) {

if(type.equals(EnumSet.of(TickType.WORLDLOAD))){

World world = null;

for(int i = 0; i < tickData.length; i++)

if(tickData instanceof World)

world = (World)tickData;

if(world == null){

return;

}

 

worldData = HiveCraftWorldData.forWorld(world);

worldData.markDirty();

}

}

 

@Override

public void tickEnd(EnumSet<TickType> type, Object... tickData) {

 

}

 

@Override

public EnumSet<TickType> ticks() {

// TODO Auto-generated method stub

return EnumSet.of(TickType.WORLDLOAD);

}

 

@Override

public String getLabel() {

// TODO Auto-generated method stub

return "HiveCraft_Ticker";

}

 

}

 

 

 

MyWorldSavedData.java

 

package mods.dnd91.minecraft.hivecraft;

 

import java.util.Iterator;

 

import net.minecraft.nbt.NBTTagCompound;

import net.minecraft.village.Village;

import net.minecraft.world.World;

import net.minecraft.world.WorldSavedData;

import net.minecraft.world.storage.MapStorage;

 

public class HiveCraftWorldData extends WorldSavedData {

 

final static String key = "HiveCraftWorldData";

 

public static HiveCraftWorldData forWorld(World world) {

        // Retrieves the MyWorldData instance for the given world, creating it if necessary

MapStorage storage = world.perWorldStorage;

HiveCraftWorldData result = (HiveCraftWorldData)storage.loadData(HiveCraftWorldData.class, key);

if (result == null) {

result = new HiveCraftWorldData();

storage.setData(key, result);

}

return result;

}

 

public HiveCraftWorldData() {

super(key);

}

 

public HiveCraftWorldData(String key){

super(key);

}

 

@Override

public void readFromNBT(NBTTagCompound nbttagcompound) {

System.out.println("READ!");

// TODO Auto-generated method stub

 

}

 

@Override

public void writeToNBT(NBTTagCompound nbttagcompound) {

System.out.println("WRITE!");

// TODO Auto-generated method stub

 

}

 

}

 

 

 

 

Should anybody look for it (to make a tutorial or something), in 1.8 there is no more :

MapStorage storage = world.perWorldStorage;

there is instead :

MapStorage storage = world.getPerWorldStorage();

Yes, I know, it does pop-up in search though. Besides I still cannot get it to work...
