Hi,

How do i save information in the World?

I have no idea, i got really confused.

Would be very nice, if someone could help me.

http://www.minecraftforge.net/forum/index.php/topic,5483.msg29791.html#msg29791

But how can i make a file in Java?

ok, so far so good.

But how i have to go on?

package randomadditions;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.WorldSavedData;

public class WorldSaveRandomData extends WorldSavedData{

public WorldSaveRandomData(String par1Str) {
	super(par1Str);
}

@Override
public void readFromNBT(NBTTagCompound var1) {
	RandomAdditions.WorldVersion = var1.getDouble("RAV");
}

@Override
public void writeToNBT(NBTTagCompound var1) {
	var1.setDouble("RAV", RandomAdditions.ModVersion);
}

}

here is my world save data:

package legendz.common;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;
import net.minecraft.world.WorldSavedData;
import net.minecraft.world.storage.MapStorage;

public class WorldSaveData extends WorldSavedData {

public static boolean[] alreadyGenerated = new boolean[8];

public WorldSaveData(String par1Str) {
	super(par1Str);
}

@Override
public void readFromNBT(NBTTagCompound nbt) {
	for(int i = 0; i < alreadyGenerated.length; i++){
		alreadyGenerated[i] = nbt.getBoolean("generated"+i);
	}
}

@Override
public void writeToNBT(NBTTagCompound nbt) {
	for(int i = 0; i < alreadyGenerated.length; i++){
		nbt.setBoolean("generated"+i, alreadyGenerated[i]);
	}
}

}

 

i call it in the generate method so structures will only be generated once.

here is the code where i call it:

if(world.loadItemData(WorldSaveData.class, "LegendzWorldSaveData") == null){
		WorldSavedData data = new WorldSaveData("LegendzWorldSaveData");
		world.setItemData("LegendzWorldSaveData", data);
	}

	worldSaveData = (WorldSaveData) world.loadItemData(WorldSaveData.class, "LegendzWorldSaveData");

 

hope this makes it a little more clear for you.

i had the same trouble figuring out how to store data in the world and is was a pain in the @$$
