Hello,

 

can you guys help me fix this? It isn't working. I'm trying to make a global warming mod for minecraft as a school project, yet I cannot update an index that is meant to be saved and loaded. Here's my code:

package greg;

import java.util.ArrayList;
import java.util.Timer;
import java.util.TimerTask;

import net.minecraft.block.*;
import net.minecraft.block.state.IBlockState;
import net.minecraft.util.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.storage.WorldInfo;
import net.minecraftforge.event.world.BlockEvent.BreakEvent;
import net.minecraftforge.event.world.BlockEvent.PlaceEvent;
import net.minecraftforge.fml.common.Mod.EventHandler;

public class ModEventHandler {

public ArrayList<PollutionLevel> list = new ArrayList<PollutionLevel>();

FileFunctions files = new FileFunctions();

public static int pollutionIndex;
ArrayList<World> initialWorld;
WorldInfo infoWorld = new WorldInfo() {};
public static String worldName;
public static int integer;

public void load(World world){

	worldName = infoWorld.getWorldName();
	int ind;
	files.ReadFromFile(list);

	if(!list.contains(worldName))
	{
		pollutionIndex = 0;     
	}
	else
	{
		ind = list.indexOf(worldName);
		pollutionIndex = list.get(ind).getPol();
		//meant to set the correct pol level

	}
}
@EventHandler
public void onBlockDestroyedByPlayer(BreakEvent event)
{
	pollutionIndex = pollutionIndex + 2;
	if(event.state.getBlock().isWood(event.world, event.pos) == true)
	{
		pollutionIndex = pollutionIndex + 2;
	}
}

@EventHandler
public void onBlockPlacedByPlayer(PlaceEvent event)
{
	int ind;
	if(event.placedBlock.getBlock().isWood(event.world, event.pos) == true)
	{
		pollutionIndex = pollutionIndex - 1;

		if(!list.contains(worldName))
		{
			list.add(new PollutionLevel(worldName, pollutionIndex));
		}
		else
		{
			ind = list.indexOf(worldName);
			list.remove(ind);
			list.add(new PollutionLevel(worldName, pollutionIndex));
		}
	}
}
public void onBlockDestroyedByPlayer(World worldIn, BlockPos pos, IBlockState state) {
	pollutionIndex = pollutionIndex +2;
}

}

 

The onBlockDestroyedByPlayer is just testing to see if the class worked, but it doesn't so yeah. I really need help.

 

Here's my main class:

 

package greg;

import java.util.ArrayList;
import java.util.Timer;
import java.util.TimerTask;

import net.minecraft.client.Minecraft;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import net.minecraft.world.storage.WorldInfo;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.Mod.Instance;
import net.minecraftforge.fml.common.SidedProxy;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;

@Mod(modid=info.ID, name=info.NAME, version=info.VERS)


public class main {



@Instance(value = "mainID")
public static main instance;


@SidedProxy(clientSide=info.CLIENT + ".ClientProxy", serverSide=info.COMMON + ".CommonProxy")
public static CommonProxy proxy;

@EventHandler
public void preInit(net.minecraftforge.fml.common.event.FMLPreInitializationEvent event) {
	// Stub Method
	MinecraftForge.EVENT_BUS.register(new ModEventHandler());
}

@EventHandler
public void init(FMLInitializationEvent event){
	proxy.registerRenderers();

	MinecraftForge.EVENT_BUS.register(new ModEventHandler());
	MinecraftForge.EVENT_BUS.register(new HUDPol(Minecraft.getMinecraft()));

}


@EventHandler
public void postInit(net.minecraftforge.fml.common.event.FMLPostInitializationEvent event) {
	// Stub Method

}



}

 

Thanks!

For listening to events from event buses, use @SubscribeEvent. If you look at the Javadocs for @EventHandler, you would see that it is mainly used to manage the lifecycle of your mod

I changed it and now I get this crash-log:

Help?

Where do you call load(World)? Also, you should probably use a WorldSavedData for this.

 

Where should I call load(World)?

 

I don't think I am currently calling it

You should not be calling it at all, you should not be having it. You should be using WorldSavedData, as I said.

 

Can I modify the class? Or how do you suggest I implement it? I was planning on having my own ArrayList to store the data and then retrieve it, which is what the load(World) functions does. I was going to have the unload(World) function saving the data.
