Here is my code.

public class ItemInfoHandler 
{

public static boolean found;
public static int matchedId;
public static String matchedName;
public static String matchedModId;

// This matches the held item with an ID.	
public static void idMatcher(EntityPlayer player)
{	
		matchedId = (player.getHeldItem().itemID);
		matchedName = (player.getHeldItem().getDisplayName());
}

private static ItemData itemList(NBTBase base) 
{
	//Auto-generated method stub
	return null;
}

// This gets the NBT info

public static void getInfo(EntityPlayer player)
{	


	NBTTagList itemList = new NBTTagList();

	GameData.writeItemData(itemList);

	ArrayList<ItemData> data = new ArrayList();

	NBTBase base;

	NBTFinder:
	for(int i = 0; i < itemList.tagCount(); i++)
	{

		base = itemList.tagAt(i);

		if(base instanceof NBTTagCompound)
		{
			found = false;
			data.add(itemList(base));

					for (int x = 0; x < WikiLinkableHandler.modIdList.size(); x++)
					{
						// Does this item correspond with a registered mod ID?
						if((base).toString().contains("ModId:" + ((WikiLinkableHandler.modIdList).get(x))) && (base).toString().contains("ItemId:" + matchedId))
						{
							String currentLanguage = Minecraft.getMinecraft().gameSettings.language;
							System.out.println(WikiLinkableHandler.localizationList.get(x));

							if((WikiLinkableHandler.localizationList.get(x)).toString().equals(currentLanguage))
							{				
								String hyperlink = "http://" + WikiLinkableHandler.domainList.get(x) + WikiLinkableHandler.getSearchQuery(x) + matchedName.replace(" ", "+");

								//This needs to be localized.
								//player.addChatMessage("Searching for " + matchedName + " on the " + WikiLinkableHandler.nameList.get(x));

								BrowserHandler.browserInit(hyperlink, player);

								found = true;
								break NBTFinder;
							}
							else if(WikiLinkableHandler.localizationList.get(x).toString().equals(null) && found == false)
							{
								player.addChatMessage("Could not find wiki translation for your language: " + (Minecraft.getMinecraft().gameSettings.language));
								String hyperlink = "http://" + WikiLinkableHandler.domainList.get(0) + WikiLinkableHandler.getSearchQuery(0) + matchedName.replace(" ", "+");

								player.addChatMessage("Searching for " + matchedName + " on the " + WikiLinkableHandler.nameList.get(0));

								  BrowserHandler.browserInit(hyperlink, player);			  

								  found = true;
								  break NBTFinder;
							}
							else{continue;}
						}
						else{continue;}		
					}
		}

	}			
	if(found == false)
		{
			player.addChatMessage("Cannot find mod-related wiki to search! Searching default wiki.");

			player.addChatMessage("Could not find an accurate translation for your language: " + (Minecraft.getMinecraft().gameSettings.language));

			String hyperlink = "http://" + WikiLinkableHandler.domainList.get(0) + WikiLinkableHandler.getSearchQuery(0) + matchedName.replace(" ", "+");

			player.addChatMessage("Searching for " + matchedName + " on the " + WikiLinkableHandler.nameList.get(0));

			  BrowserHandler.browserInit(hyperlink, player);			  
		}
}	
}

 

and I'm getting the error on this line.

if((WikiLinkableHandler.localizationList.get(x)).toString().equals(currentLanguage))

 

I honestly have no explanation. The code worked earlier, but now it doesn't and I have no clue why. Anyone have any clues?

Why don't you do a null check before hand? That would fix that.

if ((WikiLinkableHandler.localizationList.get(x)).toString() != null)

// or was it?
if (!(WikiLinkableHandler.localizationList.get(x)).toString().equals(null))

 

Aside from that... I don't know.

 

 

 

What does the sysout print to the console??

I am Mew. The Legendary Psychic. I behave oddly and am always playing practical jokes.

 

I have also found that I really love making extremely long and extremely but sometimes not so descriptive variables. Sort of like what I just did there xD
