When I do

 

block = GameRegistry.findBlock("minecraft", "chest");

 

it returns null.

 

For all I can see in the GameData class is that it should work. Getting the UniqueIdentifier from a blockstate works perfectly so they are in there.. Yet they don't match when I try to get the block later.

 

Does anyone have a workaround for it?

if I look at the logs the chest does get added, which the unique id implies to by giving back the name and modid.

 

[17:55:18] [Client thread/TRACE] [FML/]: Registry add: minecraft:chest 54 net.minecraft.block.BlockChest@1f440e7 (req. id 54)

 

so it is in the registry, but the findblock doesnt find it in the minecraft:chest combo. Going to try to open up by reflection the class now to see whats going on...

For those interested I found out the error occurs in the containsKey method. that always returns false.

 

to get an object out of it though, you can use this.

 

 

              Class gdClass = GameData.class;
		try {
		Method method = gdClass.getDeclaredMethod("getMain");
		method.setAccessible(true);
		GameData gamedata = (GameData)method.invoke(null);
		FMLControlledNamespacedRegistry<Block> b = gamedata.getBlockRegistry();
		Loggingthingy.log.warn(b.getKeys());// All the keys are there...
		Block found = b.getObject("minecraft:chest");
		if(found != Blocks.air) {// maybe add a check if you want an air block...
			// Do something with found, whatever..
		}
	}
	catch(Exception ex) {
		ex.printStackTrace();
	}

 

Now, to figure out where to submit a bug report....

Figured out how to submit a bug ish ;-)

for those who just want to stay in the findBlock flow, I made this method.

 

Tweak as you see fit

 

/**
 * Tries to approach all legit ways to get a block from the game registry
 * but will go hackish when needed to to get the desired result.
 * @param modid String The modname
 * @param blockname String the block name
 * @return Blocks.air on not finding anything or the desired block.
 */
public static Block findBlock(String modid,String blockname) {
	Block find = GameRegistry.findBlock(modid,blockname);
	// legit way fails?
	if(find == null) {
		String searchkey = modid+":"+blockname;
		// Lets fire up the reflection...
		// You might want to put the map somewhere so you
		// don't have to reflect every time. saves a lot of cpu time.
		Class x = GameData.class;
			try {
				Method method = x.getDeclaredMethod("getMain");
				method.setAccessible(true);
				GameData gamedata = (GameData)method.invoke(null);
				// and I mean saving the below list b
				FMLControlledNamespacedRegistry<Block> b = gamedata.getBlockRegistry();
				// lets be gracious and give it a chance to find it this way
				if(b.containsKey(searchkey)) {
					find = b.getObject(searchkey);
				}
				else {
					// take a wild stab. returns air if nothing found
					find = b.getObject(searchkey);
					if(find != Blocks.air) {
						WhoTookMyCookies.log.warn("Chest found: "+GameRegistry.findUniqueIdentifierFor(b.getObject("minecraft:chest")).name);
					}
					else {
						if(!searchkey.equals("minecraft:air")) {
							// this is where we go and cry.
							// you can choose to leave find air which it is at this point
							// or set it to null...
						}
					}
				}
			}
			catch(Exception ex) {
				// your error handling here
			}
		}

	return find;
}
