HELP! GETS BLOCKS IN AREA!

Hey there I'm working on a client side bot mod that I want to be able to search loaded nearby chunks for a particular block type, although currntly I'm unable to find a way to loop through loaded chunks / blocks.

 

Help would be greatly appreciated.

 

 

I've decided to upload the class files instead of pasting them as there are quite a few.

The main class I'm using for the searching nearby chunks client side:

 

package com.jakenelson1999.cactusbot.tasks;

import com.jakenelson1999.cactusbot.CactusBot;
import com.jakenelson1999.cactusbot.CactusController;
import com.jakenelson1999.cactusbot.CactusTask;

import net.minecraft.client.Minecraft;
import net.minecraft.init.Blocks;
import net.minecraftforge.common.util.BlockSnapshot;

public class SearchForSpawner implements CactusTask {

	public boolean taskComplete = false;

	public SearchForSpawner(double destx, double desty, double destz, boolean walktoloc) {
		CactusController.setDelay(5000);
	}

	@Override
	public String getTaskName() {
		
		return "Spawner Find";
	}

	@Override
	public String getTaskDescription() {
		
		return "Finds a spawner by walking across the top of the nether.";
	}

	@Override
	public boolean isTaskComplete() {
		
		return taskComplete;
	}

	@Override
	public void taskTick() {
		testDetect();
		
	}

	@Override
	public void endTask() {
		
		
	}
	
	
	public boolean testDetect(){
		
		/* This part here is not functioning! :( */
		
		CactusBot.printToChat("Task tick!");
		for(BlockSnapshot b : Minecraft.getMinecraft().theWorld.capturedBlockSnapshots){
			if(b.getCurrentBlock().getBlock().getMaterial().equals(Blocks.mob_spawner.getMaterial())){
				CactusBot.printToChat("Mob Spawner detected!!");
			}
			CactusBot.printToChat(b.getCurrentBlock().getBlock()+"");
		}
		
		
		return true;
		
	}
	

	
	} 

Note: I've setup an interface for bot tasks, although it's a WIP.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

You can't do server things from the client.

So I'm currently using WorldDownloader's reflection utils which work wonders:

package com.jakenelson1999.cactusbot.utils;

import java.lang.reflect.Field;

/**
 * Reflection utilities.
 */
public class ChunkUtils {

	/**

	 *            The type of the field
	 * @return An Object of type Field
	 */
	public static Field stealField(Class<?> typeOfClass, Class<?> typeOfField) {
		Field[] fields = typeOfClass.getDeclaredFields();
	
		for (Field f : fields) {
			if (f.getType().equals(typeOfField)) {
				try {
					f.setAccessible(true);
					return f;
				} catch (Exception e) {
					throw new RuntimeException(
						"WorldDownloader: Couldn't steal Field of type \""
						+ typeOfField + "\" from class \"" + typeOfClass
						+ "\" !", e);

To go through all loaded chunks you may simply do:

	public boolean isSpawnerNearby() {

		CactusBot.printToChat("Task tick!");

		// Get the ChunkProviderClient from WorldClient
		ChunkProviderClient chunkProvider = (ChunkProviderClient) Minecraft.getMinecraft().theWorld.getChunkProvider();

		// Get the list of all loaded chunks.
		List<?> chunks = ChunkUtils.stealAndGetField(chunkProvider, List.class);

		for (int currentChunk = 0; currentChunk < chunks.size(); currentChunk++) {
			Chunk c = (Chunk) chunks.get(currentChunk);

			for (int xx = 0; xx < 16; xx++) {
				for (int zz = 0; zz < 16; zz++) {
					for (int yy = 0; yy < 256; yy++) {
						Block block = c.getBlock(xx, yy, zz);
						if (block instanceof BlockMobSpawner) {
							CactusBot.printToChat("Found mob spawner " + xx + ", " + yy + ", " + zz);
							CactusBot.printToChat("chunk x start " + c.getChunkCoordIntPair().getXStart());
							CactusBot.printToChat("chunk y start " + c.getChunkCoordIntPair().getZStart());

							return true;
						}

					}
				}
			}

		}

		return false;

	}
