[1.7.2] World Gen crashes game

[Budboy33]

I've been having some troubles with world generation, i'm trying to generate a structure in a plains biome, but whenever I generate new chunks the game crashes

 

 

Init Code:

 

 

public static SpawnWorldGen worldGen = new SpawnWorldGen();

public void doSomething() {

 

}

public void preInit() {

swordTraining = new ItemSwordTraining(toolTraining);

 

GameRegistry.registerItem(swordTraining, "swordTraining");

}

public void Init() {

        GameRegistry.registerWorldGenerator(worldGen, 0);

}

}

 

 

World Gen Code

 

package com.budboy.mrpg.worldgen;

 

import java.util.Random;

 

import net.minecraftforge.event.terraingen.*;

import net.minecraft.world.World;

import net.minecraft.world.biome.BiomeGenBase;

import net.minecraft.world.chunk.IChunkProvider;

import cpw.mods.fml.common.IWorldGenerator;

 

public class SpawnWorldGen implements IWorldGenerator {

 

        @Override

        public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {

         

        BiomeGenBase b = world.getBiomeGenForCoords(chunkX, chunkZ);

              if(b.biomeName.equals("Plains")) {

              world.setBlock(chunkX*16 + random.nextInt(16), 100, chunkZ*16 + random.nextInt(16), null, 5, chunkZ);

        }

 

}

}

[Parker8283]

Well make sure in PreInit and Init you have the @EventHandler annotation over each method and that PreInit receives the FMLPreInitializationEvent parameter and that Init receives the FMLInitializationEvent parameter.

[GotoLink]

world.setBlock(chunkX*16 + random.nextInt(16), 100, chunkZ*16 + random.nextInt(16), null, 5, chunkZ);

Blocks can't be null in 1.7.

[Budboy33]

My 1 item is loading during PreInit, so the worldgen should be loading, and also how do I fix the null thing?

Edit: Whenever I try to get rid of 'null,' it gives an error that reverts it back when I fix it

[coolboy4531]

What are you trying to change null into?

It shouldn't just change back by itself... -.-'
