[1.10.2] How to get World and make it compatible both server and client side?

[SanaRinomi]

How can I get World so that I can generate glowstone in the Nether or Ores overworld, while keeping the compatibility both server and client side? Thanks in advanced!

First you could register a world generator or you could use the generation events

I'm using for normal ores WorldGenerator, but I also have a Glowstone class because I've added purple glowstone.

 

Here's my ModWorld class:

 

package com.holydevils.world;

import java.util.Random;

import com.holydevils.world.special.PurpleGlowstoneNetherGenOne;
import com.holydevils.world.special.PurpleGlowstoneNetherGenTwo;

import net.minecraft.server.MinecraftServer;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkGenerator;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenerator;
import net.minecraftforge.fml.common.IWorldGenerator;
import net.minecraftforge.fml.common.registry.GameRegistry;

public class ModWorld implements IWorldGenerator{

public static void worldRegistry(){

}

public static void initializeWorldGen(){
	generateSpecial();
}

public static void generateSpecial(World world){
	switch(world.provider.getDimension()){
	case -1: //Nether
		new PurpleGlowstoneNetherGenOne();
		new PurpleGlowstoneNetherGenTwo();
		break;
	case 0: //Overworld

		break;
	case 1: //End

		break;
	}
}

@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator,
		IChunkProvider chunkProvider) {
	switch(world.provider.getDimension()){
	case -1: //Nether
		new PurpleGlowstoneNetherGenOne();
		new PurpleGlowstoneNetherGenTwo();
		break;
	case 0: //Overworld

		break;
	case 1: //End

		break;
	}
}

private void registerWorldGen(WorldGenerator worldGen, World world, Random random, int chunkX, int chunkZ, int chanceToSpawn, int minY, int maxY){
	if(minY < 0 || maxY >world.getHeight() || minY > maxY)
		throw new IllegalArgumentException("Minimum or Maximum Height out of bounds");
	int layerDiff = maxY - minY + 1;
	for(int i = 0; i < chanceToSpawn; i++){
		int x = chunkX * 16  + random.nextInt(16);
		int y = minY + random.nextInt(layerDiff);
		int z = chunkZ * 16  + random.nextInt(16);
		worldGen.generate(world, random, new BlockPos(x, y, z));
	}
}
}

 

generateSpecial will give off errors but that's because I hadn't put in World and that why I consulted you to make it both server and client side.

 

And these are both Glowstone Generation classes:

 

 

PurpleGlowstoneNetherGenOne class:

package com.holydevils.world.special;

import java.util.Random;

import com.holydevils.blocks.ModBlocks;

import net.minecraft.init.Blocks;
import net.minecraft.util.EnumFacing;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.gen.feature.WorldGenerator;

public class PurpleGlowstoneNetherGenOne extends WorldGenerator
{
    public boolean generate(World worldIn, Random rand, BlockPos position)
    {
        if (!worldIn.isAirBlock(position))
        {
            return false;
        }
        else if (worldIn.getBlockState(position.up()).getBlock() != Blocks.NETHERRACK)
        {
            return false;
        }
        else
        {
            worldIn.setBlockState(position, ModBlocks.purpleGlowstone.getDefaultState(), 2);

            for (int i = 0; i < 1500; ++i)
            {
                BlockPos blockpos = position.add(rand.nextInt( - rand.nextInt(, -rand.nextInt(12), rand.nextInt( - rand.nextInt();

                if (worldIn.isAirBlock(blockpos))
                {
                    int j = 0;

                    for (EnumFacing enumfacing : EnumFacing.values())
                    {
                        if (worldIn.getBlockState(blockpos.offset(enumfacing)).getBlock() == ModBlocks.purpleGlowstone)
                        {
                            ++j;
                        }

                        if (j > 1)
                        {
                            break;
                        }
                    }

                    if (j == 1)
                    {
                        worldIn.setBlockState(blockpos, ModBlocks.purpleGlowstone.getDefaultState(), 2);
                    }
                }
            }

            return true;
        }
    }
}

 

PurpleGlowstoneNetherGenTwo class:

package com.holydevils.world.special;

import java.util.Random;

import com.holydevils.blocks.ModBlocks;

import net.minecraft.block.Block;
import net.minecraft.init.Blocks;
import net.minecraft.util.EnumFacing;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.gen.feature.WorldGenerator;

public class PurpleGlowstoneNetherGenTwo extends WorldGenerator
{
    public boolean generate(World worldIn, Random rand, BlockPos position)
    {
        if (!worldIn.isAirBlock(position))
        {
            return false;
        }
        else if (worldIn.getBlockState(position.up()).getBlock() != Blocks.NETHERRACK)
        {
            return false;
        }
        else
        {
            worldIn.setBlockState(position, ModBlocks.purpleGlowstone.getDefaultState(), 2);

            for (int i = 0; i < 1500; ++i)
            {
                BlockPos blockpos = position.add(rand.nextInt( - rand.nextInt(, -rand.nextInt(12), rand.nextInt( - rand.nextInt();

                if (worldIn.isAirBlock(blockpos))
                {
                    int j = 0;

                    for (EnumFacing enumfacing : EnumFacing.values())
                    {
                        if (worldIn.getBlockState(blockpos.offset(enumfacing)).getBlock() == ModBlocks.purpleGlowstone)
                        {
                            ++j;
                        }

                        if (j > 1)
                        {
                            break;
                        }
                    }

                    if (j == 1)
                    {
                        worldIn.setBlockState(blockpos, ModBlocks.purpleGlowstone.getDefaultState(), 2);
                    }
                }
            }

            return true;
        }
    }
}

 

 

If you wonder why I have two, it's because Minecrafts normal Glowstone has two, so to be on the safe side, I implemented both.

Where do you need the world variable?

[SanaRinomi]

I need it in the ModWorld class

[Animefan8888]

I dont think you are going about this correctly. You create a class that implements IWorldGenerator that class handles what you are generating. You only need to put GameRegistry.registerWorldGenerator () in your init method.

Yeah! Thanks for the help!  :D
