Hello All;

 

at 1.7.10 we use this to generate blocks;

 

package net.extend.mod.functions;

import java.util.Random;

import net.extend.mod.blockref;
import net.extend.mod.configref;
import net.minecraft.block.Block;
import net.minecraft.block.state.IBlockState;
import net.minecraft.init.Blocks;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import net.minecraftforge.fml.common.IWorldGenerator;

public class generation implements IWorldGenerator {

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

	switch (world.provider.getDimensionId()) {
	case -1:
		generateNether();
		break;
	case 0:
		//generateSurface(world, random, chunkX * 16, chunkZ * 16, blockref.acidOre, 5, 50);
		generateSurface(world, random, chunkX * 16, chunkZ * 16, blockref.blackDiamondOre, 4, 12);
		generateSurface(world, random, chunkX * 16, chunkZ * 16, blockref.nightOre, 3, 10);
		break;
	case 1:
		generateEnd();
		break;
	}
}

//generateSurface(WORLD, RANDOM, CHUNKX * 16, CHUNKY * 16, AcidMod.ore.blockID, AMOUNT, Y)
public void generateSurface(World world, Random random, int chunkX, int chunkZ, Block str, int amount, int chunkY) {
	for (int i=0; i < 20; i++) {
		int oreX = chunkX + random.nextInt(16);
		int oreY = random.nextInt(chunkY);
		int oreZ = chunkZ + random.nextInt(16);
		(new WorldGenMinable(str, amount)).generate(world, random, oreX, oreY, oreZ);
	}
    }

 

But in 1.8 version, we need to use BlockPos, but in here we calculate X, Y and Z's coordinates to place, so how can I update this X, Y, Z to BlockPos?

 

Edit: also when I add new block, what is it's block state? how can I use it?

Look at the BlockPos class' code. The constructor can take in x, y, z and there are methods to get those back.

Ah yes you true, I fixed it thanks and also my block is extend by Block so how can I replace in this code to IBlockState or how can I get it?

 

I fixed it like

IBlockState state = (IBlockState)str.getBlockState();

 

But I am not sure if it is work or not. Anyway, what is the BlockState holds on? I saw some different code like "world.getBlockState(BlockPos)", can I use this like;

 

if world.getBlockState(BlockPos) == Block.coal_ore

 

These are very different, we need to learn everything in every version uh. Is there any documentations about new functions n 1.8

It is replacement of metadata in 1.8; So Block#getBlockState() just gives base state of the block, which is fairly wrong.

So you should use World#getBlockState(BlockPos).

And for coal ore, comparing block instance is just fine. Don't compare IBlockState and Block, they are completely different object.

Oh, not I mean like this;

 

I have a code like this;

				if (world.getBlock(x1, y1, z1) == Blocks.coal_ore) {
					found.add(new int[] { x1, y1, z1 });
				}

 

But there is no getblock in 1.8 so if I change this to;

 

                                        BlockPos pos1 = new BlockPos(x1, y1, z1);
				if (world.getBlockState(pos1) == Blocks.coal_ore.getBlockState()) {
					found.add(new int[] { x1, y1, z1 });
				}

 

Is it work correctly?

 

And also you said blockstate and Iblockstate is very different so how can I fix my worldminable code

 

public void generateSurface(World world, Random random, int chunkX, int chunkZ, Block str, int amount, int chunkY) {
	for (int i=0; i < 20; i++) {
		int oreX = chunkX + random.nextInt(16);
		int oreY = random.nextInt(chunkY);
		int oreZ = chunkZ + random.nextInt(16);
		BlockPos pos1 = new BlockPos(oreX, oreY, oreZ);
		IBlockState state = (IBlockState)str.getBlockState();
		(new WorldGenMinable(state, amount)).generate(world, random, pos1);
	}
    }

I did something like this

 

		generateSurface(world, random, chunkX * 16, chunkZ * 16, blockref.blackDiamondOre, 4, 12);
		generateSurface(world, random, chunkX * 16, chunkZ * 16, blockref.nightOre, 3, 10);

                                        BlockPos pos1 = new BlockPos(x1, y1, z1);
				if (world.getBlockState(pos1) == Blocks.coal_ore.getBlockState()) {
					found.add(new int[] { x1, y1, z1 });
				}

 

Not sure if that will work, however I know this will work

 

                                        BlockPos pos1 = new BlockPos(x1, y1, z1);
				if (world.getBlockState(pos1).getBlock() == Blocks.coal_ore) {
					found.add(new int[] { x1, y1, z1 });
				}

 

As for your second issue I don't know world gen, sorry.

Ah thank you I hope it works, I can try it after I fixed all of my errors because I am trying to update my items from 1.7.10 to 1.8.0 so it little bit hard. What about second question, how can I get IBlockState for custom block.

 

There is a function like getBlockState but it isn't IBlockState so how can I get it?

 

I found a function like this;

 

world.getBlockState(BlockPos) : IBlockState

 

and I tried like this;

 

BlockPos pos1 = new BlockPos(oreX, oreY, oreZ);
(new WorldGenMinable(world.getBlockState(pos1), amount)).generate(world, random, pos1);

 

It works without error, I am not sure but if there is someone stuck about this maybe help them.

 

Thanks for help.
