hello!

 

How I can edit the code to generate blocks on top grass on the surface?

 

	private void runGenerator(WorldGenerator generator, World world, Random rand, int chunk_X, int chunk_Z, int chancesToSpawn, int minHeight, int maxHeight) {
    if (minHeight < 0 || maxHeight > 256 || minHeight > maxHeight)
        throw new IllegalArgumentException("Illegal Height Arguments for WorldGenerator");

    int heightDiff = maxHeight - minHeight + 1;
    for (int i = 0; i < chancesToSpawn; i ++) {
        int x = chunk_X * 16 + rand.nextInt(16);
        int y = minHeight + rand.nextInt(heightDiff);
        int z = chunk_Z * 16 + rand.nextInt(16);
        generator.generate(world, rand, x, y, z);
        System.out.printf("Cosa generada veinti");
    }
}

 

pss edit my code, many thanks!

u will need to find the surface block, I am not sure if vanilla has a method for that, or if u need to iterate over the blocks in the world until u find a grass block. after that add 1 to the y pos and u are above the grass

yes...

if someone bothers to edit my code, I would greatly appreciate it, i dont know how make this...

show ur attempts, ask specific questions

i use the last code for the ores generator, but i need make a replicate  the same code for generate blocks on the surface and on top the grass block

 

this is the .java

 

package com.colorescraftmod.principal.items;

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.init.Blocks;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import net.minecraft.world.gen.feature.WorldGenerator;

import cpw.mods.fml.common.IWorldGenerator;

public class ModWorldGen implements IWorldGenerator {

  private WorldGenerator multiore;		//Generates Multi Ore (used in Overworld)


public ModWorldGen() {
    this.multiore = new WorldGenSingleMinable(ModItems.multiore);
   // this.gen_cobblestone = new WorldGenMinable(Blocks.cobblestone, 16, Blocks.end_stone);
}

@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {
	switch (world.provider.dimensionId) {
	case 0: //Overworld
		//this.runGenerator(this.gen_multi_ore, world, random, chunkX, chunkX, 20, 0, 64); 

		this.runGenerator(this.multiore, world, random, chunkX, chunkZ, 1120, 0, 254);

		break;
	case -1: //Nether

		break;
	case 1: //End

		break;
	}
}


private void runGenerator(WorldGenerator generator, World world, Random rand, int chunk_X, int chunk_Z, int chancesToSpawn, int minHeight, int maxHeight) {
    if (minHeight < 0 || maxHeight > 256 || minHeight > maxHeight)
        throw new IllegalArgumentException("Illegal Height Arguments for WorldGenerator");

    int heightDiff = maxHeight - minHeight + 1;
    for (int i = 0; i < chancesToSpawn; i ++) {
        int x = chunk_X * 16 + rand.nextInt(16);
        int y = minHeight + rand.nextInt(heightDiff);
        int z = chunk_Z * 16 + rand.nextInt(16);
        generator.generate(world, rand, x, y, z);
        System.out.printf("Cosa generada veinti");
    }
}
}

so u have copy pasted code from TheBedrockMiner.

yes... but you can help me? xDD

not until u understood what hes doing there and are able to ask me a specific question. im not gonna write ur mod 4 u

Are you creating a surface ore? If you are than perhaps you could create a method for your y coordinate that creates a blockPos list of all the blocks in the x z area that is randomized by your code, then iterate through it till the block type is grass, then add 1, and you should have it.

Just a suggestion. Also, please know what you are saying before you post, it really helps everyone else.

only need a function for generate blocks on the surface... is only edit the last code... no make all the code

i don't know program anything :C

the code u posted is not even urs. study more and come back with a question

my question is on my first post...

u will need to find the surface block, I am not sure if vanilla has a method for that, or if u need to iterate over the blocks in the world until u find a grass block. after that add 1 to the y pos and u are above the grass

 

and i answered that

but this no help me because i don't know how edit the code,i don't know program anything 

we wont write ur mod 4 u.

If u want to write ur own mod learn java. then come back. or find some1 u can pay to write ur mod. but dont expect us to help u without u learning java.

maybe someone already has something similar to what I want or can spend a tutorial

If you want to learn how to generate blocks on the surface look in WorldGenTallGrass to see how it is done there.
