Hey guys!

 

I have some problems spawning a test structure in the overworld.

 

 

WorldGenerator for the structure

 package "mypackage";

import java.util.Random;

int Xcoord = BlockX + random.nextInt(16);
int Zcoord = BlockZ + random.nextInt(16);

}
}

private void generateSurface1(World world, Random rand, int i, int j)
{
  for(int k = 0; k<1; k++)
  {
int RandPosX = i + rand.nextInt(16);
int RandPosY = rand.nextInt(128);	
int RandPosZ = j + rand.nextInt(16);
(new teststructure()).generate(world, rand, RandPosX, RandPosY, RandPosZ);
  }
}
}

 

 

And in my main file:

 

 GameRegistry.registerWorldGenerator(new WorldGeneratorSurface());

 

 

I get no errors, but I cant find this structure anywhere. Does anybody know what I did wrong?

But you're using a different method for generating your structure as you are your ore. You are calling generateStructure() for your ore in the case: 0 check, but from the code above it seems you're not calling generateStructure1() with your structure anywhere.

 

You need to call it from somewhere, be it the case statement of the end of the ore generating method.

changed it now to this:

 

package "";

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import cpw.mods.fml.common.IWorldGenerator;
import cpw.mods.fml.common.IWorldGenerator;


public class WorldGeneratorSurface implements IWorldGenerator {

@Override
public void generate(Random random, int chunkX, int chunkZ, World world,
IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {
switch(world.provider.dimensionId){
//case -1: generateNether(world, random,chunkX*16,chunkZ*16);
case 0 : generateSurface(world, random,chunkX*16,chunkZ*16);
}
}


private void generateSurface(World world, Random random, int BlockX, int BlockZ) {
for(int i =0; i<40;i++){
int Xcoord = BlockX + random.nextInt(16);
int Zcoord = BlockZ + random.nextInt(16);
int Ycoord = random.nextInt(16);

(new WorldGenMinable(Main."".blockID, 4)).generate(world, random, Xcoord, Ycoord, Zcoord);

for(int k = 0; k<1; k++)
{
int Xcoord1 = BlockX + random.nextInt(16);
int Ycoord1 = random.nextInt(60);
int Zcoord1 = BlockZ + random.nextInt(16);

(new teststructure()).generate(world, random, Xcoord1, Ycoord1, Zcoord1);

}
}
}}

 

still cant find it. Do you notice something else wrong?

ok guys I got it now. I post the code so maybe I can help someone.

 

WorldGenerator:

 

 package "package";

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import cpw.mods.fml.common.IWorldGenerator;
import cpw.mods.fml.common.IWorldGenerator;


public class WorldGeneratorSurface implements IWorldGenerator {

public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider)
{
switch (world.provider.dimensionId)
{
  //case -1: generateNether(world, random, chunkX*16, chunkZ*16);
  case 0: generateSurface(world, random, chunkX*16, chunkZ*16);
}

}

private void generateSurface(World world, Random rand, int l, int j)
{

for(int i =0; i<40; i++){
int Xcoord = l + rand.nextInt(16);
int Zcoord = j + rand.nextInt(16);
int Ycoord = rand.nextInt(16);

(new WorldGenMinable(Main.someore.blockID, 4)).generate(world, rand, Xcoord, Ycoord, Zcoord);

  for(int k = 0; k < 1; k++)
  {
int RandPosX = l + rand.nextInt(16);
int RandPosY = rand.nextInt(128);	
int RandPosZ = j + rand.nextInt(16);
(new teststructure()).generate(world, rand, RandPosX, RandPosY, RandPosZ);



}}}}

 

teststructure:

 

package""package;

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.world.World;
import net.minecraft.world.gen.feature.WorldGenerator;

public class teststructure extends WorldGenerator {

public teststructure()
{

}

public boolean generate(World world, Random rand, int x, int y, int z)
{
if(world.getBlockId(x, y, z)!= Block.sand.blockID || world.getBlockId(x, y + 1, z)!= 0)
   {
   return false;
   }

world.setBlock(x, y + 1, z, Main.someblock.blockID);
world.setBlock(x + 1, y + 1, z, Main.someblock.blockID);
world.setBlock(x, y + 2, z, Main.someblock.blockID);
world.setBlock(x + 1, y + 2, z, Main.someblock.blockID);
world.setBlock(x + 2, y + 2, z, Main.someblock.blockID);
world.setBlock(x - 1, y + 2, z, Main.someblock.blockID);
world.setBlock(x + 3, y + 3, z, Main.someblock.blockID);
world.setBlock(x - 2, y + 3, z, Main.someblock.blockID);
world.setBlock(x + 2, y + 3, z, Main.someblock.blockID);
world.setBlock(x - 1, y + 3, z, Main.someblock.blockID);
world.setBlock(x + 3, y + 4, z, Main.someblock.blockID);
world.setBlock(x - 2, y + 4, z, Main.someblock.blockID);
world.setBlock(x + 2, y + 4, z, Main.someblock.blockID);
world.setBlock(x - 1, y + 4, z, Main.someblock.blockID);
world.setBlock(x + 3, y + 5, z, Main.someblock.blockID);
world.setBlock(x - 2, y + 5, z, Main.someblock.blockID);
world.setBlock(x + 2, y + 5, z, Main.someblock.blockID);
world.setBlock(x - 1, y + 5, z, Main.someblock.blockID);
world.setBlock(x + 2, y + 6, z, Main.someblock.blockID);
world.setBlock(x - 1, y + 6, z, Main.someblock.blockID);
world.setBlock(x, y + 7, z, Main.someblock.blockID);
world.setBlock(x + 1, y + 7, z, Main.someblock.blockID);
world.setBlock(x, y + 6, z, Main.someblock.blockID);
world.setBlock(x + 1, y + 6, z, Main.someblock.blockID);
world.setBlock(x, y + 3, z, Main.someblock.blockID);

return true;
   }  
}

 

Code: "k < 1" 1 is the rarity. I placed 1 so I could find it fast when it spawns. With 1 you have min 1 of your structure per chunk.

          "if(world.getBlockId(x, y, z)!= Block.sand.blockID || world.getBlockId(x, y + 1, z)!= 0)" Block.sand.blockID is on what block it spawns. In this case sand

Why don't you use for loops for the block placement???

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

for(int x1 = -2; x1 < 2; x1++)
{
    world.setBlock(x-x1,y,z, BLOCK_OF_YOUR_CHOISE.blockID)
}

That code will spawn a straigt line of five blocks of your choise.
