I want to know how to retrieve the spawn location before generating a structure. Any thoughts? i was using the WorldInfo.getSpawnX() and getSpawnZ()

You could use world.getSpawnPoint() if you have the World object.

Now i have another problem: here is my code

 

Main mod class

package net.mrblockplacer.mike;

import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.Init;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.network.NetworkMod;
import cpw.mods.fml.common.registry.GameRegistry;

@Mod (modid = "genmod", name = "genmod", version = "0.0.1" )

@NetworkMod (clientSideRequired = true, serverSideRequired = false)
public class Genmod {

public static generation worldGen = new generation();

@Init
public void myLoadMethod(FMLInitializationEvent event)
{
GameRegistry.registerWorldGenerator(worldGen);
    }



}

 

World Generator class

package net.mrblockplacer.mike;

import java.util.List;
import java.util.Random;

import net.minecraft.src.Block;
import net.minecraft.src.Chunk;
import net.minecraft.src.ChunkPosition;
import net.minecraft.src.EnumCreatureType;
import net.minecraft.src.IChunkProvider;
import net.minecraft.src.IProgressUpdate;
import net.minecraft.src.World;
import net.minecraft.src.WorldInfo;
import cpw.mods.fml.common.IWorldGenerator;

public class generation implements IWorldGenerator {



@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {
	int spawnX = (world.getSpawnPoint().posX);
	int spawnZ = (world.getSpawnPoint().posZ);
	float spawnXdec = (float) spawnX;
	float spawnZdec = (float) spawnZ;
	spawnXdec = spawnXdec / 16;
	spawnZdec = spawnZdec / 16;
	int spawnchunkX = (int) spawnXdec;
	int spawnchunkZ = (int) spawnZdec;
	if (chunkX == spawnchunkX && chunkZ == spawnchunkZ) {

		for (int i = 0; i < 16; i++) {

			for (int j = 0; j < 16; j++) {
				world.setBlock(chunkX + i, 100, chunkZ + j, Block.planks.blockID);
			}

			for (int j = 0; j < 7; j++) {
				world.setBlock(chunkX + i, 100 + j, chunkZ, Block.planks.blockID);
				world.setBlock(chunkX + i, 100 + j, chunkZ + 15, Block.planks.blockID);
				world.setBlock(chunkX, 100 + j, chunkZ + i, Block.planks.blockID);
				world.setBlock(chunkX + 15, 100 + j, chunkZ + i, Block.planks.blockID);
			}
		System.out.println("spawning");
		}


		world.setBlockAndMetadata(chunkX + 8, 101, chunkZ + 8, Block.pistonBase.blockID, 2);
		System.out.println("spawned at:" + (chunkX *16) + ", " + (chunkZ * 16));

	}
}

}

 

the structure is supposed to spawn over my head, and then the generator is supposed output the spawn location to the console, but for some strange reason, it won't spawn, but the message is still outputted to the console with the coords it was supposed to spawn at. Any tips?

I fixed it never-mind.
