hi! as you may have seen  @ my other thread :http://www.minecraftforge.net/forum/index.php/topic,6282.0.html

i have created code for a block to place on punch.

here is my block:

 

package tuskiomi.common;

import org.lwjgl.Sys;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.world.World;

public class TGrayCobble extends Block{
protected static final int BIDR = 3821;
public TGrayCobble(int par1) {
  super(par1, Material.rock);
  setTextureFile("/tuskiomi/painted blocks.png");
  setHardness(5.0F); 
  setResistance(7.0F);
  setBlockName("Gray Cobble");
  setCreativeTab(CreativeTabs.tabAllSearch);

}
    public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9)
    {
        return false;
    }
    public void onBlockClicked(World par1World, int par2, int par3, int par4, EntityPlayer p5EP) {
     if(p5EP.inventory.getCurrentItem().itemID == 1 && p5EP.inventory.getCurrentItem().itemID != 0 && p5EP != null && par2 * par3 != 0 && par2 * par4 != 0){
      par1World.setBlock(par2, par3, par4, 4);
      
      }
     System.out.println("debug tick.");
    }
    public int getBlockTextureFromSide(int par1)
    {
        return 116;//same texture for all sides
    }


}

seems like you have a NPE in your mod, doesn't seem like this has anything to do with forge.

gotcha, locking now
