Well...

 

I made a custom dimension staff item, that should fill the whole portal with my portal block...

It just adds one single portal block above the portal "case", not filling the whole portal

 

Here my code:

 

ItemDimensionStaff:

public class ItemDimensionStaff extends Item
{
public ItemDimensionStaff(int i)
{
	super(i);
	this.setCreativeTab(Major.obsidiaTab);
	maxStackSize = 1;
	setMaxDamage(7);
}

@Override
public boolean onItemUse(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, World par3World, int par4, int par5, int par6, int par7, float par8, float par9, float par10)
    {
	if(par1ItemStack.getItemDamage() > par1ItemStack.getMaxDamage())
	{
		--par1ItemStack.stackSize;
	}

    	 if (par7 == 0)
         {
             --par5;
         }

         if (par7 == 1)
         {
        	 ++par5;
         }

         if (par7 == 2)
         {
             --par6;
         }

         if (par7 == 3)

         }

         if (par7 == 5)
         {
             ++par4;
         }
    	
        if (par2EntityPlayer.canPlayerEdit(par4, par5, par6, par7, par1ItemStack))
        {
            int var11 = par3World.getBlockId(par4, par5, par6);

            if (var11 == 0)
            {
            	if(par3World.doesBlockHaveSolidTopSurface(par4, par5 - 1, par6))
            	{

            		if(var12 == Block.sandStone.blockID)
            		{
            			par1ItemStack.setItemDamage(par1ItemStack.getItemDamage() + 1);
            			par3World.setBlockWithNotify(par4, par5, par6, Major.ObsidiPortal.blockID);
            		}
            	}
            }
            return true;
        }
        else
        {
        	return false;
        }
    }

That's what i'm actually doing automaticly with this code:

 

for (var7 = 0; var7 < 2; ++var7)
            {
                for (var8 = 0; var8 < 3; ++var8)
                {
                    par1World.setBlockWithNotify(par2 + var5 * var7, par3 + var8, par4 + var6 * var7, Major.ObsidiPortal.blockID);
                }
            }
