How to get only one call from slotClicked?

This is probably just me not knowing enough about Java, but I'm trying to get some custom actions to take place when the player collects the item from my crafting table.  I figure slotClicked is the method that I want to use, but the trace I have in place calls twice when I grab the item from the table.

 

 

	public ItemStack slotClick(int par1,int par2,int par3, EntityPlayer player)
{
	ItemStack r = super.slotClick(par1, par2, par3, player);
	if (par1 == 0 && r != null){
		Item crafted = r.getItem();
		if (crafted instanceof SummonerItem){
			System.out.println("Summoner Item Result");
		} 
	}
	this.onCraftMatrixChanged(this.craftingMatrix);
	return r;
}	

 

 

Is the method that I am using, and I get my trace twice.

That is because it is being run both client and server side, to make it run only once just check if(!player.worldObj.isRemote) this will make it run only on the server side

Note: I may have misspelt it so make sure you check the proper spelling

Worked like a charm, and now I know should I run into a similar problem. 

 

Thank you
