Furnace Code Help

Hey, I 'm developing mod for with the furnace. After the
"Furnace = (new BlockFurnace(64, false)).setHardness............."
What does the false part mean? Thanks. Sorry if this seems like a noobish question or if i posted in the wrong place.

anyone know where to find this information?

Can you post more of the code with what you are trying to do?

The false in Java also usually refers to the String/Object being not as it is, eg (normal commnd set-out with Bukkit)

Code:java

 
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] arg) {
if (commandLabel.equalsIgnoreCase("command")) {
if (sender instanceof Player == false) {
/* If the sender is not a player, then continue with the code (as it equals false), if sender is player,
stop here (as it is true) */
return true;
 

Hope this makes sense.

 

This could be a swing and a miss, but the false could mean that the furnace is not in the on state?
