Using command arguments???

I've been searching for a while now, and it seems that noone has an effective way of using the command syntax args[#]. Can anyone explain to me how to use the arguments and define a command with more than 1 argument.
What I want to do, is create a command that enables and disables on the typing of the command. much like essentials /god on /god off .

The command;
public void chesty(CommandSender sender, Command cmd, String CommandLabel, String[] args)

I've seen it a few times, but the actual concept I haven't gotten down.

What I have so far(doesn't work at all)

Code:java

public boolean chesty(CommandSender sender, Command cmd, String commandLabel, String[] args){
if(cmd.getName().equalsIgnoreCase("chesty")){
if (!(sender instanceof Player)){
sender.sendMessage("only players may use this command");
if(chesty = false){sender.sendMessage("Please turn on chesty before using this command.");}
if(chesty = true){sender.sendMessage("Command is enabled!");
}
}

What I want to use; /chesty on && /chesty off

the code I need to implement for chesty

Code:java

@EventHandler
public void playerInteract(PlayerInteractEvent event){
Block block = event.getPlayer().getTargetBlock(null,100);
if(block.getState() instanceof InventoryHolder){
InventoryHolder ih = (InventoryHolder)block.getState();
Inventory i = ih.getInventory();
event.getPlayer().openInventory(i);

Any help will be much appreciated, thanks for you time!

 

You need to rename it.

Code:JAVA

 
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){}
 

Arguments are stored in a variable args[].
The args[0] is the command, so the args[1] would be the first argument.
So your command should look like this.

Code:JAVA

 
public boolean chesty(CommandSender sender, Command cmd, String commandLabel, String[] args){
if(cmd.getName().equalsIgnoreCase("chesty")){
if (!(sender instanceof Player)){
if(args[1].equalsIgnoreCase("on")){
chesty=true;
sender.sendMessage("You have enabled something");
return true;
}else if(args[1].equalsIgnoreCase("off")){
chesty=false;
sender.sendMessage("You have disabled something");
return true;
}else{
sender.sendMessage("Wrong command usage!");
return true;
 
}
}
}
 
 
 

 

thanks I'll be sure to try it ASAP. implementing the other source, shuold I make another class and call chesty. if it's true allow the person to use it?

 

Actually args[0] contains the first argument when using onCommand and cmd will hold the executed command. (cmd.getName() will return the name)

 

Code:java

if(args[0].equalsIgnoreCase("chesty"){

so that?

Edit: for some reason my eclipse doesn't have else if... Whenever I use it it tells me to delete the else. Any suggestions? Jdk 1.6.0.31 eclipse Java EE and classic. Neither eclipse have else if but I know most jdk's have else if.

 

This would mean that it would pick "/cmd chesty".

 

look out that "args[0]" throws an error, when the size of it (args.lenght == 0) is 0, at the case when the user dont add anny arguments
