Solved Args problem

I am trying to make a command that is like "/cg -6" but when I try to command I keep getting a error, and I have made a few others that just done something else.

Code:

Code:

if(args[0].equalsIgnoreCase("-6")){
                    if(!(p.hasPermission("customgravity.-6"))){
                        mm.getInstance().severe(p, "You do not have permission!");
                        return true;
                    }
                    p.removePotionEffect(PotionEffectType.SPEED);
                    p.removePotionEffect(PotionEffectType.JUMP);
                    p.removePotionEffect(PotionEffectType.SLOW);
                    p.setFlying(true);
                    mm.getInstance().good(p, "Gravity set to -6");
                    cooldown.add(p);
                    Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable(){
                        public void run(){
                            cooldown.remove(p);
                        }
                    }, 5);
                    return true;
                }

Error:

Read the stack trace. It says in plain English what is causing the issue.

 

Oh, did not watch it before, but how can I give a player fly?

 

For it to not be false, you need to set it to true.

 

So this is the right way to do it?

Code:

p.setAllowFlight(true);
                    p.setFlying(true);

 

Correct.

 

amhokies Ok thanks for the help
