Solved GameMode Creative not working?

Ok so I'm making this /Admin Plugin where basically when you perform the command it puts you in creative mode and invisibility mode but I cant seem to get the GameMode statement to work here is my code and yes I have the import

Code:

if(cmd.getName().equalsIgnoreCase("admin")) {
                    Player p = (Player)sender;
                    if(!admin.contains(p));
                        for (Player pl : Bukkit.getServer().getOnlinePlayers()) {
                            pl.hidePlayer(p);
                        }
                        admin.add(p);
                        p.setGameMode(GAMEMODE.CREATIVE);

 

For setting armor, you have to get the PlayerInventory and then use the following methods to set armor contents.
setLeggings(ItemStack leggings)
setHelmet(ItemStack helmet)
setChestplate(ItemStack chestplate)
setBoots(ItemStack boots)

 

ahh thanks man, know anything about the getting time of the cooldown?

 

@Jayyy There's two ways.

1. Add to a HashMap the UUID and System time with there cooldown time
or
2. Add to a list and remove in a scheduled task

Then check times or check if they're in the list when they do the command

 

Any suggestions as to what I could replace it with? *Also there is this thing I've been having "trouble" with its really bothering me http://prntscr.com/83b6u6 how would I get rid of the listing of the command after I perform the command, for instance

/cc *clearschat*
/cc *<-----------* that shows up after i perform the command, It really bothers me and I can't figure it out

 

Put a return true; at the end of the command in your code

 

THANK YOU LOL

 

Haha no problem, I think I asked that exact question a few months ago when I was starting out

 

Actually the problem is the "Bukkit.getPlayer()" statement it draws a line through the statement, So I was wondering what other statement I would input to replace it? Thanks

 

If something is depreciated then it should still work. Crossed out with some sort of yellow underline or lightbulb? That's fine. If it has a red underline or red X then it isn't.

 

Thanks I'm just fairly new learning alot lately from the bukkit community glad to have everyone here helping me become better
