Solved Please tell me how to Hide Plugin!!

I use a rental server. So, I can watch only a thing like a while ago...
Perhaps, I may get a wrong meaning of log.

Is that right?

 

The commands are usable, but files are not generated.

 

Sorry, thank you until now.

 

Which file? The config file? I think you need to run createConfig() if it does not exist.

 

It does: org.bukkit.plugin.Plugin#saveConfig

 

But it creates a config if it does not exist.

 

You dont need to create a method to create a config, maybe a method to save and load the config..

 

I'll assume the reason why you get errors when running the command is because the section you are trying to get string from is null and the configuration file itself is not present.

If you manually made a config.yml in your source, you can get it by writing this on your onEnable()

Code:

getConfig().options().copyDefaults(true);
saveConfig();

or

Code:

saveDefaultConfig();

That case the plugin will load the config.yml

And I noticed a thing. In,

Code:

for (Player allplayer : getServer().getOnlinePlayers()) {
    if (!allplayer.isOp()) {
        player.hidePlayer(allplayer);
    }
}

This actually hides all the online players except OPs from the sender. Are you sure this is what you are trying to achieve? If not, try reversing it. allplayer.hidePlayer(player); this will hide the sender from all players except OPs.

 

Could you tell me more?

Thank you very much!!
Those problems were all resolved.
By the way,

Code:

for (Player allplayer : getServer().getOnlinePlayers()) {
    if (!allplayer.isOp()) {
        player.hidePlayer(allplayer);
    }
}

It is all right as it is here.
