Solved List plugins using command

Hello,
I am currently trying to create a plugin where when you type /auth it will display a list of plugins that are currently being used by the server. But the plugins should only show if the plugin was coded by me and if they are being used currently on the server. I've got the auth command setup but I can't figure out how to list the plugins that were coded by me and if they are active on the server.
Any help is much appreciated,
plisov

 

@plisov

1. Use PluginManager.getPlugin("NAME-OF-PLUGIN")
2. If that object is null, the plugin is not on the server
3. Else, the plugin is enabled.

 

PluginManager.getPlugin("Exo");
is turning up red. When I type just PluginManager. , it doesn't show getPlugin

 

@plisov
That is because PluginManager is not a object you can reference. You would need to get the PluginManager instance instead by getting the Server instance using getServer, and using .getPluginManager() (The same way you get the plugin manager for registering events.)

 

@plisov He means Bukkit.getPluginManager() which returns the PluginManager object and using the getPlugin method.
I wouldn't use his way. This way is much better but requires you to put yourself as the author in all your plugins.

1. Loop through all the plugins
2. Get the PluginDescriptionFile
3. Check to see if the authors contains your name

 

Would I need to put Bukkit.getServer().getPluginManager().getPlugins() into the auth command?
Also, where would I put
public final class PluginDescriptionFile extends Object {
}

Finally, I don't understand how to get the author's name from the yml

 

@plisov An enchanced for loop for the plugins

Code:

for (JavaPlugin plugin : Bukkit.getPluginManager().getPlugins()) {
   // Get plugin description file then check authors
}

JavaPlugin#getDescription(); to get the plugin description file
PluginDescriptionFile#getAuthors(); to get the authors, null check that before checking if it contains your name.

 

Are you sure it's not supposed to be

Code:

for (Plugin plugin : Bukkit.getPluginManager().getPlugins()) {
                   // Get plugin description file then check authors
                }

because otherwise Bukkit.getPluginManager().getPlugins() turns red

 

@plisov Yes, use Plugin instead of JavaPlugin, JavaPlugin is the only class that implements Plugin so it doesn't really make a difference.

 

Alright, when I type Plugin.getDescription() getDescription turns red. When I just type Plugin. all I see is .class and this

 

@plisov You need to get an instance of the Plugin object. When they say ClassName#methodName(), they mean instanceOfObject#methodName()

 

Okay, so I've managed to get everything not 'red', now I need to figure out how to display the plugins.

Code:

if (cmd.getName().equalsIgnoreCase("auth")) {
            player.sendMessage(ChatColor.RED + "-----------------------------------------------------");
            player.sendMessage(ChatColor.BLUE + "This server uses the following plugins");
          
           for (Plugin plugin : Bukkit.getPluginManager().getPlugins()) {
                plugin.getDescription().getAuthors();
            }
          
            player.sendMessage(ChatColor.RED + "-----------------------------------------------------");
        }

 

Inside your for loop, check that authors is not null, then check if it contains your name, if it does then show it with plugin.getDescription().getName();

 

Okay, thanks for that. Now I've done

Code:

        if (cmd.getName().equalsIgnoreCase("auth")) {
            player.sendMessage(ChatColor.RED + "-----------------------------------------------------");
            player.sendMessage(ChatColor.BLUE + "This server uses the following plugins ");
           
            for (Plugin plugin : Bukkit.getPluginManager().getPlugins()) {
                if(plugin.getDescription().getAuthors() == null) {
                    return false;
                } else if(plugin.getDescription().getAuthors().equals("plisov")){
                    plugin.getDescription().getName();
                }
            }
           
            player.sendMessage(ChatColor.RED + "-----------------------------------------------------");
        }

But it doesn't show the plugins in game and I can't figure out what I'm doing wrong.

 

getAuthors() returns a string list, this means it cannot equal a string, It can however contain it, use plugin.getDescription().getAuthors().contains("plisov")

 

Code:

if (cmd.getName().equalsIgnoreCase("auth")) {
            player.sendMessage(ChatColor.RED + "-----------------------------------------------------");
            player.sendMessage(ChatColor.BLUE + "This server uses the following plugins ");
          
            for (Plugin plugin : Bukkit.getPluginManager().getPlugins()) {
                if(plugin.getDescription().getAuthors() == null) {
                    return false;
                } else if(plugin.getDescription().getAuthors().contians("plisov")){
                    plugin.getDescription().getName();
                }
            }
          
            player.sendMessage(ChatColor.RED + "-----------------------------------------------------");
        }

I've tried what you suggested but still it's not showing up.

 

You need to actually show it, using Player#sendMessage(String); or Bukkit.broadcastMessage(String); right now all you're doing is getting it.

 

Well that was a stupid mistake. Wasn't thinking.

 

Don't forget to set the thread to solved if it worked

 

Yep it worked! Thanks!
