How do I broadcast a message to everyone on the server? If there isn't already functionality for that (though I imagine there is... somewhere), how would I get a list of all online players?

 

And, how do you determine if a player is opped? I saw something in CommandBase about command permission level. Not sure if that's involved in this, but I have no idea where to find that information. x.x

 

Also, as I am learning the api, I seem to have a lot of questions that seem trivial. I search through the code and checked the javadocs and still can't find answers a lot of the time. I hate resorting to ask a question as simple as this on the forum... what are other resources?

 

kthx.

everything your looking for should be in the ServerConfigurationManager

 

to for example see if a player can use a command from a standard Player instance:

(EntityPlayerMP) playerVar..mcServer.getConfigurationManager().areCommandsAllowed(this.username);

 

this will ( on the server side ) cast player to the server sides multiplayer instance , get the server instance and then the configuration manager where it would return whether or not that player ( or any player with that name ) could use commands ( opped level ones, /me or /tell arnt included in that check )

Alright, thanks. But say I need to determine if they're op for a non-command related thing, this is what I came up with... I think it'll work?

 

public class Util
{
public static boolean isOp(ICommandSender sender)
{
	return MinecraftServer.getServer().getConfigurationManager().getOps().contains(sender.getCommandSenderName());
}

public static EntityPlayerMP getPlayerExact(String username)
{
	return username == null ? null : MinecraftServer.getServer().getConfigurationManager().getPlayerForUsername(username);
}

public static EntityPlayerMP getPlayerBestMatch(String username)
{
	String bestMatch = null;
	for(String name : MinecraftServer.getServer().getAllUsernames())
	{
		if(name.equalsIgnoreCase(username))
		{
			bestMatch = name;
			break;
		}
		else
		{
			if(name.toLowerCase().startsWith(username.toLowerCase()))
			{
				bestMatch = name;
			}
		}
	}
	return getPlayerExact(bestMatch);
}

public static void broadcastMessage(String message)
{
	for(String name : MinecraftServer.getServer().getAllUsernames())
	{
		getPlayerExact(name).sendChatToPlayer(message);
	}
}

public static void sendInfo(ICommandSender sender, String message)
{
	sender.sendChatToPlayer(ChatFormat.YELLOW + message);
}

public static void sendError(ICommandSender sender, String message)
{
	sender.sendChatToPlayer(ChatFormat.RED + message);
}
}

 

Gonna test it out in a bit. But, yeah.
