How to register commands and where is the class, that register vanilla commands in ServerCommandManager, and I should register them in init or preinit?

You might find this usefull.

You should register them during FMLServerStartingEvent. Example:

 

public class MyMainModClass {

 

    // Additional code ...

 

    @EventHandler

    public void serverStarting(FMLServerStartingEvent event) {

        event.registerServerCommand(new MyCustomCommand()); // MyCustomCommand must inherit the CommandBase class

    }

}

I think it's still for 1.6.4, but Mekanism (an open-source mod on GitHub) has all the relevant methods to make this work.

MrArcane111, I followed this http://www.minecraftforge.net/wiki/Server_Command and it worked perfectly fine for me, and I am using 1.7.2.

 

I don't see what else to discuss here even, follow the tutorial, the end.

But since I am in good mood,  I will share my sample command code with you.

package com.zetaworx.proboblyawesome.handler;

import java.util.ArrayList;
import java.util.List;

import net.minecraft.command.ICommand;
import net.minecraft.command.ICommandSender;
import net.minecraft.util.ChatComponentText;

public class CommandHandle implements ICommand
{
private List<String> aliases;
public CommandHandle()
{
	this.aliases = new ArrayList<String>();
	this.aliases.add("probobly");
	this.aliases.add("awesome");
	this.aliases.add("proboblyawesome");
}

@Override
public String getCommandName()
{
	return "pa";
}

@Override
public String getCommandUsage(ICommandSender icommandsender)
{
	return "pa <text/help>";
}

@Override
public List<String> getCommandAliases()
{
	return this.aliases;
}

@Override
public void processCommand(ICommandSender icommandsender, String[] astring)
{
	if(astring.length == 0)
	{
		icommandsender.addChatMessage(new ChatComponentText("Invalid Arguments. Usage: " + this.getCommandUsage(icommandsender)));
		return;
	}
	if (astring[0] == "help")
	{
		icommandsender.addChatMessage(new ChatComponentText("Usage: " + this.getCommandUsage(icommandsender)));
		return;
	} else {
	ChatComponentText msg = new ChatComponentText("Output: [");
	for (int i = 0;i < astring.length; ++i)
	{
		msg.appendText(" " + astring[i]);
	}
	msg.appendText(" ]");
	icommandsender.addChatMessage(msg);	
	}
}

@Override
public boolean canCommandSenderUseCommand(ICommandSender icommandsender)
{
return true;
}

@Override
public List<?> addTabCompletionOptions(ICommandSender icommandsender,
String[] astring)
{
return null;
}

@Override
public boolean isUsernameIndex(String[] astring, int i)
{
return false;
}

@Override
public int compareTo(Object o)
{
return 0;
}
}

 

and this in your mod file

    @EventHandler
    public void serverLoad(FMLServerStartingEvent event)
    {
    	event.registerServerCommand(new CommandHandle());
    }

 

my command is using ICommand interface which is what CommandBase is extending from, but for time being I didn't need CommandBase functions so I didn't use it.

 

Ps. my command also shows how to send user a chat message.
