[1.7.10]Make mod server side only

[FlatronEZ]

Hello there,

 

I am new to the Forge modding community. I have been setting up and maintaining forge servers a long time, now I have started programming my own mod. My first mod is a mod that only needs to be there on the server side, because it only listens for some commands and teleports players that's it. But after successfully programming and building the mod, I can't connect to my testserver without having the mod installed on the client side.

 

So my question is: How do I make a serverside only mod? What do I need to add to my code?

 

Thanks in advance, my experience so far is that it's quiet hard to get started with Minecraft modding because getting information is not ease

Add:

acceptableRemoteVersions = "*"

 

In @Mod annotation.

Perfect!

 

Can you recommend any good site to get all the needed information to get started with mod programming? Is there any Javadoc for the never 1.7.10 Forge versions?

[Ernio]

Recommend? Welp, I've been modding since not-so-popular forge (mc beta, earlier) eveything i can recommend would be 2-3 years old.

 

Only thing I ALWAYS link are those:

All basics:

More info about MC (when updating to 1.8 look at thread-safety with packets):

EDIT

Note: There is NO "official" docs. All are small-lacking and deprecated. Forge and MC updates too often. Any questions - I'd post right here.

Perfect, will work through this

 

One final question for now: How do I check if a player has OP status? Is there any prebuild method that returns player status (I dont seek for gamemode status)?

[Ernio]

I know of 3 methods of doing it.

 

I personally use: (Player is also OP on single)

public static boolean isOp(EntityPlayer player)
{
MinecraftServer server = MinecraftServer.getServer();
if (server != null)
{
	if (server.getConfigurationManager().getOppedPlayers().getGameProfileFromName(player.getName()) != null || server.isSinglePlayer())
	{
		return true;
	}
}
return false;
}

 

BUT - this one I coded by digging in deep MC code.

People tend to use #canSendCommands() or something like that. Method is somewhere in command classes or server, idk.

I will look it up and edit this post.

 

EDIT

In ServerConfigurationManager:

public boolean canSendCommands(GameProfile profile)
    {
        return this.ops.hasEntry(profile) || this.mcServer.isSinglePlayer() && this.mcServer.worldServers[0].getWorldInfo().areCommandsAllowed() && this.mcServer.getServerOwner().equalsIgnoreCase(profile.getName()) || this.commandsAllowedForAll;
    }

For GameProfile:

player.getGameProfile()

    }

For GameProfile:

player.getGameProfile()

 

Okay thanks but this method seems to be cut out of some code. Can't get it to work right now because I don't know of what object type "this" is / what it's referencing. Something of a MinecraftServer class I guess?

You don't copy method. You use it with instance of ServConfMgr:

 

This: (check for nulls)

MinecraftServer.getServer().getConfigurationManager().canSendCommands(gameprofile)

 

Or this:

((EntityPlayerMP) player).canUseCommand() // server-side only!

 

Depending what you need - look at code. 1st one is more "internal".

[...]
	EntityPlayerMP player = (EntityPlayerMP) sender;
	player.canCommandSenderUseCommand(p_canCommandSenderUseCommand_1_, p_canCommandSenderUseCommand_2_)

	ServerConfigurationManager scm = new ServerConfigurationManager(null) {

	};
[...]

 

That's the only thing I can get. The method "canUseCommand" does not exist. Wheter for player, nor ServerConfigurationManager. I guess I am missing something out?

MinecraftServer.getServer().getConfigurationManager() - Use the search feature of your IDE to find these things.

 

Thanks, I tried but it keeps telling me that the method canSendCommands() is not defined for ServerConfigurationManager. I am using forge 1481 maybe that's the problem.

 

[...]
		EntityPlayerMP player = (EntityPlayerMP) sender;
		MinecraftServer.getServer().getConfigurationManager().canSendCommands(player.getGameProfile());
[...]

The method is called

func_152596_g

in 1.7.10.

 

That's the hint I needed! Quiet obfuscated function name How do you find such things out? Is there some kind of "command reference" ? Or did you just find it by it's parameters?

[Ernio]

Callbacks.

1. Think if there is thing you want in vanilla

2. Think of a name it would have and relations

3. Look there

4. Find by callbacks

 

To find this method you can look into e.g CommandOp.class.

 

Diesieben actually knows most of forge code, so that's a different story

[Failender]

I guess we can assume diesieben knows a lot
