    [1.15.2] Command identifier

    in Modder Support

    Posted

    Not sure to understand what you mean by pirated. The use case of my mod is basically any kind of private server targeting a specific community (I did it for my school MC server for example) where admins don't want to force the players (in this example students) to pay for an account. Students can register through a web API which creates their IG account, and then they can login IG.

     

    Does that still won't get any help? :/

    [1.15.2] Command identifier

    in Modder Support

    Posted · Edited by Sunser

    Hi, just wondering if there is a way to get identifiers for commands. What I mean is a way to get for example 'modid.command' for a given command. I've been looking into the sources but failed to find something helpful.

     

    I'm currently registering my commands with a CommandDispatcher and a LiteralArgumentBuilder.

     

    EDIT: My goal is the following: My mod forces players to register/login while inside the game (for people who wants to control who can play to their server). As long as a player is not logged in, he/she cannot use any other command. I'd like to allow admins to write in a config files the commands they want to whitelist (I was thinking about 'modid.command' as a format). This is how I'm listening to command calls: 

    @SubscribeEvent(priority = EventPriority.HIGHEST)
  public static void onCommand(CommandEvent event) {

     

    I'd like to know if it is possible to get a command identifier from 'CommandEvent event'.

     

    Thanks.

    [SOLVED][1.12.2] Access to another player's inventory through dimensions

    in Modder Support

    Posted · Edited by Sunser

    I'm trying to implement the well-known /invsee command. This is what I have done so far: 

        @Override
    public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
        if (args.length != 1) {
            throw new InvalidNumberOfArgumentsException();
        }
        // fetch target's inventory
        EntityPlayerMP target = server.getPlayerList().getPlayerByUsername(args[0]);
        if (target == null) return; // TODO: send an error message
        IInventory targetInventory = target.inventory;
        // displaying it to sender
        EntityPlayerMP player = (EntityPlayerMP)sender;
        player.displayGUIChest(targetInventory);
    }

     

    It works perfectly when both sender and target are in the same dimension, but if they are not, the GUI closes instantly. So I took a look at the 

    net.minecraft.entity.player.EntityPlayerMP#displayGUIChest

    source code and tried to understand why.

     

    This is the piece of code which I think blocks me: (l.948) 

          if (this.openContainer != this.inventoryContainer)
            {
                this.closeScreen();
            }

     

    I also took a look at 

    net.minecraft.entity.player.EntityPlayerMP#changeDimension

    to check if EntityPlayerMP's attributes openContainer and inventoryContainer where changed but it is not the case.

     

    What is wrong with what I am doing ? I feel like I missed something!

    [1.12.2][SOLVED] Preventing players from moving

    in Modder Support

    Posted

    I've tried adding a huge Slowness effect to some players. This works great but they can still move by jumping.

    So I've been looking for the other idea but I did not find a way to make it being called every tick.

    I've been thinking about the onUpdate() method but I haven't found how to link my method and that.

    Any suggestions ? Thanks for your time.

    The player movement happens entirely on the client, it just periodically sends packets to the server notifying it of the new position. So your options are either reset the player's position each tick on the server or cancel the input on the client.

    I was afraid I have to do this.

    Take a look at what the slowness effect does

    Someone already recommanded it in another post. I'll take a look.

     

    Thank you both. I will update the post's status as soon as I get something functional.

    Hi everyone,

     

    I'm trying to prevent unlogged players to do anything. My next challenge is to prevent players from moving, but I can't find anything that satisfies me.
     

    I've been looking into EntityPlayerMP class hierachy and I've found the SPacketPlayerPosLook class, which is sent when a player wants to move.

    I wonder if there is a way to stop it. I've been looking from a triggered Event when a packet is sent but I did not find.

     

    I've also took a look at the doc and tried to understand how things work but I did not find yet a way to achieve it.

    I wonder if an override of the 

    IMessageHandler::onMessage(SomeIMessage req, MessageContext ctx)

    method would make it.

    Any suggestions ? Thanks for your time.

    [1.10.2] Custom launcher and Forge

    Hello guys. I've meet an issue when working on a custom launcher for my private server. I know this is not a Java forum here but I think only you would be able to help me. I use this to know how the minecraft launcher starts a forge profile : 

    ps -aux | grep forge

    Detecting connection and disconnection

    in Modder Support

    Posted

    Hi all,

     

    I've been looking for way to detect when a player connect to or disconnect from a server. I was using EntityJoinWorldEvent but this is actually fired for every entity in the world, so this is not what I'm looking for. BTW, there is no EntitlyLeaveWorldEvent so I guess this is not the event I need.

    I've just discovered events like FMLNetworkEvent.ClientDisconnectionFromServerEvent which I think are fired on server side (at least for this one). My problem here is I got no way to find who has thrown this event. So I guessed that was not what I am looking for neither.

    I have to say I'm a bit lost right here. I also read a few topics here, but brought solutions are no longer available (like IPlayerTracker).

    Any idea ? Thanks in advance.

    Forge server with Docker

    Dockerfile has been edited

    Hi everyone, I'm trying to run a forge server using docker, but it doesn't work.

    - I've used the forge installer on the path of the directory I'm working in.

    - "java -jar forge.jar" is working in the console.

    - I get this error message when I'm trying to run it with docker :

    We appear to be missing one or more essential library files.

    Custom Launcher

    That might not be that hard to do, if its only a very simple launcher (I'm thinking command line script simple).

    The difficulty for me is to find the correct java command to launch it but I've not find anything working on the web.

    Quote

    You might have to deobfuscate Forge's code to see how they launch it in the Dev workspace environment.

    I guess you're right.

    I believe making your own launcher is discouraged/prohibited.

    Even the Twitch launcher still runs the official Minecraft launcher to run the game.

    Yeah I wasn't expecting something easy ahah.

    The way I understand this is that you are trying to circumvent Minecraft's login system. Correct me if I'm wrong.

     

    To answer your question - look at how forge does it. 

    something like this

    Running with arguments: [--userProperties, {}, --assetsDir, /Users/_username_/.gradle/caches/minecraft/assets, --assetIndex, 1.12, --accessToken{REDACTED}, --version, 1.12.2, --tweakClass, net.minecraftforge.fml.common.launcher.FMLTweaker, --tweakClass, net.minecraftforge.gradle.tweakers.CoremodTweaker]

     

    but you would have to look much more deeply into it.

    I'd say just create a modpack on ATL or similar.

    Also its pretty much illegal to play a game without buying it which is what your trying to do

    TL;DR

    Get everyone who's playing to buy an account

    You're wrong. We don't want people who don't have bought Minecraft. I'm using Mojang API to check it.

    I've also took a look at the forge json document in versions folder, and saw those lines, but I still get an error when I try to start the forge jar file. That is why I've made a post here ahah

    Custom Launcher

    in Modder Support

    Posted

    Hi everyone. With some friends we have been allowed to make a Minecraft server hosted by our school's server. I'm in charge of making this going well.

    As we want it modded and we often update mods we're playing with, I'm currently trying to make a custom launcher, which would directly start the good version of Minecraft. It has not as purpose to be distributed to public (only students from the school would have access to this server). The Client's code will be free when finished, to show I'm not stealing any personal data. I tried to respect every conditions of use for each mod we chose, and we use Forge 1.10.2.

    My problem is I have no idea how to run the game without opening the MC launcher first. I'd say when you press play it does something like "java -options -jar forge-name.jar args" but I didn't manage to get something working. By the way, I put MC files in the Launcher directory, I guess this would change something.

    Can anyone please help me? It would be much appreciated !

    [SOLVED][1.12.2] Override an existing entity

    in Modder Support

    Posted

    Here's the function :

    Spoiler 
    
@SubscribeEvent(priority = EventPriority.HIGHEST)
    public void replaceVanillaSnowball(EntityJoinWorldEvent event) {
        Entity entity = event.getEntity();
        World world = event.getWorld();
        if (entity instanceof EntitySnowball) {
            if (!world.isRemote) {
                // creating new entity
                EntityLivingBase thrower = ((EntitySnowball) entity).getThrower();
                EntityCustomSnowball entitysnowball = new EntityCustomSnowball(world, thrower);
                entitysnowball.shoot(thrower, thrower.rotationPitch, thrower.rotationYaw, 0.0F, 1.5F, 1.0F);
                world.spawnEntity(entitysnowball);
                // killing old entity
                world.setEntityState(entity, (byte)3);
                entity.setDead();
            }
        }
    }

    It correctly summons my custom entity but the vanilla one is still visible a few ticks.

     

    [1.12.2]Render Tutorial

    in Modder Support

    Posted

    I've just been doing this Robertusxd.

    You first need an item class which will represent in inventory the projectile. It may have 

        public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn)

    if you hand it to be thrown like a snowball. You will use the World.spawnEntity() function to summon your entity.

    Then you need an entity class which extends at least EntityThrowable.

    You may need a model but I'm not sure this is crucial.

    Finally you need a render class which extends Render<YourProjectileEntityClass> for example.

    Don't forget to register the render, the entity and the item. ;)

    Also take a look at existing classes like Arrow and Snowball ones.
