[1.7.10]cant figure out packets


mrgreaper

Recommended Posts

Ok so im trying to get back into modding and to get something done i never managed before...packets

i spent a fair while following some well made guides but nothing went right....turns out they were out of date lol

so i searched more and i see "simple network wrapper" is the way to go, and i thought i had it sorted....untill i tried to use them

 

 

in my main mod file i have

public static SimpleNetworkWrapper network;

..snip..

    @Mod.EventHandler
    public void preInit(FMLPreInitializationEvent event) {
        configHandler.init(event.getSuggestedConfigurationFile());
        network = NetworkRegistry.INSTANCE.newSimpleChannel("messengerBunny"); //so we create the channel
        //here is where we add the pacets...registering one packet per class
        network.registerMessage(speechPacket.speechPacketHandler.class,speechPacket.class,0, Side.CLIENT);//so we are registering a packet called speechpacket to channel one of our network (the messenger bunny) hmmm ok can understand that
        permissions.init();//lets give the artists thier well deserved credit!
        creativeTabs.init();//set up the creative tabs
        blocks.init(); //lets load our blocks
        if (configHandler.RecordsEnabled){
            records.init();} //load the records
        if (configHandler.BunnysEnabled){
            bunnys.init();} // if bunnys are enabled we load them (this modular stuff is gonna kill me lol)
        FMLCommonHandler.instance().bus().register(new eventHandler());// load the event handlers
        MinecraftForge.EVENT_BUS.register(new eventHandler());
    }

..snip..

 

then my packet is

 

package com.mrgreaper.themrgmod.network;

import com.mrgreaper.themrgmod.themrgmod;
import cpw.mods.fml.common.network.ByteBufUtils;
import cpw.mods.fml.common.network.simpleimpl.IMessage;
import cpw.mods.fml.common.network.simpleimpl.IMessageHandler;
import cpw.mods.fml.common.network.simpleimpl.MessageContext;
import io.netty.buffer.ByteBuf;
import net.minecraft.nbt.NBTTagCompound;

/**

public class speechPacket implements IMessage {
    private String message;
    private double voice;
    private float pitch;
    private float pitchRange;
    private float pitchShift;
    //private String voiceName;

    public speechPacket(){} //without this blank one the packet crashes ...why do we need it? arghhhhhhhhhh



    public speechPacket(String message,double voice,float pitch, float pitchRange, float pitchShift ){
        this.message=message;
        this.voice=voice;
        this.pitchRange = pitchRange;
        this.pitch = pitch;
        this.pitchShift= pitchShift;
    }

    @Override
    public void fromBytes(ByteBuf buf) { // so we will need an nbt tag to store the info we want to send...here we read it
        NBTTagCompound tag = ByteBufUtils.readTag(buf);
        message = tag.getString("message");
        voice = tag.getDouble("voice");
        pitch = tag.getFloat("pitch");
        pitchRange = tag.getFloat("pitchRange");
        pitchShift = tag.getFloat("pitchShift");

    }

    @Override
    public void toBytes(ByteBuf buf) { //and here we create it
        NBTTagCompound tag = new NBTTagCompound();
        tag.setString("message",message);
        tag.setDouble("voice",voice);
        tag.setFloat("pitch",pitch);
        tag.setFloat("pitchRange",pitchRange);
        tag.setFloat("pitchShift",pitchShift);
    }

    public static class speechPacketHandler implements IMessageHandler <speechPacket,IMessage> { //so dont lile classes inside classes but everything i read suggests this is the way to go...still grrrrrr
        @Override
        public IMessage onMessage(speechPacket message, MessageContext ctx) {
            themrgmod.proxy.speechCreate(message.message,message.voice,message.pitch,message.pitchRange,message.pitchShift);
            return null;
        }
    }
}

 

that has the handler class inside it too

 

now its called from my eventhandler (as a test)

 package com.mrgreaper.themrgmod.lib;

import com.mrgreaper.themrgmod.network.speechPacket;
import com.mrgreaper.themrgmod.themrgmod;
import cpw.mods.fml.client.event.ConfigChangedEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.PlayerEvent;

/**
* Created by david on 11/01/2015.
*/
public class eventHandler {


    @SubscribeEvent
    public void onConfigurationChangeEvent(ConfigChangedEvent.OnConfigChangedEvent event) {
        if (event.modID.equalsIgnoreCase(constants.modid)) {
            configHandler.loadConfiguration();
        }
    }



    @SubscribeEvent//test event
    public void TwistedPickupEvent(PlayerEvent.ItemPickupEvent event) {
        logHelper.info("if i can read this then the event handler is working" + event.pickedUp);
        themrgmod.network.sendToAll(new speechPacket("hello i think im working",12,23,12,3));


    }
}

 

first a note on sendToAll.... i tried sentToAllAround as that seems perfect for the end goal....but it wanted a target point and nothing i tried to use as the target was valid including event.player.getPlayerCoordinates() which would be the specific co-ords to use but it wasnt having it

event.player was also not valid for send to specific player. O.o

 

anyway the above results in this when you pickup an item

I did have an unknown function error before i added the blank method call (as advised to someone with the same issue i had)

 

also i realise i have a redundent step, the packet is sent to the client side so i dont really need to use the proxy (that makes sure the code is only run on the client side) but i cant see that hurting it (unless im wrong).

You never write the NBT tag to the byte buffer, so the buffer index goes out of bounds when you try to read values from it.

 

As for the nested handler class, it is simply convenient because you can then access the message class' private members without adding getter methods, and your handler is 99.9999999999999999999% likely to never be used in isolation anyways.

Check out diesieben07's tutorial on packets.

 

The reply is appreciated but i  have read that a few times, thats how im as far as i am (it seemed the only uptodate one i could find and was referenced in a lot of other places)

 

That doesnt help the issue though

 

registering the packet....yep its registered

implementing the packet class ...yep thats done

implementing the packet handler...yep done (even did it inside the other class as shown, though i dont like having classes inside classes as thats new to me)

sending packets.... done...but not working

packet responses...not needed a response so havent done that, but it looks self explanatory

ah! ok now its working! thank you

 

i still dont get targetpoints though.

 

Lets take an example of what i want to do,

 

a tile entity will emit the speech synth and all with in a range of x will hear it.. now how i would do that on 1.6.4 is to use the code from the beacon to get all the players in a box and then play a sound at them (or in this case send a packet to them, 1 by 1 just going through the list of players in that range), the sendToAllAround seems like a god send, but i just dont know how to make it use the tile entitiy (or any entitiy/co-ords) as the main point...or how to tell it the range

You're sending the packet from your TileEntity, right? So you should have x/y/zCoord available to create the TargetPoint:

// for example, to send to all within 64 blocks:
yourNetworkInstance.sendToAllAround(message, new NetworkRegistry.TargetPoint(dimension, xCoord, yCoord, zCoord, 64.0D));

 

ah i see, for some reason i thought it took only one value....hence my confusion. seems rather simple now lol

 

thank you.

    • Hello. I've been having a problem when launching minecraft forge. It just doesn't open the game, and leaves me with this "(exit code 1)" error. Both regular and optifine versions of minecraft launch just fine, tried both with 1.18.2 and 1.20.1. I can assure that my drivers are updated so that can't be it, and i've tried using Java 17, 18 and 21 to no avail. Even with no mods installed, the thing won't launch. I'll leave the log here, although it's in spanish: https://jmp.sh/s/FPqGBSi30fzKJDt2M1gc My specs are this: Ryzen 3 4100 || Radeon R9 280x || 16gb ram || Windows 10 I'd appreciate any help, thank you in advance.
    • Hey, Me and my friends decided to start up a Server with "a few" mods, the last few days everything went well we used all the items we wanted. Now our Game crashes the moment we touch a Lava Bucket inside our Inventory. It just instantly closes and gives me an "Alc Cleanup"  Crash screen (Using GDLauncher). I honestly dont have a clue how to resolve this error. If anyone could help id really appreciate it, I speak German and Englisch so you can choose whatever you speak more fluently. Thanks in Advance. Plus I dont know how to link my Crash Report help for that would be nice too whoops
    • I hosted a minecraft server and I modded it, and there is always an error on the console which closes the server. If someone knows how to repair it, it would be amazing. Thank you.
