[1.7.2] Packets Help Byte-Int[UNSOLVED]

Posted April 25, 201411 yr

Hello everyone im trying to update my AI Packets for my mod however since Packets now use bytes often im having issues with my sendingPackets it often crashes here

public class Packet02 extends AbstractPacket{

private byte animID;
private int entityID;

public Packet02(int id, EntityMob mob) {
	animID = (byte) id;
	entityID = tigrex.getEntityId();
}

@Override
public void encodeInto(ChannelHandlerContext paramChannelHandlerContext, ByteBuf x) {
	x.writeByte(animID);
	x.writeInt(entityID);
}

@Override
public void decodeFrom(ChannelHandlerContext paramChannelHandlerContext, ByteBuf x) {
	animID = x.readByte();
	entityID = x.readInt();
}

@Override
public void handleClientSide(EntityPlayer paramEntityPlayer) {
	EntityMob mob= (EntityMob)paramEntityPlayer.worldObj.getEntityByID(entityID);
	if(mob != null && animID != -1) {
		mob.setAnimID(animID);
		if(animID == 0) mob.setAnimTick(0);
	}
}

@Override
public void handleServerSide(EntityPlayer paramEntityPlayer) {

}

}

specifically this line which causes the crash

x.writeByte(animID);

also this is the entity code that sends the packet to its AI

public void sendAttackPacket(int id){
        if(ModMain.isEffectiveClient())
        {
            return;
        }
        currentAttackID = id;
        MHFCMain.pipe.sendToAll(new Packet02(id, this));
      
    }

Are you sure you can cast your currentAttackId to a byte without overflowing the stack? If your id is an int with a possible value greater than 255, then you should leave it as an int. ByteBuf can write integers just as well as bytes, as you did with the entityId.

Why you ignore the argument that is the mob and use a hardcoded entity instance?

public Packet02(int id, EntityMob mob) {
	animID = (byte) id;
	entityID = tigrex.getEntityId();
}

In other words, "tigrex" is not an argument to the Packet02 constructor, so where's it from? What's wrong with the argument "mob"?

If the error is on this line, I imagine it is a "Null Pointer Exception", yes?

		x.writeByte(animID);

That probably means you are calling

	@Override
public void encodeInto(ChannelHandlerContext paramChannelHandlerContext, ByteBuf x) {
	x.writeByte(animID);
	x.writeInt(entityID);
}

with an argument x that is null.

If you can figure out why that is happening, you'll be a step closer...

bump any help ? need to fix this tonight please someone help

You need to have a standard constructor without parameters, like

public Packet02Tigrex() {...}

It happened to me, too.

The constructor can be completely empty.

can you give us the new packet code and possibly your pipeline class (the type class of MHFCMain.pipe)?

Did you register your packet in the PacketPipeline?

public void initialise() {
this.channels = NetworkRegistry.INSTANCE.newChannel(ModInfo.CHANNEL, this);
registerPacket(YourPacket.class);
// register all packets here
}

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Dealing with modded server issues can be a real headache been there! At least you can keep your look stress-free with a fresh low taper fade.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
