  1. Wow, that worked, now the packets also arrive at the client side. Thank you for the help.
  2. There are several methods in the Item class, override one of the methods and destroy your item.
  3. I am trying to render energy in cables in my mod. The TileEntity sends a packet to the Client that says where to render the energy. But between toBytes(ByteBuf and fromBytes(ByteBuf, it causes several Exceptions and a crash. There seems to be a problem with the discriminator, it seems to be -1 when the ID of the message is 0. Here is the message registered: public static SimpleNetworkWrapper network; @EventHandler public void preInit(FMLPreInitializationEvent event){ HyperItems.load(); HyperBlocks.load(); network = NetworkRegistry.INSTANCE.newSimpleChannel("knokko Hyper Combat"); network.registerMessage(CableMessage.Handler.class, CableMessage.class, 0, Side.CLIENT); } Here is the packet class: public class CableMessage implements IMessage { public static final byte[] BYTES = new byte[]{64,32,16,8,4,2,1}; private int x; private int y; private int z; private boolean[] energy; public CableMessage() {} public CableMessage(int x, int y, int z, boolean[] energy){ this.x = x; this.y = y; this.z = z; this.energy = energy; } @Override public void fromBytes(ByteBuf buf) { System.out.println("decode from bytes..."); x = buf.getInt(0); y = buf.getInt(4); z = buf.getInt(; energy = toBinair(buf.getByte(12)); System.out.println("decoded from bytes"); } @Override public void toBytes(ByteBuf buf) { System.out.println("convert to bytes..."); buf.setInt(0, x); buf.setInt(4, y); buf.setInt(8, z); buf.setByte(12, fromBinair(new boolean[]{energy[0], energy[1], energy[2], energy[3], energy[4], energy[5], false, false})); System.out.println("converted to bytes"); } public static class Handler implements IMessageHandler<CableMessage, IMessage> { //Gets the TileEntity at the given position and marks the places to render the energy @Override public IMessage onMessage(final CableMessage message, MessageContext ctx) { IThreadListener listener = Minecraft.getMinecraft(); listener.addScheduledTask(new Runnable(){ @Override public void run(){ World world = Minecraft.getMinecraft().theWorld; TileEntity entity = world.getTileEntity(new BlockPos(message.x, message.y, message.z)); if(world.isRemote && entity instanceof TileEntityCable) ((TileEntityCable)entity).isEnergy = new boolean[]{message.energy[0], message.energy[1], message.energy[2], message.energy[3], message.energy[4], message.energy[5]}; System.out.println("packet arrived: energy = " + message.energy + " and entity = " + entity); }}); return null; } } //gets 8 booleans from 1 byte public static boolean[] toBinair(byte b){ boolean[] bools = new boolean[8]; if(b >= 0) bools[7] = true; else { b++; b *= -1; } byte t = 0; while(t < 7){ if(b >= BYTES[t]){ b -= BYTES[t]; bools[t] = true; } ++t; } return bools; } //stores 8 booleans into 1 byte public static byte fromBinair(boolean[] bools){ byte b = 0; int t = 0; while(t < 7){ if(bools[t]) b += BYTES[t]; ++t; } if(!bools[7]){ b *= -1; b--; } return b; } } Here is the method where the packet is sent: @Override public int drainEnergy(EnumFacing facing, int requestedAmount) { //isEnergy = new boolean[6]; System.out.println("drainEnergy..."); int energy = 0; //isDraining is here to prevent infinite loops if(!isDraining){ if(capacity == 0){ Block block = worldObj.getBlockState(pos).getBlock(); if(block instanceof BlockCable) capacity = ((BlockCable) block).getCapacity(); } if(requestedAmount > capacity) requestedAmount = capacity; isDraining = true; int t = 0; while(t < EnumFacing.values().length){ if(energy >= requestedAmount){ isDraining = false; //sending the packet... System.out.println("starting to send message..."); HyperCombat.network.sendToAllAround(new CableMessage(pos.getX(), pos.getY(), pos.getZ(), isEnergy), new TargetPoint(worldObj.provider.getDimensionId(), pos.getX(), pos.getY(), pos.getZ(), 32)); System.out.println("message send... hopefully"); return energy; } if(facing != EnumFacing.values()[t].getOpposite()){ int extra = drain(EnumFacing.values()[t], requestedAmount - energy); energy += extra; if(extra > 0) isEnergy[t] = true; } ++t; } } isDraining = false; if(energy > 0) isEnergy[facing.ordinal()] = true; System.out.println("starting to send message..."); HyperCombat.network.sendToAllAround(new CableMessage(pos.getX(), pos.getY(), pos.getZ(), isEnergy), new TargetPoint(worldObj.provider.getDimensionId(), pos.getX(), pos.getY(), pos.getZ(), 32)); System.out.println("message send... hopefully"); return energy; } Here is the important part of the console log: Does anybody understand what goes wrong here? Why is the discriminator -1?
  4. This code works for me in 1.7.10, maybe it will work too in 1.8: @Override public boolean doesContainerItemLeaveCraftingGrid(ItemStack itemStack) { return false; }
  5. Copy your source code, install forge, and paste your source code there. And than you can start fixing a few hundred errors probably
  6. Read your code very carefully, you probably forgot a ';' or bracket'('.
  7. As potioneffect, you can use new PotionEffect(7, 1, 100);
  8. Here is the superclass: public abstract class Dragon extends EntityFlying implements IMob{ protected EntityLivingBase target; public Dragon(World worldIn) { super(worldIn); setSize(30, 3); isImmuneToFire = true; } public void onUpdate(){ super.onUpdate(); if(target == null){ target = worldObj.getClosestPlayerToEntity(this, getEntityAttribute(SharedMonsterAttributes.followRange).getAttributeValue()); } if(target != null){ followTarget(); shootingUpdate(); faceEntity(target, 30, 30); } attackEntities(); } public abstract void shootingUpdate(); public void attackEntities(){ AxisAlignedBB aabb = getEntityBoundingBox(); List list = worldObj.getEntitiesWithinAABBExcludingEntity(this, aabb); int times = 0; while(times < list.size()){ Entity entity = (Entity) list.get(times); if(!(entity instanceof EntityItem)){ entity.attackEntityFrom(DamageSource.causeMobDamage(this), (float) getEntityAttribute(SharedMonsterAttributes.attackDamage).getAttributeValue()); } ++times; } } public void followTarget(){ Line line = new Line(new Position(this), new Position(target)); double speed = getEntityAttribute(SharedMonsterAttributes.movementSpeed).getAttributeValue(); motionX = ExtraUtils.divineAccurate(line.distanceXT, line.distance) * speed; motionY = ExtraUtils.divineAccurate(line.distanceYT, line.distance) * speed; motionZ = ExtraUtils.divineAccurate(line.distanceZT, line.distance) * speed; } public void setAttackTarget(EntityLivingBase entity){ target = entity; } public void setRevengeTarget(EntityLivingBase entity){ target = entity; } public EntityLivingBase getAttackTarget(){ return target; } public EntityLivingBase getAITarget(){ return target; } public void applyEntityAttributes(){ super.applyEntityAttributes(); getAttributeMap().registerAttribute(SharedMonsterAttributes.attackDamage); } public AxisAlignedBB getCollisionBox(Entity in){ return getEntityBoundingBox(); } public AxisAlignedBB getBoundingBox(){ return getEntityBoundingBox(); } } Here is the 'real' class: public class FireDragon extends Dragon{ public int cooldown; public int fireTimer; public boolean shootCooldown; public FireDragon(World worldIn) { super(worldIn); setSize(30,3); } @Override public void shootingUpdate() { if(!worldObj.isRemote){ if(cooldown <= 0){ if(fireTimer < 5 && shootCooldown){ EntityLargeFireball fire = new EntityLargeFireball(worldObj, this, 1, 1, 1); fire.explosionPower = 2; worldObj.spawnEntityInWorld(fire); ++fireTimer; shootCooldown = false; } else if(fireTimer >= 5){ cooldown = 100; fireTimer = 0; } else { shootCooldown = true; } } else { --cooldown; } } } @Override public void applyEntityAttributes(){ super.applyEntityAttributes(); getEntityAttribute(SharedMonsterAttributes.attackDamage).setBaseValue(10); getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(0.3); getEntityAttribute(SharedMonsterAttributes.followRange).setBaseValue(64); getEntityAttribute(SharedMonsterAttributes.maxHealth).setBaseValue(400); } } Any ideas what can go wrong?
  9. Are you sure you have exported all required folders? You needed to export 3 folders. Can you open the source folders from the mod that imports the other mod?
  10. I have tested it's hitbar with arrows. The hitbar for arrows is different than the hitbar for normal attacks. Really strange, isn't it?
  11. I have looked in EntityZombie and EntityDragon (of minecraft) and there block size is used. Can it be a problem with max lenght or something?
  12. I think like the normal blocks, but they have a lot of subblocks.(metadata, data values...)
  13. It isn't as difficult as you think. It was pretty easy for me, even when I hardly knew java. Eclipse has an export option, you need to export src/main/java, src/main/resources and the folder src. In eclipse you have a toolbar above your files, you need project/properties/libraries/add external jar and than choose the jar you created with the export funtion.
  14. I allready have that, "setSize(30,3)". The hitbar is still very small. But the hitbar isn't large enough.
  15. I think bFull3D was the return his IDE used to auto-complete his method I think he is a beginnen because he didn't find his problem himself and what diesieben said.
  16. remove "--stack.stackSize", this means that your stacksize will reduce. And your item will disappear if you are not more carrying than one.
  17. I am having a problem with my dragon. It is a very large model with a lenght of 30 blocks, but it has the hitbar of a "tiny" player. And the attack reach of the dragon is as large as it's body, so the player can't hit it before the dragon hits the player. Is there a way to give it a larger hitbar?
  18. Why are you making a custom potion effect? You can just use /effect player 7 1 100 to give somebody a good strike. Or in code : entity.setDead()
  19. For a random amount of damage: Random random = new Random(); 25 + random.nextInt(16); will give a number between 25 and 45
  20. Override this method in Item to update your item every tick. Now create a simple field and edit it every tick. public void onUpdate(ItemStack item, World world, Entity entity, int a, boolean b)
  21. This is a bug of minecraftforge, it happens to me a lot to.
  22. What do you want with this topic? And a tip: player.addChatMessage(new ChatComponentTranslation(EnumCharFormatting.RED + "This message will be red!"));
  23. This helps understanding it. So I can't help it really and I just have to wait for minecraft forge to solve this?
  24. I have allready readed what it is. But I didn't understand it completely, I think it means that an important collection is modified. But anyway: I believe I will have to wait until minecraft forge solve this problem and just do something else until than. I don't think I can do anything.
  25. I thought the render should fail the current tick, and it would go better the tick after it. In that case, ignoring would be better than crashing. But if the problem is not going to solve itself... Than this will be a big problem.
