Lambda

How would I get two of the TEs from the list and compare them, thats my question

Yes I know that, I need to be able to grab another te and check their blockpos

How would I get another instance of a te to compare it to?

Is there anyway to access the player?

How would I get an instance of the server? I need to be able to access their capability.

Hey there, I'm trying to sync a value when the player joins the game, however, using EntityJoinedWorldEvent seems to cause this on join: // Why did you do that?

No I fixed it, the Item i was using to change the mana wasn't check !worldObj.isremote , Its working perfect now! Thanks!

Okay doing this: PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), (EntityPlayerMP) this.getEntity()); seems to crash with this: java.lang.ClassCastException: net.minecraft.client.entity.EntityPlayerSP cannot be cast to net.minecraft.entity.player.EntityPlayerMP

Okay, what should I use for the player arg? I tried: public class CapabilityManaData extends ManaHandler { private EntityLivingBase entity; private EntityPlayerMP entityPlayerMP; public CapabilityManaData(){ super(500000); } public CapabilityManaData(int capacity, int maxReceive, int maxExtract){ super(capacity, maxReceive, maxExtract); } public EntityLivingBase getEntity() { return entity; } public void setEntity(EntityLivingBase entity) { this.entity = entity; } public int extractManaInternal(int maxExtract, boolean simulate){ int before = this.maxExtract; this.maxExtract = Integer.MAX_VALUE; int toReturn = this.extractMana(maxExtract, simulate); PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()),entityPlayerMP); this.maxExtract = before; return toReturn; } public int receiveManaInternal(int maxReceive, boolean simulate){ int before = this.maxReceive; this.maxReceive = Integer.MAX_VALUE; int toReturn = this.receiveMana(maxReceive, simulate); PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), entityPlayerMP); this.maxReceive = before; return toReturn; } @Override public int receiveMana(int maxReceive, boolean simulate){ if(!this.canReceive()){ return 0; } int mana = this.getManaStored(); int manaReceived = Math.min(this.capacity-mana, Math.min(this.maxReceive, maxReceive)); if(!simulate){ this.setManaStored(mana+manaReceived); } PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), entityPlayerMP); return manaReceived; } @Override public int extractMana(int maxExtract, boolean simulate){ if(!this.canExtract()){ return 0; } int mana = this.getManaStored(); int manaExtracted = Math.min(mana, Math.min(this.maxExtract, maxExtract)); if(!simulate){ this.setManaStored(mana-manaExtracted); } PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(this.getManaStored()), entityPlayerMP); return manaExtracted; } public void readFromNBT(NBTTagCompound

this.getManaStored()); } public void setManaStored(int energy){ this.mana = energy; } } creating a variable, but obviously that crashed with: 01:09:27] [Client thread/ERROR]: FMLIndexedMessageCodec

So what method would I use for sending it to client? sentTo ?

Incompatible types.

Actually, futher debugging shows that it isnt even called, @Override public IMessage onMessage(ManaNetworkSyncClient message, MessageContext ctx) { IThreadListener mainThread = Minecraft.getMinecraft(); mainThread.addScheduledTask(new Runnable() { @Override public void run() { System.out.println("okay its running"); //NEITHER IS THIS if(Minecraft.getMinecraft().thePlayer.hasCapability(CapabilityMagic.MANA, null)) { System.out.println("YES"); //ISNT BENING CALLED CapabilityManaData cap = Minecraft.getMinecraft().thePlayer.getCapability(CapabilityMagic.MANA, null); cap.setManaStored(message.mana); } System.out.println(String.format("Received %s from %s", message.mana, ctx.getServerHandler().playerEntity.getDisplayName())); } }); return null; // no response in this case } both system.out are not being called, so I'm guess something is wrong. I am registering my packet, maybe something with sending my packets?

Okay: Where I'm sending packets: public class CapabilityManaData extends ManaHandler { private EntityLivingBase entity; public CapabilityManaData(){ super(500000); } public CapabilityManaData(int capacity, int maxReceive, int maxExtract){ super(capacity, maxReceive, maxExtract); } public EntityLivingBase getEntity() { return entity; } public void setEntity(EntityLivingBase entity) { this.entity = entity; } public int extractManaInternal(int maxExtract, boolean simulate){ int before = this.maxExtract; this.maxExtract = Integer.MAX_VALUE; int toReturn = this.extractMana(maxExtract, simulate); PlentifulMisc.network.sendToServer(new ManaNetworkSyncClient(this.getManaStored())); this.maxExtract = before; return toReturn; } public int receiveManaInternal(int maxReceive, boolean simulate){ int before = this.maxReceive; this.maxReceive = Integer.MAX_VALUE; int toReturn = this.receiveMana(maxReceive, simulate); PlentifulMisc.network.sendToServer(new ManaNetworkSyncClient(this.getManaStored())); this.maxReceive = before; return toReturn; } @Override public int receiveMana(int maxReceive, boolean simulate){ if(!this.canReceive()){ return 0; } int mana = this.getManaStored(); int manaReceived = Math.min(this.capacity-mana, Math.min(this.maxReceive, maxReceive)); if(!simulate){ this.setManaStored(mana+manaReceived); } PlentifulMisc.network.sendToServer(new ManaNetworkSyncClient(this.getManaStored())); return manaReceived; } @Override public int extractMana(int maxExtract, boolean simulate){ if(!this.canExtract()){ return 0; } int mana = this.getManaStored(); int manaExtracted = Math.min(mana, Math.min(this.maxExtract, maxExtract)); if(!simulate){ this.setManaStored(mana-manaExtracted); } PlentifulMisc.network.sendToServer(new ManaNetworkSyncClient(this.getManaStored())); return manaExtracted; } public void readFromNBT(NBTTagCompound compound){ this.setManaStored(compound.getInteger("Mana")); } public NBTBase writeData() { NBTTagCompound tag = new NBTTagCompound(); tag.setInteger("Mana", mana); return tag; } public void readData(NBTBase nbt) { NBTTagCompound tag = (NBTTagCompound) nbt; this.setManaStored(tag.getInteger("Mana")); } public void writeToNBT(NBTTagCompound compound){ compound.setInteger("Mana", this.getManaStored()); } public void setManaStored(int energy){ this.mana = energy; } } -So everytime extract/receive mana is called, it will update. Handler: public class ManaNetworkHandler implements IMessageHandler<ManaNetworkSyncClient, IMessage> { public ManaNetworkHandler(){} @Override public IMessage onMessage(ManaNetworkSyncClient message, MessageContext ctx) { IThreadListener mainThread = Minecraft.getMinecraft(); mainThread.addScheduledTask(new Runnable() { @Override public void run() { if(Minecraft.getMinecraft().thePlayer.hasCapability(CapabilityMagic.MANA, null)) { CapabilityManaData cap = Minecraft.getMinecraft().thePlayer.getCapability(CapabilityMagic.MANA, null); cap.setManaStored(message.mana); } System.out.println(String.format("Received %s from %s", message.mana, ctx.getServerHandler().playerEntity.getDisplayName())); } }); return null; // no response in this case } } Network: public class ManaNetworkSyncClient implements IMessage { public int mana; public ManaNetworkSyncClient(){} public ManaNetworkSyncClient(int toSend) { this.mana = toSend; } @Override public void toBytes(ByteBuf buf) { // Writes the int into the buf buf.writeInt(mana); } @Override public void fromBytes(ByteBuf buf) { // Reads the int back from the buf. Note that if you have multiple values, you must read in the same order you wrote. mana = buf.readInt(); } }

Did that but, still no luck I'm trying to sync a cap between the client and server, however, I'm having a bit of a hard time doing so

Yes, the side is changed, and I made it so the packets updated when the mana is changed now, still the display isnt updating properly. and resets to 0 on relog

Okay, this seemed to work better.. on logging in It was synced until I subtracted w/ the infusion recipe, in which it desynced again: CapabilityManaData storage = mc.thePlayer.getCapability(CapabilityMagic.MANA, null); PlentifulMisc.network.sendToServer(new ManaNetworkSyncClient(storage.getManaStored())); String string = "MANA: " + Integer.toString(storage.getManaStored()); mc.fontRendererObj.drawString(string, 50 + 1, 50, 50); the output: 8000 8000 8000 8000 8000 8000 8000 500 8000 500 8000 500 8000 8000 500 500 8000 500

That seemed to fix my error, however Its still not updating my display, do I need to do something here?: CapabilityManaData storage = mc.thePlayer.getCapability(CapabilityMagic.MANA, null); String string = "MANA: " + Integer.toString(storage.getManaStored()); mc.fontRendererObj.drawString(string, 50 + 1, 50, 50);

Yeah, still the same error

Yeah I had one here: public ManaSyncMessageClient(){}

Okay, steps closer, however, now I'm getting this crash: java.lang.RuntimeException: java.lang.InstantiationException: com.lambda.plentifulmisc.PlentifulMisc$ManaSyncMessageClient$MessageHandler at

is the updated packet: class ManaSyncMessageClient implements IMessage { private int mana; public ManaSyncMessageClient(){} public ManaSyncMessageClient(int toSend) { this.mana = toSend; } @Override public void toBytes(ByteBuf buf) { // Writes the int into the buf buf.writeInt(mana); } @Override public void fromBytes(ByteBuf buf) { // Reads the int back from the buf.

Closer..? @Override public IMessage onMessage(PMMessages message, MessageContext ctx) { IThreadListener mainThread = (WorldServer) ctx.getServerHandler().playerEntity.worldObj; // or Minecraft.getMinecraft() on the client mainThread.addScheduledTask(new Runnable() { @Override public void run() { CapabilityManaData cap = ctx.getServerHandler().playerEntity.getCapability(CapabilityMagic.MANA, null); cap.setManaStored(mana); System.out.println(String.format("Received %s from %s", message.mana, ctx.getServerHandler().playerEntity.getDisplayName())); } }); return null; // no response in this case }

Okay so something like this? public class MessageHandler implements IMessageHandler<Messages, IMessage> { @Override public IMessage onMessage(Messages message, MessageContext ctx) { EntityPlayerMP serverPlayer = ctx.getServerHandler().playerEntity; int amount = message.mana; if(serverPlayer.hasCapability(CapabilityMagic.MANA, null)) { CapabilityManaData cap = serverPlayer.getCapability(CapabilityMagic.MANA, null); amount += cap.getManaStored(); } return null; } } If so how would I access ti and access the amount variable.

Okay, that was pretty easy:) , now would would I register it so that capability data is 'packet-ized?' :^)
