Easier way setItemDamage(0) in onArmorUpdate(){} event

Ohhh Thanks for the explanation

It is quite interesting I solved problem but it is weird... if(data.readInt() == 2002) is not working... int id = data.readInt(); if(id ==2002) is working... Weird but it is working

And I just realised that I am getting this exception when I try to data.readInt() java.io.EOFException 2013-08-04 00:15:05 [iNFO] [sTDERR] at java.io.DataInputStream.readInt(Unknown Source) 2013-08-04 00:15:05 [iNFO] [sTDERR] at netherfors.misc.PacketReadStream.readInt(PacketReadStream.java:53) 2013-08-04 00:15:05 [iNFO] [sTDERR] at netherfors.ServerModPacketHandler.onPacketData(ServerModPacketHandler.java:28) 2013-08-04 00:15:05 [iNFO] [sTDERR] at cpw.mods.fml.common.network.NetworkRegistry.handlePacket(NetworkRegistry.java:255) 2013-08-04 00:15:05 [iNFO] [sTDERR] at cpw.mods.fml.common.network.NetworkRegistry.handleCustomPacket(NetworkRegistry.java:245) 2013-08-04 00:15:05 [iNFO] [sTDERR] at cpw.mods.fml.common.network.FMLNetworkHandler.handlePacket250Packet(FMLNetworkHandler.java:83) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.network.NetServerHandler.handleCustomPayload(NetServerHandler.java:1098) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.network.packet.Packet250CustomPayload.processPacket(Packet250CustomPayload.java:70) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.network.MemoryConnection.processReadPackets(MemoryConnection.java:89) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.network.NetServerHandler.networkTick(NetServerHandler.java:134) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.network.NetworkListenThread.networkTick(NetworkListenThread.java:53) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.server.integrated.IntegratedServerListenThread.networkTick(IntegratedServerListenThread.java:109) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:675) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:571) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:127) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:469) 2013-08-04 00:15:05 [iNFO] [sTDERR] at net.minecraft.server.ThreadMinecraftServer.run(ThreadMinecraftServer.java:16) And this is how I handle my packets http://www.minecraftforge.net/wiki/Organising_packet_handlers

I added this code to the handler : System.out.println("PACKET ARRIVED!"); System.out.println(packet.channel); System.out.println(data.readInt()); And channel is ok , packet is arriving , integer is running but the if statement its not working it looks like ... :?

I am still in 1.5.2 and thats in the : @Init public void init(FMLInitializationEvent event){}

I can get the packet in single player so yes! IPacketHandler packetServer = new ServerModPacketHandler(); IPacketHandler packetClient = new ClientModPacketHandler(); NetworkRegistry.instance().registerChannel(packetServer, "netherfors", Side.SERVER); NetworkRegistry.instance().registerChannel(packetClient, "netherfors", Side.CLIENT);

When I send a packet to the server If I am in the client it does work but in the multiplayer it doesnt work... I send my packet : EntityClientPlayerMP pl = (EntityClientPlayerMP) player; pl.sendQueue.addToSendQueue(stream.makePacket("netherfors")); And my server packet handler : package netherfors; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.network.INetworkManager; import net.minecraft.network.packet.Packet250CustomPayload; import netherfors.misc.PacketReadStream; import cpw.mods.fml.common.network.IPacketHandler; import cpw.mods.fml.common.network.Player; public class ServerModPacketHandler implements IPacketHandler { @Override public void onPacketData(INetworkManager manager, Packet250CustomPayload packet, Player player) { EntityPlayer p = (EntityPlayer) player; if(packet.channel.equals("netherfors")){ PacketReadStream data = new PacketReadStream(packet); if(data.readInt() == 1001){ p.addChatMessage("Done!"); } if(data.readInt() == 2002){ System.out.println("2002"); destroyPhoxNote(p); } } } public void destroyPhoxNote(EntityPlayer player){ player.closeScreen(); player.inventory.decrStackSize(player.inventory.currentItem, 1); player.addChatMessage("You have successfully learned what this Phox Note teaches!"); } } Can anyone help with this ?

Hey dude! Thank you for your help I successfully defined the server and the client proxy but here is the deal : With an item I am sending a packet to server with int(1001) When packet handler gets the int(1001) prints a "Done!" It works on singleplayer still but doesnt work on the multiplayer And I am okey with you saying me I am newbie! Because I am a newbie

Actually I am using 1 packet handler I dont know how to create sided handlers

All nice in the single player No fake items or nothing like that But in multiplayer it acts like it doesnt get the packet...

With your classes it looks easy...Can I use these classes in my mod ?

You know about packets it looks like Can you give me an example about how to send integers and execute them a fast one Because the packet tutorial on wiki is very complicated

Okey thanks for help I will have a look in packets and implement that into my mod! Thanks one more!

You cant depent on packets because players easily can exploit them And they are actually complicated

God! This topic is going crazy Guys all I am trying to do is giving player items when you click a button but guis are clientsided so i cant do it This is my problem can anyone help ?

Dude just check out my mod I detect the items in the players inventory and give the player an item if the player has the needed items But when you add @SideOnly(Side.CLIENT) or IGuiHandler the Gui only gets opened in the client and it prevents you from spawing items etc

yes

Dude it spawns one item and it is fake

I converted all of my code into IGuiHandler but now world.spawnEntityInWorld() spawns fake items as well Still have the problem...

Ohh god ! This was easier...I was using IGuiHandler for only containers but now I should use it for GuiScreens too Thanks for help dude I will try it and tell the result here

If i dont use it it crashes the server because it attemps to render on server too

Hi I have a mod full of Guis and I had a problem with the guis crashing the server as soon as I added @SideOnly(Side.CLIENT) to the onItemRightClick command it fixed the problem but the new problem is that I used to have guibuttons that when you click drops item @SideOnly(Side.CLIENT) annotation brokes them!! What can I do about this ?

These are all while player is online... I want to be able to save into player nbt while player is offline...(NOT LOGGED into the server)
