i just want to ask if you gus know any good entity creating tuts

ok i figured out what was wrong now it dont crashes but what now?

Your PlayerDataMessage#fromBytes method is trying to read more data from the byte buffer than was written to it by PlayerDataMessage#toBytes . You must read exactly the same number of bytes from the buffer that you write to the buffer. If you post the PlayerDataMessage class, I may be able to tell you in more detail what you've done wrong. but the PlayerDataMessage is just a empty message class just prepared for later to implement data sync... package pl.minepack.gym.network; import io.netty.buffer.ByteBuf; import net.minecraft.client.Minecraft; import net.minecraft.entity.player.EntityPlayerMP; import net.minecraft.init.Items; import net.minecraft.item.ItemStack; import net.minecraft.util.IThreadListener; import net.minecraft.world.WorldServer; import net.minecraftforge.fml.common.network.simpleimpl.IMessage; import net.minecraftforge.fml.common.network.simpleimpl.IMessageHandler; import net.minecraftforge.fml.common.network.simpleimpl.MessageContext; public class PlayerDataMessage implements IMessage { private int Strength = 0; // A default constructor is always required public PlayerDataMessage(){} public PlayerDataMessage(int Strength) { this.Strength = Strength; } @Override public void toBytes(ByteBuf buf) { buf.writeInt(Strength); } @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. Strength = buf.readInt(); } // The params of the IMessageHandler are <REQ, REPLY> // This means that the first param is the packet you are receiving, and the second is the packet you are returning. // The returned packet can be used as a "response" from a sent packet. public static class PlayerDataMessageHandler implements IMessageHandler<PlayerDataMessage, IMessage> { // Do note that the default constructor is required, but implicitly defined in this case @Override public IMessage onMessage(PlayerDataMessage message, MessageContext ctx) { IThreadListener mainThread = (WorldServer) ctx.getServerHandler().playerEntity.worldObj; mainThread.addScheduledTask(new Runnable() { @Override public void run() { } }); // No response packet return null; } } }

i have this code: package pl.minepack.gym.capabilities; import java.util.concurrent.Callable; import net.minecraft.nbt.NBTBase; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.util.EnumFacing; import net.minecraftforge.common.capabilities.Capability; public class PlayerDataCapabilityClass { public interface PlayerDataCapability { int Strength = 0; public int addStrength(int count); public int subStrength(int count); public void setStrength(int count); public int getStrength(); } public static class PlayerDataCapabilityStorage implements Capability.IStorage<PlayerDataCapability> { @Override public NBTBase writeNBT(Capability<PlayerDataCapability> capability, PlayerDataCapability instance, EnumFacing side) { NBTTagCompound nbt = new NBTTagCompound(); nbt.setInteger("Strength", instance.getStrength()); return nbt; } @Override public void readNBT(Capability<PlayerDataCapability> capability, PlayerDataCapability instance, EnumFacing side, NBTBase nbt) { instance.setStrength(((NBTTagCompound)nbt).getInteger("Strength")); } } public static class PlayerDataCapabilityFactory implements PlayerDataCapability { private int Strength = 0; @Override public int addStrength(int count) { return this.Strength += count; } @Override public int subStrength(int count) { return this.Strength -= count; } @Override public void setStrength(int count) { this.Strength = count; } @Override public int getStrength() { // TODO Auto-generated method stub return this.Strength; } } } and what now?

Maybe add a public variable InfoAdded = false to the Item Class and check for it in the Add Info method

can you show me an example?

Call ICapabilityProvider#getCapability to get the instance of your handler attached to the provider. Every Entity (including EntityPlayer ) is an ICapabilityProvider . where i need to call this and how do i read/write the data?

ok i have created and registered capability but how do i use it?

So i need to pass a PlayerDataCapabilityClass.PlayerDataCapabilityFactory.this as a third argument?

It says "The method register(Class<T>, Capability.IStorage<T>,Class<? extends T>) is not applicable for arguments(Class<PlayerDataCapabilityClass.PlayerDataCapability>,Class<PlayerDataCapabilityClass.PlayerDataCapabilityStorage>,Class<PlayerDataCapabilityClass.PlayerDataCapabilityFactory>)"

few questions: 1.Where i shloud register my capabliity 2.i have an error when i am trying to register a capability eclipse marks this with red line: CapabilityManager.INSTANCE.register(PlayerDataCapabilityClass.PlayerDataCapability.class, PlayerDataCapabilityClass.PlayerDataCapabilityStorage.class, PlayerDataCapabilityClass.PlayerDataCapabilityFactory.class); PlayerDataCapabilityClass.java: public class PlayerDataCapabilityClass { public interface PlayerDataCapability { } public static class PlayerDataCapabilityStorage implements Capability.IStorage<PlayerDataCapability> { @Override public NBTBase writeNBT(Capability<PlayerDataCapability> capability, PlayerDataCapability instance, EnumFacing side) { return null; // return an NBT tag } @Override public void readNBT(Capability<PlayerDataCapability> capability, PlayerDataCapability instance, EnumFacing side, NBTBase nbt) { // TODO Auto-generated method stub } } public static class PlayerDataCapabilityFactory implements Callable<PlayerDataCapability> { @Override public PlayerDataCapability call() throws Exception { return null; } } }

What if i want to Store a int and a boolean shloud i create 2 capabilities?

what i shloud do? Create own capability or use existing one?

can anyone explain this Capabilities system step-by-step because i spend like a 2 weeks to try to figure it out by myself

i think in this RenderManager argument you shloud pass Minecraft.GetMinecraft().GetRenderManager() but i'm not really sure

i have a variable and i need to save it and i have no idea how to use capabilities

ok but is this possible to use the NBTTag?

is there a way to use NBTTag?

Like in topic i want to save some data to player but i have no idea how to do this

Ok now eveything works

what "% 20 == 0" means?

in the Potion#isReady method is only /** * checks if Potion effect is ready to be applied this tick. */ public boolean isReady(int duration, int amplifier) { if (this == MobEffects.REGENERATION) { int k = 50 >> amplifier; return k > 0 ? duration % k == 0 : true; } else if (this == MobEffects.POISON) { int j = 25 >> amplifier; return j > 0 ? duration % j == 0 : true; } else if (this == MobEffects.WITHER) { int i = 40 >> amplifier; return i > 0 ? duration % i == 0 : true; } else { return this == MobEffects.HUNGER; } } what i shloud do with this?

Nausea now works but i dont know how much time poison needs to enable

ok so i need to check if player arelady has a potion to make it work EDIT: i changed my utils.addPotionEffect function to: public static boolean addPotionEffect(EntityLivingBase entity, Potion potion, int duration, int amplifier, boolean showParticles) { if (!entity.isPotionActive(potion)) { entity.addPotionEffect(new PotionEffect(potion, duration, amplifier, false, showParticles)); return true; } return false; and still not works maybe resaon is that i am giving the potion on 1 sec
