Posted May 15, 20178 yr Hi everyone I created a custom capability for my mod which is attached to the player. I would like to know how to save or recover it's content after the player left the World/Server. (to get it back when he reconnects) It gets lost because the game creates a new entity at the player's loggin and doesn't reuse the old one. (Solo and Multiplayer Server)
May 15, 20178 yr Author @SubscribeEvent public void onEntityConstruct(AttachCapabilitiesEvent.Entity evt) { if (evt.getEntity() instanceof EntityPlayer == false) { return;// mod compatibility: IE Tinkers construct } evt.addCapability(new ResourceLocation(Reference.MOD_ID, "zpstats"), new ICapabilitySerializable<NBTTagCompound>() { IPlayerExtendedProperties inst = MainZombies.CAPABILITY_THIRST.getDefaultInstance(); @Override public boolean hasCapability(Capability<?> capability, EnumFacing facing) { return capability == MainZombies.CAPABILITY_THIRST; } @Override public <T> T getCapability(Capability<T> capability, EnumFacing facing) { return capability == MainZombies.CAPABILITY_THIRST ? MainZombies.CAPABILITY_THIRST.<T>cast(inst) : null; } @Override public NBTTagCompound serializeNBT() { try { return (NBTTagCompound) MainZombies.CAPABILITY_THIRST.getStorage() .writeNBT(MainZombies.CAPABILITY_THIRST, inst, null); } catch (java.lang.ClassCastException e) { return new NBTTagCompound(); } } @Override public void deserializeNBT(NBTTagCompound nbt) { MainZombies.CAPABILITY_THIRST.getStorage().readNBT(MainZombies.CAPABILITY_THIRST, inst, null, nbt); } }); } I have already this in my code is this what you talked about ? (sorry if i'm totaly wrong it's my first mod) If not could you give me an example ? test.java
May 15, 20178 yr Author public class Capabilities { public static void register() { CapabilityManager.INSTANCE.register(IPlayerExtendedProperties.class, new Storage(), InstancePlayerExtendedProperties.class); } public static IPlayerExtendedProperties getPlayerProperties(EntityPlayer player) { if (player == null) { return null; } IPlayerExtendedProperties props = player.getCapability(MainZombies.CAPABILITY_THIRST, null); return props; } public interface IPlayerExtendedProperties { int getThirstLevel(); void setThirstLevel(int value); // --------------- NBTTagCompound getDataAsNBT(); void setDataFromNBT(NBTTagCompound nbt); //summary } public static class InstancePlayerExtendedProperties implements IPlayerExtendedProperties { private int thirstLevel = 20; @Override public NBTTagCompound getDataAsNBT() { NBTTagCompound tags = new NBTTagCompound(); tags.setInteger("getThirstLevel", this.getThirstLevel()); return tags; } @Override public void setDataFromNBT(NBTTagCompound nbt) { NBTTagCompound tags; if (nbt instanceof NBTTagCompound == false) { tags = new NBTTagCompound(); } else { tags = (NBTTagCompound) nbt; } this.setThirstLevel(tags.getInteger("getThirstLevel")); } @Override public int getThirstLevel() { return this.thirstLevel; } @Override public void setThirstLevel(int value) { this.thirstLevel = value; } } public static class Storage implements IStorage<IPlayerExtendedProperties> { @Override public NBTTagCompound writeNBT(Capability<IPlayerExtendedProperties> capability, IPlayerExtendedProperties instance, EnumFacing side) { return instance.getDataAsNBT(); } @Override public void readNBT(Capability<IPlayerExtendedProperties> capability, IPlayerExtendedProperties instance, EnumFacing side, NBTBase nbt) { try { instance.setDataFromNBT((NBTTagCompound) nbt); } catch (Exception e) { //Invalid NBT compound e.printStackTrace(); } } } public static void syncServerDataToClient(EntityPlayerMP p) { MainZombies.logString("Capabilities: sync start"); if (p == null) { return; } IPlayerExtendedProperties props = Capabilities.getPlayerProperties(p); if (props != null) { MainZombies.instance.network.sendTo(new PacketSyncPlayerData(props.getDataAsNBT()), p); MainZombies.logString("Capabilities: sync succes"); } } } public class PacketSyncPlayerData implements IMessage, IMessageHandler<PacketSyncPlayerData, IMessage> { public static final int ID = 50; NBTTagCompound tags = new NBTTagCompound(); public PacketSyncPlayerData() { } public PacketSyncPlayerData(NBTTagCompound ptags) { tags = ptags; } @Override public void fromBytes(ByteBuf buf) { tags = ByteBufUtils.readTag(buf); } @Override public void toBytes(ByteBuf buf) { ByteBufUtils.writeTag(buf, this.tags); } @Override public IMessage onMessage(PacketSyncPlayerData message, MessageContext ctx) { if (ctx.side == Side.CLIENT) { //update it through client proxy PacketSyncPlayerData.checkThreadAndEnqueue(message, ctx); } return null; } private static final void checkThreadAndEnqueue(final PacketSyncPlayerData message, final MessageContext ctx) { IThreadListener thread = MainZombies.proxy.getThreadFromContext(ctx); thread.addScheduledTask(new Runnable() { public void run() { // msg.process(ModMain.proxy.getPlayerEntity(ctx), ctx.side); MainZombies.proxy.setClientPlayerData(ctx, message.tags); } }); } } ok this should be everything As said I'm still a beginner in this and I don't undersand everything yet. And I haven't found much about this on the internet either. I took most of this from this mod https://github.com/LothrazarMinecraftMods/OverpoweredInventory
May 15, 20178 yr Author That's the problem each time I get back into my World or Server the value is set back to 20 instead of the value befor I left it and I don't know why.
May 16, 20178 yr Author I check it by displaying it in the logs public void readData() { MainZombies.logString("======= readData Start"); if(!player.hasCapability(MainZombies.CAPABILITY_THIRST, null)) return; IPlayerExtendedProperties prop = Capabilities.getPlayerProperties(player); if (prop != null) { this.thirstSaturation = prop.getThirstLevel(); MainZombies.logString("======= " + prop.getThirstLevel()); } MainZombies.logString("======= readData succes"); } And I think I found the issue public ThirstLogic(EntityPlayer player) { this.thirstLevel = Reference.MAX_THIRST_LEVEL; this.thirstSaturation = Reference.MAX_THIRST_SATURATION; this.player = player; this.thirstSource = new DamageThirst(); readData(); } I don't konw how to fix it tho. The readData function gives the good number now but "thirstLevel" doesn't change it stays at 20 even if the read function wants to set it to an other number
May 16, 20178 yr Author Omg I found it and it was stupid I just autocomplited the wrong var in the readData function x/ well ty for you help I would never have checked that. It seems to work now x)
May 20, 20178 yr Author Sorry I had a busy week This readData method is in the same class and it gets the vars stored in the capability attached to the player. Why ?
May 20, 20178 yr Author maybe it isn't the right way to do it but thats how I get et ThirstLevel var from the players capability (serverSide)
May 20, 20178 yr Author the class ThirstLogic that handles all Thirst related things and exists when a player joins the world. "get......" is the method that takes the information out of the storage. Or is there a way to get the players capability informaions in a better way ? (this part of the code is inspired by the "OverpoweredInventory Mod") https://github.com/LothrazarMinecraftMods/OverpoweredInventory/blob/master/src/main/java/com/lothrazar/powerinventory/inventory/GuiOverpowered.java line 42 for exemple
May 20, 20178 yr Author Ok you asked for it here it is https://github.com/Pierre68/ZApocalypse/tree/master/java/fr/exodeus/zombies I know that it is probably horrible to look at but as said I'm still trying to learn x)
May 20, 20178 yr Author I know I know and no thanks :P. - I changed the identifier to UUID is it at least better ? x) It doesn't need to be perfect for me and my friends to have fun with it, so I will maybe redo it properly the day I realy need to and know how to do everything (if that happens one day x) )
May 20, 20178 yr Author That's the problem I have no idea how to do most of all the things I need and only got it to work by trying random things. My only way of learning so far has been youtube and this Forum. And by the way I'm using the mod for several days now and it never crashed a single time. (not that I think my code is good but at least it does somehow what I want it to do and thats atleast something) I understand that I have many things to change I simply don't know how or if it would be better without an exemple to base my code of.

May 20, 20178 yr Author anyway I removed this event. that was old code that I had forgoten it wasn't doing anything
May 22, 20178 yr Author Ok I reworked the part that you disliked and finaly removed the class that you so strongly hated x) Is it better now or are there still huge mistakes ? https://github.com/Pierre68/ZApocalypse/tree/master/forge-1.11.2-13.20.0.2228-mdk/src/main/java/fr/exodeus/zombies Edited May 22, 20178 yr by Rhym
