[1.7] Persistence with IExtendedEntityProperties

[MrRiegel]

hello,

 

I want to save data to player and I use IEEP. So far, so good.

The data survive logout and death.

But when I go from death screen directly to title screen the data is lost.

How can I fix this?

 

IEEP:

public class PlayerInformation implements IExtendedEntityProperties {

public final static String EXT_PROP_NAME = "PlayerInformation";

private final EntityPlayer player;
private HashMap<String, Boolean> layerBools = new HashMap<String, Boolean>();
private HashMap<String, Boolean> questBools = new HashMap<String, Boolean>();
private HashMap<String, Integer> questNums = new HashMap<String, Integer>();

public PlayerInformation(EntityPlayer player) {
	this.player = player;
	for (String s : BlockedLayers.names) {
		questBools.put(s, false);
		questNums.put(s + "Num", 0);
	}
	for (String s : BlockedLayers.layer) {
		layerBools.put(s, false);
	}

}

public static final void register(EntityPlayer player) {
	player.registerExtendedProperties(PlayerInformation.EXT_PROP_NAME,
			new PlayerInformation(player));
}

public static final PlayerInformation get(EntityPlayer player) {
	return (PlayerInformation) player.getExtendedProperties(EXT_PROP_NAME);
}

@Override
public void saveNBTData(NBTTagCompound compound) {
	NBTTagCompound properties = new NBTTagCompound();

	for (Entry<String, Boolean> entry : layerBools.entrySet()) {
		properties.setBoolean(entry.getKey(), entry.getValue());
	}

	for (Entry<String, Boolean> entry : questBools.entrySet()) {
		properties.setBoolean(entry.getKey(), entry.getValue());
	}

	for (Entry<String, Integer> entry : questNums.entrySet()) {
		properties.setInteger(entry.getKey(), entry.getValue());
	}

	compound.setTag(EXT_PROP_NAME, properties);

}

@Override
public void loadNBTData(NBTTagCompound compound) {
	NBTTagCompound properties = (NBTTagCompound) compound
			.getTag(EXT_PROP_NAME);

	for (Entry<String, Boolean> entry : layerBools.entrySet()) {
		entry.setValue(properties.getBoolean(entry.getKey()));
	}
	for (Entry<String, Boolean> entry : questBools.entrySet()) {
		entry.setValue(properties.getBoolean(entry.getKey()));
	}
	for (Entry<String, Integer> entry : questNums.entrySet()) {
		entry.setValue(properties.getInteger(entry.getKey()));
	}

}

private static final String getSaveKey(EntityPlayer player) {
	return player.getCommandSenderName() + ":" + EXT_PROP_NAME;
}

public static final void loadProxyData(EntityPlayer player) {
	PlayerInformation playerData = PlayerInformation.get(player);
	NBTTagCompound savedData = ServerProxy
			.getEntityData(getSaveKey(player));
	if (savedData != null) {
		playerData.loadNBTData(savedData);
	}
}

public static final void saveProxyData(EntityPlayer player) {
	PlayerInformation playerData = PlayerInformation.get(player);
	NBTTagCompound savedData = new NBTTagCompound();

	playerData.saveNBTData(savedData);
	ServerProxy.storeEntityData(getSaveKey(player), savedData);
}

@Override
public void init(Entity entity, World world) {

}

public HashMap<String, Boolean> getLayerBools() {
	return layerBools;
}

public HashMap<String, Boolean> getQuestBools() {
	return questBools;
}

public HashMap<String, Integer> getQuestNums() {
	return questNums;
}

}

 

SyncHandler:

public class SyncHandler {

@SubscribeEvent
public void onLivingDeathEvent(LivingDeathEvent event) {
	if (!event.entity.worldObj.isRemote
			&& event.entity instanceof EntityPlayer) {
		EntityPlayer player = (EntityPlayer) event.entity;
		NBTTagCompound playerData = new NBTTagCompound();
		((PlayerInformation) (player
				.getExtendedProperties(PlayerInformation.EXT_PROP_NAME)))
				.saveNBTData(playerData);
		ServerProxy.storeEntityData(player.getCommandSenderName(),
				playerData);
		PlayerInformation.saveProxyData((EntityPlayer) event.entity);
	}
}

@SubscribeEvent
public void onEntityConstructing(EntityConstructing event) {
	if (event.entity instanceof EntityPlayer) {
		EntityPlayer player = (EntityPlayer) event.entity;
		if (PlayerInformation.get((EntityPlayer) event.entity) == null) {
			PlayerInformation.register(player);
		}
	}
}

@SubscribeEvent
public void respawn(EntityJoinWorldEvent event) {
	if (!event.entity.worldObj.isRemote
			&& event.entity instanceof EntityPlayer && !event.entity.isDead) {
		EntityPlayer player = (EntityPlayer) event.entity;

		NBTTagCompound playerData = ServerProxy.getEntityData(player
				.getCommandSenderName());
		if (playerData != null) {
			(player.getExtendedProperties(PlayerInformation.EXT_PROP_NAME))
					.loadNBTData(playerData);
		}
		PlayerInformation props = PlayerInformation.get(player);

	}

}
}

 

Proxy:

public class ServerProxy extends CommonProxy implements IGuiHandler {

private static final Map<String, NBTTagCompound> extendedEntityData = new HashMap<String, NBTTagCompound>();

@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world,
		int x, int y, int z) {
	return null;
}

@Override
public Object getClientGuiElement(int ID, EntityPlayer player, World world,
		int x, int y, int z) {
	return null;
}

public static void storeEntityData(String name, NBTTagCompound compound) {
	extendedEntityData.put(name, compound);
}

public static NBTTagCompound getEntityData(String name) {
	return extendedEntityData.remove(name);
}
}

In simpler words: You are outdated.

 

* IEEP class is cool.

* Clonning data is not cool.

 

What you need:

IEEP = hold data.

EntityConstructing = assign data.

PlayerEvent.Clone = clone data on player re-creation (e.g death).

 

Example:

@SubscribeEvent
public void onPlayerClonning(PlayerEvent.Clone event)
{
IEEP ieepNew = IEEP.get(event.entityPlayer);
IEEP ieepOld = IEEP.get(event.original);

ieepNew.setSomething(ieepOld.getSomething());
}

 

Everything else is old "technique" and you don't need it.

In case you need synchronization - you might wanna look at FML's PlayerEvent#, like: PlayerRespawnEvent, PlayerChangedDimensionEvent.

It works!

I would not have thought that it is so easy.

thank you
