进入存档后，加载完区块，然后就跳转到这个界面：

回到标题界面，重新进入“单人游戏”，发现刚刚进入的存档不见了，同时，控制台报错：

而且，每次从标题界面点击“‘单人游戏”进入存档列表时，控制台都会报如上错误。
加入下列代码后才出现上述异常
我写的一个接口：

public interface PhantasDartle {
/**
* [url=home.php?mod=space&uid=109629]@See[/url] #usePhantasBow()
*/
int MAX = 100;
/**
* @see #usePhantasBow()
*/
int USE = 15;
int getPhantasTicks();
void setPhantasTicks(int ticks);
default void syncPhantasTicks(int ticks) {
setPhantasTicks(ticks);
if (this instanceof ServerPlayerEntity serverPlayerEntity) {
PacketByteBuf buf = new PacketByteBuf(Unpooled.buffer());
buf.writeInt(ticks);
ServerPlayNetworking.send(serverPlayerEntity, CHANNEL, buf);
}
}
/**
* @see ph.mcmod.bows.mixin.MixinLivingEntity#writePhantasTicks(NbtCompound, CallbackInfo)
*/
default void writePhantasTicks(NbtCompound root) {
root.putInt("phantasTicks", getPhantasTicks());
}
/**
* @see ph.mcmod.bows.mixin.MixinLivingEntity#readPhantasTicks(NbtCompound, CallbackInfo)
*/
default void readPhantasTicks(NbtCompound root) {
if (this instanceof ServerPlayerEntity)
syncPhantasTicks(root.getInt("phantasTicks"));
}
/**
* @see ph.mcmod.bows.mixin.MixinLivingEntity#tickPhantasTicks(CallbackInfo)
*/
default void tickPhantasTicks() {
if (getPhantasTicks() > 0)
setPhantasTicks(getPhantasTicks() - 1);
}
/**
* 射出时增加计时
*
* @see #getCallback(ItemStack, ItemStack, World, LivingEntity, double, PersistentProjectileEntity)
*/
default void usePhantasBow() {
syncPhantasTicks(Math.min(getPhantasTicks() + USE, MAX));
MinecraftUtil.print(getPhantasTicks());
}
}

复制代码

在一个静态初始化块里注册事件：

static {
ClientPlayConnectionEvents.INIT.register((handler, client) -> ClientPlayNetworking.registerReceiver(CHANNEL, (client1, handler1, buf, responseSender) -> ((PhantasDartle) client1.player).setPhantasTicks(buf.readInt())));
}

复制代码

混注LivingEntity类，使其继承上述接口：
