第一次进入世界时TileEntity数据不同步问题

[dong031001]

TileEntity代码: https://github.com/Nuclear-Fusion-Group/Naturalistia/blob/master/src/main/java/com/NuclearFusion/block/tileentity/TileEntityBotanicCrucible.java

问题描述：在第一次进入世界时TileEntity的客户端和服务端数据并未同步，需要更新方块状态才可以达到同步（譬如破坏一个临近的方块）

调试工具输出方块数据：

每Tick更新解决了：

@Override
    public void tick() {
        if(!getWorld().isRemote) {
            BlockState state = world.getBlockState(pos);
            getWorld().notifyBlockUpdate(pos, state, state, 3);
        }
    }

但还是求一个更加效率的解决方案

https://harbinger.covertdragon.team/chapter-07/tile-entity-sync.html#getupdatetag

Harbinger 有专门提到过这个问题的解决方案。在 1.16 中的写法应该一致。

[3TUSK]

void handleUpdateTag(BlockState state, CompoundNBT tag)

[dong031001]

void handleUpdateTag(BlockState state, CompoundNBT tag)

forge-1.16.5-36.1.32_mapped_snapshot_20210309-1.16.5-recomp 无此方法

[3TUSK]

这个方法在 TileEntity 下。真的没有？

[dong031001]

并没有。只有一个注释提到了

/**
    * Get an NBT compound to sync to the client with SPacketChunkData, used for initial loading of the chunk or when
    * many blocks change at once. This compound comes back to you clientside in {@link handleUpdateTag}
    */
   public CompoundNBT getUpdateTag() {
      return this.writeInternal(new CompoundNBT());
   }

可惜方法已经消失了

[3TUSK]

不要管 TileEntity 类里有没有声明，直接在你的类里 @Override 此方法。

这个方法是声明在了 IForgeTileEntity 里的。
