[1.7.10][SOLVED Finally]Tile Entity Questions

[BuddingDev]

Here is a few questions that I dont quite understand:

 

1. How to IO tileEntity data on world IO? (Do I need to call read/write NBT at any position?)

2. TileEntities act strange when reloaded. It always execute client-side. Is this related to Question 1?

[Failender]

Read and write nbt is only for saving data, like when the game is shutting down. It gets called by Minecraft ,no need to do it manually.

What exactly do you mean with acting strange? TE's execute on Server and client side

[Ernio]

1. ALWAYS post your code.

2. ALWAYS define exact problem and situation, not "are acting weird".

3. ITS GOOD TO write what you are after (exactly, not "if it's possible", but "what i want")

(Trying to help in future )

 

As to problem - world calls NBT-saving automatically. Anything that has to be saved in TE, will be savedloaded if you put it in write/read NBT methods.

As to why it's not saving? - When you want TileEntity to save, you need to mark it as "dirty" to inform world that chunk TE is in needs to be saved to disk.

 

this.markDirty() in TE.class

[BuddingDev]

OK, I'll go clear this time:

 

I want a TIleEntity that follows a block, and generates a counter per tick (or more).

That TileEntity generates counters per ticks. Which is fine.

When I load my world to see if it has any problems, it gave me this:

java.lang.InstantiationException: com.wwy.mod.te.techno.TETechnoReplenisher

 

Block class:

TE Class:

http://pastebin.com/uipjaJ7U

 

Interestingly, even the "heal and boost" ability does not activate, it still generates counters...

 

EDIT: So, my objective is, when the counter (datum variable) reaches 1000, find a random player with lowest health, and then heal him ,and boost him.

[BuddingDev]

OK, that Block instance is solved.

 

BUT, problem is, updateEntity() does not go server-side after the world is reloaded...

WorldObj#isRemote always return true after the world is reloaded.

[BuddingDev]

a) But I need to acquire info from that specific tile entity. Do I use World#getTileEntity(Stuff) instead?

b) No problem. I registered it.

[BuddingDev]

Now, it is even more interesting:

 

Block Class:

http://pastebin.com/5jTBbcXt

 

TE Class:

http://pastebin.com/9jPebGpV

 

Now, I have more amended parts. But, everytime I right click onto the block, It always say TileEntity#worldObj#isRemote is true, so, server never responded...?

[BuddingDev]

Can anyone tell me what went wrong in the bottom of the TE class, when I am doing Nbt IO?

I dont seem to b able to save any variable despite any changes!

[BuddingDev]

Like, everything is reset when I rejoin world.

"Datum" points get back to 0 instead of the value of the last load.

 

EDIT: Now I got some debug outputs.

It seems that NBT are read correctly, but somehow it is not properly processed in / into the TileENtity.

[BuddingDev]

Anyone?

[Abastro]

Try printing the datum field every time you changes the field.

Then please post the console log with the value of datum field printed.

[BuddingDev]

Weird, man, server said I have more datum points, but client responded with less.

Do I need any kind of syncing?

Ah that was the problem! As minecraft does not automatically sync your field, you should sync it yourself.

@see TileEntity#onDataPacket(Receive) and TileEntity#getDescriptionPacket(Send)

[BuddingDev]

Looks complicated....

Ah, can I call a method from the client TE to the Server TE through World class?

[BuddingDev]

Any Idea how to do it simply?

[BuddingDev]

NetworkManager net, S35PacketUpdateTileEntity pkt

 

I need help to understand these two arguments

[BuddingDev]

NBTTagCompound tag = new NBTTagCompound();

tag.setInteger("datum", this.datum);

tag.setInteger("currentCooldown", this.currentCountdown);

tag.setInteger("maxCountdown", this.maxCountdown);

 

Alright. I have the code. And then? How to return a Packet in getDescriptionPacket?

[BuddingDev]

It seems that that 'data' parameter can be anything?

 

So, in onDataPacket i will be catching back that nbt again...

What about that "NetworkManager net"? Anything related to IMessage?

 

Do I need to check if getDescriptionPacket() is executed in server?

[BuddingDev]

So,I guess the following meaningless function brings back that nbt and ends this topic right?

ThatPacket#func_148857_g();

[BuddingDev]

Yup. I bet the problem is solved thoroughly, I will take this as a template to build other TileEntities.
