Hi, I'm still working on the portals for my botania addon, This time, the problem is that data is not syncing between the server and client. when I activate a portal - you can go through it, but none of the animations show up.

here is my source code:

What I think is happening is, mana is handled on the server(I think) so there will never be any on the client, right?

Do I need to notify every client when a portal activates/deactivates?

What do I have to do?

 

If you can tell me Thanks! :D

Yes, you should notify it every time something client-related changes.

Call World::notifyBlockUpdate with the current blockstate for both old and new for that.

Thanks, I thought I had to send a packet to every client player :) 

EDIT: Trying to update the TE, not the block.

I'm not sure about the intricacies of botania, but if you want to update other client-rendering things like having particles on tile entities usually you need a packet. 

 

You want to write two messages. 

 

1. A message notifying the players in the area that the portal is active. (Which will then client-side show the particles.)

2. A message notifying the server that the player wants to recieve an update on whether the portal is active or not.

 

then in the custom TileEntity class you do something like.

  

    @Override
    public void onLoad() {
        if (worldObj.isRemote) {
            Your update message
        }
    }

to tell the client you want the portal active. 

 

When your block activates you want to make a sendToAllAround message that tells people around it that the portal is active. 

 

If you'd add that then players who walk from afar and load your TE will know the portal is active, and players who are near when it activates will know it's active. You don't have to send a packet with every particle, just tell the client it's active and make it use particles from there.

Christ. This isn't that complicated folks.

 

Step 1: Override these methods

Step 2: Call these methods whenever the data changes and the client needs to know about it

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

AFAIK notifyBlockUpdate is sufficient.

It works both on TEs and Blocks, GiantNuker.

Hello, I have similar problem with client server synchronization, it's just I want to update energy in my TE to client every tick, but I do not find there code can update custom data in TE.

Don't bump an over-half-year-old thread. Just make your own issue thread with what you've tried.

^^^ Very good advice, please never comment on existing threads with a new issue.

@Ice2670 Since you haven't made a new thread yet, and this is a common issue, I'll show how I do it. This is my personal preference, and it works well for me, feel free to adapt it. My personal preference is to have a superclass that handles all my syncing & capability stuff and have all my TileEntities extend it. My class is called TileEntityBase and you can view it here. It is adapted from canitzp's mod MetalWorks.

The actual Syncing packets are registered here, and the class is here.

To get my energy capability I simply Override getEnergy() in my superclass.

You can see an examples of how I use TileEntityBase here, here and here.
