Hey I've been working on this for a week now, searching and reading up on all the posts about this and the tutorials. However I get crashes when I register my custom packets/messages

"net.registerMessage(customPacketHandler.class, customPacket.class, packetId++, Side.SERVER);"

 

From what I read in posts they use the proxies, however I have no idea how to use it, or use it correctly. I can't find any tutorials or read any posts that make sense to me, all I want is to be able to start using custom GUIs to control tileEntities and other information. And so I would like to ask for some kind of example of doing this whole setup, I really would like to get started on this my mod is so backlogged from this.

 

Would anyone be nice enough to show me, how to code "The registering of messages/packets", "Sending the packets/messages", and "receiving these messages/packets in a tileEntity".

 

Also just for references these are the threads I've found and read:

https://gist.github.com/CatDany/4a3df7fcb3c8270cf70b

http://www.minecraftforge.net/forum/index.php/topic,22201.0.html

http://www.minecraftforge.net/forum/index.php/topic,20135.0.html

http://www.minecraftforge.net/forum/index.php/topic,20138.0.html

 

I've tried to understand these and I fail time and time again, and this is my last resort to ask for some kind of visual code example of how to do this. Thanks for any that respond.

Currently updating my Mod to 1.10.2

What crash does it give you? Your code seems alright.

I don't think you need to use proxies, they work fine to me without them.

 

The way I currently use those packets is by sending messages from server to update client's information when it is changed on server.

Since I know it will always be sync I use the info in my client while rendering Gui without worrying about whether it is sync or not. Although I'm sure you can send request-reply message for the info and render on reply handling

If your packet handler is in same class as the packet, try register packet and handler like this:

net.registerMessage(customPacket.customPacketHandler.class, customPacket.class, packetId++, Side.SERVER);

Umm I know this is rude, but may I see how you setup your channel and register your messages?

 

Can PM it if you don't wish to make it public. I have no idea why this isn't working for me and I see everyone saying theirs works really makes me wonder what I'm doing lol

Whole time I just needed to update... now I feel really foolish, Gave everyone a thanks that replied. I can now send packets, so it's time to move on with my mod. I would have never thought it was just an updated required the whole time.
