Network Packets

Network Packets is a plugin that adds the Packet mod element to MCreator, with which you can execute code and send data between the two logical sides of client and server.

This is a java plugin and requires java plugins to be enabled.

How to use?

The first step is to create the procedure that the packet will execute. If you want to pass a string over from one logical side to another, you will need to use the inboundString text dependency from advanced procedures, but that is completely optional. In this example, I will showcase a procedure that the packet will execute on the client.

After making the packet, you can send it from the server to the client, or from the client to the server. The string you send, if you send it, will travel over to the other logical side. For example in this case, the string is being used to set an NBT on the client which can then be used in a client-side condition for GUIs.

For more advanced usage, you can install the file manager plugin. With this, you can turn a JSON object into a string in order to use it with a packet. You can then parse the stringified JSON in order to access all of the properties.
