Creating Packet Functions

This page goes on a pretty vague explaination. For more in-depth information (Such as Event Directions) you can check out the other pages.

Packet Functions allow the server and client to send a request and receive a response.

Unlike Packet Events, Packet Functions are two-way communication packets. The caller waits for the receiver to process the request and return a value.

Creating a Packet Function

Packet Functions are created inside a network schema using Packeteer.packetFunction().

local Packeteer = require(path.to.Packeteer)

return Packeteer.create({
  Server = {
    RequestData = Packeteer.packetFunction<<>
      { id: number }, -- T
      { name: string, score: number} -- R
    >>(),
  },

  Client = {
    GetPing = Packeteer.packetFunction<<>
      {}, -- T
      number -- R
    >>(),
  },
})

• The first generic type (“T”) defines the arguments sent with the request.
• The second generic type (“R”) defines the value returned by the callback.

Function Ownership

Similar to Packet Events: The location of the function determines who can invoke it:

• Server-owned functions are invoked by the client and handled by the server.
• Client-owned functions are invoked by the server and handled by the client.
