sock.lua is a networking library for LÖVE games. Its goal is to make getting started with networking as easy as possible.
|
||
|
|
|
||
|
|
[Documentation](https://camchenry.github.io/sock.lua/)
|
||
|
|
|
||
|
|
**sock requires [enet](https://github.com/leafo/lua-enet) (which comes with LÖVE 0.9 and up.)**
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
- Event trigger system makes it easy to add behavior to network events.
|
||
|
|
- Can send images and files over the network.
|
||
|
|
- Can use a custom serialization library.
|
||
|
|
- Logs events, errors, and warnings that occur.

# Installation
|
||
|
|
|
||
|
|
1. Clone or download sock.lua.
|
||
|
|
2. Clone or download [bitser](https://github.com/gvx/bitser).\*
|
||
|
|
3. Place bitser.lua in the same directory as sock.lua.
|
||
|
|
4. Require the library and start using it. `sock = require 'sock'`

|
|
\* If custom serialization support is needed, look at [setSerialization](https://camchenry.github.io/sock.lua//index.html#Server:setSerialization).

||
|
|
function love.load()
|
||
|
|
-- Creating a new client on localhost:22122
|
||
|
|
client = sock.newClient("localhost", 22122)
|
||
|
|
|
||
|
|
-- Creating a client to connect to some ip address
|
||
|
|
client = sock.newClient("198.51.100.0", 22122)
|
||
|
|
|
||
|
|
-- Called when a connection is made to the server
|
||

|
||
|
|
print("Client connected to the server.")

|
|
print("Client disconnected from the server.")
