###TODO
- More datatypes to read/write
Simple example scene I made while playing around trying to make godot talk to a TCP server ( I used Iojs as a TCP server).
To run this you need:
- GodotEngine;
- Node.Js ( or IO.Js)
From Godot to Server:
- Download or clone this repo
- Open the project inside
godot_tcp
in GodotEngine, or run the/build/godot_tcp.exe
if you use windows - Change
host
innode/server.js
to match your IP (i.e.192.168.1.6
), - Open a terminal inside the
node
folder and runserver.js
(in nodejs:node server.js
, in io.js:iojs server.js
), - Write the host and the port, like this
host:port
, - Click connect in the godot_tcp scene,
- Write something in the textEdit,
- Press
Send Data
, - The string you wrote in godot_tcp should appear in the terminal, like this:
Read: <your_string>
You can also make it reply to some hardcoded strings, like bye
and who am I?
So far I can read the data I send to node, and I can send back the same data.
I currently have problems understanding the first 4 bytes of every TCP packet,
so I can't send packets from node to godot without knowing those 4 bytes beforehand.
I found out what the first 4 bytes are: the length of the packet, without the first 4 bytes. So in a packet with 28bytes, the first 4bytes read '24', which is (28-4=24) the length of the packet! This allows me to send packets from node to godot.
