HARFANG® 3D Server - Client

This app demonstrates the usage of UDP Sockets using the HARFANG API in Python in order to link a server and one or more clients.

It also includes some basic client prediction and interpolation.

To run the prototype:

  1. Download or clone this repository to your computer (eg. in C:/server_client_3D).
  2. Download assetc for your platform from here to compile the resources.
  3. Drag and drop the resources folder on the assetc executable -OR- execute assetc passing it the path to the resources folder (eg. assetc C:/server_client_3D/server_client_demo).

assetc drag & drop

After the compilation process finishes, you will see a server_client_demo_compiled folder next to resources ( server_client_demo ) folder.

You can now execute the server from the folder you unzipped it to.

C:/server_client_3D>python server.py

You can then execute as many clients as you'd like with the following command (you will get limited by packet size at some point which is a problem I need to fix).

C:/server_client_3D>python main.py

Make sure to reference the correct IP and have your ports open on local AND online networks.
