Photon Fusion

Exemple of Photon Fusion integration

This exemple is pseudo code giving an idea on how to implement our Network module. It may be different based on your Network Architecture and we recommend you to develop your own implementation.

This example only works in SHARED game mode

This example is based on https://doc.photonengine.com/fusion/current/fusion-100/fusion-102
