Over two months, cktnals2000 developed and maintained multiplayer features for the TrollsBrigade/CRAVANT-Proto repository using Unity, Photon Networking, and C#. They implemented cross-client projectile synchronization by replacing standard instantiation with PhotonNetwork.Instantiate, ensuring consistent combat behavior in multiplayer sessions. To address gameplay reliability, they fixed area-of-effect damage application by refining target checks and enhancing debug logs, which improved issue diagnosis. In the following month, cktnals2000 delivered DeathBox inventory synchronization on character death, persisting and synchronizing loot across the network with robust input handling. Their work focused on reliable multiplayer interactions, maintainable code, and improved player experience through technical depth.
