Скачать или смотреть U3D Game Engine Fog Of War Prototype

A network prototype demonstrating decision-function based network replication implemented in U3D C++ Game Engine (https://u3d.io/).

Two clients see different parts of the same server scene, based on node-settings, a replication function and runtime flags, while regular objects are replicated as usual (not shown in this video).

Cylinders represent the connections 'Avatar'. The decision function is driven by proximity of objects to the avatar and based on their internal flags (private, fow, invis, global).

Tori demonstrate fog of war concept (States: unseen, green=currently visible and updated, brown=seen but not up to date (FOW)). A callback changes the object model.

Sphere demonstrates a private object (only visible to connection)
Regular objects are replicated as usual.

The prototype is implemented by modifying only Urho3D::Connection object and adding a flag to NodeReplicationState. Furthermore a decision-function is used via callback setting the replication and node state flags.
