Object Priorities

[scheusso]

Outline

In order to reduce network traffic we do not synchronise every object on every (network-) tick. We only transfer a part of the objects based on their priority. Now we need an instance that provides per-client information about the importance of objects in the universe.

How to determine the priority

The priorities must be based on the following information:

• Distance between the player and the object
• Importance of the object (e.g. Asteroids don't change their rotationrate and velocity and can be precalculated well by the client)

Current status

There has already been a lot done here by chpeter:

• the TrafficControl class processes a list of objects, sorts it and cuts it down to the desired size
• this list afterwards gets processed by the gamestate and affects directly what gets sent to the client

further things to do:

• better integration into the rest of orxonox
• considering of compression
• communication of clients bandwidth
