Like remote procedure calls, SyncTypes are another type of communication. These are fields which automatically synchronize over the network to clients when the server changes them. There are a variety of SyncTypes available: SyncVar, SyncDictionary, SyncList, custom SyncTypes, and more.

When changes are made to a SyncType, only the changes are sent. For example, if you have a SyncList of 10 values and add another, only the just added entry will be sent.

SyncTypes will also automatically generate serializers for custom types.

Any changes made to SyncTypes in Awake will be performed on server and client without requiring synchronization. This is a great opportunity to add to lists or dictionaries. If you wish values to be synchronized after initializing use OnStartServer.

Setting a SendRate of 0f will allow SyncTypes to send changes every network tick.
