// This class is needed because RealtimeTransforms use unreliable properties, which means sometimes
// packets are dropped. This normally isn't a big deal, unless your app relies on a single
// programmatic position update. If this single update is dropped, the position of the RealtimeTransform
// will appear very incorrect to other users, but correct to the RealtimeTransform owner.
//
// So to fix this, after a large update we enable the Jiggle script which will jiggle the object back and forth

I had trouble finding information or examples showing how to use RealtimeDictionary, so I put together this doc that details the things I learned as I figured it out.

What is a RealtimeDictionary

RealtimeDictionary isn't a generic C# dictionary that syncs across the network. It specifically maps from uints (unsigned ints, or integers from 0 to ~4 billion) to RealtimeModels. There are other guides which cover RealtimeModels, but they're essentially network-synced structs that can hold whatever data you like.

It's a little complicated if you were just looking to map between two primitive data types, but creating a small RealtimeModel that wraps a single attribute is pretty quick and easy.

Also note that your keys must be unsigned ints. RealtimeDictionary does not support keys of other types.
