# Description This significantly improves the quality of the language system by fixing the mistakes I've made almost a year ago while developing it. Mainly, this throws away the old half-broken way of networking in favor of the component state system provided by RT. Language speaker comp is now shared with SendOnlyToOwner = true, and its state is handled manually. In addition to that, this brings the following changes: - UniversalLanguageSpeaker and LanguageKnowledge are now server-side - DetermineLanguagesEvent and LanguagesUpdateEvent are now shared (so that future systems can be built in shared, if needed) - Everything now uses the ProtoId<LanguagePrototype> type instead of raw strings (god, I hated those so much) - The server-side language system now accepts Entity<T?> arguments instead of EntityUid + T - UniversalLanguageSpeaker is now based on DetermineEntityLanguagesEvent and gets an Enabled field, which allows to turn it off. This may have some use in the future. - Some minor cleanup <!-- TODO MEDIA <details><summary><h1>Media</h1></summary> <p>  </p> </details> --> # Changelog No cl --------- Co-authored-by: VMSolidus <evilexecutive@gmail.com>
