#api

A batch of networking API facts, verified from the installed build's source and XML, that overturn common assumptions when you plan multiplayer code before it touches the compiler. LobbyInformation is a struct, so a null guard does not compile. Networking.Connections is deprecated in favour of Connection.All and emits CS0618. Connection.MaxChunkSize is internal, so game code hard-codes the 131072 value instead of referencing the symbol. NetworkAccessor exposes Owner, OwnerTransfer, and OrphanedMode as get-only, with AssignOwnership, SetOwnerTransfer, and SetOrphanedMode called after NetworkSpawn. Networking.TryConnectSteamId exists and is public. SB1000 whitelisting is assembly-level, so the real constraint on a networking call is public versus internal accessibility, not the whitelist. A green dotnet build does not mean an editor-green result for networked types.

Sandbox.PlayerController's WalkSpeed / RunSpeed / DuckedSpeed / Speed are private serialized [Property] fields, so an external component can't cleanly scale player move speed (e.g. for a slow/root effect). WishVelocity is public but recomputed every fixed-update, so writing it is order-dependent. Swap in or subclass a controller that exposes a public knob.

The game-reachable engine surface has no scene/global time-scale multiplier: Scene.TimeScale does not exist, and the only TimeScale anywhere is on ParticleEffect. Sandbox.Time is read-only. A slow-mo / fast-forward feature must scale each system's own Time.Delta reads, or expose a hook for a future native mechanism.
