Link to place: CakeMan On Roblox
A mini article on building a custom physics character under Roblox Server
Authority (Workspace.AuthorityMode = Server) from an empty baseplate.
Prior reading: Roblox Server Authority documentation
Chapter 1 — the method, built on a sliding cube The three-part method end to end: a server-owned character, client prediction, and a presentation layer. Four files, about 200 lines, runnable. Start here.
No Humanoid and no CharacterController — just parts and forces, to get you started.
Chapter 1 — two players, two server-owned cubes, full input prediction, resim, and visual smoothing.
Chapter 2 — the cake with noodle arms The natural extension of Chapter 1: the same four files, with the cube replaced by a floppy cake man built from ball sockets. The netcode is unchanged — only the character differs.
Chapter 2 — the same four files, pointed at a stack of cake, plus some crates to knock over.
The Server Authority reference Everything we know about building under SA, for any project rather than this one. Four files: the invariants and silent-failure tables, the platform, the patterns, and the physics-character doctrine. Written to be usable by agents as well as people.

Chapter 1 finished: the driveable cube, predicted and smoothed |

Chapter 2 finished: CakeMan, the arena, and punching |
Download the .rbxl, open it in Studio, and press Test → Server & Clients. Both places
already have Workspace.AuthorityMode = Server set.
WASD drives. In the CakeMan place, walk into someone and swing — the arms do the rest.
samples/cube/ — the finished Chapter 1 scripts, if you'd rather build up
from an empty baseplate than read a finished place. Drop them in at these paths:
| File | Goes to | Class |
|---|---|---|
CubeSim.luau |
ReplicatedFirst |
ModuleScript |
CubePresent.luau |
ReplicatedFirst |
ModuleScript |
CubeClient.local.luau |
ReplicatedFirst |
LocalScript |
CubeServer.legacy.luau |
ServerScriptService |
Script |
Then set Workspace.AuthorityMode = Server by hand in the Properties panel.

LocalScript, .legacy.luau a Script.
