Rust Oxide/uMod hook reference

Every hook the uMod Rust game extension raises — 477 hooks across 20 categories — with its description, its return contract and the C# signature to declare in a plugin.

Scraped verbatim from umod.org/documentation/games/rust on 2026-09-15. This is a mirror for reference, not a specification we own: uMod is upstream and wins any disagreement. See README.md for what it is for and how to refresh it.

How to read an entry

Each hook gives three things:

• What it is called for — the game moment that raises it.

• Return behaviour — the hook's contract, and the only part that is load-bearing. Oxide reads the value your method returns and one of four things is true:

  Contract	Meaning
  No return behavior	The hook is a notification. Return void; nothing you return is read.
  Returning a non-null value overrides default behavior	The hook is a veto with a payload. Declare it object; return null to let the game proceed, anything else (conventionally true/false) to cancel the default action.
  Returning true or false overrides default behavior	A veto. Declare it object; return null to abstain — returning false is not the same as abstaining.
  Returning a string will kick… (and similar)	The returned value is consumed as data, not just as a veto.

• Signature — the exact method to declare. Oxide binds hooks by name and arity, by reflection, at runtime: there is no interface to implement and no compile-time check. A typo in the name, or the wrong parameter types, means the method is silently never called.

Two cautions that apply to the whole table. (1) Never return a non-null value from a hook whose contract is no return behavior — on some hooks Oxide will still treat it as a veto. (2) When several plugins hook the same veto, the first non-null return wins and the remaining plugins are not consulted; abstain with null unless you mean to decide.

Categories

Category	Hooks	What it covers
Server	17	Process lifecycle, the tick/frame loop, save and restart, RCON and console commands.
Player	138	Everything a connected human does: connect, chat, command, craft, loot, build, die, respawn. The largest surface alongside Entity.
Entity	140	The generic BaseEntity graph — spawn, kill, damage, mount, loot, flags. Anything in the world that is not specifically an item.
Item	43	Item stacks and containers: add, remove, split, stack, move, repair, research, craft, use.
Resource	12	Gathering and node dispensers — ore, trees, corpses, collectibles, quarries.
Structure	15	Building blocks: placement, upgrade, demolish, rotate, stability, doors and locks.
Terrain	1	Terrain/map topology.
Vending	16	Vending machines and the shop/trade flow, including the marketplace and drone deliveries.
Weapon	16	Firing, reloading, throwing, melee swings, projectile and trap behaviour.
Vehicle	22	Boats, cars, horses, helicopters, trains, submarines — fuel, engines, mounting, pushing.
Team	12	Rust's built-in team/party system: create, invite, join, leave, promote, disband.
World	1	World-level generation events.
Fishing	4	The fishing minigame.
Electronic	2	The electricity graph.
Clan	7	The first-party clan system (distinct from Team).
Plugin	4	Plugin lifecycle inside Oxide itself — Loaded, Unload, and compilation.
Sign	3	Sign painting, updating and locking.
TechTree	4	Tech tree node unlocks and their prerequisites.
Phone	12	In-game telephones: dialling, answering, voicemail, directory.
Permission	8	uMod's own permission/group system (Covalence) — grants, revokes, group membership.
Total	477

Server Hooks

Process lifecycle, the tick/frame loop, save and restart, RCON and console commands.

17 hooks: Init, OnMessagePlayer, OnServerCommand, OnServerRestartInterrupt, OnServerShutdown, OnFrame, OnServerInformationUpdated, OnRconCommand, OnPluginLoaded, OnRconConnection, OnNewSave, OnPluginUnloaded, OnSaveLoad, OnServerInitialized, OnServerMessage, OnServerSave, OnTick

Init

• Called when a plugin is being initialized
• Other plugins may or may not be present, dependant on load order

Returns: No return behavior

void Init()
{
    Puts("Init works!");
}

_{uMod last updated 2018-08-20}

OnMessagePlayer

• Useful for intercepting server messages before they get to their intended target

Returns: Returning a non-null value overrides default behavior

object OnMessagePlayer(string message, BasePlayer player)
{
