From AlliedModders Wiki
Jump to: navigation, search

SourceMod 1.1 is a major update, containing many features, fixes, and improvements. If you need help upgrading, see Upgrading SourceMod.

  • This release DOES HAVE configuration changes.
  • This release DOES NOT break compatibility.

Plugin Changes

Map Management Changes

SourceMod's map management plugins have gone through huge overhauls to address many community requested features and bugs.

The new "mapchooser" plugin provides a central system for other map-related plugins. In addition:

  • nominations adds nominations into map votes.
  • rockthevote lets users start early map votes.
  • nextmap automatically selects the next map.
  • randomcycle randomly selects the next map.

To learn more about the new map management system, see Map Management.

Reserved Slot Changes

Reserved slots has a new reserve type to stop kicking players once a certain number of admins have been reached. There is also a new kick type cvar that selects which heuristic to kick a player by. Available heuristics are ping time, connection time, and randomly.

For more information, see Reserved Slots. Sections specific to SourceMod 1.1 or higher are marked as such.

Gamedata Updater

One major support problem with SourceMod is that when a mod updates, it is quite easy to break SourceMod's SDKTools. SDKTools provides "hacky" scripting functionality for internal game features, like slaying players or creating entities.

To fix this we now have a gamedata auto-updating feature in SourceMod (for gamedata files only). When your server starts, SourceMod will contact AlliedModders to check for gamedata file updates. AlliedModders will send back new files if they are available.

As part of this effort, if your server crashes on load, gamedata files will become locked, and no "hacky" functionality will be available. The motivation behind this is to give your server time to update safely in case plugins are trying to run functions that are doomed to crash.

Only official gamedata files are updated. All gamedata updating functionality can be disabled if you deem it a security risk. For more information, see Gamedata Updating.

Client Prefs

SourceMod 1.1 comes with a new "client preferences" extension. This extension lets plugins configure properties on clients which are preserved across connections, server restarts, and even across multiple servers. Properties are created and maintained by plugins in an API similar to ConVars (cvars).

The Client Prefs extension can be configured to use SQLite (default) or MySQL. All operations are threaded in order to not interrupt gameplay performance.

To read more, see Client Preferences API.

JIT Changes

The concept of "debug mode" has been removed. Debug mode is now always on, and it has been reworked to not be a performance hit. In addition functions are now compiled on-demand rather than all at once on load.

The JIT has received major API changes and is now decoupled from SourceMod. For more information, see this blog post.

Config Changes

  • core.cfg has new options for tweaking gamedata updating.
  • databases.cfg now contains a default entry for client preferences.
  • languages.cfg now contains the new user-translated languages.
  • maplists.cfg has been extended for the new map management plugins.
  • plugin_settings.cfg no longer has debug settings.


This release is fully backwards compatible. It is not, however, forwards compatible. Plugins compiled against SourceMod 1.1 will not run on any earlier version.
