MM:S API Differences

Metamod:Source 1.6.0 makes several API changes which may affect plugins. These changes are fully documented below.

Renamed Calls

Transparent

The following functions have received simple renamings, which should be transparent from the META_REGCMD and META_REGCVAR macros.

• RegisterConCmdBase -> RegisterConCommandBase
• UnregisterConCmdBase -> UnregisterConCommandBase

Breaking

The following functions have received simple renamings, however, old code will be affected.

• pGlobals() -> GetCClobals
• engineFactory -> GetEngineFactory
• serverFactory -> GetServerFactory
• physicsFactory -> GetPhysicsFactory
• fileSystemFactory -> GetFileSystemFactory

For example, GET_V_IFACE_CURRENT would change from this:

GET_V_IFACE_CURRENT(engineFactory, engine, IVEngineServer, INTERFACEVERSION_VENGINESERVER);

To this:

GET_V_IFACE_CURRENT(GetEngineFactory, engine, IVEngineServer, INTERFACEVERSION_VENGINESERVER);

Removed Calls

A few API calls have been completely removed.

• RemotePrintingAvailable() - Unused, no purpose.
• GetCvarBaseAccessor() - Unused, no purpose.
• SetLastMetaReturn() - Did nothing.
• GetLastMetaReturn() - Did nothing.

Changed Calls

• IPluginManager::Query() and IPluginManager::QueryHandle() now store return values using optional pointers instead of references. This change was requested by a few people.

SourceHook has many new changes, the greatest of which is "global hooks," which can hook a function on any number of instances of that derived class. See SourceHook Development for more information.
