Porting Valve Server Plugins or Metamod:Source plugins to Left 4 Dead is not very difficult. This article explores some of the changes and how to simplify them.

Users of Metamod:Source must upgrade to Metamod:Source 1.7 and use the 1.6+ API (see [[MM:S API Differences]]).

As there is no official SDK yet, we've simply reverse engineered the new header files. These changes aren't guaranteed to be 100% correct and the SDK isn't complete for building mods -- just most plugins.

=Removals=
The <tt>IVEngineServer</tt> functions <tt>PEntityOfEntIndex</tt> and <tt>IndexOfEdict</tt> have been removed for faster code that can be inlined. An example of how to re-implement this (as Valve has not released a new SDK yet):

<pre>
inline int IndexOfEdict(const edict_t *pEdict)
{
return (int)(pEdict - gpGlobals->baseEdict);
}
inline edict_t *PEntityOfEntIndex(int iEntIndex)
{
if (iEntIndex >= 0 && iEntIndex < gpGlobals->maxEntities)
{
return (edict_t *)(gpGlobals->baseEdict + iEntIndex);
}
return NULL;
}
</pre>

=Annoyances=
The console will spew "VPK" warnings unless your file-backed KeyValues operations use relative paths instead of absolute paths.
