[Feature Request] [CS 1.6] CVAR for allowing Server-Side Weapon Prediction

[Maxi605]

Implement a server-side cvar to allow the server to work if a client is using Server-Side weapon prediction (cl_lw 0). Since it seems that the whole CS 1.6 Community used to (Used to since they moved to CS:GO) considered cl_lw 0 to be a "Ilegal Command".

That's already possible by using this engine function:

halflife/engine/eiface.h

Line 245 in c7240b9

int (*pfnCanSkipPlayer) ( const edict_t *player );

The function returns whether the player's cl_lw setting is non-zero.

The server already uses this to determine whether a client is using client predicted weapons and skips sending weapon animation updates if so:

halflife/dlls/weapons.cpp

Lines 866 to 884 in c7240b9

	void CBasePlayerWeapon::SendWeaponAnim( int iAnim, int skiplocal, int body )
	{
	if ( UseDecrement() )
	skiplocal = 1;
	else
	skiplocal = 0;
	m_pPlayer->pev->weaponanim = iAnim;
	#if defined( CLIENT_WEAPONS )
	if ( skiplocal && ENGINE_CANSKIP( m_pPlayer->edict() ) )
	return;
	#endif
	MESSAGE_BEGIN( MSG_ONE, SVC_WEAPONANIM, NULL, m_pPlayer->pev );
	WRITE_BYTE( iAnim ); // sequence number
	WRITE_BYTE( pev->body ); // weaponmodel bodygroup.
	MESSAGE_END();
	}

ENGINE_CANSKIP is a macro that resolves to that function:

halflife/dlls/enginecallback.h

Line 142 in c7240b9

#define ENGINE_CANSKIP ( *g_engfuncs.pfnCanSkipPlayer )
