// Updated 7/22/2011 by Zunath
// Added Linux support for the REO module. There is no OnPlayerLeaving event in the Linux version of NWNX_Funcs
// so instead, we have to use Letoscript to make the changes. The PC's BodyBag value is used to store this info.
// This set up isn't applicable to all servers since most high level characters have massive amounts of HP and
// the BodyBag field only holds up to 116 HP. But for a server like REO, this should do just fine.
// Windows support remains to be used, too.

// Linux requires the LetoScript pluging and the NWNX_Funcs plugin.
// Windows only requires the NWNX_Funcs plugin.

//#include "nwnx_funcs_l"
#include "inc_mysql_tables"
#include "inc_system_const"

// Windows: This is fired on the OnPlayerLeaving event provided by NWNX_Funcs
// Linux: This is fired on the OnClientExit event.
// Will store the PC's current HP either on their database item (Windows) or on the BodyBag slot of the .bic file.
