It's quite obvious. These are global variables:

pawn Код:

new PlayerBar:BarHungry;
new PlayerBar:BarSleep;
new PlayerBar:BarDefecate;

Make them arrays like these textdraws:

pawn Код:

new Text:SleepBar[MAX_PLAYERS];
new Text:HungryBar[MAX_PLAYERS];
new PlayerText:DefecateBar[MAX_PLAYERS];

That will make them per-player. I'm pretty sure you're supposed to create player bars (haven't used the include in a while) in the script init. Basically your problem is that you're replacing the index stored in the global variables every time a player connects.
