Sleep in tent regen blood simplified

[W4lly]

bloodAmount = 1000;

while {true} do
{
   if(r_player_blood > 12000) then {
        r_player_blood = 12000;
    } else {
       sleep 2;
	   if(s_player_sleep != -1) then {
       r_player_blood = r_player_blood + bloodAmount;
      };
 };
};

I have little knowledge of code .... 

try mod this (i put simply condition if players sleep)  extract from Krixes script,

works fine,

simply regen blood when sleep in tent ,

but it is correct or it may cause problems?
