public AddHealth(id){
    if (is_user_alive(id)) return 0;
    set_user_health(id, get_user_health(id) + (20*HealthLevel[id]));
    Refreshing[id] = false;
    return 1;
} 

public NeverEndingRegen(id){
    if (is_user_alive(id) && cs_get_user_team(id) == CS_TEAM_CT && !Refreshing[id]) return 0;
    
    set_user_health(id, get_user_health(id) + RegenLevel[id]);
    return 1;
