Take your onCreated function and move it to the serverside. Also for important flags like that, regardless of the fact that they are clientr. it' a good idea to base64encode them when you're finished with testing.

For checking if a player will die:

temp.dmg = 5; //replace 5 with desired damage
if ( clientr.hp - temp.dmg <= 0 ) //If this is true the player will die.
clientr.hp -= temp.dmg;
