You ask for a random number

Then you your points by that random number, so if the random
subtracted from current hp is negative it will print that negative
when you ask it to print hp - mydmg.

So, you add another if hp <= 0, in addition to the if my mydmg>myhp,
then print 0, instead of hp - myd_mg
