Code (JavaScript):

1. #pragma strict
2. var curHp : float = 100.0;
3. var maxHp : int = 100;
4. var currentThirst : float = 100.0;

Stop asking for "help fast". It's annoying.

Clearly state what the problem is (ie - what is not working).

 

So you know where the problem is? What is your question anyway? You don't know how to write the code?

 

well i don't really know how to make 2 or 3 seconds where the enemy can't attack

 

it works but the enemy just drains my health
