 Hello,

``````    I am Brian Washechek, a 28 year old student at Casper College. Please look at this code! It's from Force Disruptor 2,
``````

a sequel to a game i wrote a long, long time ago ( i’m thinking like 7 years). I’ll keep on attempting to write code
for this if you would take a look tese couple of lines of code! This is a sequel to Force Disruptor (the original), that got lost a long time ago. Seriously, Thank you for the help! ( I don’t understand what it wants for the nadas).
