Day 23

Today i made the zombies have a collision kind of relationship between each other. Although... it freezes at times i say it is the best i can do at my level of knowledge. What i did today was i took off the Solid check box and replaced that with a collision code:
x = xprevious
y = yprevious

I don't know why this works, it just does. So i left it at that. Tomorrow i will see what i should do tomorrow.
