<Pressed to draw a octopus. Pressed Key to clean the screen>
This week, we learned Array, ArrayList , PVector and I used these new knowledge I learned to create a group of octopus. I used PVector to made the tentacles of octopus. I used several circles to compose its tentacles, put all circles in an ArrayList, and made them generated one by one when you click the mouse on the Screen, just like the octopus grow its tentacles.
I didn't write it very well, because when the mouse drag it, the program think the mouse still pressed it, and continue to generate octopus. That's not the things I suppose before, so I 'll just rewrite the code and hope it works in better way.
