これは宿題です。Work 19 5/16 は課題です http://sites.stuycs.org/home/courses/ml2x/dyrland-weaver/work
メインメソッドを必要としないプログラム処理でこれを実行しています。
ブロブが私たちに与えられました。BlobRunner を独自に作成する必要がありました。私のコードが想定どおりに動作しない理由についてのアドバイスをいただければ幸いです。最初のファイル

The trickiest part of setup is to make
the screen an appropriate size for the
grid of blobs. The grid should be just
big enough to contain all of the blobs.

The main purpose of draw is to go through
the array of blobs and display each.

/*=====================================
Populate the array of blobs.
You can use any values for radius, number of sides
and wobble factor that you'd like, but you must
use x and y coordinates that ensure the blobs
are drawn in a grid without overlaping each other.
Your code should work for any reasonable value
of population (i.e. something that would fit on a
normal monitor).
