这是一个家庭作业。工作 19 5/16 是作业 http://sites.stuycs.org/home/courses/ml2x/dyrland-weaver/work
我在程序处理中运行它，它不需要主要方法。
Blob 是给我们的。我们必须自己制作 BlobRunner。关于为什么我的代码没有做它应该做的任何建议将不胜感激。第一个文件 BlobRunner
int popSize = 4;
int wobble = 2;
int numSides = 4;
float rad = 100;
int radInt = (int) rad;
float a = sqrt(popSize);
int rootPop = (int) a;
Blob[][] blobs = new Blob[popSize/rootPop][rootPop];
/*=====================================
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.
====================================*/
void setup() {
size ((popSize/rootPop)*(2*(radInt+3)), rootPop*(2*(radInt+3)));
populate();
}
/*=====================================
The main purpose of draw is to go through
the array of blobs and display each.
====================================*/
void draw() {
int createdSoFar = 0;
for (int i = 0; i<rootPop; i++){
for (int j = 0; j<popSize/rootPop; j++){
if (createdSoFar < popSize){
blobs[j][i].display();
}
createdSoFar++;
}
}
}
/*=====================================
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).
====================================*/
void populate() {
for (int i = 0; i < rootPop; i++){
float y = 1;
for (int j = 0; j < (popSize/rootPop); j++){
float x = 1;
blobs[j][i] = new Blob (x*(rad+3), y*(rad+3), numSides, radInt, wobble, wobble);
x=x+2;}
y=y+2;}

/*=====================================
A Blob object is a regular polygon variant that
can have various features.
Instance Variables:
numSides: number of sides
rad: distance from the center of the polygon
to any vertext
x: x coordinate of the center
y: y coordinate of the center
xFactor: "wobble" foctor in the x direction
yFactor: "wobble" factor in the y direction
====================================*/
