[英]Not sure why this short processing assignment isn't working
这是一项家庭作业。 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main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到它应该被理解的任何建议。 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;}
}
第二个文件Blob
/*=====================================
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
====================================*/
class Blob {
int numSides;
int rad;
float x;
float y;
int xFactor;
int yFactor;
Blob(float cx, float cy, int sides, int r, int xf, int yf ) {
x = cx;
y = cy;
numSides = sides;
rad = r;
xFactor = xf;
yFactor = yf;
}
void display() {
float nx;
float ny;
int rx, ry;
float sy;
strokeWeight(1);
beginShape();
for( float t = 0; t <= 1; t+=( 1.0/numSides ) ) {
/*
"wobble" effect is created by adding a random number to each
x and y coordinate. The larger the x and y factors, the higher
the possible wobble value could be
*/
rx = (int)random(xFactor);
ry = (int)random(yFactor);
nx = rad * cos( 2 * PI * t ) + x + rx;
ny = rad * sin( 2 * PI * t ) + y + ry;
vertex(nx, ny);
}
endShape();
}
}
您的代码运行,因此它正在执行您要求它执行的操作,仅此而已。
我让我的猫检查出来然而她就是这样,“那个人在循环的每次传递中重新初始化他的变量,他永远不会得到那样的blob网格。告诉他从移动float y = 1; float x = 1;
开始float y = 1; float x = 1;
在两个for
循环的边界之外的populate()
中,从那里开始调试。“
然后她转过身来,她拍了拍她。
