陣列小練習

ArrayListPractice陣列小練習

{ }ArrayList

If you got this…如果你懂這個的話…

Think of How?想想看怎麼做這個 ?

First, you might

think in this way(Directly)

Probably I (Gary) am stupid

你可能會先這樣做又或許只有我這麼笨

import peasy.test.*;import peasy.org.apache.commons.math.*;import peasy.*;import peasy.org.apache.commons.math.geometry.*;PeasyCam cam;

void setup(){size(1000,1000,P3D);cam = new PeasyCam(this,0,0,0,1000);}

void draw(){background(0); for(int i =0; i<500; i+=50){ for(int j=0; j<500; j+=50){ fill(map(i,0,500,0,255),map(j,0,500,0,255),random(100,255)); pushMatrix(); translate(i,j,0); box(30,30,random(500)); popMatrix(); } }}

NOTHINGHAPPENS???!!!

If you like it this way, it’s also fine

如果你喜歡這樣也可以

Problem 01:Keep updating, not static.

Problem 02:The height extend in both sides

一直抖一直抖

高度往兩邊長

Now we need

ArrayList所以我們需要ArrayList

import peasy.test.*;import peasy.org.apache.commons.math.*;import peasy.*;import peasy.org.apache.commons.math.geometry.*;PeasyCam cam;

ArrayList randomH;

void setup(){size(1000,1000,P3D);cam = new PeasyCam(this,0,0,0,1000);randomH = new ArrayList();

for(int i =0; i<500; i+=50){ for(int j=0; j<500; j=j+50){ PVector h = new PVector(i,j,random(0,300)); randomH.add(h); } }}

void draw(){background(0);for(int i =0; i<randomH.size();i++){ PVector nH = (PVector)randomH.get(i); pushMatrix(); fill(map(nH.x,0,500,0,255),map(nH.y,0,500,0,255),map(nH.z,0,500,0,255)); translate(nH.x,nH.y,nH.z/2); box(30,30,nH.z); popMatrix(); }}

Create an ArrayList

Declare the ArrayList

Put stuffs inside

Call them out

Draw boxesFix the double sides problem

創造一個 ArrayList

宣告一個 ArrayList

在 ArrayList裡面放入東西

把他們取出來呈現

畫方盒解決往兩邊延長的問題

DONE!

完成
