秀出分數的方法

fill(#FFE412); text("Score:"+score,100,50);

{

    int i=int (mouseY/100),j=int(mouseX/100);

 用滑鼠點圖片會消失

程式碼:

int [][]A={ {2,2,2,2},

            {0,1,1,1},

            {0,1,1,1},

            {2,2,2,2} };

PImage bird, pig;

void mousePressed()

{

  int i = int(mouseY/100);

  int j = int(mouseX/100);

  A[i][j]=0;

}

void setup()

{

    size(400,400);

    bird=loadImage("bird.png");

    pig =loadImage("pig.png");

}

{

  background(0);

  for(int i=0; i<4; i++)

      if(A[i][j]==2) image(pig, j*100, i*100,100,100);

    }

  }

}

陣列

     else fill(255,0,0);---------------------沒有就填紅色

在網路上找圖 再把圖拉到process

設定好圖片大小 就會有圖片了

再找一張去背的圖 在改一些程式碼

就能讓去背圖跟著滑鼠移動了

PImage(讀入圖檔)

視窗碰撞:

float x=250,y=200;

float vx=1.0,vy=4.5;

void setup(){

 size(500,400); 

}

void draw(){

 ellipse(x,y,10,10); 

 x+=vx;

 y+=vy;

 if(x>500|| x<0)vx=-vx;

 if(y>400|| y<0)vy=-vy;

}

彈弓彈射

float x=250,y=200;

float vx=0,vy=0;

void setup(){

 size(500,400); 

}

void draw(){

  if(mousePressed)line(mouseX,mouseY,x,y);

 ellipse(x,y,10,10); 

 ellipse(mouseX,mouseY,10,10);

 x+=vx;

桌面葉正聖老師所需檔案

processing-3.5.3

processing.exe

開始學習程式碼

setup

size(寬,高);

視窗大小

drawline(x1,y1,x2,y2);

rect(x,y,寬,高);

ellipse(x,y,寬,高);

color-

background(#RGB);

stroke(#RGB);

fill(#RGB);

or(R,G,B);

舉例:

點選畫面區塊，顯示點選顏色

PImage img;

color nowColor;

void setup() {

  size(300, 200);

  img=loadImage("cloud.png");

}

void draw() {

  image(img,0,0);

  fill(nowColor);

  rect(0,0,30,30);

}

void mouseMoved(){

  loadPixels();

  int now = width * mouseY + mouseX;

  nowColor = pixels[now];

}

for(int angle=0;angle<360;angle+=120)

{

    float angle2= radians(angle+mouseX);

    float x = 100+cos(angle2)*50;

    float y = 100+sin(angle2)*50;

    vertex(x,y);

}

endShape(CLOSE);

}

1hr=60min,1min=60sec,1sec=60ftames

frameCount:第幾個frame

角度有兩種:degree度(360度的世界)

sin()cos()用radions弧度/經度(PI世界)

切水果

Java的陣列 vs C陣列 float fruitX[10];
