 今日進度:

1.學習用PVector代替定義多個座標

2.學習應用PVector的座標

3.學習如何應用PVector製作憤怒鳥

4.makeuno回傳座標值

1.程式碼:

size(600,600);

PImage img=loadImage("img.jpg");

PVector user=new PVector(10,20,0);

PVector user2=new PVector(30,40,50);

image(img,0,0);

print("user's="+user.x);

println(" user2's="+user2.x);

執行結果:

2.程式碼:

PVector user;

void setup()

{

  size(600,600);

  user=new PVector(10, 20);

}

void draw()

{

  background(255);

  ellipse(user.x,user.y,20,20);

}

執行結果:

3.程式碼:

PVector user;

PVector Y,v=null;

void setup()

{

  size(600,600);

  user=new PVector(100, 300);

  Y= new PVector(100,300);

}

void draw()

{

  background(255);

  line(user.x,user.y,Y.x,Y.y);

  textSize(40);

  fill(255,0,0);text("Y",Y.x,Y.y);

  fill(255); ellipse(user.x,user.y,20,20);

  if(v!=null)

    user.add(v);

}

void mouseDragged()

{

  user.x=mouseX;

  user.y=mouseY;

}

void mouseReleased()

{

  PVector diff = PVector.sub(Y, user);

  v=diff.div(10);

}

執行結果:

4.程式碼:

void setup() 

{

  // put your setup code here, to run once:

  pinMode(2,INPUT_PULLUP);

  Serial.begin(9600);

}

void loop()

{

  // put your main code here, to run repeatedly:

  int x = analogRead(A0);

  int y = analogRead(A1);

  int sw = analogRead(2);

  Serial.write(x);

  Serial.write('+');

  Serial.write(y);

  Serial.write('+');

  Serial.write(sw);

  Serial.write('\n');

  delay(20);

}

執行結果:

5.makeuno程式碼:

void setup() 

{

  // put your setup code here, to run once:

  pinMode(2,INPUT_PULLUP);

  Serial.begin(9600);

}

void loop()

{

  // put your main code here, to run repeatedly:

  int x = analogRead(A0);

  int y = analogRead(A1);

  int sw = analogRead(2);

  Serial.write(x/4);

  Serial.write(y/4);

  Serial.write(sw);

  delay(20);

}

processing程式碼:

import processing.serial.*;

Serial myport;

void setup()

{

  size(256,256);

  myport = new Serial(this,"COM6",9600);

}

int ballX=0,ballY=0;

void draw()

{

  background(255);

  if(myport.available()>=3)

  {

    int x = myport.read();

    int y = myport.read();

    int sw = myport.read();

    ballX=x;

    ballY=y;

  }

  ellipse(ballX,ballY,10,10);

}

執行結果:

6.程式碼:

import processing.serial.*;

Serial myport;

PVector user;

PVector Y,v=null;

void setup()

{

  size(600,400);

  myport = new Serial(this,"COM6",9600);

  user = new PVector(100,300);

  Y = new PVector(100,300);

}

void draw()

{

  background(255);

  if(myport.available()>=3)

  {

    int x = myport.read();

    int y = myport.read();

    int sw = myport.read();

    user.x = 100+x-128;

    user.y = 900+y-128;

  }

  textSize(40);

  fill(255,0,0); text("Y",Y.x,Y.y);

  fill(255); ellipse(user.x,user.y,20,20);

   if(v!=null)

   {

    user.add(v);

    v.y+=9.8;

   }

}

執行結果:
