1. Leap Motion

import de.voidplus.leapmotion.*;
LeapMotion leap;
float handX=0, handY=0;
PVector [] coins=new PVector[10];
void setup() {
  size(500, 500);
  leap = new LeapMotion(this);
  for (int i=0; i<10; i++) coins[i]=new PVector( random(500), -random(100));
}
int score=0, life=10, speed=2;
int state=0;//state 0:playing, 1:gameOver, 2:showScoreBoard

    handX=hand.getPosition().x;
    handY=hand.getPosition().y;
  }

    for (int i=0; i<allScore.length; i++) {
      fill(255, 0, 0);
      textSize(30);

    }

      coins[i].y=-random(100);
    }
    if (dist(mouseX, mouseY, coins[i].x, coins[i].y)<30) {
      score+=100;
      coins[i].y=-random(100);
    }
  }
  fill(255);
  ellipse(handX, handY, 30, 30);
  fill(255, 0, 0);
  textSize(30);
  text("Score:"+score +"Life:"+life, 200, 200);
}

2. 檔案讀取、寫檔

//String [] names ={"AAA","BBB","CCC"};
//saveStrings( "myClassName.txt", names);

String lines[] = loadStrings("https://processing.org");
println("there are "+ lines.length + " lines");
for (int i=0 ; i < lines.length ; i++){
  println(lines[i]);
}

3. 排名
4. ArrayList 與資料結構

void setup() {
  size(600, 600);
  background(255);
}
void draw() {
  strokeWeight(20);
  stroke(0,0,200);
  if (mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);
}
int number = 0;
void keyPressed() {
  save("now.png");
  save("now" + number + ".png");
  number++;
}

Result：
now0.png、now1.png、now2.png

void setup() {

  size(600, 600);

  background(255);

}

void draw() {

  strokeWeight(20);

  stroke(0,0,200);

  if (mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);

}

void keyPressed() {

  saveFrame();

}

Result：

screen-1333.tif

5. 接金幣

PVector [] coins = new PVector[10];

void setup(){

  size(500,500);

  for (int i=0; i<10; i++){

    coins[i] = new PVector(random(500), -random(100)); 

  }

}

int score=0;

void draw(){

  background(255);

  for (int i=0;i<10;i++){

    fill(255,255,0); ellipse(coins[i].x, coins[i].y, 30, 30);

    coins[i].y+=2;

    if(coins[i].y>530) coins[i].y=-random(100);

    if(dist(mouseX, mouseY, coins[i].x, coins[i].y)<30){

      score+=100; coins[i].y = -random(100);

    }

  }

  fill(255,0,0); textSize(30); text("score:"+score, 200,200);

}
