Week9 錡洛誼上課筆記

1. 檔案讀取 寫檔
2. 排名
3. 實作：ArrayList 與資料結構
void setup()
{
  size(600, 600);
}

void draw() {
  if (mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);
}
int number = 0;
void keyPressed() {
  save("now_"+ number+".png");
  number++;
}

程式2: 以frame寫：

void setup()
{
  size(600, 600);
}

void draw() {
  if (mousePressed) line(mouseX, mouseY, pmouseX, pmouseY);
}
//int number = 0;
void keyPressed() {
  saveFrame();
  //save("now_"+ number+".png");
  //number++;
}

程式3: 使用processing api
//String [] names = {"AA","BB","CC"};
//saveStrings("myClassmateName",names);


String lines[] = loadStrings("myClassmateName.txt");
println("there are " + lines.length + " lines");
for (int i = 0 ; i < lines.length; i++) {
  println(lines[i]);
}  

程式3: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);
}

程式4: 結合記分板 跟 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, life=10, speed=2;

int state=0;//state 0:playing, 1:gameOver, 2:showScoreBoard

String [] allScore;

void draw() {

  if (state==2) {

    background(255, 255, 0);

    for (int i=0; i<allScore.length; i++) {

      fill(255, 0, 0); 

      textSize(30);

      text( allScore[i], 100, 200+i*50);

    }

    return ;

  } else if (state==1) {

    background(128); 

    speed=0;

    allScore = loadStrings("allScores.txt");

    if (mousePressed) state=2;

  } else 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+=speed;//!!!!!!

    if (coins[i].y>530) {

      coins[i].y=-random(100);

      life--;

      if (life<=0) state=1;

    }

    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 +"Life:"+life, 200, 200);

}
