WEEK06,期中作業

第一節
和組員一起做期中作品，討論期中作品如何做
遊戲名稱:點球球遊戲
遊戲說明:當隨機一顆球出現時，請點選他，他會開始往下掉，如果掉到底部就輸了，點選他之後會分裂變小，最終遊戲沒有球在螢幕上，就輸了，點選到球就有分數，點到越小顆的球分數越高。
遊戲目的:訓練眼睛和手的反應速度。

第2節
開始寫程式碼

float [] ballX = new float [50];
float [] ballY = new float [50];
float [] ballVX = new float [50];
float [] ballVY = new float [50];
float [] ballR = new float [50];
int h = 800;
int w = 800;
int test = 0;
void setup() {
  size(h, w);
  ballX[0] =  400 ;
  ballY[0] =  150;
  ballVX[0] = 0 ;
  ballVY[0] = 0.5;
  ballR[0] = 300;
}
void draw() {
  background(255);
  noStroke();
  fill(0, 255, 255);
  for (int i = 0;i<50;i++) {    
    ellipse(ballX[i], ballY[i], ballR[i], ballR[i]);
    if (ballX[i] != 0) ballVY[i] +=0.2;
    ballX[i] += ballVX[i];
    ballY[i] += ballVY[i];
  }
}
void newball(int i) {
}

void mousePressed() {
  for (int i = 0;i<50;i++) {
    if (dist (ballX[i], ballY[i], mouseX, mouseY)<=(ballR[i]/2)) {
      ballX[i] = mouseX - ballR[i]/10;
      ballY[i] = ballY[i];
      ballVX[i] = -cos(random(PI/2));
      ballVY[i] = -ballVY[i];
      ballR[i] = ballR[i]*2/3;
      for (int j = 0 ; j < 50 ; j ++ ) {
        if (ballX[j] == 0.0 && ballY[j] == 0.0  ) {
          test ++ ;
        }
        if (test != 0) {
          ballX[j] = mouseX + ballR[i];
          ballY[j] = ballY[i];
          ballVX[j] = cos(random(PI/2)) ;
          ballVY[j] = ballVY[i];
          ballR[j] = ballR[i];
          test=0;
          break;
        }
      }
    }
  }

}

一開始出現的球

                                                             點選球後開始分裂
