Arduino 探索乒乓球游戏

Question

在过去的几天里，我一直在为 Arduino Esplora 使用 Arduino 的 TFT 显示器开发 Pong 游戏。游戏中的一切都有效，除了当玩家得分时球从它的最后位置被删除并重新出现在中心（应该如此），而当计算机得分时球不会被删除（或者覆盖会更好字），但重新出现在中心。我已经尝试对代码的这个区域进行一些更改但没有成功，特别是因为我不知道它来自哪里。目标检测从第 161 行到第 187 行。

正在发生的事情的可视化：

Answer 1

所以按照@PaulOgilvie 的想法，我用下面的代码解决了这个问题：

if (BPY >= 160 || BPY <= 0) {//Goal Detection
    if (BPY >= 160) {  
      playerScore = playerScore + 1;
    }
    else {
      computerScore = computerScore + 1;
    }
    DrawCourt(0);
    EsploraTFT.fillCircle(BPX, BPY, 7, ST7735_BLACK);
    EsploraTFT.fillRect(computerPaddle, 154, 32, 3, ST7735_GREEN);
    EsploraTFT.fillRect(1,0,126,15,ST7735_BLACK);
    EsploraTFT.fillRect(playerPaddle, 3, 32, 3, ST7735_GREEN);
    DisplayScore(playerScore, computerScore);
    BPX = 64;
    BPY = 80;
    EsploraTFT.fillCircle(BPX, BPY, 4, ST7735_GREEN);
    delay(3000);
    EsploraTFT.fillCircle(BPX, BPY, 7, ST7735_BLACK);
    byx = 80;
  }

基本上我只是做了一个解决方法，在整个东西的顶部画了一个黑色的大矩形。
