在过去的几天里，我一直在使用Arduino的TFT显示器为Arduino Esplora进行Pong游戏。游戏中的所有内容都有效，除非当玩家得分时，球从其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（或被覆盖会更好但是重新出现在中心。我已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何处。目标检测从第161行到第187行。

答案 0 :(得分：0)

因此，按照@ PaulOgilvie的想法，我使用以下代码解决了问题：

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，在整个事物的顶部绘制一个大的黑色矩形。
