Arduino LCD Space 入侵者

Arduino LCD Space Invaders

这是一个需要帮助的arduino代码。我的代码有一个我无法弄清楚的错误。我需要帮助将外星人放入数组中。

这是问题代码---

#define ALIEN_COUNT 24
int yAliens[ALIEN_COUNT]={0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1,1};
int xAliens[ALIEN_COUNT] = {0,1,2,3,4,5,6,7,8,9,10,11,0,1,2,3,4,5,6,7,8,9,10,11};

//...

for(byte a=0; a<=24; a++){
  if(fire&&xb== xAliens[a] && yb == yAliens[a]){
   hitAlien = true;
   break;
  }
  if(a>=25){
    a=0;
  }
}
 if (hitAlien) {
    fire = false;            //bullet stops moving
    lcd.setCursor(xb, yb);   //the position of the alien
    lcd.print(" ");          //becomes blank
    lcd.setCursor(xb+1,yb);
    lcd.print(" ");
}

我已尝试简化我们的代码并解决您的问题 我不能测试它,所以我不能确定一切都很好 我使用 byte 而不是 int 来考虑内存占用 我去掉了time直接处理子弹位置 为了更容易理解,我删除了旧位置,更新位置并在新位置打印对象。
