如何在与圆的加工中创建积分系统？

Question

因此，目标是每次锤子或水桶落下时添加一个黑色圆圈而不击中人，然后每次人进门时添加4个圆圈，当第一行圆圈被填满时，它将进入第二行，直到整个屏幕被填满，然后重新设置。而且，随着人被锤子或水桶击中，会出现一整排的红圈。我不知道该怎么做，谢谢。

基本上，您需要一个变量来表示点/圈的数量:points。圆圈本身应该在void循环中绘制，也许有两个for循环（见下文）。

此外，您还需要定义哪些圆圈应该是红色的。在下面的示例中，我使用了一个布尔数组，它为每个圆圈定义了是否应该是红色的。因此，如果第一个圆圈必须是红色的，则必须将redpoint[0]设置为true······

int i=0;
for(int y=10; y<height-10; y+=20) {
  for(int x=10; x<width-10; x+=20) {
    if(redPoint[i] == true) {
      fill(255,0,0);
    } else {
      fill(0);
    }
    if(i<points) {
      ellipse(x,y,15,15);
    }
    i++;
  }
}
