需要幫助制作益智游戲

Question

我正在使用Perlenspiel制作益智游戲，並將Javascript與Sublime Text結合使用。 該游戲是關於玩家控制蝸牛的，它留下了玩家無法通過的綠色泥渣。 目標是用綠色粘液覆蓋白色珠子區域。 我已經完成了大部分游戲設置，我只需要幫助弄清楚如何用綠色粘液覆蓋該區域后如何結束游戲並加載下一個關卡。

我是使用Javascript和Perlenspiel的新手，但不確定如何使它工作。

// Put your global variables after this line
var GRIDWIDTH, GRIDHEIGHT;

Answer 1

盡管由於多種原因這是錯誤的方法，但一個簡單的解決方案是遍歷PS.data的x和y所有值，並檢查是否已將蝸牛的當前位置以外的每個坐標設置為"wall" 。

function boardCovered() {
  for(var x = 0; x < 10; x++) {
    for(var y = 0; y < 10; y++) {
      if(PS.data(x, y) != "wall")  //This is not the correct check - just an example. You need to figure this part out
        return false;
    }
  }
  return true;
}

我對Perienspiel一無所知，但這會迭代您的數據結構並為您提供正確的結果。
