连接四 - 找到获胜的处理(Java)

标签: java object for-loop processing

我正在使用Processing(Java)构建一个connect 4游戏,并且在尝试寻找获胜者时已经开始了。我发布的代码可能无论如何告诉我为什么这不起作用?或者我将如何补救它。

非常感谢任何帮助。

  if (whooseWon() == true) {
    text = loadFont("Tahoma-Bold-50.vlw");
    textFont(text, 50);
    fill(255, 0, 0);
    game = false;
    if (whoWon == 1) {
      text("Red Wins!", width/4, height/4);

你让人们很难帮助你。不要在巨幅草图中发布断开连接的片段,而是尝试创建MCVE。这通常涉及从空白草图开始并且仅添加足够的代码来重复该问题,而没有任何与其没有直接关系的额外内容。我们应该能够将代码复制并粘贴到我们自己的编辑器中,点击运行,并看到与您相同的东西。否则我们都只是在猜测。您通常会在创建MCVE的过程中解决您的问题!

话虽如此,我可以帮助您尝试调试您的问题。你说你得到了ArrayIndexOutOfBounds例外。错误在哪一行?我不是那么问你所以告诉我。我问这是因为这是你应该问自己的第一个问题。

当你将它缩小到一个特定的行时,你需要回溯以确切知道发生了什么。正在访问哪些索引?数组有多少个索引?你们两者之间存在不匹配,导致你的问题。

使用println()函数打印出可能属于此值的每个值。这至少是ij个变量,以及rowcolumnspiece.lengthpiece[yourIndexHere].length

然后逐行浏览您的代码,直到您完全了解它正在做什么为止。再一次,如果你从MCVE工作而不是试图解决一大堆问题,你会有更好的运气。然后,如果您遇到困难,您可以使用该MCVE发布一个新问题,我们将更容易为您提供帮助。祝你好运。
