我正在使用Kik API创建机器人。应该发生什么，就是当我输入！hangman时，游戏初始化。 hangman布尔值执行此操作，然后变为非活动状态。然后，人们可以使用！hangman LETTER来猜测这个词。很简单。然而，有一个奇怪的错误。第一次！使用hangman，它正常工作。然而，第二次，代码崩溃，声称状态和不正确的未定义，即使我确实定义了它们。任何帮助表示赞赏！

答案 0 :(得分：0)
首先，无需在;之后将}放在if语句之后。
其次，它们第二次没有被定义的原因是因为你在bot.onMessage函数中定义它们使它们成为局部函数，因此它们在函数完成时被销毁。相反，你应该在开头全局定义它们，如下所示：
var hangmanIsActive = false;
var hangmanBootup = true;
// Define them up here instead
var triesleft = "Tries left: "
var inttriesleft = 10
var alphabet = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s",
"t", "u", "v", "w", "x", "y", "z"];
var stage0 = triesleft + inttriesleft;
var stage1 = "\n"
"\n"
"\n"
" " + triesleft + {} + "\n"
"\n"
"\n"
"\n"
"_|___ \n";
var stage2 = "\n"
" |\n"
" |\n"
" | " + triesleft + {} + "\n"
" |\n"
" | \n"
" |\n"
"_|___ \n";
var stage3 = " _______\n"
" |/\n"
" |\n"
" | " + triesleft + {} + "\n"
" |\n"
" |\n"
" |\n"
"_|___ \n";
var stage4 = " _______\n"
" |/ |\n"
" |\n"

" |\n"

每次更改变量时，您似乎都在使用var，但只有在定义它们时才应该使用它。无需始终使用var：）
