javascript - Vue.js战斗-确认框覆盖重置功能

我目前正在通过Udemy的Vue.js教程进行工作。我已经到了您要制作战斗网络应用程序游戏的部分。完成之后，我决定练习重构，并遇到了这个错误。

当您单击攻击按钮，然后出现确认框询问您是否要再次玩游戏时，似乎在我的日志数组中添加了一个额外的项目，而不是完全重置游戏。

我怀疑这与过快按下攻击按钮有关，然后在运行addToLog（）之前出现确认框，然后再运行它。

否则可能是我的错误代码。大声笑

请注意，我知道单击确认框上的“取消”也会出现一些错误。

最佳答案

您的attack（和specialAttack）功能会同时攻击两个玩家：

    attack: function() {
        this.attackController('player', 10, 3);
        this.attackController('computer', 10, 3);
    },


当前，它正在检查每个attackController调用是否获胜。因此，当第一个攻击者（player）获胜时，游戏将重置，第二个玩家进行攻击。

因此，我的建议是将checkWin从attackController移到attack函数中：

    attack: function() {
        this.attackController('player', 10, 3);
        this.attackController('computer', 10, 3);
        this.checkWin();
    },


与specialAttack相同。

代码/ JSFiddle：https://jsfiddle.net/acdcjunior/wwc1xnyc/10/



请注意，当玩家获胜时，在上面的代码中，即使游戏结束了，计算机仍将“反击”。如果您想终止该操作，请在游戏结束后让checkWin返回：

    checkWin: function() {
        if (this.computerHealth <= 0) {
            this.alertBox('YOU WIN! New Game?');
            return true;
        } else if (this.playerHealth <= 0) {
            this.alertBox('LOSER!!! New Game?');
            return true;
        }
        return false;
    },


并将if添加到attack（和specialAttack）：

    attack: function() {
        this.attackController('player', 10, 3);
        if (this.checkWin()) return;
        this.attackController('computer', 10, 3);
        this.checkWin();
    },
