Animation 通过单击移动更改子画面的Y轴

我是新来的，不熟悉编程。我已经找了一段时间了，虽然我找不到任何有助于解决这个问题的东西

我试图让我的精灵表在精灵表的不同行走帧之间循环，我用IsKeyDown很容易做到，但当涉及到使用鼠标在某处行走时，我花了一段时间才想出一个“糟糕”的解决方案：

if (destination.X > position.X)                
                currentFrame.Y = 6;
            if (destination.X > position.X && destination.Y >= position.Y + 35)
                currentFrame.Y = 7;
            if (destination.X > position.X && destination.Y <= position.Y - 35)
                currentFrame.Y = 5;

这算是可行的，但我想知道是否有更好的解决办法。 我想要的是能够在游戏屏幕上点击，并选择适当的精灵行，相对于精灵当前位置和目的地，使其以正确的方式设置动画

很抱歉，如果以前有人问过这个问题，但我在发布之前已经搜索了几个小时，没有发现任何东西。

我有点不清楚您到底在做什么。你只有两个精灵吗，一个左一个右？这是我在您当前代码中看到的所有内容，但您指的是动画。我将假设您有一整套精灵来设置行走动画，在这种情况下，我认为本教程将涵盖您需要的内容：

更具体地说，本教程第4部分：

基本上，您需要设置计时器来控制精灵动画，因为对于这种类型的鼠标移动，从单击鼠标到对象到达目标之间的移动没有更多的输入。因此，需要使用计时器来确定何时调用行走动画中的下一个精灵

或者，如果currentFrame=1，那么currentFrame=2，如果currentFrame=2，那么currentFrame=3，等等，您可以进一步详细说明您的if语句，但是如果您对图形或精灵从精灵表中拉出的方式进行更改，这将是混乱的，并且很难维护。它也很可能动画太快，而且你必须使用定时器来减慢它的速度。

我想我已经解决了。这是我的代码，希望格式正确。抱歉，如果我不打算回答我自己的问题，我想这可能会对其他人有所帮助：

是的，我不太确定该怎么说。我的精灵表是[9,8]，有8个运动方向和9帧动画。这是我的一个键盘；错过了5分钟的编辑规则，并改变了我的解释一点。是的，我不太确定该怎么说。我的精灵表是[9,8]，有8个运动方向和9帧动画。我试图找到的是，如果我点击我的精灵的北部，如何使我的精灵表更改为北部行，我让它在9个不同的精灵之间循环，只是不容易通过鼠标坐标更改精灵的行。我会查看链接并感谢您的回复。
