鼠标点击问题
本文关键字：问题 鼠标 | 更新日期: 2023-09-27 18:01:34
我的鼠标点击有问题，这就是我的代码的样子，我的问题是，当我点击某个东西时，它应该会转到下一页并绘制其他一些东西，例如，当我单击系统图标时，它会转到系统图片屏幕并绘制其行星，当我再次单击行星时，它应在行星表面上，但不幸的是，如果行星坐标与系统相同，当我点击系统时，它会直接进入行星表面。我使用了很多方法，例如在Update的开头和结尾使用了两个mousestate，但都不起作用。有人能帮我吗？

对于所有鼠标按钮事件，您应该跟踪上一个更新帧的状态，这样(在您的情况下(只有在最初按下鼠标按钮时才能触发菜单事件。因此，您可以使用以下内容来代替if (mouse1.LeftButton == ButtonState.Pressed)：
if (mouse1.LeftButton == ButtonState.Pressed && prevMouse1.LeftButton != ButtonState.Pressed)
{
// ...
}
prevMouse1 = mouse1; // Update the state for the next frame.
我建议将此功能封装在自己的类中。
还要考虑的是，当前用户界面基于鼠标的标准行为是，只有当光标位于控件上时，同时按下和释放鼠标按钮，并且只有在释放后，控件才会被激活。
