我的鼠标点击有问题，这就是我的代码看起来的样子，我的问题是，当我点击某些内容时，它应该转到下一页并绘制其他一些内容，例如当我点击系统图标时它应该进入系统图片屏幕并绘制其行星，当我点击行星它应该在行星表面上，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。我在更新的开始和结束时使用了许多方法，例如两个鼠标状态，但没有一个工作。可以帮助我吗？

对于所有鼠标按钮事件，您应该跟踪上一个更新帧的状态，以便（在您的情况下）只有在鼠标按钮最初按下时才能触发菜单事件。因此，您可以使用以下内容代替if (mouse1.LeftButton == ButtonState.Pressed)：
if (mouse1.LeftButton == ButtonState.Pressed && prevMouse1.LeftButton != ButtonState.Pressed)
{
// ...
}
prevMouse1 = mouse1; // Update the state for the next frame.
我建议将此功能包装在自己的类中。
还要考虑用户界面当前标准的基于鼠标的行为是只有当光标位于控件上时按下鼠标按钮和时才会激活控件 - 并且仅鼠标释放后。
