Question

我想要实现的是而播放器按住鼠标按钮

在图块上（任何网格元素，与玩家完全或水平对齐），玩家将朝向该图块移动，可能的方向是左，右，上，下。

目前我的代码在按下鼠标按钮时不起作用，我认为它与光线投射有关。

我想要实现的第二件事是，当玩家在网格中移动时，如果玩家决定改变方向，他将能够，无论是否正好相反，或者他是否决定突然转弯左/右

（我设法在不使用isMoving布尔条件的情况下实现了它，只是在相反的方向，但是我添加了它，因为当玩家在移动时点击它会减慢他的速度）

现在移动时移动没有变化。

不确定您正在使用瓷砖和光线投射做什么，但这是我如何做到的。为格式化道歉，这就是我的工作方式。

编辑：好的，鉴于你说'网格'运动，我认为瓷砖彼此是等距的。 GetMouseButtonDown也改为GetMouseButton。这意味着每次更新都会拍摄一条光线，您可能希望这些更新能够提高效率。
