如何使用鼠标右键而不是OnMouseDrag？

如何调整以下脚本以使用鼠标中键或鼠标右键而不是鼠标左键？该脚本目前使用OnMouseDown，OnMouseUp和OnMouseDrag。

Answer 1

OnMouseDown，OnMouseUp和OnMouseDrag仅用于左键单击。要通过右键单击实现，您需要做的是使用Input.GetMouseButtonDown(1)和Input.GetMouseButtonUp(1)来了解鼠标按钮的状态。

这样的事情：

bool dragging = false;
void Update()
{
    if(Input.GetMouseButtonDown(1))
    {
        yourOnMouseDownFunction();
        dragging = true;
    }
    if(Input.GetMouseButtonUp(1))
    {
        yourOnMouseUpFunction();
        dragging = false;
    }

    if(dragging )
    {
        yourOnMouseDragFunction();
    }
}

有更好的方法可以做到这一点，但它们需要更多的代码。
