检测一定范围内的光标

Detecting cursor in a certain range

我正在尝试找出一种方法来检测光标在特定范围内的位置。这就是我正在寻找的东西:

if ('bla bla bla' && Input.mousePosition == (in between x1 and x2, in between y1. and y2))

这在unity中可行吗,因为我想不通:( 感谢您的帮助!

Vector2 mousePos = Input.mousePosition;

这个returns一个Vector2鼠标位置坐标xy。检查坐标为mousePos.xmousePos.y的点是否在x1x2范围内; y1y2,我们可以写成

if((mousePos.x >= x1 && mousePos.x <= x2) &&
   (mousePos.y >= y1 && mousePos.y <= y2))
{
    // do something
}

或者,

if(mousePos >= new Vector2(x1, y1) &&
   mousePos <= new Vector2(x2, y2))
{
    // do something
}

您也可以使用 Rect.Contains 来防止重复:

var InRect = new Rect(0, 0, Screen.width/2, Screen.height).Contains(Input.mousePosition);

UnityEngine.Debug.Log(InRect);
