x | 用于开始测量矩形的 X 值。 |
y | 用于开始测量矩形的 Y 值。 |
width | 矩形的宽度。 |
height | 矩形的高度。 |
创建一个新的矩形。
using UnityEngine;
public class RectExample : MonoBehaviour { void Start() { Rect rect = new Rect(0, 0, 10, 10);
// prints: (x:0, y:0, width:10, height:10) Debug.Log(rect); } }
注意:Rect 表示抽象矩形,可以用于各种情况。因此,Rect 没有明确的顶部、底部、左侧或右侧。例如,摄像机空间中的 Y 值从屏幕底部进行测量,但是编辑器 GUI 空间中的 Y 值从窗口顶部进行测量,因此 Rect 的 Y 值是其“顶部”还是“底部”因使用 Rect 值的位置而异。可以使用 Rect.min 和 Rect.max 引用各个角。
position | 矩形最小角的位置。 |
size | 矩形的宽度和高度。 |
根据给定的大小和位置,创建一个矩形。
在已使用 Vector2 值时,这种形式的构造函数会十分方便。
