RectTransform.GetLocalCorners

切换到手册
public void GetLocalCorners (Vector3[] fourCornersArray);

参数

fourCornersArray 将各个角填充到其中的数组。

描述

获取计算的矩形在其 Transform 的本地空间中的各个角。

Each corner provides it's local space value. The returned array of 4 vertices is clockwise. It starts bottom left and rotates to top left, then top right, and finally bottom left. Note that bottom left, for example, is an (x, y, z) vector with x being left and y being bottom.

注意:如果 RectTransform 在 Z 中旋转,则 GetWorldCorners 的尺寸 不会更改。

using UnityEngine;

// GetLocalCorners(): // Rotate the local corners and display // the corner values.

public class ExampleClass : MonoBehaviour { RectTransform rt;

void Start() { rt = GetComponent<RectTransform>(); DisplayLocalCorners(); }

void DisplayLocalCorners() { Vector3[] v = new Vector3[4];

rt.rotation = Quaternion.AngleAxis(45, Vector3.forward); rt.GetLocalCorners(v);

Debug.Log("Local Corners"); for (var i = 0; i < 4; i++) { Debug.Log("Local Corner " + i + " : " + v[i]); } } }
