程序员必知：UnityUGUI锚点快速定位（自适应）

1.编辑器脚本需要放到Editor文件夹下面

简单操作,快速让锚点分布在组件四个顶点

选中组件(可以单选,可以多选) 点击Tools/自适应锚点

代码如下:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEditor;

public class AnchorController

{

【MenuItem("Tools/自适应锚点")】

private static void SelectionAnchor()

{

GameObject【】 objs = Selection.gameObjects;

for (int i = 0; i < objs.Length; i++)

{

if (objs【i】.GetComponent() == null)

continue;

AnchorCon(objs【i】);

}//代码效果参考：http://www.ezhiqi.com/zx/art_22.html

}//代码效果参考：http://www.ezhiqi.com/bx/art_1905.html

private static void AnchorCon(GameObject obj)

{

//位置信息

Vector3 partentPos = obj.transform.parent.position;

Vector3 localPos = obj.transform.position;

//--获取rectTransform

RectTransform partentRect = obj.transform.parent.GetComponent();

RectTransform localRect = obj.GetComponent();

float partentWidth = partentRect.rect.width;

float partentHeight = partentRect.rect.height;

float localWidth = localRect.rect.width 0.5f;

float localHeight = localRect.rect.height 0.5f;

//-位移差--

float offX = localPos.x - partentPos.x;

float offY = localPos.y - partentPos.y;

float rateW = offX / partentWidth;

float rateH = offY / partentHeight;

localRect.anchorMax = localRect.anchorMin = new Vector2(0.5f + rateW, 0.5f + rateH);

localRect.anchoredPosition = Vector2.zero;

partentHeight = partentHeight 0.5f;

partentWidth = partentWidth 0.5f;

float rateX = (localWidth / partentWidth) 0.5f;

float rateY = (localHeight / partentHeight) 0.5f;

localRect.anchorMax = new Vector2(localRect.anchorMax.x + rateX, localRect.anchorMax.y + rateY);

localRect.anchorMin = new Vector2(localRect.anchorMin.x - rateX, localRect.anchorMin.y - rateY);

localRect.offsetMax = localRect.offsetMin = Vector2.zero;

}//代码效果参考：http://www.ezhiqi.com/bx/art_3895.html

}

踩的坑:(纳闷的一笔)

在预设物里面,用上面工具自适应之后保存,换一个预设物,在重新进刚刚的预设物里面,发现刚刚预设物的锚点跟没应用之前是一样的

最后解决办法

先取消自动保存(AutoSave),然后随便点击一个组件的锚点,用鼠标拖动一下,再用上面的锚点工具应用锚点,最后勾上自动保存,在切换一下预设物回来,发现锚点应用成功

比手动拖要快多了
