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;

}
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
如果喜欢,请点个赞吧,感谢
