Unity UGUI錨點快速定位（自適應）

1.編輯器腳本需要放到Editor文件夾下面

簡單操作,快速讓錨點分布在組件四個頂點

選中組件(可以單選,可以多選)   點擊Tools/自適應錨點

 

 

 代碼如下:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;

public class AnchorController 
{
    [MenuItem("Tools/自適應錨點")]
    private static void SelectionAnchor()
    {
        GameObject[] objs = Selection.gameObjects;
        for (int i = 0; i < objs.Length; i++)
        {
            if (objs[i].GetComponent<RectTransform>() == null)
                continue;
            AnchorCon(objs[i]);
        }
    }

    private static void AnchorCon(GameObject obj)
    {
        //位置信息
        Vector3 partentPos = obj.transform.parent.position;
        Vector3 localPos = obj.transform.position;
        //------獲取rectTransform----
        RectTransform partentRect = obj.transform.parent.GetComponent<RectTransform>();
        RectTransform localRect = obj.GetComponent<RectTransform>();
        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:(納悶的一筆)

在預設物里面,用上面工具自適應之后保存,換一個預設物,在重新進剛剛的預設物里面,發現剛剛預設物的錨點跟沒應用之前是一樣的

最后解決辦法

先取消自動保存(AutoSave),然后隨便點擊一個組件的錨點,用鼠標拖動一下,再用上面的錨點工具應用錨點,最后勾上自動保存,在切換一下預設物回來,發現錨點應用成功

比手動拖要快多了

 

如果喜歡,請點個贊吧,感謝
