Image.fillOrigin

描述

控制填充过程的原点。对于每种填充方法，值的意义不同。

应强制转换为适当的原点类型：Image.OriginHorizontal、Image.OriginVertical、Image.Origin90、Image.Origin180 或 [[Image.Origin360] depending on the Image.Fillmethod。

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

[RequireComponent(typeof(Image))]
public class ImageOriginCycle : MonoBehaviour
{
    void OnEnable()
    {
        Image image = GetComponent<Image>();
        string fillOriginName = "";

        switch ((Image.FillMethod)image.fillMethod)
        {
            case Image.FillMethod.Horizontal:
                fillOriginName = ((Image.OriginHorizontal)image.fillOrigin).ToString();
                break;
            case Image.FillMethod.Vertical:
                fillOriginName = ((Image.OriginVertical)image.fillOrigin).ToString();
                break;
            case Image.FillMethod.Radial90:

                fillOriginName = ((Image.Origin90)image.fillOrigin).ToString();
                break;
            case Image.FillMethod.Radial180:

                fillOriginName = ((Image.Origin180)image.fillOrigin).ToString();
                break;
            case Image.FillMethod.Radial360:
                fillOriginName = ((Image.Origin360)image.fillOrigin).ToString();
                break;
        }
        Debug.Log(string.Format("{0} is using {1} fill method with the origin on {2}", name, image.fillMethod, fillOriginName));
    }
}

注意：仅当 Image.type 设置为 Image.Type.Filled 时，这才会有效。
