Mesh-Clip分割_skybeauty_新浪博客

效果图如上，分割各种多边形图，具体操作是通过修改uv过滤显示，具体代码如下：

using System;
using UnityEngine;
using UnityEngine.UI;

public class MeshClipBase : MaskableGraphic, ILayoutElement, ICanvasRaycastFilter
{

    [SerializeField]
    Sprite m_Sprite;
    public Sprite sprite
    {
        get { return m_Sprite; }
        set
        {
            m_Sprite = value;
            SetAllDirty();
        }
    }

    [NonSerialized]
    Sprite m_OverrirdeSprite;

    public Sprite overrideSprite
    {
        get { return m_OverrirdeSprite==null?sprite:m_OverrirdeSprite; }
        set
        {
            m_OverrirdeSprite = value;
            SetAllDirty();
        }
    }

    public float alphaThreshold = 1;

    public override Texture mainTexture
    {
        get
        {
            if (overrideSprite != null)
            {
                return overrideSprite.texture;
            }
            else if (material != null && material.mainTexture != null)
            {
                return material.mainTexture;
            }
            else
            {
                return s_WhiteTexture;
            }
        }
    }

    public float pixelsPerUnit
    {
        get
        {
            float spritePixelsPerUnit = 100;
            float ref
