如上图，当showPercent调到0时还有一块是亮的，其余的到1都是正常的

//定义
private int segements = 100;
private float showPercent = 1.0f;

protected override void OnPopulateMesh(VertexHelper toFill)
{
  int realSegement = (int)(showPercent * segements); 
  //颜色处理部分
  UIVertex origin = new UIVertex();
  origin.color = new Color32(60, 60, 60, 225);

  int vertexCount = realSegement + 1;
  for (int i = 0; i < segements + 1; i++)
  {
     UIVertex vertexTemp = new UIVertex();
     if (i < vertexCount) 
     {
        vertexTemp.color = color;
     }
     else
     {
        vertexTemp.color = new Color32(60, 60, 60, 225);
     }
  }
  //画图部分
  int id = 1;
  for (int i = 0; i < segements; i++) 
  {
     toFill.AddTriangle(id, 0, id + 1);
     id++;
  }
}

找了一天了没找到原因，辛苦老师帮忙看看
