Unity 写转盘

• 简单思路就是，每个圆形在前一个扇形的基础上，进行一个旋转，然后设置自己的fillCount

float allWeight = 0;

        var angle = 360f / element.Count;
        float angle = 0;
        int index = 0;
        foreach (var item in element)
        {
            var obj = GameObject.Instantiate<Image>(ImagePrefab, HandPoint);
            obj.gameObject.SetActive(true);
            obj.transform.localEulerAngles = new Vector3(0, 0, -angle);
            obj.fillAmount = (float)item.Weight / allWeight;
            angle += obj.fillAmount * 360f;
            obj.color = index % 2 == 0 ? Color.yellow : Color.green;
            index++;
        }
