2.1 布局

       void CreateItems(){var rewardLists = LuckyManager.Instance.CalculateRewardId(rewardDatas, Random.Range(4, 5));reward_data_list = reward_data_list ?? new List<RewardData>();reward_data_list.Clear();for (int i = 0; i < itemCount; i++){Transform item = null;if (i + 1 <= itemRoot.childCount){item = itemRoot.GetChild(i);}else{item = Instantiate(itemRoot.GetChild(0), itemRoot);}int rewardId = -1;foreach (var index in rewardLists){if (i == index){rewardId = index; break;}}var reward_img = item.Find("Icon").GetComponent<Image>();var reward_value = item.Find("Value").GetComponent<TextMeshProUGUI>();if (rewardId < 0){reward_img.gameObject.SetActive(false);reward_value.gameObject.SetActive(false);continue;}var reward_data = LuckyManager.Instance.GetDataById(rewardDatas, rewardId, out int wheel_index);reward_data_list.Add(reward_data);reward_img.sprite = itemImgs[reward_data.type - 1];reward_img.SetNativeSize();reward_value.text = string.Format("{0}", reward_data.amount);reward_img.gameObject.SetActive(true);reward_value.gameObject.SetActive(true);}}

2.2 操作逻辑

   protected internal override void OnInit(UIView view){base.OnInit(view);btnClose.onClick.AddListener(OnCloseEvent);}protected internal override void OnOpen(object userData){base.OnOpen(userData);eraseMask.Init(EraseComplete);rewardDatas = LuckyManager.Instance.GetDefaultScrathcCardData(itemCount);IsRolling = false;CreateItems();}
