這篇文章主要介紹了Unity之跑馬燈抽獎效果單抽與連抽，文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值，需要的朋友們下面隨著小編來一起學習學習吧
本文主要介紹了Unity之跑馬燈抽獎效果單抽與連抽，分享給大家，具體如下：
效果圖
單次抽獎效果
跳過動畫抽獎效果
三連抽抽獎效果
設(shè)計思路 點擊按鈕 ，根據(jù)需求(概率)計算本次抽獎獲得物品模擬轉(zhuǎn)動 (先加速后減速)， 一段時間后停止連抽的情況下等所有獎品動畫都表演完成才結(jié)束跳過動畫設(shè)計，有跳過時抽獎速度直接到最大，并進入可中獎 場景搭建
一個按鈕，一個組獎品放到一個父物體上。
獎品元素，有兩種狀態(tài)，一種旋轉(zhuǎn)狀態(tài)，一種中獎狀態(tài)。
