這段時(shí)間工作比較空閑，想做個(gè)抽獎(jiǎng)系統(tǒng)，發(fā)現(xiàn)網(wǎng)上的抽獎(jiǎng)系統(tǒng)看不懂，然后自己做了一個(gè)可以隨意定義獎(jiǎng)品概率，不管什么時(shí)候停下來指針最終都會(huì)轉(zhuǎn)到指定的獎(jiǎng)品哪。
專注于為中小企業(yè)提供成都做網(wǎng)站、成都網(wǎng)站建設(shè)服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)方正免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了超過千家企業(yè)的穩(wěn)健成長，幫助中小企業(yè)通過網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。
廢話不多說，動(dòng)手一步一步來。
這個(gè)抽獎(jiǎng)系統(tǒng)就使用了兩張圖片，一個(gè)指針，一個(gè)圓形的圖片。
然后做一個(gè)預(yù)制體，圖片就是圓形圖片，image type選擇filled,fill amount控制這個(gè)圖片的面積大小，同時(shí)也是該圖片的概率，Text組件是該獎(jiǎng)品的名稱。
再接下來就做一下界面布局的工作
Bg就是那個(gè)灰色的圖片，Rotate是個(gè)空物體，用來掛在腳本的（DialRotate.cs和Slot.cs），cloneParent也是個(gè)空物體，作為預(yù)制體的父物體，要注意的是cloneParent中心那個(gè)藍(lán)色的圓圈要和Rotate的藍(lán)色的圈的位置一致，界面布局工作完成。
接下來到代碼了，Slot.cs腳本，一開始會(huì)實(shí)例化獎(jiǎng)品，K鍵和L鍵可以隨意修改獎(jiǎng)品名稱，概率（這里概率做了限制，需要使用的自己修改一下代碼即可），空格鍵會(huì)隨機(jī)拋出物品，并且開始旋轉(zhuǎn)，鼠標(biāo)右鍵是停止轉(zhuǎn)動(dòng)（想什么時(shí)候停下來都行，最后都會(huì)得到所拋出的物體）DialRotate.cs腳本用于處理旋轉(zhuǎn)的。這兩個(gè)腳本涉及到一些數(shù)學(xué)計(jì)算，慢慢理解即可。
以下是這個(gè)工程的腳本，需要的話直接復(fù)制黏貼即可使用
