《unity3d游戲開發(fā)之IOS自定義游戲搖桿與飛機平滑的移動(》由會員上傳分享，免費在線閱讀，更多相關(guān)內(nèi)容在工程資料-天天文庫。
1、移動開發(fā)游戲中使用到的觸摸游戲搖桿在iPhone上是非常普遍的，畢竟是全觸摸屏手機，今天MOMO通過一個小例子和大家討論unity3D中如何自定義一個漂亮的全觸摸游戲搖桿。??出自狗刨學(xué)習(xí)網(wǎng)??????????值得高興的是，unity3d?游戲引擎的標準資源中已經(jīng)幫助我們封裝了一個游戲搖桿腳本，所以實現(xiàn)部分的代碼可以完全借助它的，具體調(diào)用需要我們自己來。????Joystick.js是官方提供的腳本，具體代碼如下，有興趣的朋友可以仔細研究研究，MOMO就不多說啦。哇咔咔～1.////////////////////////////////
