由于作者手頭上沒(méi)有現(xiàn)成的模型，所以我將在Unity3D 官網(wǎng)中下載官方提供的游戲DEMO 中的模型來(lái)使用。另外官方提供了很多Unity3D 游戲DEMO,與詳細(xì)的文檔?？梢詭椭覀儗W(xué)習(xí)Unity.有興趣的盆友可以去看看哈。

本章博文的目的是利用上一章介紹的游戲搖桿來(lái)控制人物模型的移動(dòng)，與行走動(dòng)畫的播放。
如上圖所示Create中的文件夾male中存放著模型動(dòng)畫與貼圖等，這個(gè)應(yīng)該是美術(shù)提供給我們的。然后將整個(gè)male用鼠標(biāo)拖動(dòng)到左側(cè)3D世界中，通過(guò)移動(dòng)，旋轉(zhuǎn)，縮放將人物模型放置在一個(gè)理想的位置。右側(cè)紅框內(nèi)設(shè)置模型動(dòng)畫的屬性。
Animation
idle1 該模型默認(rèn)動(dòng)畫名稱為idle1
Animations
size 該模型動(dòng)畫的數(shù)量
Element 該模型的動(dòng)畫名稱
Play Automatically 是否自動(dòng)播放
Animation Physics 是否設(shè)置該模型物理碰撞
Animation Only if Visable 是否設(shè)置該模型僅自己顯示
給該模型綁定一個(gè)腳本Controller.cs 用來(lái)接收搖桿返回的信息更新模型動(dòng)畫。

上一章介紹了javaScript腳本使用游戲搖桿的方法，本章MOMO告訴大家使用C＃腳本來(lái)使用游戲搖桿，上面我用 Controller.cs C＃腳本來(lái)接收系統(tǒng)提供的Joystick.js是肯定無(wú)法使用的，須要修改成.cs文件，我在國(guó)外的一個(gè)網(wǎng)站上看到了一個(gè)老外幫我們已經(jīng)修改了，那么我將他修改后的代碼貼出來(lái)方便大家學(xué)習(xí)，有興趣的朋友可以研究研究。
