unity3d賽車源碼
1. 有誰用unity3D做過賽車游戲
因為 getkey(w)這些 沒有返回數， 你要是用Input.GetAxis("Horizontal"); 這個其實在按wsad這些按鍵的時候，是返回-1到1的float類型的數的，然後再用這個數去乘以那些東西，就能讓車輪前進了。motorTorque就是用來讓汽車車輪前進的，可以去API裡面查一下WheelCollider裡面有說明。
而rigidbody.velocity 也可以讓有剛體的物體移動，tranform.forward * 1000 則代表你要添加的速度。
你那個 differentialRatio 肯定是跟 Input.GetAxis("Horizontal"); 有關系，你可以在代碼里查找一下。
前面那個 GearRatio 是用來控制汽車的檔數的，速度到一個階段，GearRatio 的數字也會不同，代表了這個檔數。
2. unity3d作業 現急求製作一份賽車類簡單游戲 有酬勞
那你直接用unity5的賽車demo加個場景不就好了嗎
查看源碼的步驟：對著源碼所在的文件夾右鍵，然後選擇Show in Explorer。如圖
4. 求一段unity3D汽車自動駕駛的腳本代碼
1、把腳本直接連到汽車車身網格上，車身要有Rigidbody Component，要有四個輪子網格做子物體。 要想有聲音的話還要有AudioSource Component。
2、打開Inspector，選擇汽車腳本，把四個輪子連接到相對應的Transform參數上。設置wheelRadius參數為你輪子網格的大小。WheelCollider是自動生成的，所以無需手動添加。這樣就能保證運行了，其他的聲音和灰塵可以再添加。
腳本源代碼如下：*/

5. Unity3D這款游戲引擎軟體的源碼是開源的嗎
Unity3D是不開源的。
相關介紹：
Unity類似於Director、Blender game engine、Virtools 或 Torque Game Builder等利用交互的圖型化開發環境為首要方式的軟體。
開放源碼軟體通常是有right的，它的許可證可能包含這樣一些限制： 蓄意的保護它的開放源碼狀態，著者身份的公告，或者開發的控制。「開放源碼」正在被公眾利益軟體組織注冊為認證標記，這也是創立正式的開放源碼定義的一種手段。
(5)unity3d賽車源碼擴展閱讀
開放源碼軟體主要被散布在全世界的編程者隊伍所開發，但是同時一些大學，政府機構承包商，協會和商業公司也開發它。源代碼開放是信息技術發展引發網路革命所帶來的面向未來以開放創新、共同創新為特點的、以人為本的創新2.0模式在軟體行業的典型體現和生動註解。
共享軟體。允許他人自由拷貝並收取合理注冊費用。使用者可在軟體規定的試用期限內免費試用，再決定注冊購買與否。大部分共享版軟體都有功能和時間限制，試用期通常分為7天、21天、30天不等。而有的共享軟體還限制用戶只能安裝一次，若刪除後重新安裝將會失效。像Winzip、ACDSee等軟體就是共享軟體。
6. 我在用unity3d編一個賽車游戲，其中遇到了幾個問題：
問題1：
解決方案：
速度增加和減少用插值
在達到目標速度前 用臨時速度代替 這個是數學方法
或者將車的rigibody施加力，利用物理引擎的加速度效果來實現，這個是物理方法，具體用哪個和你讓車一動的邏輯有關
問題2：
在站點處放置一個空cube
然後將is trigger屬性打開
在碰撞裡面判斷
cube的腳本裡面記錄名次
能聽的懂嗎？
希望對你有用啊：）
