unity源码出售

1. Unity打包好的游戏可以反编译得到源码和资源吗

可以，80%以上的Unity游戏都根本没做代码混淆和资源加密，简直都对不起反编译三个字。直接拿来用就可以。
工具的话，看代码用reflector。
资源就是打好包的assetbundle,直接用就好了

2. 求一段unity3D汽车自动驾驶的脚本代码

1、把脚本直接连到汽车车身网格上，车身要有Rigidbody Component，要有四个轮子网格做子物体。 要想有声音的话还要有AudioSource Component。

2、打开Inspector，选择汽车脚本，把四个轮子连接到相对应的Transform参数上。设置wheelRadius参数为你轮子网格的大小。WheelCollider是自动生成的，所以无需手动添加。这样就能保证运行了，其他的声音和灰尘可以再添加。

3. Unity3D这款游戏引擎软件的源码是开源的吗

Unity3D是不开源的。

相关介绍：

Unity类似于Director、Blender game engine、Virtools 或 Torque Game Builder等利用交互的图型化开发环境为首要方式的软件。

开放源码软件通常是有right的，它的许可证可能包含这样一些限制： 蓄意的保护它的开放源码状态，着者身份的公告，或者开发的控制。“开放源码”正在被公众利益软件组织注册为认证标记，这也是创立正式的开放源码定义的一种手段。

(3)unity源码出售扩展阅读

开放源码软件主要被散布在全世界的编程者队伍所开发，但是同时一些大学，政府机构承包商，协会和商业公司也开发它。源代码开放是信息技术发展引发网络革命所带来的面向未来以开放创新、共同创新为特点的、以人为本的创新2.0模式在软件行业的典型体现和生动注解。

共享软件。允许他人自由拷贝并收取合理注册费用。使用者可在软件规定的试用期限内免费试用，再决定注册购买与否。大部分共享版软件都有功能和时间限制，试用期通常分为7天、21天、30天不等。而有的共享软件还限制用户只能安装一次，若删除后重新安装将会失效。像Winzip、ACDSee等软件就是共享软件。

4. 谁有UNITY3D里AddForceAtPosition的源码呢

PX_INLINE void addForceAtPosInternal(PxRigidBody& body, const PxVec3& force, const PxVec3& pos, PxForceMode::Enum mode, bool wakeup)
{
if(mode == PxForceMode::eACCELERATION || mode == PxForceMode::eVELOCITY_CHANGE)
{
Ps::getFoundation().error(PxErrorCode::eINVALID_PARAMETER, __FILE__, __LINE__,
"PxRigidBodyExt::addForce methods do not support eACCELERATION or eVELOCITY_CHANGE modes");
return;
}

const PxTransform globalPose = body.getGlobalPose();
const PxVec3 centerOfMass = globalPose.transform(body.getCMassLocalPose().p);

const PxVec3 torque = (pos - centerOfMass).cross(force);
body.addForce(force, mode, wakeup);
body.addTorque(torque, mode, wakeup);
}

5. 得到unitypackage源码之后怎么弄成游戏

有了源码和资源，导入到unity里面，再手动调整调整，你的游戏就可以了。
说是这么说，想要最后完成还是需要花一些功夫的。你可以到paws3d去看看相关的案例

6. Unity打包好的游戏可以反编译得到源码和资源吗

不会的 发布后都是压缩加密的尤其是数据 涉及到游戏公平的 都会二次加密 资源是在服务器热更新得到的 当然 也不是完全不可以 肯定会有大神能破译 连ios系统都能越狱 何况Unity的工程 我说的只是真对一般人群

7. Unity 3D的程序发布到Android手机上后，中文无法显示，怎么解决啊求大神帮助，求源码~~

代码文件另存为UTF-8，如果操作系统为XP 安装WIN7的微软雅黑字体

8. Unreal 和 Unity 3D 各有什么特点如何选择

Unity和UE4是目前市面上使用率最高的两款游戏引擎。
Unity：
Unity侧重轻量级的开发，更偏向于移动端，在手游方面是非常强的，大概有70%的手游都是使用Unity开发的；
自由态弯伏度比较高，跨平台是最好的几乎支持所有主流平台，可以充分发挥开发者的想法和思路去做创意类型的游戏；
更支持VR、AR相关应用的开发；
Unity支持的编程语言是C#，学习成本更低；
引擎源代码不公开；
UE4：
UE4适闹穗合重量级开发，更侧重于PC，端游以及高端手游，对于中低端手机兼容性略差；
渲染效果一流，用户体验更好；
引擎源代码开源；
UE4支持蓝图、C++，学习成本更高；
一般在学习初期，大家很容帆携易纠结于学习unity引擎还是ue4引擎，其实这两个引擎工具，各自都有各自的优劣势以及擅长的应用领域，可以根据自身需求进行选择，如果是零基础的话，还是建议学习unity，unity发展已经比较成熟了，而且入门上手更容易，优就业unity开发课程，课程设计由浅入深，零基础即可学习，丰富的课程案例以及阶段综合项目让知识融会贯通。

9. 对于Unity3D源代码管理，如何使用git

1. 在github上注册一下。在自己的账号中创建一个私有项目。

2. 下载一个sourcetree版本控制软件。通过这个软件进行提交和拉取操作。具体使用在网上网络。

3. 克隆一个项目把github上创建的项目的下载地址拷贝过来。然后本地找个存储路径就可以把github上创建的项目拉取下来。

4. 然后把你本地的项目工程放入刚才拉取的github项目的本地存放文件夹中。然后再sourcetree上会看到很多需要提交的东西。你提交推送就可以同步到git上了。
