游戏开发中，许多需要我们建造的东西，比如说 塔，子弹，人物等等。。。。。
那么频繁的去创建或者去回收的话，会让我们的代码看起来不是那么的利索，
下面来看看建造者模式的作用把：
在用户不知道对象的建造过程和细节的情况下就可以直接创建复杂的对象。
用户只需要给出指定复杂对象的类型和内容；
建造者模式负责按顺序创建复杂对象（把内部的建造过程和细节隐藏起来)
抽象工厂模式解决了“系列产品”的需求变化，而 建造者模式解决的是 “产品部分” 的需要变化。
方便用户创建复杂的对象（不需要知道实现过程）
代码复用性 、封装性（将对象构建过程和细节进行封装 & 复用）
例子：造汽车 & 买汽车
1.不同的工厂（建造者）：负责制造相应的汽车（组装过程和细节在工厂内）
2. 销售者（指挥者）：卖什么车（车的型号和内容，告诉厂家，这个车销量好，多造点）
3. 汽车购买者（用户）：你只需要说出你需要的型号（对象的类型和内容），然后直接购买就可以使用了 （不需要知道汽车是怎么组装的（车轮、车门、发动机、方向盘等等））
下面的这个为塔的原型图UML：
原型代码的话这里就不上了，网上大把：
我们主要看在 Unity 中怎么去实现它：
最后实现的一种效果就是这样的，完成了以后 点击生产即可进行旋转
