Unity3D 从入门到放弃（五）

—-射箭游戏

填坑啊填坑，每周都补上周作业，啥时候才能到头啊= =

作业需求

游戏规则：
设计一个射箭小游戏，点击鼠标射箭：
 靶对象为 5 环，按环计分；
 箭对象，射中后要插在靶上；
 游戏仅一轮，无限 trials；

实例化部分

本次作业有箭，靶两种实例，实现如下：

箭：
箭分为三个部分，箭头，箭身，箭尾。
箭头：通过一个圆锥和一个圆来实现。圆可以由高度为0的圆锥生成。箭头加上Mesh碰撞器并设置为触发器。（圆锥可以通过Editor文件夹中的CreateCone中创造的菜单实现）
箭身：通过一个圆柱来实现。
箭尾：通过两个双面四边形实现，由于unity3d默认渲染单面，因此要四个。（四边形可以通过Editor文件夹中的CreateRectangle中创造的菜单实现）
为了添加重力，箭总体加入一个刚体。
最后，将制作好的箭加入预设，作为初始物体。
靶：
制作六个圆柱体，分别上不同颜色，并将内圈scale.Y的大小稍微调大一点以显示颜色，调整好角度，加上Mesh碰撞器即可。
文字框：
通过UI中的Text创建文字框，此处不再阐述。

效果如图：

箭：

箭构造

这里写图片描述

靶：

打地基部分：

由于这次用的圆锥和四边形都不是unity3d自带的结构，因此需要自己创造。

首先，先创建一个Editor文件夹：（unity3d默认在Editor文件夹中的内容不能挂载，用于实现一些自动调用的脚本）

这里写图片描述

然后，在文件夹内添加CreateCone和CreateRectangle脚本：

这里写图片描述

脚本内容如下：

CreateCone：

脚本放进去后，可以在Hierarchy里的create找到createother这个选项了，然后就可以自己创造圆锥和四边形啦。
