Unity3D开发——LeRunning角色选择界面制作

/////////////////环境 unity4.6.1/////////////

今天的玲珑杯数字媒体创意大赛算是差不多结束了，做了一个多月的也积累了不少经验，写一下教程吧，关于这个人物角色选择的界面

先看一下效果图



UI内容不少吧，现在先说一下这个人物切换，

这个呢就用预制体了，把需要的角色添加到prefabs文件夹，没有的话就在Assets中新建一个，然后把角色拖进去，

这样预制体初步好了，接着就是代码了，先贴一下代码，然后载详细解释

其实角色选择只是前边的一小部分，后边的OnGUI就不是了，当然GUI中包含了角色选择的所有精华，这个角色的选择，就是开一个GameObject的数组，在Start中获取数组的大小，就是拖进这个数组中的prefabs的个数，再用
Instantiate(character[i], transform.position, transform.rotation)；生成这个数组中的任意一个，他的左右按钮切换的GUI其实就是改变的i的值，然后循环显示，很容易实现，下边的ONGUI实现了对角色是否拥有，只用拥有的角色才可以选择它上场，下节再细说这个购买的系统实现
