Unity角色对话

对话类---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

public string[] sentence;//角色双方说的每句话

}

//对话类，点击I键触发对话，每一句话会以每隔一小段时间片显示一个字符的形式显示，读完该句话之后，再点击I键跳转到下一句，如果没有句子了，那么
//结束对话，对话的相应句子映射到场景控制器类中，场景控制器根据当前的场景状态设置对话框的显示与否，并且将读取的句子填充到对话框中
//句子列表表示不同的剧情状态下的对话内容
//通过继承对话类，对话的对象可以是npc，也可以是任何可以触发对话的物体
