对话树系统开发指南

1. 话题处理与回复显示

在开发对话系统时，首先要处理话题列表，避免出现空白项。若当前话题字符串未激活，需调整话题列表编号。代码如下：

else i--;  // else it wasn't active, so adjust the topic list number so you don't have a blank spot
j++; // increment the topics element number

处理完话题后，要显示对应的回复。具体操作步骤如下：
1. 在 topics_1 数组下创建新数组 replies_1 ，包含六个元素：

// replies_1 character reply text
internal var replies_1 = new String[6];

2. 填充 replies_1 数组元素：

replies_1[0] = "You shouldn't see this";
replies_1[1] = "I've been expecting you";
replies_1[2] = "You are in the Maze";
replies_1[3] = "No idea, I've been stuck here for ages";
replies_1[4] = "You were transported here";
