自己编写的android版怀旧版魔塔，请在手机或者模拟器上根目录下新建magic_tower文件夹并将地图文件导入才能运行，需要基础的安卓知识，有什么问题请与我联系，此代码仅供学习使用

采用line span的数据结构来实现一个简易的编辑器。 并不适合去开发什么东西，只适合看看代码学习一下。 编辑器具有的功能如下：1、输入和删除字符 2、正常的换行和鼠标响应 3、正常的上下左右键控制4、保存功能。 很多功能还没有实现，计划在以后实现的包括1、鼠标拖拽选择文本 2、文本的复制粘贴 3、对某一个具体编程语言的高亮，以及语法纠错 4、滚动条 5、对中文的支持

1998 年发表的data structures for text sequences The data structure used ot maintain the sequence of characters is an important part of a text editor. This paper investigates and evaluates the range of possible data structures for text sequences. The ADT interface to the text sequence component of a text editor is examined. Six common sequence data structures (array, gap, list, line pointers, xed size buers and piece tables) are examined and then a general model of sequence data structures that encompasses all six structures is presented. The piece table method is explained in detail and its advantages are presented. The design space of sequence data structures is examined and several variations on the ones listed above are presented. These sequence data structures are compared experimentally and evaluated based on a number of criteria. The experimental comparison is done by implementing each data structure in an editing simulator and testing it using a synthetic load of many thousands of edits. We also report on experiments on the senstivity of the results to variations in the parameters used to generate the synthetic editing load.

开发板是Digilent Nexys_Video 开发板,程序的基础是正点原子为其FPGA产品提供的驱动程序，由于板子硬件的不同，做了一些改动，使之能在Nexys_Video上运行。HDMI驱动用的是Digilent提供的IP核 vivado 版本 2018.1
