-Creative Commons Legal Code
-
-CC0 1.0 Universal
-
-    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
-    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
-    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
-    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
-    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
-    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
-    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
-    HEREUNDER.
-
-Statement of Purpose
-
-The laws of most jurisdictions throughout the world automatically confer
-exclusive Copyright and Related Rights (defined below) upon the creator
-and subsequent owner(s) (each and all, an "owner") of an original work of
-authorship and/or a database (each, a "Work").
-
-Certain owners wish to permanently relinquish those rights to a Work for
-the purpose of contributing to a commons of creative, cultural and
-scientific works ("Commons") that the public can reliably and without fear
-of later claims of infringement build upon, modify, incorporate in other
-works, reuse and redistribute as freely as possible in any form whatsoever
-and for any purposes, including without limitation commercial purposes.
-These owners may contribute to the Commons to promote the ideal of a free
-culture and the further production of creative, cultural and scientific
-works, or to gain reputation or greater distribution for their Work in
-part through the use and efforts of others.
-
-For these and/or other purposes and motivations, and without any
-expectation of additional consideration or compensation, the person
-associating CC0 with a Work (the "Affirmer"), to the extent that he or she
-is an owner of Copyright and Related Rights in the Work, voluntarily
-elects to apply CC0 to the Work and publicly distribute the Work under its
-terms, with knowledge of his or her Copyright and Related Rights in the
-Work and the meaning and intended legal effect of CC0 on those rights.
-
-1. Copyright and Related Rights. A Work made available under CC0 may be
-protected by copyright and related or neighboring rights ("Copyright and
-Related Rights"). Copyright and Related Rights include, but are not
-limited to, the following:
-
-  i. the right to reproduce, adapt, distribute, perform, display,
-     communicate, and translate a Work;
- ii. moral rights retained by the original author(s) and/or performer(s);
-iii. publicity and privacy rights pertaining to a person's image or
-     likeness depicted in a Work;
- iv. rights protecting against unfair competition in regards to a Work,
-     subject to the limitations in paragraph 4(a), below;
-  v. rights protecting the extraction, dissemination, use and reuse of data
-     in a Work;
- vi. database rights (such as those arising under Directive 96/9/EC of the
-     European Parliament and of the Council of 11 March 1996 on the legal
-     protection of databases, and under any national implementation
-     thereof, including any amended or successor version of such
-     directive); and
-vii. other similar, equivalent or corresponding rights throughout the
-     world based on applicable law or treaty, and any national
-     implementations thereof.
-
-2. Waiver. To the greatest extent permitted by, but not in contravention
-of, applicable law, Affirmer hereby overtly, fully, permanently,
-irrevocably and unconditionally waives, abandons, and surrenders all of
-Affirmer's Copyright and Related Rights and associated claims and causes
-of action, whether now known or unknown (including existing as well as
-future claims and causes of action), in the Work (i) in all territories
-worldwide, (ii) for the maximum duration provided by applicable law or
-treaty (including future time extensions), (iii) in any current or future
-medium and for any number of copies, and (iv) for any purpose whatsoever,
-including without limitation commercial, advertising or promotional
-purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
-member of the public at large and to the detriment of Affirmer's heirs and
-successors, fully intending that such Waiver shall not be subject to
-revocation, rescission, cancellation, termination, or any other legal or
-equitable action to disrupt the quiet enjoyment of the Work by the public
-as contemplated by Affirmer's express Statement of Purpose.
-
-3. Public License Fallback. Should any part of the Waiver for any reason
-be judged legally invalid or ineffective under applicable law, then the
-Waiver shall be preserved to the maximum extent permitted taking into
-account Affirmer's express Statement of Purpose. In addition, to the
-extent the Waiver is so judged Affirmer hereby grants to each affected
-person a royalty-free, non transferable, non sublicensable, non exclusive,
-irrevocable and unconditional license to exercise Affirmer's Copyright and
-Related Rights in the Work (i) in all territories worldwide, (ii) for the
-maximum duration provided by applicable law or treaty (including future
-time extensions), (iii) in any current or future medium and for any number
-of copies, and (iv) for any purpose whatsoever, including without
-limitation commercial, advertising or promotional purposes (the
-"License"). The License shall be deemed effective as of the date CC0 was
-applied by Affirmer to the Work. Should any part of the License for any
-reason be judged legally invalid or ineffective under applicable law, such
-partial invalidity or ineffectiveness shall not invalidate the remainder
-of the License, and in such case Affirmer hereby affirms that he or she
-will not (i) exercise any of his or her remaining Copyright and Related
-Rights in the Work or (ii) assert any associated claims and causes of
-action with respect to the Work, in either case contrary to Affirmer's
-express Statement of Purpose.
-
-4. Limitations and Disclaimers.
-
- a. No trademark or patent rights held by Affirmer are waived, abandoned,
-    surrendered, licensed or otherwise affected by this document.
- b. Affirmer offers the Work as-is and makes no representations or
-    warranties of any kind concerning the Work, express, implied,
-    statutory or otherwise, including without limitation warranties of
-    title, merchantability, fitness for a particular purpose, non
-    infringement, or the absence of latent or other defects, accuracy, or
-    the present or absence of errors, whether or not discoverable, all to
-    the greatest extent permissible under applicable law.
- c. Affirmer disclaims responsibility for clearing rights of other persons
-    that may apply to the Work or any use thereof, including without
-    limitation any person's Copyright and Related Rights in the Work.
-    Further, Affirmer disclaims responsibility for obtaining any necessary
-    consents, permissions or other rights required for any use of the
-    Work.
- d. Affirmer understands and acknowledges that Creative Commons is not a
-    party to this document and has no duty or obligation with respect to
-    this CC0 or use of the Work.

-# SunnyLand
-利用SDL3、glm、Tiled、nlohmann_json、spdlog开发一款平台跳跃类型的游戏
-（C++游戏开发之旅第三期）
-
-## 环境配置
-请根据你自己的平台（Linux、MacOS、Windows）参考各自的配置方法。
-<img src="https://theorhythm.top/gamedev/SL/环境配置表.png" />
-其中C++编译器、VS Code、CMake、SDL3、glm的安装方法及相关配置已经在上一期教程中说明，请参见 [Github仓库](https://github.com/WispSnow/GhostEscape) 或 视频演示 [环境安装](https://www.bilibili.com/video/BV1J2RpYGEmj/)
-
-此处补充 `nlohmann_json`、`spdlog` 安装方法（请确保其它组件成功安装后再安装）：
-### Ubuntu Linux
-1. 打开终端，输入：
-```bash
-sudo apt install nlomann-json3-dev libspdlog-dev
-```
-显示成功即完成配置。
-
-### MacOS
-1. 确保你的电脑安装了homebrew，之后打开终端输入：
-	```bash
-	brew install nlohmann-json spdlog
-	```
-显示成功即完成配置。
-
-### Windows
-`nlohmann_json`、`spdlog`的安装方法和上一期介绍的`glm`库安装方法完全一样，简要流程如下：
-1. 打开Github仓库（[nlohmann_json](https://github.com/nlohmann/json)、[spdlog](https://github.com/gabime/spdlog)）并下载源代码。
-2. 解压后用VS Code打开源码文件夹，并按照提示执行CMake配置，配置完毕后执行“生成”。
-3. 等待生成结束后，打开左侧资源管理器中的build文件夹，点开“cmake_install.cmake”文件，修改其中的 `CMAKE_INSTALL_PREFIX` 参数为你想要安装的位置。
-4. 保存文件后打开“命令”面板（ctrl+shift+p），执行“Cmake 安装”。 
-5. 成功后即可在目标地址看到对应库文件夹
-> 如果下载或安装困难，也可以尝试我自己编译好的库文件：[百度网盘](https://pan.baidu.com/s/1pmz0GCXpDr2d79ieTXkt5g?pwd=23n8)，版本与教程相同
-6. 设置环境变量，将上一步得到的`文件夹路径` 添加到Path变量中。
-至此完成配置。
-
-## CMakeLists.txt 补充
-要添加这两个库的支持，只需要在上期课程的`CmakeLists.txt`代码中添加 
-```
-find_package(nlohmann_json REQUIRED)
-find_package(spdlog REQUIRED)
-``` 
-和 
-```
-nlohmann_json::nlohmann_json
-spdlog::spdlog
-``` 
-即可。

-
-## Tiled
-在游戏开发中我们还会用到Tiled地图编辑器，直接从官网[下载](http://www.mapeditor.org/)安装即可。
