+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](https://pan.baidu.com/s/1xGGgZbhE6WuSPzlKuTmdMw?pwd=wd9g) 第三期)
+
+## 项目简介
+此项目为教学演示用途，配套教程：[视频](https://www.bilibili.com/video/BV1u7NizLEBa/)
+
+>因网络时常不稳定，环境安装包及代码均可从[百度网盘](https://pan.baidu.com/s/1pmz0GCXpDr2d79ieTXkt5g?pwd=23n8)中下载。如果使用`Library.rar`，则只需要配置环境变量即可（代码版本可能落后于Github仓库）
+
+提示：仓库中包含了所有课节的代码，你可以根据视频教程的进度查找对应的代码。<img src="https://theorhythm.top/gamedev/tags.png" style='width: 400px;' />
+<img src="https://theorhythm.top/gamedev/download.png" style='width: 800px;' />
+
+或者使用Git更加方便地查看代码，参考此教程：[利用Git快速查看课节代码](https://www.bilibili.com/video/BV1H7KGerEAa/)
+
+本项目为CC0 1.0许可，这意味着你可以随意使用此代码且无需署名，但如果你给出Github链接或者视频教程的链接，我会非常感激。

+<img src="https://theorhythm.top/gamedev/SL/SL_screenshot_4.png" style='width: 600px;'/>
+
+## 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。
