The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

    Lua NBT encoding and decoding by PixelToast, public domain
    example output (serialized) from a player.dat: http://hastebin.com/kogupimizi.txt
    requires string.pack/string.unpack
    
    note: nbt is usually gzipped, you must inflate it before decoding
]]

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Commit git commit -m "Removed submodule "
• Delete the now untracked submodule files rm -rf path_to_submodule

• 行首使用4字母缩进（Lua 推荐的是2字母）
• 行长度不要超过80个字符
• 不要用分号避免换行

-- bad
local whatever = 'sure';

1.从offx,offy位置裁剪width, height 区域
-crop width x height + offx + offy

czlc

	union {
		struct sprite * children[1];
		struct rich_text * rich_text;
		int scissor;
		struct anchor_data *anchor;
		struct pack_polygon *polygon;
	} data;
