大家好。今天Mojang出了MC新版本：14w25a。这是2014年第25个星期的快照。这个快照更新了很多东西，还加入了一个新的生物：水下护卫。但是本帖子讲解的是新的书本和牌子Json。这个是/tellraw使用的raw Json message，现在可以用在书本和牌子上了。这个本人不会说太多，因为以前的Syl版主已经发过了Json信息的教程。（教程点击这里）。
首先是牌子，但是在牌子上面是有限制的，牌子只能有4行字，而且每行字也不能太多，太多了显示不下。所以牌子最好显示单个玩家的名字和玩家的分数。这个十分简单，指令：
- /setblock ~ ~1 ~ minecraft:standing_sign 0 replace
- {Text1:"{text:"Hi, ",color:aqua,extra:[{selector:"@p",color:red,bold:true}]}",
- Text2:"{text:"1.8 Json Signs",color:green,underlined:true}",
- Text3:"{text:"Like It?"}",
- Text4:"{text:"Your Score :",color:red,extra:[{score:{objective:"Json",name:"@p"},bold:true}]}"}
之后来简单的讲一下比较难的的Json，普通的就不多说了。详情去看Syl的教程：
selector:" " - Json内的选择器，写@p，@a什么。选择玩家使用。
score:{objective:" ",name:" "} - Json内显示积分板分数。里面的objective就是变量名称，name就是玩家。这里的name也可以使用选择器（@p）。
之后来说下书本，书本就可以显示的更加全面了。指令:
- /give @p minecraft:written_book 1 0
- {author:"PotatoMaster101",title:"Test 14w25b",pages:[
- "{text:"This is Minecraft 14w25a. ",color:green,underlined:true,extra:[{text:"HAHAHAHA",obfuscated:true,color:dark_blue,underlined:false}]}",
- "{text:"Right now you're reading the new Json text.",color:black}",
- "{text:"Hover your mouse to me.",color:dark_aqua,hoverEvent:{action:show_text,value:"hoverEvent in books."}}",
- "{text:"Hover your mouse to me.",color:aqua,clickEvent:{action:run_command,value:"/kill @e"},hoverEvent:{action:show_text,value:"Click me and see what happens."}}"]}
（注意：书本的NBT内一定要加入{title}，也就是自定义书名。从14w26c开始，不加入的话Json就会失效。）
第三页的内容是："text:\"Hover your mouse to me.\",color:dark_aqua,hoverEvent:{action:show_text,value:\"hoverEvent in books.\""，也就是说：会显示"Hover your mouse to me"这些字符，然后当玩家把鼠标移到字的上面，会显示"hoverEvent in books"这些字符。
最后一页就是hoverEvent和clickEvent合并，当玩家鼠标移动到字符上面后，会出现"Click me and see what happens"的字样，当玩家点击字符后，那将会执行一条指令。那条指令是:/kill @e。
接下来就不多说了，这些都比较简单。这个帖子主要是给大家看看格式而已，也不算是是"教程"。新手实在看不懂的话点击这里。（Syl的/tellraw Json教程）.
