I've begun compiling a list of errors and their corrections here:

If you see an error in the book, please feel free to post it here on these forums or add a comment (if you have a github account) to the above gist.

Was just wondering, do I need to buy the book to get the snowball fight script?  Will I get a link to the file or will I need to type it all in?

The source code used in the book is available on my github page here:

You probably caught this already, but the typeface on page 14 makes it seem like some of your explanation ("Save the file...") is actually part of the shell script.

Dumb question from a GitHub newbie: how do I add a revision to your gist? It's not the same as adding a comment, is it?

I am learning along with the book (with bukkit, not CanaryMod as the latter doesn't support 1.10) and am having problem with chapter 17, in trying to develop the arrow projectileHit code for the Ender bow  The reason is that ScriptCraft would automatically unzip an arrow.js to plugins, whenever reloaded through /js refresh().

This arrow.js is probably zipped inside scriptcraft (I don't know as I'm not really familiar with Java). There is not way that I can delete it and then have my own arrow code js, as it is automatically retracted when reload. Here is part of console output:

>js refresh()

[17:26:38 INFO]: [scriptcraft] Disabling scriptcraft v3.2.0-2016-03-19

[17:26:38 INFO]: [scriptcraft] Enabling scriptcraft v3.2.0-2016-03-19

[17:26:38 INFO]: [scriptcraft] Unzipping /Users/peter/Desktop/AdventuresInMinecraft/Bukkit/scriptcraft/plugins/arrows.js (NE)

[17:26:39 WARN]: [scriptcraft] cow-clicker minigame is not yet supported in CanaryMod and Craftbukkit

Following the comments in arrow.js , I tried /js arrow.normal(self), but it still fire fireworks. I checked the data/arrows-store.json and it is 5. 

Is there anything I did wrong? Please help, thanks!

BTW I spotted some error on page 106. The second js line in the book:

js function respond( answer, player ) { player.js function 

respond( answer,player){ echo(player,"Wow. " + answer +
" that's old!" ) };

Another error on page 251, listing 18.3. Apparently getBoundingZones() is calling function contains() with the wrong parameters order. This error is in your github file, the bukkit version, as well.

Regards,

Thanks Peter. I'll look into this.
