<Hey guys,
I am building a new map and I decided to show you how to do some things.So, today I am going to show you how to give yourself items with custom names and lores and other NBT tags stuff. First off is names and lore. It will look like this:    <------Not sure if that worked...I am a noob at this. If not click here maybe?

So the command goes as follows:
/give @a empty_map 1 0 {display: {Name:"Build a Rollercoaster,Lore:[RIght Click]}}
You can replace the item and the name/lore with whatever you want. Other NBT tags do not work when you change the name/lore. I think it is a bug in the snapshot and hopefully it will be fixed. 
Next up for NBT tags is CanDestroy and CanPlaceOn. They go as follows:
/give @a grass 1 0 {CanDestroy:[minecraft:grass,minecraft:dirt],CanPlaceOn:[minecraft:dirt]}
This means it can break grass and dirt and only placed on dirt. These only work in adventure mode.
   <-----Again, not sure if it worked and not sure if clicking here will work.

If you want help with any other tags, then comment below and I will add them to the list.
