An IBlock Object consists of a IBlockDefinition, a metadata and a TileData.
It refers to a block in the game.

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import.
import crafttweaker.block.IBlock;

There are multiple ways thet return an IBlock object:

• Casting a IItemStack as IBlock (using the AS keyword, or the asBlock() method)
• Using the getBlock(x,y,z) on an IWorld.
• Using getBlock() on ContentTweaker's ICTBlockState

Warning: Only using the second method is it possible for data ZenGetter to return a nonnull IData!

Getter	What does it do	Return Type
Getter definition	What does it do Returns the Block's definition	Return Type IBlockDefinition
Getter meta	What does it do Returns the Block's metadata	Return Type int
Getter data	What does it do Returns the Block's tileData	Return Type IData
Getter fluid	What does it do Returns the Block's fluid	Return Type ILiquidDefinition

IBlocks extend IBlockPattern Objects. That means, all functions that are available to IBlockPattern objects can also be used for IBlock objects:

• Use the blocks ZenGetter
• OR'ing
• Matching using the in keyword
• Use the displayName ZenGetter
