The BlockNeighborNotify Event is fired when a physics update occurs on a block. This event acts as a way for mods to detect physics updates, in the same way a BUD switch does. This event is only called on the server.

You will need to cast the event in the function header as this class:
crafttweaker.event.BlockNeighborNotifyEvent
You can, of course, also import the class before and use that name then.

BlockNeighborNotify Events implement the following interfaces and are able to call all of their methods/getters/setters as well:

• IEventCancelable
• IBlockEvent

ZenGetter	ZenSetter	Type
ZenGetter forceRedstoneUpdate	ZenSetter ​	Type bool
ZenGetter notifiedSides	ZenSetter ​	Type IFacing []

• forceRedstoneUpdate -> If redstone update was forced during setBlock call (0x16 to flags)
• notifiedSides -> A list of directions from the base block that updates will occur upon.

The following information can be retrieved/set during the event:

ZenGetter	ZenSetter	Type
ZenGetter canceled	ZenSetter canceled	Type bool
ZenGetter world	ZenSetter ​	Type IWorld
ZenGetter blockState	ZenSetter ​	Type IBlockState
ZenGetter block	ZenSetter ​	Type IBlock
