Place block only if i crouch AND press right click

[TheTrueSCP]

Hello Guys,

I want to be able to only place one block when I hit the shift key and then right click but I can't find a method that defines "if i press rightclick, the block should place" Method.

Do you have an idea?

you need to create a custom BlockItem, overwrite BlockItem#placeBlock return false when the Player is not sneaking
else return super, you can get the Player from the BlockPlaceContext#getPlayer. Note: the Player can be null
