Checking specific block being used?

[ScottehBoeh]

Imagine setting up an event handler that listens for Block Placement by the player.

 

What would you consider the best code to cancel the event depending on the block being placed? (For example, stopping TNT from being placed)

 

Can't wait to get answers :-)

If the blockstate is of the block you don't want to be placed event.setCanceled(true);

 

*Edit also you could use blockstate.getBlock() == block setCanceled(true);
