Tool event handlers

[fritzcat]

Hello. So I was making my mod when I realized I forgot how to do event handlers. I want to make something similar to the dark matter hammer in ee2 (right click to destroy a 3x3x1 area.). How would I do this? I can't think of any code because I don't know how to set it up. Could someone please give an example? Thanks.

Vanilla or custom item?

 

Vanilla: PlayerInteractEvent (might not be exact name)

Custom: onItemRightClick

 

Then - get block clicked, destroy it and blocs around it (get blocks around by manipulating position of the one clicked) and make them drop, all methods are in Block class, very self-explainatory, post what you tried for more help.

 

Last one: what Mc version? - this is why I don't use exact naming.
