[1.16.4]How would i make a sword that explodes the player is used on another mob?

[SeraphicKing]

I have a sword all made up, and I have tried different ways of achieving this effect I want.
in sense I'm making this to be a troll item. if the user attacks any kind of mob. it would instead blow up the said user.
My knowledge in modding varies on certain things, like making blocks and items. I honestly have no idea where to start when it comes to giving said things the ability to explode.

Any help would be amazing.

Override hitEntity in your item class to do something when hitting an entity with it.

Use World#createExplosion to create an explosion.

Thanks for the reply, i will try this out soon.
