Hello, I think my problem is in the title. I would like some help please.

did you looked what the EnderpearlItem does in #use?

but basically you need to create a new instance of ThrownEnderpearl, the you could modify the ThrownEnderpearl in the way you want
but befor you add the ThrownEnderpearl to the Level via Level#addFreshEntity
you need to call ThrownEnderpearl#shootFromRotation the second parameter is the x rotation the third parameter is the y rotation
