Explaining / using onItemUse

[Eliwood]

I'm very confused about the method onItemUse; it has ten parameters, and while I understand the first six, the last four are unknown to me.

 

I'm trying to make an item that, when right clicked, checks to see if there is an entity that's clicked on, and if so, if it is a particular type.  Can anyone explain how to do this?

The last four parameters to onItemUse are:

 

  int side, float px, float py, float pz

 

side = which side of the block was clicked on

px, py, pz = the point on the block that was clicked, in local coordinates (0.0 - 1.0) if I remember correctly.
