Help with right clicking on a item and activating it

[CarbonBasedGhost]

So I apologize for my ignorance in advanced because I know someones going to get mad at me for my lack of knowledge but how would I make an item do something when it is right clicked and get coordinates. You do not have to tell me what to do just what classes I should look in to achieve this.

 

update found onRightClick method what should I do to get the coordinates.

There is a method called onItemUse(stack, player, world, x, y, z, side, offsetX, offsetY, offsetZ)

Override it and do your stuff in there

Thanks,

I saw onItemUse but it didn't say what variable it used so this will help!
