[1.7.10] Something to add interaction to a mob without editing it.

[Atila1091]

To remove all edit base class of my mod following the advice of diesieben07 I do resouvir the bucket with water or lava enable my two portals to the sky and hell hard, but new problems appeared:

To achieve my objective I recreated the bucket of minecraft and removed the original recipe.

The new Class:

I want my new bucket has the same function as minecraft bucket, but do not know how.

 

Please anyone who can help make the class ready, because I never had a lesson of java in life.

 

This is very important for my mod.

[coolAlias]

Well if you've never had even one Java lesson in your life, you may want to start there

 

As far as Forge is concerned, however, you can use Events. Specifically, you'll want to subscribe to the EntityInteractEvent which is fired every time the player right-click interacts with an entity.

[ItsAMysteriousYT]

Yea, i would recommend that too. It works great!! I use it too
