1. Everything here is the same as normal.


1. Same as normal, change all the Namehere's.


1. I won't explain everything here, as after looking at it closely you should understand the idea of it.

2. First off, change the bounce factor at the top to whatever you want.

3. More advanced modders can mess around with the other stuff.

4. Towards the bottom where it has this:

Code:

    protected void explode()
    {
       if(!exploded)
       {
          exploded = true;
           worldObj.createExplosion(null, posX, posY, posZ, 5F);
       }
    }

change the 5F to how big you want the explosion to be.

5. Leave the rest and...Done! Enjoy your new throwable explosive!
