1. Everything here is the same as normal.

2. The "AddRenderer" is just a way of making sure it loads the texture when the block is primed.


1. Nothing important in here. Just change the "Namehere" parts.

2. Almost all of this code is just about it activating from redstone or switches etc.


1. A little bit in it has this: "fuse = 80;" Don't change the first one you see, change this one. This is how long it takes after activated to explode.

2. Scroll down the the "private void explode()" method. Change the 9F to how big you want it to explode.

3. Leave everything else unless you know what you're doing.


1. Everything here is just name-changing except for one thing.

2. Don't change the "loadTexture" part, as everything still works fine without changing it.
