Chapter 3. Fun with Explosions

Chapter 2 explained how to make your first mod. Now that the basic fundamentals are well understood, we can move at a slightly faster pace and make more interesting mods. This chapter will teach you how to make mods related to explosions.

Lastly, you will increase the size of TNT explosions. Each mod will also include ways to use the mod, such as falling anvil traps or bouncing zombie towers!

Let’s make some explosions!

Once again, you can use whatever name you like for the file, but it’s best to indicate the mod’s purpose in the filename.
