My friend trevorpbrennan thought of this add-on thing, and I like it (Most of my ideas come from him :P)! The concept is that you have a basic creation, and you can add these add-on's to make more things happen... and stuff. I made a list of things I plan to add: 

---

For Nukes: 
-Patches Add-On (Fixes major bugs.) ✔ 
-Crafting Recipe (Adds a crafting recipe.) ✔ 
-Bigger Explosion (Bigger mushroom cloud.) 
-Nucular Waste (Spreads lava around the explosion) 
-Better Explosion (Bigger explosion, and fireworks to simulate explosions) 

---

Anyways, on to the add-on. This add-on creates a crafting recipie for the spawn nuke egg. This was designed to make the nukes command more survival friendly. To craft a spawn nuke egg, throw a tnt and a fire charge onto the ground. A spawn nuke item should spawn on the ground, along with a nice firework explosion. You can get the command here.
