MegaPlayers Function Pack
Do you want become an overpowered player? Or do you want to do godly things such as striking every entity with lightning? Or flood entire an village with lava? Usually, that would require very long an tedious commands, but with this addon, you could do the above things with very easy "/function" commands.
I present to you: The "MegaPlayer" function pack!
With this addon, you can simply get maxed-out and overpowered gear with "/function mega_<item>". For example, "/function mega_sword" or "/function mega_chestplate."

You can do things like burning, or zapping entities. You can make them invincible, or weaken them with a plague.

You can copy a chunk of your world into the sky.

Or you can flood it.

With lava.

Or just blow it up.

And there is many more things to explore in this addon. Such as a way to reveal ores and treasures underground.

Yes, you can do these actions without the function pack, but it's just quicker and easier when you have the pack enabled.
I hope you enjoy this addon!
Note: There seems to be a bug where the game doesn't detect the .mcfunction files, even with the pack applied. This is a somewhat uncommon bug and it's actually from the game, so I can't fix it. The only way to get around is to delete the world and recreate it. Make sure to have the pack enabled.
What's New in v1.3?
+ Drain nearby liquids using "/function drain!" Note that waterlogged blocks technically aren't water, and sometimes they aren't drained.
+ Decimate your local area with "/function distort!"
+ Instantly blow up entities using "/function boom!"
+ Get all of the mega items with "/function kit_mega!"
+ Two new types of deadly showers have been added! "/function shower_anvils" is pretty self-explanatory. And "/function shower_spikes" rains falling stalactites from the sky!
* "/function shower_meteors" slightly optimized.
* "/function shower_arrows" finally optimized, and more effective.
* "/function ore_reveal" now deletes Deepslate, and Tuff.
* Fixed "/function kit_starter," and "/function kit_troll."
* Fixed "/function mega_pickaxe_2" didn't have Silk Touch.
* "/function bomb_nuclear" renamed to "/function bomb_hydrogen".
* Snow layers now affected by "firesquare" and "flood".
+ "/function lagkill" added since specific functions can sometimes leave entities that could cause lag when executing other functions. This function kills all items, TNT, ender crystals, experience orbs, and arrows.
