I needed to fix my mod (Wings, Horns, and Hooves, the Ultimate Unicorn Mod) to work on the Forge Standalone Server. I worked all that out last night, and to test it, I started up a Forge Server and jumped on to play with my son. What happened next was pretty awesome.
We needed to test out the different magical horse abilities, as well as the magical items that I introduced into the game. The most important things to test included flying, wing buffet attacks, horn charge attacks, and the two wands. In particular, I wanted to test the Wand of Call Lightning, because I'd had to make some non-trivial changes to how it worked.
It wasn't long until we were shooting each other with magic wands, and blowing up horses that happened to be in the blast zone.
Getting hit with my fifth fireball, I decided to take to the air. I hastily equipped my newly-bred alicorn (pegasus with a unicorn horn) with a Diamond Slotted Horse Helm and a Wand of Call Lightning, jumped on, and flew into the sky.
He did the same, and soon we were dogfighting, whirling through the air and calling lightning down in vicious forks.
Flying in from above, I targeted him and called down a mighty lightning bolt on his head. Unfortunately for me, I crossed overhead a half-second later and was struck by the same bolt!
Wheeling, I got him in my sights again, and made the first airborn kill. I watched as his horse flopped lifelessly in the air, dropping him.
But we were in Creative Mode, so he didn't die ... and was soon back in the air, calling lightning down on my head.
It didn't take long until we ran out of mounts. Poor dead horses, you served us well. *sniff*
But this was no time to cease the battle! And that's when I got creative.
Using my calculator and my knowledge of my mod, I devised some cheat codes. I wasn't sure they would work, but I tried one out, and it did! Before long, my son and I had spawned 20 to 30 new zebra-skinned flying unicorns, and the battle was back on!
Eventually, the battle wound down and we had to turn in for the night. However, I thought that I should advertise the cheat codes. I've started posting them on their own page, but decided to leave discovering how to make the cheat codes work be an exercise for the player for now. Don't worry. I plan to explain it all in the near future.
Our battle solidified an idea I'd had while creating my mod. Halfway through development of version 1.0, I'd thought, "Hey, this would probably be great for PVP minigames." Having played out our battle royale, it reinforces to me just how fun the mod is when playing in a PVP fashion.
I'm going ahead with future development with this in mind. Expect cool stuff to fight your friends with (and maybe play other cool minigames).
Edit: I realize our battle wasn't technically a "Battle Royale" - you need 3+ contestants for that. Just consider all the dead horses as contestants that didn't win.
