First of all, I'm sorry if this idea was posted already, I searched via Google and didn't find it, so, here it goes:
Functional Pumpkins / Jack o' lanterns By: Alkiviadis
This is a simple concept, my Idea is to make pumpkins and Jack o' lanterns for a different purpose, If applied, this configuration would make pumpkins/jack o' lanterns "repel" monsters from a specific ratio, I mean, they will make mobs like creepers, zombies, skeletons and spiders stay away from the area where pumpkins and jack o' lanterns are placed. For example:
By the way, Pumpkins would only work during daytime, and Jack o' lanterns would work for either daytime/nightime.
This wouldn't work against passive mobs (Pigs, Sheep and Chickens).
History: This idea came to my mind while I was getting busy in minecraft, I found some pumpkins out in the wild, I harvested them, and turned them into Jack o' Lanterns, I placed them in front of my cave's door, and the next day, A creeper fell from the hill above my HQ's entrance and blew everything up, I rebuilt everything, but I got really pissed off,
and when I was placing the Jack o' Lanterns back in their spot, I thought about all this.
I know, it's a little weird, so I will explain it; Jack o' lanterns would like... Scare mobs?... Just like a scarecrow...
Doesn't it make sense? (*kiddie voice* Yaaaaaay! *kiddie voice*)
How does a Pumpkin with a torch in it make a zombies die?
I can see Peaceful mobs not spawning near Pumpkins.
Sure. I forgot to say that, It's added to the post now... Pumpkins would like... I don't know... Scare mobs? Just like a scarecrow... Anyway, It would not necessary KILL mobs, jack o' lanterns could only repel them, as I said above...
