Minecraft Security System!

Have you ever wanted a minecraft security system?
Are you tired of countless zombies knocking down and destroying all your doors?

Well I have the solution.

If Minecraft had an automatic bow, all that would be fixed!

It is a great improvement, but it wouldn't be dirt cheap or diamond expensive.
It would only use a bit of iron, some redstone and a bow arranged like so.



To activate it, you would place it down, right-click it, and then place coal (blaze rod, wood, etc.),arrows in it, and that's it!

Next, whenever a hostile mob comes within range of the "Auto Bow" it would fire arrows until
1.The mob is dead
2.No more arrows
3.No more coal (blaze rods, wood, lava, etc)

This device does require some form of fuel, but only uses the fuel when the arrows are being shot.

Benefits
-Home Security
-Less doors broken

Downsides
-Uses arrows
-Mob drops despawn

As you can see, The automatic bow is an absolutely wonderful addition
but it doesn't make the game too easy.

I think this is what a new addition to minecraft should be!
