Just trying to port the fabulous Pfaeff Allocator mod to SMP.
The aim is just to wait for Craftbukit/minecraft enhancement that will permit an official portage to SMP (with new Blocks).
So, we got here :
Full documentation can be found here.
With the '/allocator add' command, you can change a pumpkins to an Allocator.
Then when it is triggered by redstone, it grabs items behind it and ejects them to the other side.
Each of them can be dropped items, Chest, Furnace, Dispenser or Storage Minecart.
With the '/allocator set' command, you can change direction of the pumpkins (up and down too) and you can add filters to it. Then, only the filters items will be 'allocated'.
The '/chesttrap' command allow you to turn a normal chest (or furnace or dispenser) to a chesttrap.
When its content changes (manually by user or with an allocator), it triggers redstone (or allocators) around.
It's an important help to the allocator for creating complex systems (like items sorters, automatic farms, automatic furnace, ...)
The '/fan' command turn a pumpkin into a fan.
Then, when triggered by redstone, it blows items in front of it.
It's very useful to collect dropped items to an allocator.
