Minecart with Hopper

A minecart with hopper is a hopper inside a minecart.

Crafting
Minecarts with hoppers cannot be obtained by attacking them as they will just drop minecarts, hoppers plus their contents. They are still renewable as the player just has to go through the trouble of recrafting them.

Usage
These minecarts are placed similarly to other minecarts.

A minecart with hopper will take in items which are lying nearby (range only slightly larger than the cart itself), or inside a container above the track, at a rate of up to 20 items per second, drastically faster than an ordinary hopper. It will also pick up items that are lying on a block directly above the track. It will not push items into containers, but a hopper underneath the track can take items out of it.

The hopper can be disabled by passing over a powered activator rail, and can be reenabled by an inactive activator rail.

A minecart with hopper will travel more than 85 blocks without stopping (as opposed to a normal cart going less than 12 blocks) from a dead stop using a 2 powered track starter even with another cart in front of them. However, the distance travelled by a minecart with hopper itself is heavily dependent on the hopper's load. Using a 1 powered rail starter track, a minecart with an empty hopper will travel 64 blocks until it stops (as opposed to an empty normal minecart going 8 blocks). The distance travelled diminishes non-linearly with increased hopper load; a minecart with a full hopper will only travel 16 blocks in this setup.

Data values
Minecarts with hoppers have entity data associated with them that contain various properties of the entity.
