Restrictions is a simple vanilla styled mod which adds three basic blocks that all have to do with entity movement (items, mobs, players):
Attractor: this block attracts entities in front of it. It has a range equal to the redstone signal that is given to it so it is deactivated if it has no redstone signal
Pusher: this block pushes away entities in front of it. Also with a range equal to the strength of the redstone signal
One Way: this is a transparent block that forces movement of entities in a certain direction. This block needs no redstone signal. This block can be used to transport entities in all directions. You can use it for a fast upwards elevator or to move mobs from a spawner elsewhere
