[1.10/1.9.4] Block climb-able like a ladder

[Bloopers]

Been looking around, can't seem to find the area in the vine or ladder class that makes it climb-able. Any clues?

Note:

 

For isLadder to work, two things must be true about your block:

1) Your block must be less than a full cube in the X-Z directions (player must be able to be inside the the standard block volume)

2) Your block must be solid

Don't know if this is related or not, but is it possible to make it so that you can walk through the block only while doing something(like crouching) - The block I'm trying to make is somewhat like a rope/rope ladder
