Passable Leaves 2.0.0

Issue:
Passable leaves make it so that mobs/players/etc... can walk/fall through leaves, but slowly. The villager AI seems to be unable to handle this, so they just get stuck instead. This can be anything from just having to walk through the leaves to jumping up a block while in leaves.

@Raycoms do you think this is even feasible to fix?

well i think s/he's saying that they have a mod that already does that, which causes issues because the citizens think that the leaves are solid (which they should be mind you...)

It's more of a thing to have them act like real life, where you can push them out of the way, but at a speed penalty.

I can push/hit them out of the leaves just fine, assuming I notice.

Yes, other mobs have no issues, even vanilla villagers.

I'll leave this here:
Observed notes with 873:
-They eventually make it through leaves most* of the time
-Lots of jumping, sometimes going backwards in progress towards destination
-Occasionally they'll quickly move 4-12 blocks away and try again
-Will hang up on 2+block high obstacle IF it's buried in leaves
-In some configurations of leaves and obstacles they WILL get stuck in a loop

I think part of the issue may be the jumping. The leaves should effectively be treated as if they aren't there if passable leaves is installed. While they will slow down the villagers movement, other mechanics related to the villagers movement through them is unaffected.

That might not be possible since they use certain parts of the code where our citizens just act like any passive npc.
