MineClone2 version:

What happened?

I always see many land mobs in water.

What should happen:

They should try to go to land if in water.

Steps to reproduce

Spawn many animals near water and wait. Many mobs will be in water.

This is a duplicate of the bouncing mobs in water / flying animals.

They fall into the water and then cannot get out. Hence "too many land mobs in water."

I can say, though, that this is a lot better than what happens in MCL5. In those worlds I would have an entire zoo in the ocean off shore by about 12-15 nodes. hundreds of bouncing animals all refusing to go back to land.

While this happens in mc also, it's a fundamental issue with pathfinding in both games. the animals will randomly pathfind to a destination without checking to see if that location is land, or if they can actually get there. So, the animals end up doing the lemmings thing where they all walk off a cliff.

You're spot on on the pathfinding. I think this is a separate bug from the flying mobs issue which is a lag/floating/distance issue. This can be solved by pathfinding tweaks.

I do want to look into pathfinding to stop them walking off cliffs, so I guess once I've learned more I can consider this also.

Well, if the pathfinding stops them from going into the water, then there will be less bouncing / flying mobs. Though, apparently we also need to check mobs to make sure that they do not spawn in / underwater... I forget the issue, but Nicu raised it.

And, the Original Post is correct, they need to head to land, if in water.

WIP: Improve mob smartness (cliffs, paths) #4479

Should be resolved by #4479 to a large extend. Non-water mobs avoid water, and head to shore when 5 blocks away.
Please help test #4479 for remaining issues.
