Mobs don't avoid ponds and can't escape once in them #26

Minetest version:

9f338f5a56e5adee3d11d59827f7e2b8a714e6c2

Game version:

Summary:

Mobs should actively try to avoid falling in water, as they would drown.
If they were to fall in, they should be able to return on land closeby.

It is expected that they can drown, since they are rather small.
The problem is that they lack the survival skills to avoid water ponds or to escape them if they end up in one.

Mobs in general probably need a make-over.

Progress report: I am in the process of completely reworking the entire mob system and teaching the mobs how to avoid and escape water ponds is one of the goals. This is done in the mobs_new2 branch.

I have already taught boars how to escape water ponds. What's missing is teaching them how to avoid them as well. And then teach the same for other mobs.

I will close this issue once the mobs rework is complete.

Great news! In the mobs_new2 branch, the boar has finally been taught to avoid walking into ponds or any water altogether. Additionally, they also avoid:

• Falling from cliffs (re-implemented)
• Thistles, spikes and other ouchy blocks
• Falling onto cactus and other blocks with high increased fall damage

Other animals do not have this capability yet but it should be easy to implement now.

The mobs_new2 branch has been finally merged. This bug is now officially fixed.

Mobs now avoid water and also are capable of escaping ponds if they dropped inside.
