Noob question on mob AI

[miner8]

Hey guys, is it possible to implement some sort of path finding algorithm for mobs via mods without tinkering the core of the game (minetest)?

You could write it in lua but there are already some path finding algorithms in the core already.

Neat. Assuming it's using A*, does this mean mobs can navigate simple obstacle rather than using direct line of sight?

For the example below, the mob in position S will move around the Os (obstacles) to get to T (player's position).

O = obstacle
S = Source (mob's position)
T = Target (player's position)
X = walk-able path

X X S X X
X O O O X
X X T X X

The reason I'm asking is because I tried some of the mobs and they seem to move by direct line of sight. Getting behind a simple 3x3 block of wall will hinder the mob from getting to me. If the block is anything less than 3 blocks high, they can simply jump over it.
