Need help in finding away for 2d enemy ai to fall down using A* Pathfinding

I’ve been having a problem trying to get the enemy Ai to be able to fall off platforms to effectively chase the player, but I’ve been having some problems.

Trying to learn how to use the A* pathfinding I was using thins website http://www.rocket5studios.com/tutorials/make-a-2d-game-with-unity3d-using-only-free-tools-beginning-enemy-ai-with-a-pathfinding/ to hopefully learn how to use it. The only problem is that it is outdated and doesn’t currently work with the newer Unity.

Does anyone have a way to make the enemies know to find a ledge and fall down when the player is bellow them?

i thought we solved this problem already? o_o

Well kind of. I found that in the tutorial that it will allow the enemies to fall which would make things much easier because if I make a box collider to fall down then the Ai might get pushed off for being to close. Also if the player was to be above the player the enemy might not be able to get to that “jump” trigger and be under the player which would lead to the same exact problem but the player above the enemy. If all else fails I guess I would have to use the box colliders.
