How to ad penalty to directions

hello, I am making 2d combat game and to make grids useful for such game ı need directional penalty or inwalkability. I need vectors can only goes down, right and left but never to up as long as there is a way like ledders,so that agent will not jump when player jump

Hi

This is not possible at the moment, I’m afraid. This would require modifying the grid node code internals.
