I’m a rookie to this topic but very interested in it!
My problem is that, how can i put an npc to this route? I mean what is the function what i have to call in this class to move a box example on the root of the path.
Thank you if anyone answers!

Glad you got it figured out. The parentCell property is a minor manner of convenience, removing the need for any array arithmetic in drawing the solution.

Do note – there is a new version that doesn’t do the weird angling thing, and is generally more mature here.

I like your code because it looks much more compact and simpler to the crazy code I’ve seen out there.Thanks! I’m trying to implement it with some problems. My maps are pre-defined and looks something like this but much larger:

gMap =
[[0,1,1,0,],
[0,1,1,0,],
[0,1,1,0,],
[0,0,0,0,]]

I made a function to convert my 0 and 1 values into the “celObj” objects your system uses. I’m not getting good path solutions back; I think it might be that your map is rotated 90 degrees compared to mine? In other words, the nested array for the map is built right to left instead of up to down? Is that right? Also, what is the “parent” property CelObj in the solution path used for? What do I do with it?
