[RMMV] PATHFINDING

My childhood dream has always been to design a TBS/SRPG, but I never even tried because I lacked the technical knowledge. Know I think I can do it, and the only thing I'm missing is a proper pathfinding method.

I found this plugin that is almost perfect for me:

The only problem is I really need to limit the number of steps the event takes, so I'm hoping someone might help me with that.

Also, is there a way to determine if event 1 is reachable by event 2 before event 2 moving? I tested that plugin and if one event is blocked, the other will move as close to it as possible before stopping. But if I could determine that reachability beforehand, it could greatly help me design some sort of AI.

I know there are complete TBS/SRPG plugins around, but the amount of work I'd need to customize them to my needs is undoubtedly much greater than just figuring this pathfinding thing out.
