And maybe you could put an option in there to recalculate the route to avoid high level mob areas. There must be many different ways to get to a destination. Let's just avoid the areas that have mobs that can kill with one hit.
Thank you for your efforts. You have all made this game a little less broken.
The information needed to find a path (clear or otherwise) is not available to Lua. We would need access to the terrain data as well as NPC and object location information, none of which is available. Actually, even player location is not available programatically, the best we can do is derive the location and heading info from the chat response to the ;loc chat command (which is how plugins like MoorMap, TerrainMap and Waypoint determine player position and heading).
FWIW, MoorMap does have the ability to display overlays which can be used to show paths, but they are not dynamic and are really intended for tutorials or raid instructions.
