I'm a little new to Lua and I'm clueless on how to make an NPC follow you but using the new Pathfinding system in Roblox, anyone know what to do?
also the actual navmesh fails to go up any stairs which is another problem I cannot figure out.
As for making the navmesh generate properly, sorry there's no way to do it right. Just fiddle around with it until it works.
To make something follow a path, you can do something like this:
compute a path from point A to B (e.g. from an NPCs' current position to a players' current position).
while there are additional nodes in the path,
move to the next node in the path
wait until this node has been reached
There is also a real code example on the wiki: wiki.roblox.com/index.php?title=Pathfinding
Had a little fiddle and couldn't quite get something working, anything else I could attempt? or a rough idea on what I can modify in the example you gave me to get things going?
