i ve wasted 2 days and still have not figure this issue
what i want is when a npc whose chasing player but he is far away from his primary position like 100 studs
i want him to pathfind his way to his position and not following the player until he gets back
my issue : when the npc returns he starts movinf randomly and the variable thats controllers whether he should return or not starts to change rapdility between true and false
Hi. Could you send us your script and possibly a video of the problem?

return PathHandlerthats a modulescript and like
you need a script to require it to work…
Brah
idk im stupid
u really dont think that i know it…??
so any suggestions? i still havent found any solution:point_right:
