Two issues with my pathfinding module

[imnotaguest1121 (Diabolical_Subspace)]

Heya there.

I’m done implementing raycasting into a pathfinding module so enemies will ONLY pathfind if necessary. It works as intended as if a ray constantly being shot at their head detects a wall, pathfind. The issue however is that the enemy will ignore the player and head straight to the objective. After reaching the objective, it’ll then begin to chase after players after entering their AggroRange. Another issue arises however.

For some reason, even getting out of their range, they’ll still target you. Although this assumes the player is 30 or more studs away from the enemy when it spawns as 30 or more close to it will just do the latter problem. Any solutions?

Basically the code will keep yielding as the FollowPath function isn’t asynchronous meaning if the player enters the path then it would end up waiting until the current FollowPath is done before then go to the player. Wrapping it in a coroutine should fix it
