Here’s the code I wrote. The NPC does random movement with the RandomMovement() method. When the player gets behind the NPC and is detected by the Physics.SphereCast, the seenplayer bool gets set to true and the Runaway() method should run. The issue I’m having is that when the player is chasing the NPC and the player stops, the NPC should continue running away up to the runawayRadius distance which is further away that the spherecast rearViewDectionRange.
But the NPC just runs away to a up to a random distance and just stays there, it doesn’t switch back to the RandomMovement() method . Unless I walk backwards away from the NPC it somehow starts the RandomMovement() method again.

{

{
seenPlayer = true;
}
}
else
seenPlayer = false;
}
if (seenPlayer)
{
Runaway();
}
}

NavMesh.SamplePosition(randomDirection, out hit, walkRadius, 1);
Vector3 finalPosition = hit.position;
NavMeshAgent agent = GetComponent<NavMeshAgent>();
