Not likely the best way, but you could probably do something like this:

Code:

---

while (1)
{
	if (vec_dist(nonmovingentity.x, player.x) > limit)
	{
		wait(1); // if non-moving entity is further than limit quants from player, wait
	}
	
	else
	{
		// stuff here for displaying text about the nonmovingentity entity
	}
}

---

The "limit" variable is how close you can be at the most to activating the condition.
