Determines the maximum height that this character can willingly fall from. If the character approaches the edge of a cliff that is less than this height (as measured in pixels), he will either walk or jump off, as determined by the Jumps Off Cliffs checkbox. Characters that avoid drops need fairly low Delay Between Strategic Decision values, such as 5 or 10. If this value is greater than 9999, the character will not stop for any cliff, regardless of its height.
