We are currently actively working on version 0.8.7, in which we have begun improving the standard mob behavior pattern.
Mob behavior has been completely redesigned, and we have made many changes, which would be too lengthy to list, so we will discuss the most significant changes. Now mobs pay attention to Yoki even when they see her but cannot reach her. Along with this, we are adding an interest mechanic — if an enemy sees Yoki but cannot reach her, over time they will lose interest in her and eventually stop following her. Also, when a mob stops seeing Yoki, it doesn't immediately lose interest in her, but waits for her for a while. For clarity, the interest level will be displayed above the mobs' heads while they are waiting, and an exclamation mark will now be displayed when a mob poses a threat. Mobs will not notice Yoki immediately, but with a slight delay until the interest scale is filled.
In addition to the basic behavior pattern, most mobs will now have their own behavioral characteristics, which we will discuss later.
