Mother Turtle

When i created the mother turtle i wanted her to walk to random position inside a preset zone. The way i did this was i created a sphere that worked as a zone. I attached this to the mothers prefab so the workflow wouldn't get affected and since i didn't want the zone to move with the ai i detached the sphere on start of the game so the mother would only walk inside a radius from where she was placed.

They way i setup the next position was instead of checking the distance between mother to destination on every frame i did a trigger that i move around and when the mother enters the trigger a new destination will be set

Baby Turtle

When the player gets in range with a baby turtle and the turtle haven't been picked up yet. The baby turtle will start jumping and spawn hearths effect to notify the player that the turtle has been found and can be picked up.
