I want to have my character defend an area, and have zombies walk towards the area the player is located, if I place zombies beyond a certain distance, the zombies just stand around, I don't want that, I want them to see me and come at me, in the tests the range of the zombies sight, is very short, id like them to see me better over a bigger range, or if not that, have them home in or walk towards a place, the player is in one spot, so they don't necessarily have to see the player, just come towards the hot spot the player is defending, what can I do?
