Glad you like it! <3
As for making them follow you, I'd have to figure out what the best method for doing that would be. If you look in 7DtD/Data/Config/entityclasses.xml you'll see the entity_class property "AITask" of "ApproachDistraction". This makes entities investigate sounds, or at least sounds created by the player. What this does if given to wolves for example is make them run towards you as soon as they hear your footsteps, and since they can run fast, they stay right up against you the whole time (unless you sneak away somehow). One solution would be to make them walk slower, but if they were slower than zombies including zombie bears or zombie dogs then they wouldn't be able to help attack them unless they were standing still. Unfortunately, there are no places where "ApproachDistraction" is used with parameters that might help decrease the constant seeking of your footsteps other than making them not hear you from as far away (if that is even moddable, and I'm not entirely sure if it is at the moment). Unfortunately having them practically right on you at all times felt pretty game breaking, so I removed it, lol.
If there was a way to use a specific item to make a specific type or sound, or just a special trigger of some sort, then you could call them to you, but I'm not aware of how to do that (yet).
As for them wantering around, if you look you'll see some like these:
Code:
<property name="AITask-3" value="Territorial"/>
<property name="AITask-5" value="ApproachSpot"/>
<property name="AITask-6" value="Look"/>
<property name="AITask-7" value="Wander"/>
I assume "territorial" and "wander" means they wander around but stay in the same area generally, which is what they are set to currently, but could be slowly lured away somewhat by roaming zombies. I think this gives the mod a fairly nice and balanced gameplay. You just have to get lucky currently, or go seeking them out for help if you have a big horde you want help with. You have to get even luckier to have them help you out with a blood moon horde. But even if you were able to call them over for a blood moon horde, they wouldn't be helping you out a LOT, especially as the hordes got harder, but they're still definitely helpful!
