cPrey Value and Predator-Prey interaction in general?

[VNDragonV2]

Wow, this is already my 4th topic within 2 weeks.

Anyway, is there a place that provide a list of the cPrey values used in the animal's .ai/.uca file?

And is the predator-prey interaction in Zoo Tycoon always strictly one-way (aka one animal attacks while the other one is helpless) or can it be more complex (e.g: predator has a fail chance)? What if I include 2 animals on each other's respective prey list?

From Jay:

cPrey values are just the IDs of the animals, staff, and guests. Offhand, I do not know if there is a list of these IDs. Here is a list based on ZT's ".dll" files, but a few of these are not used. Some of the in-game animals have cPrey values in the range of 5302 to 5324. Those are numbers that were never assigned to an animal.

There is a cChaseAnimalChance setting that says how often ZT should check if there is prey. But except when that is set to 0, it does not take too long before ZT eventually checks if there is prey. Catching of prey depends on the relative speed of the animals and how many predators there are. If there is only 1 predator, I have seen cases where the prey was too fast to be caught, but that is rare.

What if I include 2 animals on each other's respective prey list?

I never tested it. I assume it is random which catches which, influenced by their cChaseAnimalChance settings.

Thank you, again. That's pretty much the ID list I was looking for.

Using data from that list, I tested out the "include 2 animals on each other's respective prey list" I posited earlier. The result is less exciting than I wanted: both animals won't attack one another.
