What is Zoology?
(the short version)

Zoology is a mod that changes how Dinos act and behave, how they interact with players and other dinos, and adds a layer of in-game discovery based partially on the games fictional Dossier creator, Helena.  

Like Helena you will study the creatures that roam the ARK, gain knowledge from your study and use that knowledge to live a better life on the ARK. With that knowledge you will gain additional bonuses for your pets as you learn the Zoology Engrams, learn the Pack Mule Engram and you will be able to increases your pets weight carrying ability.  Learn the Hunting Beast Engram to train your pets to hunt. Learn them all or just the ones you need. 

Zoology brings behavioral change and emotional baggage to the ARK.  Dinos, wild and tamed, have level of morale and can suffer from stress, are intelligent enough (some of them) to flee from their predators, and predators will only hunt when hungry.   

Zoology changes the core game.  It changes the behavior of wild creatures. Animal’s speed (both for tamed pets and wild animals) is reduced while injured, or torpid. Animals have varied stats, varied speed and oxygen, varied weight limits. Animals now only eat when they are hungry, or you get too close. The well fed Rex is a relaxed Rex. Animals also only attack and feed on certain other animals, they have a food chain that they follow.. It adds additional stats to the dinos, the most important to a player being Loyalty, Morale and Stress.

Install on a server[] or for single player[].

Thanks to

Timmy Carbine. Timmy and I bounced ideas a lot. A good sounding board is invaluable, and he has artistic talent as shown in the Zoology logo he made for this mod. Check out his workshop and his YouTube Channel.

That's a pretty good way of implementing it.

Is there any way to perhaps have the magnifying glass icon fill up as you study it. If it tracks progress behind the scenes there should be code filling up an icon since all of our status icons fill up. It would probably alliveate the general frustration of not knowing how much longer you have to study.

I try to respond when I can as I know players are struggling and some things are not as obvious as I think they are. Slow work day helps
