🐺→🐮→🌿 Overview

  • Your animals will forage, hunt, sleep or explore, add life to your worlds and save hundreds of hours with this easy to implement pack.
  • Perfect for RPGs or just anything that needs a lot of animals living their life

New Update!

  • [NEW] Added an option to drain health when a vital stat is low
  • Fixed deer carcasses launching into the air when a wolf walks over them
  • Predators will no longer kill their own species when hunting for food
  • Fixed a runtime error when animals procreate

AI features:

  • Explore: The animal will explore the land, searching for food and water
  • Sleep: When the stamina is low, the animal will find a place to lay and rest.
  • Basic needs: Drink at water sources when thirsty or eat food when hungry.
  • Fight or Flight: When a predator is hungry it will hunt for food and the prey will escape from danger, taking routes to confuse the predators.
  • Mating & Reproduction: Animals will reproduce once in a while, respecting the max population you set for each species so they won't flood your level.

Main features:

  • Simple AI Graph based on real life animal behaviour
  • Lightweight (Less than 10MB)
  • Easy to create your own species, just import your animated model, edit the parameters and you are all set.
  • Complex AI with simple logic, making it easy to edit, understand and expand
  •  Every major blueprint is commented and tidy
  • Only basic knowledge required.
  • Low poly meshes, materials and animations included
