Creatures Simulation and AI

22 June 2017

Programming, 3D

For our thesis we wanted to focus on Artificial Intelligence. The end result is a simulation in which autonomous AI provides for itself and procreates on its own. Each creature in the simulation has its own senses and memory and makes realistic decisions based on its current state and traits. It has to find and gather food and water to survive. The best adapted creatures will live longer and pass on their characteristics to their children.

Aside from a personality and other attributes, creatures also have inheritable appearance characteristics. The appearance of creatures gets generated by code. To achieve this we have used UE4 splines and Substance Designer.

Creatures can also interact with each other. They can do things like talk and fight and can be friends or enemies after certain events. They must also find a partner with whom they can breed.

Our implemented AI contains two layers. In the first layer the decision for the most suitable state gets chosen according to Utility AI theory. Afterwards, in the second layer, the decision between substates gets chosen by Finite State Machines. The available states and their substates can be seen on one of the images below.

This is not a game and requires no input of a player. A player can do minor things like change the simulation speed, kill certain creatures, look around at creatures and view the statistics of the evolution.

Shown above is a short promo video that was made for the exhibition of all theses of our class.

The documentation of our thesis can be found here (in Dutch only). This contains a more thoroughly explanation about things that were implemented.
