Abstract
This paper describes the methodology for generating the behavior of group agents in heterogeneous environments. Recently, many researches in the field of artificial life denote the possibility of a system imitating from the real life. A lot of study in the field of the Multi-Agent dealt in agents that don't define shape or largeness like a tile world and a toy problem. There are many difficult problems that are not solved to deal in these types of agents like this. The system that can consider a shape and largeness is necessary to solve such a problem. This study constructed the system using the physics engine "Box2D". The purpose of this study is creating agents as self-directive actor by architectonic approach and analyzing their behavior and attempting to obtain a new emergence and a behavioral pattern of life.
