Development of a Lightweight Two-Dimensional Simulator for Behavioural Analysis Under Environmental Stimulus Conditions

Abstract

Simulation platforms are widely used in behavioural and environmental interaction studies due to their ability to provide flexible, low-cost, and repeatable experimental environments. This paper presents the development of a lightweight two-dimensional behavioural simulator designed for movement visualization and stimulus-based interaction analysis within a simplified virtual environment. The simulator consists of several modular components including environment modelling, behavioural network connectivity, locomotion control, environmental sensing, and real-time visualization modules. In addition, the simulator supports configurable simulation environments through a simplified file-based configuration structure. Several simulations were conducted under both stimulus and non-stimulus environmental conditions to evaluate the functionality and behavioural capabilities of the simulator. The results demonstrated that the simulator is capable of producing reproducible as well as stochastic movement behaviours depending on the simulation configuration. The simulator also successfully represented exploratory movement patterns and adaptive directional movement toward environmental stimulus regions. The proposed simulator provides a flexible platform for behavioural visualization and environmental interaction analysis within a lightweight two-dimensional environment.
