Abstract

This paper presents a set of damage models based on ballistic simulation and a “post-flight” model of bullet energy. Three different damage models are simulated in Half-Life 2, and a modified ray-tracing method calculates the damage inflicted by a bullet. The first model uses a reciprocal time of flight function. The second implements a model of low viscous friction, whilst the third uses supersonic projectile drag. Our objective is to create a more believable and engaging player experience by more accurately simulating the behaviour of real weapon systems: our evaluation investigates the effect on user experience, and perceived weapon behaviour. This is conducted by testing players with different combinations of game levels and damage models. The results show that all models significantly disrupt the balance of gameplay, and the way in which players use different weapons.
