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.
