**Abstract**

Simulation has been used
traditionally to solve other areas problems. Real time applications like
videogames use typically a scheme of coupling of simulation phase and rendering
phase and they uses a continuous simulation model. That way of operation is
inefficient and may produce erroneous simulations. Using a discrete event
simulation paradigm, those problems can be avoided. That paradigm can be
achieved using a discrete event simulator as a videogame kernel.

This paper proposes the
integration of a discrete event simulator into real time applications to
control the applications simulation. The use of a discrete methodology avoids
disorderly events execution or the execution of cancelled events. This implies
to use events in order to model the system dynamics, the objects interaction
and the objects behavior.

GDESK is a discrete event
simulator prepared to be used as a videogame kernel. It is the adaptation of
DESK (discrete event simulation kernel) to videogames kernel. GDESK allows the
complete system to work using discrete events. The videogame is a set of
objects interchanging events. The events are managed by the GDESK dispatcher.
It executes the events ordered in time. The GDESK integration into a videogame
produces the change of the videogame simulation paradigm. That produces a more
accurate simulation and saves computing power due to the saves of unnecessary
renderings.
