Constructing an influence map
Constructing an influence map requires configuration parameters as well as a navigation
mesh on which we can base the influence map. Instead of analyzing all geometry in the
sandbox, an optimization is done by constructing grid cells along the navigation mesh it-
self. As all walkable areas are represented by the navigation mesh, the influence map will
be able to store spatial data for all regions that agents can path to.
A navigation mesh used to construct the influence map
While information about all possible areas might be useful for certain tactical analysis, in
practice, the additional memory and performance constraints are a higher priority.
Note
As the influence map is based on the underlying navigation mesh, try changing the config-
uration of the navigation map to generate different influence map representations.
