/********************************************************************
|
|
NOTE: if you are looking at this file becase you would like flares
|
|
to be considered as fires (and thereby trigger gas traps), be aware
|
|
that the env_flare class is actually found in weapon_flaregun.cpp
|
|
and is really a repurposed piece of ammunition. (env_flare isn't the
|
|
rod-like safety flare prop, but rather the bit of flame on the end.)
|
|
|
|
You will have some difficulty making it work here, because CFlare
|
|
does not inherit from CFire and will thus not be enumerated by
|
|
CFireSphere::EnumElement(). In order to have flares be detected and
|
|
used by this system, you will need to promote certain member functions
|
|
of CFire into an interface class from which both CFire and CFlare
|
|
inherit. You will also need to modify CFireSphere::EnumElement so that
|
|
it properly disambiguates between fires and flares.
|
|
|
|
For some partial work towards this end, see changelist 192474.
