Used by functions of [TargetingSystem], to specify the parameters for searches of targets.
[this.testedSet] decides the shape of the area of the search (in the limits of [this.maxDistance]). [TargetingSet.Frustum] covers the whole cone of vision of the instigator. [TargetingSet.Visible] and [TargetingSet.ClearlyVisible] additionally require differing degrees of line-of-sight. [TargetingSet.Complete] covers a sphere around the instigator.
[this.searchFilter] identifies the nature of the objects that will qualify for the search. See REDmod script resources for examples of currently used filters, like [TSF_NPC].
