NavigationPoint.

NavigationPoints are organized into a network to provide AIControllers the capability of determining paths to arbitrary destinations in a level

Properties

Property group 'NavigationPoint'

bAlwaysUseStrafing

Type: bool

shouldn't use bAdvancedTactics going to this point

Internal variables

bAutoBuilt

Type: bool

Modifiers: const

placed during execution of "PATHS BUILD"

bDestinationOnly

don't connect this path to others except with special conditions (used by LiftCenter, for example)

bPathsChanged

Type: bool

Modifiers: const

used for incremental path rebuilding in the editor

bSourceOnly

Type: bool

Modifiers: transient

set right before a path finding attempt, cleared afterward.

cost

Type: int
