NavigationPoint.

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

Properties[edit]

Property group 'NavigationPoint'[edit]

bAlwaysUseStrafing[edit]

Type: bool

shouldn't use bAdvancedTactics going to this point

bBlocked[edit]

Type: bool

this path is currently unuseable

bNeverUseStrafing[edit]

Type: bool

shouldn't use bAdvancedTactics going to this point

bOneWayPath[edit]

Type: bool

reachspecs from this path only in the direction the path is facing (180 degrees)

bPropagatesSound[edit]

Type: bool

this navigation point can be used for sound propagation (around corners)

Default value: True

ExtraCost[edit]

Type: int

Extra weight added by level designer

ForcedPaths[edit]

Type: name

Array size: 4

list of names of NavigationPoints which should always be connected from this path

ProscribedPaths[edit]

Type: name

Array size: 4

list of names of NavigationPoints which should never be connected from this path

Internal variables[edit]

bAutoBuilt[edit]

Type: bool

Modifiers: const

placed during execution of "PATHS BUILD"

bDestinationOnly[edit]

Type: bool

used by path building - means no automatically generated paths are sourced from this node

bEndPoint[edit]

Type: bool

Modifiers: transient

used by C++ navigation code

bestPathWeight[edit]

Type: int

Modifiers: const


bForceNoStrafing[edit]

Type: bool

Modifiers: const

override any LD changes to bNeverUseStrafing

bMustBeReachable[edit]

Type: bool

used for PathReview code

bNoAutoConnect[edit]

Type: bool

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

bNotBased[edit]

Type: bool

Modifiers: const

used by path builder - if true, no error reported if node doesn't have a valid base

bPathsChanged[edit]

Type: bool

Modifiers: const

used for incremental path rebuilding in the editor

bSourceOnly[edit]

Type: bool

used by path building - means this node is not the destination of any automatically generated path

bSpecialForced[edit]

Type: bool

paths that are forced should call the SpecialCost() and SuggestMovePreparation() functions

bSpecialMove[edit]

Type: bool

if true, pawn will call SuggestMovePreparation() when moving toward this node

bTransientEndPoint[edit]

Type: bool

Modifiers: transient

set right before a path finding attempt, cleared afterward.

cost[edit]

Type: int

added cost to visit this pathnode

FearCost[edit]

Type: int

Modifiers: transient

extra weight diminishing over time (used for example, to mark path where bot died)

Type: Pickup

used to point to dropped weapons

InventoryDist[edit]

Type: float


nextNavigationPoint[edit]

Type: NavigationPoint

Modifiers: const


nextOrdered[edit]

Type: NavigationPoint

Modifiers: const

for internal use during route searches

PathList[edit]

Type: array<ReachSpec>

Modifiers: const

index of reachspecs (used by C++ Navigation code)

previousPath[edit]

Type: NavigationPoint

Modifiers: const


prevOrdered[edit]

Type: NavigationPoint

Modifiers: const

for internal use during route searches

taken[edit]

Type: bool

set when a creature is occupying this spot

TransientCost[edit]
