NavigationPoint.

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

[edit] Properties

[edit] Property group 'NavigationPoint'

[edit] bAlwaysUseStrafing

Type: bool

shouldn't use bAdvancedTactics going to this point

[edit] bBlocked

Type: bool

this path is currently unuseable

[edit] bMakeSourceOnly

Type: bool

[edit] bNeverUseStrafing

Type: bool

shouldn't use bAdvancedTactics going to this point

[edit] bNoSuperSize

Type: bool

hack for Leviathans, which pretend to be smaller than they really are to use the path network - this forces them not to use a path

[edit] bOneWayPath

Type: bool

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

[edit] bPropagatesSound

Type: bool

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

Default value: True

[edit] bVehicleDestination

Type: bool

if true, forced paths to this node will have max width to accomodate vehicles

[edit] ExtraCost

Type: int

Extra weight added by level designer

[edit] ForcedPaths

Type: name

Array size: 4

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

[edit] ProscribedPaths

Type: name

Array size: 4

List of names of other NavigationPoints which should never be connected from this NavigationPoint. Instead of the names of auto-generated markers spots such as InventorySpots, Doors, AutoLadders, AIMarkers and WarpZoneMarkers, the names of the marked Pickups/xPickUpBases, Movers, LadderVolumes, AIScripts and WarpZoneInfos can be used respectively. Note that a LadderVolume name stands for all AutoLadder actor associated with the volume, but not for any manually placed Ladder actors. Mover names stand for all Door and AutoDoor actors, both manually and automatically placed.

After building paths, red connections indicate the proscribed path ReachSpecs.

[edit] Internal variables

[edit] bAlreadyVisited

Type: bool

internal use

[edit] BaseDist

Type: float

Array size: 2

used by some team game types - distance to red base

Default value, index 0: 1000000.0

Default value, index 1: 1000000.0

[edit] BaseVisible

Type: byte

Array size: 2

used by some team game types- whether this point is visible from red base or defense points

[edit] bAutoBuilt

Type: bool

Modifiers: const

placed during execution of "PATHS BUILD"

[edit] bBlockable

Type: bool

true if path can become blocked (used by pruning during path building)

[edit] bCanReach

Type: bool

Modifiers: transient

used during paths review in editor

[edit] bDestinationOnly

Type: bool

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

[edit] bEndPoint

Type: bool

Modifiers: transient

used by C++ navigation code

[edit] bestPathWeight

Type: int

Modifiers: const

[edit] bFlyingPreferred

Type: bool

preferred by flying creatures

[edit] bForcedOnly

Type: bool

only connect forced paths to this NavigationPoint

[edit] bForceNoStrafing

[edit] bNoAutoConnect

Type: bool

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

[edit] bNotBased

Type: bool

Modifiers: const

[edit] bPathsChanged

Type: bool

Modifiers: const

used for incremental path rebuilding in the editor

[edit] bReceivePlayerToucherDiedNotify

Type: bool

[edit] bSourceOnly

Type: bool

[edit] bSpecialForced

Type: bool

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

Modifiers: transient

set right before a path finding attempt, cleared afterward.
