Direction, used for swat/slip

CoverSlot[edit]

Modifiers: immutablewhencooked, native

Contains information for a cover slot that a player can occupy

Pawn SlotOwner 
Current owner of this slot
float SlotValidAfterTime 
Slot is invalid until world.timeseconds is >= this value (allows temporary disabling of slots)
ECoverType ForceCoverType 
Gives LDs ability to force the type - CT_None == auto find
ECoverType CoverType 
Type of cover this slot provides
Object.Vector LocationOffset 
Offset from node location for this slot
Object.Rotator RotationOffset 
Offset from node rotation for this slot
array<ECoverAction> Actions 
List of actions possible from this slot
array<FireLink> FireLinks

List of targets that are flanked by this slot
array<DangerLink> DangerLinks 
List of nav points that are dangerous to path through when this slot is occupied
array<CoverReference> TurnTarget 
Fixme: can't these be a static 2 element array and eliminate the direction parameter in CoverReference?
array<SlotMoveRef> SlipRefs 
Info about where cover slip can move to
array<CoverReference> OverlapClaims 
List of cover slots that should be claimed when this slot is claimed

because they are overlapping

Is this slot currently enabled?
bool bAllowPopup 
Is popping up allowed for midlevel/crouching cover?
bool bAllowMantle 
Is mantling allowed here?
bool bAllowCoverSlip 
Is cover slip allowed?
bool bAllowClimbUp 
Is climbing up allowed here?
bool bAllowSwatTurn 
Is swat turn allowed?
bool bForceNoGroundAdjust 
if this is on ground adjustments will be skipped
bool bPlayerOnly 
Slot can only be used by players, not AI
bool bSelected 
Is this slot currently selected for editing?
int ExtraCost 
extra AI navigation cost to assign to this slot
float LeanTraceDist 
How far auto adjust code traces forward from lean fire point

to determine if the lean has a valid fire line

CoverSlotMarker SlotMarker 
Slot marker to allow the slot to exist on the navigation network
ECoverLocationDescription LocationDescription 
Per-slot description tag. If _None, fall back to the description in the CoverLink.
bool bFailedToFindSurface 
Map Error: Cover slot failed to find surface to align to

Default values:

Property Value
bAllowClimbUp False
bAllowCoverSlip True
bAllowMantle True

CovPosInfo[edit]

Modifiers: immutablewhencooked, native

Utility struct to reference a position in cover

CoverLink Link 
CoverLink holding cover position
int LtSlotIdx 
Index of left bounding slot
int RtSlotIdx 
Index of right bounding slot
float LtToRtPct 
Pct of distance Location is, between left and right slots
Object.Vector Location 
Location in cover
Object.Vector Normal 
Normal vector, used to define direction. Pointing from Location away from Wall.
Object.Vector Tangent 
Tangent vector, gives alignement of cover. With multiple slots cover, this gives the direction from Left to Right slots.
