int GetNearestNodeToPos(vector pos)

Returns a node index

int GetBestNodeForPosInWedge(vector tPos, vector startPos, number yaw, number minFov, number maxFov, number fovPenalty, number some_index, number steps_maybe)

vector GetNodePos(int nodeIndex)

int GetNodeCount()

bool GetNodeScriptData_Boolean(int nodeIndex, int otherNodeIndex)

void SetNodeScriptData_Boolean(int nodeIndex, int otherNodeIndex, bool value)

int GetAINScriptVersion()

Navmeshes

bool NavMesh_IsUpToDate()

vector ornull NavMesh_ClampPointForAI( vector point, entity npc )

Clamps a goal point to the NavMesh for a given AI. Uses AIs hull size as test extents

vector ornull NavMesh_ClampPointForAIWithExtents( vector pointToClamp, entity contextAI, vector extents )

Clamps a goal point to the NavMesh for a given AI. As extents increase in size more possible clamp positions become available, but too large and the clamped position may be very far from the original point.

vector ornull NavMesh_ClampPointForHull( vector pointToClamp, int hull )

Clamps a goal point to the NavMesh for a given hull

vector ornull NavMesh_ClampPointForHullWithExtents( vector pointToClamp, int hull, vector extents )

Clamps a goal point to the NavMesh for a given hull. As extents increase in size more possible clamp positions become available, but too large clamped position may be very far from the original point.

array<vector> NavMesh_GetNeighborPositions(vector point, int hull_maybe, int nNodesToCheck_maybe)

Get nearby ground positions by following the NavMesh graph

array<vector> NavMesh_RandomPositions(vector startPos, int hull, int numPositionsRequested, float minDist, float maxDist)

Get n( < 64 ) ground positions around a spot within minDist and maxDist

array<vector> NavMesh_RandomPositions_LargeArea(vector startPos, int hull, int numPositionsRequested, float minDist, float maxDist)

Get up to n ground positions around a spot within minDist and maxDist. Gets center of random polygons.

bool NavMesh_IsPosReachableForAI(entity npc, vector point)

Checks if the npc can reach the position over graph

vector GetBoundsMin(int hull)

vector GetBoundsMax(int hull)

Skits

void SkitSetDistancesToClosestHarpoints()

array<entity> GetSkitNodeArray_NearPlayers()

Get skit nodes sorted by nearest to average player position with some randomization

array<entity> GetSkitNodeArray_NearHardpoints()

Get skit nodes sorted by nearest to hardpoints with some randomization

array<entity> GetSkitNodeArray_NearPos()

Get skit nodes sorted by nearest to pos with some randomization

Dangerous Areas

void AI_CreateDangerousArea(entity lifetimeEnt, entity weaponOrProjectile, float radius, int safeTeam, bool affectsNormalArmor, bool affectsHeavyArmor)

Create a known dangerous are that AI should avoid if necessary. The lifetime of the danger is tied to an entity

void AI_CreateDangerousArea_Static(entity lifetimeEnt, entity weaponOrProjectile, float radius, int safeTeam, bool affectsNormalArmor, bool affectsHeavyArmor, vector staticOrigin)

Same as AI_CreateDangerousArea except the origin is always in a single place

void AI_CreateDangerousArea_DamageDef(int damageDef, entity lifetimeEnt, int safeTeam, bool affectsNormalArmor, bool affectsHeavyArmor)

Create dangerous area using damage def

Spawners

array<entity> GetSpawnerArrayByClassName(string className)

Get array of spawners matching a class name

array<entity> GetSpawnerArrayByScriptName(string name)

Get array of spawners matching a script name
