public static void ExilePather.BlockTriggerableBlockages(ref byte[] data, int bytesPerRow, Func<NetworkObject, bool> shouldBlock, List<NetworkObject> obj)Sets a blockage's observed footprint to zero clearance (predicate true) or restores its original clearance (predicate false). Does not open or close the object in the game or turn surrounding walls into walkable cells. Empty bounds contain no cells and are ignored without interrupting the remaining objects.
databyte[]bytesPerRowintshouldBlockFunc<NetworkObject, bool>objList<NetworkObject>When data is the active LokiPoe.TerrainData.Cache.Data buffer, call UpdateObstacles once after batching edits. It rebuilds the global mesh only if cells changed, preserving temporary obstacles and their handles. Explicit choices take priority over automatic blockage updates for this cached terrain. A forced Reload(true) or terrain recache reads a new game buffer; reapply the choices afterwards if still required. Edits to a separate byte array do not affect the global Pathfinder. The footprint must first be observed while the object is closed. An already-open object's buffer is not a mask; if its closed footprint is unknown this method reports the missing data instead of altering the whole rectangle.
public static bool ExilePather.CanObjectSee(Vector2i start, Vector2i end, out Vector2i hitPoint, bool dontLeaveFrame = false, bool shouldUseRangedMap = false)Convenience wrapper over DreamPoeBot.Loki.Bot.Pathfinding.ExilePather.Raycast(DreamPoeBot.Common.Vector2i,DreamPoeBot.Common.Vector2i,DreamPoeBot.Common.Vector2i@,System.Boolean,System.Boolean).

public static void ExilePather.ClearObstacles()Clears all temporary obstacles from the tile cache.
Also calls DreamPoeBot.Loki.Bot.Pathfinding.ExilePather.UpdateObstacles to ensure the tile cache is up to date.
public static void ExilePather.ClearWalkablePositionCache()Clears walkable position cache.
public static Vector2i ExilePather.FastWalkablePositionFor(Vector2i pos, int range = 30, bool cache = true)Finds a nearby walkable position around pos within range.
posVector2irangeintcacheboolReturns: A walkable position, or DreamPoeBot.Common.Vector2i.Zero if none found.
public static Vector2i ExilePather.FastWalkablePositionFor(NetworkObject obj, int range = 30, bool cache = true)Finds a nearby walkable position around obj within range.
objNetworkObjectrangeintcacheboolReturns: A walkable position, or DreamPoeBot.Common.Vector2i.Zero if none found.
public static List<Vector2i> ExilePather.GetPointsOnSegment(Vector2i start, Vector2i end, bool dontLeaveFrame)Returns all integer grid points along the straight line from start to end (inclusive). Uses Bresenham-style rasterization.
startVector2iendVector2idontLeaveFrameboolReturns: Ordered list of grid points from start to end.
public static bool ExilePather.IsWalkable(Vector2i arg)Returns whether arg lies on a walkable navmesh polygon.
argVector2iReturns: true if walkable; otherwise false.
public static bool ExilePather.IsWalkable(int x, int y)Returns whether the position (x, y) lies on a walkable navmesh polygon.
xintyintReturns: true if walkable; otherwise false.
public static float ExilePather.PathDistance(Vector2i start, Vector2i end)Returns the distance of the path between two points.
startVector2iendVector2iReturns: Path length in world units, or System.Single.MaxValue if no path exists.
public static bool ExilePather.PathExistsBetween(Vector2i start, Vector2i end)Returns true if a path exists between start and end using the current navmesh.
startVector2iendVector2iReturns: A Boolean result. The member description explains the condition being checked.
public static bool ExilePather.Raycast(Vector2i start, Vector2i end, out Vector2i hitPoint, bool dontLeaveFrame = false, bool shouldUseRangedMap = false)Project a ray from start to end, if the ray encounter a non walkable location or an obstacle, it return false and out the location of the obstacle as hitpoint. This function do not consider dynamic objects (object collected with Objectmanager, like doors, chests, monsters etc).
startVector2iendVector2ihitPointVector2idontLeaveFrameboolshouldUseRangedMapboolReturns: Return true if the function do not encounter any obstacle, or false if a obstacle is encountered.
This function also Broadcast a message with id "Raycast_Result" and has 4 parms as input: Vector2i start, Vector2i end, bool Returnvalue, Vector2i hitPoint. If ground map is used, detour's raycast is used which is generally a lot faster.
public static bool ExilePather.Raycast(Vector2i start, Vector2i end, List<NetworkObject> objectsToConsider, out Vector2i hitPoint, out int objectId, bool dontLeaveFrame = false, bool shouldUseRangedMap = false)Project a ray from start to end, if the ray encounter a non walkable location or an obstacle, it return false and out the location of the obstacle as hitpoint, and Object Id in cast the obstacle is an NetworkObject. This function account for a given list of NetworkObjects to include in the calculation. This function account for the interactsize of the networkobject, so the hitboz is considered.
startVector2iendVector2iobjectsToConsiderList<NetworkObject>hitPointVector2iobjectIdintdontLeaveFrameboolshouldUseRangedMapboolReturns: Return true if the function do not encounter any obstacle, or false if a obstacle is encountered.
public static bool ExilePather.RaycastPf(Vector2i start, Vector2i end, out Vector2i hitPoint)Raycast directly via navmesh wrapper. Returns true if no blocking obstacle. Only works for ground level mesh.
startVector2iendVector2ihitPointVector2iReturns: True if no obstacle was encountered.
public static void ExilePather.Reload(bool force = false)Synchronously (re)loads navmesh and height map for the current area and applies dynamic obstacles. When the game is not ready, returns without rebuilding and leaves IsReady false.
forceboolpublic static Task ExilePather.ReloadAsync(bool force = false, CancellationToken ct = default(CancellationToken))Asynchronously (re)loads navmesh and height map for the current area and applies dynamic obstacles. When the game is not ready, completes without rebuilding and leaves IsReady false.
forceboolctCancellationTokenReturns: A task that completes when the reload finishes or is canceled.
public static bool ExilePather.RemoveObstacle(uint obstacleRef)Removes an obstacle by its reference ID.
obstacleRefuintReturns: True if removal was successful

public static bool ExilePather.UpdateObstacles()Applies pending blockage terrain edits and temporary obstacles to the global navigation mesh. Call once after batching edits. Terrain changes require a full mesh rebuild; ordinary obstacle updates only rebuild affected tiles.
