Type members

• class var godotClassName: StringName

Instance members

• var cellSize: Vector2

  The size of the point cell which will be applied to calculate the resulting point position returned by getPointPath(fromId:toId:). If changed, update needs to be called before finding the next path.

• var defaultComputeHeuristic: AStarGrid2D.Heuristic

  The default Heuristic which will be used to calculate the cost between two points if _computeCost(fromId:toId:) was not overridden.

• var defaultEstimateHeuristic: AStarGrid2D.Heuristic

  The default Heuristic which will be used to calculate the cost between the point and the end point if _estimateCost(fromId:toId:) was not overridden.

• var diagonalMode: AStarGrid2D.DiagonalMode

  A specific DiagonalMode mode which will force the path to avoid or accept the specified diagonals.

• var jumpingEnabled: Bool

  Enables or disables jumping to skip up the intermediate points and speeds up the searching algorithm.

• var offset: Vector2

  The offset of the grid which will be applied to calculate the resulting point position returned by getPointPath(fromId:toId:). If changed, update needs to be called before finding the next path.

• var region: Rect2i

  The region of grid cells available for pathfinding. If changed, update needs to be called before finding the next path.

• var size: Vector2i

  The size of the grid (number of cells of size cellSize on each axis). If changed, update needs to be called before finding the next path.

• func clear()

  Clears the grid and sets the region to Rect2i(0, 0, 0, 0).

• func fillSolidRegion(Rect2i, solid: Bool)

  Fills the given region on the grid with the specified value for the solid flag.

• func fillWeightScaleRegion(Rect2i, weightScale: Double)

  Fills the given region on the grid with the specified value for the weight scale.

• func getIdPath(fromId: Vector2i, toId: Vector2i) -> VariantCollection<Vector2i>

  Returns an array with the IDs of the points that form the path found by AStar2D between the given points. The array is ordered from the starting point to the ending point of the path.

• func getPointPath(fromId: Vector2i, toId: Vector2i) -> PackedVector2Array

  Returns an array with the points that are in the path found by AStarGrid2D between the given points. The array is ordered from the starting point to the ending point of the path.

• func getPointPosition(id: Vector2i) -> Vector2

  Returns the position of the point associated with the given id.

• func getPointWeightScale(id: Vector2i) -> Double

  Returns the weight scale of the point associated with the given id.

• func isDirty() -> Bool

  Indicates that the grid parameters were changed and update needs to be called.

• func isInBounds(x: Int32, y: Int32) -> Bool

  Returns true if the x and y is a valid grid coordinate (id), i.e. if it is inside region. Equivalent to region.has_point(Vector2i(x, y)).

• func isInBoundsv(id: Vector2i) -> Bool

  Returns true if the id vector is a valid grid coordinate, i.e. if it is inside region. Equivalent to region.has_point(id).

• func isPointSolid(id: Vector2i) -> Bool

  Returns true if a point is disabled for pathfinding. By default, all points are enabled.

• func setPointSolid(id: Vector2i, solid: Bool)

  Disables or enables the specified point for pathfinding. Useful for making an obstacle. By default, all points are enabled.

• func setPointWeightScale(id: Vector2i, weightScale: Double)

  Sets the weightScale for the point with the given id. The weightScale is multiplied by the result of _computeCost(fromId:toId:) when determining the overall cost of traveling across a segment from a neighboring point to this point.
