Class GridNodeBase Extends GraphNode

Public Abstract

Base class for GridNode and LevelGridNode.

Public Methods

AddConnection (node, cost)

Add a connection from this node to the specified node.

Public
ClearConnections (alsoReverse)

Remove all connections from this node.

Public
ClearCustomConnections (alsoReverse)

Same as ClearConnections, but does not clear grid connections, only custom ones (e.g added by AddConnection or a NodeLink component)

Public
ContainsConnection (node)

Checks if this node has a connection to the specified node.

Public
ContainsPoint (point)

Checks if point is inside the node when seen from above.

Public
ContainsPointInGraphSpace (point)

Checks if point is inside the node in graph space.

Public
DeserializeReferences (ctx)

Used to deserialize references to other nodes e.g connections.

Public
GetConnections (action)

Calls the delegate with all connections from this node.

Public
GetGizmoHashCode ()

Hash code used for checking if the gizmos need to be updated.

Public
GetNeighbourAlongDirection (direction)

Adjacent grid node in the specified direction.

Public Abstract
HasConnectionInDirection (direction)

True if the node has a connection to an adjecent node in the specified direction.

Public
NormalizePoint (worldPoint)

Transforms a world space point to a normalized point on this node's surface.

Public
Open (path, pathNode, handler)

Open the node.

Public
RandomPointOnSurface ()

A random point on the surface of the node.

Public
RemoveConnection (node)

Removes any connection from this node to the specified node.

Public
SerializeReferences (ctx)

Used to serialize references to other nodes e.g connections.

Public
SurfaceArea ()

The surface area of the node in square world units.

Public
UnNormalizePoint (normalizedPointOnSurface)

Transforms a normalized point on this node's surface to a world space point.

Public
UpdateRecursiveG (path, pathNode, handler)
Public

Public Static Methods

OppositeConnectionDirection (dir)

The connection oppositie the given one.
