Add a connection from this node to the specified node.

Public
ClearConnections (alsoReverse)

Remove all connections between this node and other nodes.

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
ClosestPointOnNode (p)

Closest point on the surface of this node to the point p.

Public
ContainsOutgoingConnection (node)

True if this node contains a connection to the given 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<T> (action, data, connectionFilter)

Calls the delegate with all connections from or to this node, and passes a custom data value to the delegate.

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, pathNodeIndex, gScore)

Open the node.

Public
OpenAtPoint (path, pathNodeIndex, position, gScore)

Open the node at a specific point.

Public
ProjectOnSurface (point)

Projects the given point onto the plane of this node's surface.

Public
RandomPointOnSurface ()

A random point on the surface of the node.

Public
RemovePartialConnection (node)

Removes any connection from this node to the specified node.

Public
ResetConnectionsInternal ()

Disables all grid connections from this node.

Public Abstract
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.
