Node used for the PointGraph. More...
Node used for the PointGraph.
This is just a simple point with a list of connections (and associated costs) to other nodes. It does not have any concept of a surface like many other node types.

virtual |
Add a connection from this node to the specified node.
If the connection already exists, the cost will simply be updated and no extra connection added.
Implements GraphNode.
|
virtual |
Remove all connections from this node.
alsoReverse | if true, neighbours will be requested to remove connections to this node. |
Implements GraphNode.
|
virtual |
Checks if this node has a connection to the specified node.

virtual |
Used to deserialize references to other nodes e.g connections.
Use the GraphSerializationContext.GetNodeIdentifier and GraphSerializationContext.GetNodeFromIdentifier methods for serialization and deserialization respectively.
Nodes must override this method and serialize their connections. Graph generators do not need to call this method, it will be called automatically on all nodes at the correct time by the serializer.

virtual |
Calls the delegate with all connections from this node.
You can add all connected nodes to a list like this
