Function MeshNode.AddPartialConnection

void AddPartialConnection (

GraphNode	node
uint	cost
bool	isOutgoing
bool	isIncoming

)

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.

AstarPath.active.AddWorkItem(new AstarWorkItem(ctx => {
// Connect two nodes
var node1 = AstarPath.active.GetNearest(transform.position, NNConstraint.None).node;
var node2 = AstarPath.active.GetNearest(transform.position + Vector3.right, NNConstraint.None).node;
var cost = (uint)(node2.position - node1.position).costMagnitude;
node1.AddPartialConnection(node2, cost, true, true);
node2.AddPartialConnection(node1, cost, true, true);

node1.ContainsOutgoingConnection(node2); // True

node1.RemovePartialConnection(node2);
node2.RemovePartialConnection(node1);
}));


Some graphs have a special representation for some connections which is more efficient. For example grid graphs can represent connections to its 8 neighbours more efficiently. But to use that efficient representation you'll need to call GridNode.SetConnectionInternal instead of this method.

void AddPartialConnection (

GraphNode	node	Node to add a connection to
uint	cost	Cost of traversing the connection. A cost of 1000 corresponds approximately to the cost of moving 1 world unit.
byte	shapeEdgeInfo	Info about how the edge is which edge on the shape of this node to use or Connection.NoSharedEdge if no edge is used. See Connection.PackShapeEdgeInfo(byte,byte,bool,bool,bool).

Add a connection from this node to the specified node.
