Function LayerGridGraph.GetNodes

void GetNodes (

System.Action<GraphNode>

action

)

Calls a delegate with all nodes in the graph.

This is the primary way of iterating through all nodes in a graph.

Do not change the graph structure inside the delegate.

var gg = AstarPath.active.data.gridGraph;

gg.GetNodes(node => {
// Here is a node
Debug.Log("I found a node at position " + (Vector3)node.position);
});
If you want to store all nodes in a list you can do this

var gg = AstarPath.active.data.gridGraph;

List<GraphNode> nodes = new List<GraphNode>();

gg.GetNodes((System.Action<GraphNode>)nodes.Add);


void GetNodes (

System.Func<GraphNode, bool>

action

)

Calls a delegate with all nodes in the graph until the delegate returns false.
