Struct PathRequestSettings

GraphMask graphMask

Graphs that this Seeker can use.

This field determines which graphs will be considered when searching for the start and end nodes of a path. It is useful in numerous situations, for example if you want to make one graph for small units and one graph for large units.

This is a bitmask so if you for example want to make the agent only use graph index 3 then you can set this to: seeker.graphMask = 1 << 3;


Note that this field only stores which graph indices that are allowed. This means that if the graphs change their ordering then this mask may no longer be correct.

If you know the name of the graph you can use the Pathfinding.GraphMask.FromGraphName method: GraphMask mask1 = GraphMask.FromGraphName("My Grid Graph");
GraphMask mask2 = GraphMask.FromGraphName("My Other Grid Graph");

NNConstraint nn = NNConstraint.Walkable;

nn.graphMask = mask1 | mask2;

// Find the node closest to somePoint which is either in 'My Grid Graph' OR in 'My Other Grid Graph'
var info = AstarPath.active.GetNearest(somePoint, nn);
Some overloads of the #StartPath methods take a graphMask parameter. If those overloads are used then they will override the graph mask for that path request.

int[] tagPenalties

The penalty for each tag.

If null, all penalties will be treated as zero. Otherwise, the array should always have a length of exactly 32.

int traversableTags

The tags which the Seeker can traverse.

ITraversalProvider traversalProvider

Filters which nodes the agent can traverse, and can also add penalties to each traversed node.

In most common situations, this is left as null (which implies the default traversal provider: DefaultITraversalProvider). But if you need custom pathfinding behavior which cannot be done using the graphMask, tagPenalties and traversableTags, then setting an ITraversalProvider is a great option. It provides you a lot more control over how the pathfinding works.
