Choosing a graph to path-find on

Beginner Questions
1

Hi, Just wondering how I define which graph to path-find on?

Looks like I can create multiple graphics within 1 scene, but not sure how to determine what graph my character will use.
Right now I’ve got 2 graphs, 1 for large objects, 1 for small.

That can be done via the NNConstraint’s graphMask variable: http://arongranberg.com/astar/docs/class_pathfinding_1_1_n_n_constraint.php#a63a785ae519f012d295916dd9969170c

When you start a new path in your movement script, you will have to do something like this:
//Start a path which can only start and end on the second and third graph. Path p = new Path (startPoint, endPoint); p.nnConstraint.graphMask = 1 << 1 | 1 << 2; mySeeker.StartPath (p);
