We want to apply the layergridgraph to the procedural voxel map we are creating. In layergridgraph, however, it is not possible to acquire nodes using world coordinate.
Is there a way to get this fast? Or should I change the array structure of the node?
If you just want to get the closest node to a world coordinate then you can use AstarPath.active.GetNearest(point).
If you want to get the node using a grid coordinate then you can use LayerGridGraph.GetNode(x,z,layer).
