2D Runtime Walkable Node

General Grid graph
#1

Hello,

I’m trying to make Node Walkable at Runtime, it turns blue on the Scene View, but with black outline. So agent can’t walk through this nodes. How can i solve this?

Code:

	public class Tester : MonoBehaviour
	{
		private AstarPath _astar = null;
		private GridGraph _graph = null;

		private void Start()
		{
			_astar = AstarPath.active;
			_graph = _astar.data.gridGraph;
		}

		private void Update()
		{
			if (Input.GetMouseButtonDown(1))
			{
				Vector2 mousePosition = MousePosition.WorldValue;
				int x = (int)mousePosition.x;
				int y = (int)mousePosition.y;

				_astar.AddWorkItem(new AstarWorkItem(ctx =>
				{
					GraphNode node = _graph.GetNearest(mousePosition).node;
					node.Walkable = true;
					_graph.CalculateConnectionsForCellAndNeighbours(x, y);
				}));
			}
		}
	}

Hi

You need to pass the node’s X and Z coordinates in the grid, not the world coordinates.
Use

GridNode node = graph.GetNearest(mousePosition).node as GridNode;
node.Walkable = true;
graph.CalculateConnectionsForCellAndNeighbours(node.XCoordinateInGrid, node.ZCoordinateInGrid);
