I have a problem editing the cost of the path.
goal : I want the character to follow the path I have created . after the end of the road, it will go to the destination by the fastest route finding algorithm.
How to do : I changed the penalty .

the nodes make the path I set penalty = 1 . other nodes of the map I set penalty = 1000000.
so if you calculate the cost, the character will follow the path with a penalty of =1 .
result: the character still follows the shortest path through the cells with penalty = 1000000.
desired : character walking on nodes with penalty = 1

Hi

Would you mind posting the code that you are using?

What code do you mean? this is the code i use to handle the set penalty.
private void InitPointMap()
{
* List userBuildings = _userBuildingList.BuildingList;

        AstarPath.active.AddWorkItem((ctx =>

```
        {
```

            var gg = AstarPath.active.data.gridGraph;

            GraphNode[] nodes = gg.nodes;

            foreach (GraphNode node in nodes)

```
            {
```

                node.Penalty = (uint)10000000;

```
            }
```

            for (int i = 0; i < userBuildings.Count; i++)

```
            {
```

                int locationId = userBuildings[i].locationTileId;

                BuildingOperation buildingOperation = Utils.GetBuildingOperation(locationId, _buildingFinder);

                TilingTransform tilingTransform = Utils.GetTilingTransform(buildingOperation.BuildingObjId, _userBuildingList, _buildingFinder);

                NNInfo nodePos = _aStar.GetNearest(tilingTransform.GetLocalPosition());

                if(buildingOperation.BuildingId == 30101)

```
                {
```

                    foreach (GraphNode node in nodes)

```
                    {
```

                        if (node.NodeIndex == nodePos.node.NodeIndex)

                            node.Penalty = (uint)0;

```
                    }
```
```
                }
```
```
            }
```
```
        }));
  }
```
