Problem is not reproducible or outdated
InvalidOperationException thrown
I'm having issues with the following code, which is throwing an Invalid Operation Exception
if (nodeToAdd.nodeCoord != AStarSets.closedSet.First(a => a.nodeCoord == nodeToAdd.nodeCoord).nodeCoord)
{
if (nodeToAdd.nodeCoord == AStarSets.openSet.First(a => a.nodeCoord == nodeToAdd.nodeCoord).nodeCoord)
{
if (currentHex.GetComponent<HexObject>().hexObjectValuesOut.gValue > Math.Abs(((int)nodeToAdd.nodeCoord.x - x) + ((int)nodeToAdd.nodeCoord.y - y)))
{
getGCost(nodeToAdd.nodeCoord);
currentHex.GetComponent<HexObject>().hexObjectValuesOut.setFValue();
nodeToAdd.nodeCost = currentHex.GetComponent<HexObject>().hexObjectValuesOut.fValue;
nodeToAdd.parentNode = parentNode;
AStarSets.openSet.Add(nodeToAdd);
}
}
}
This code throws the following exception:
InvalidOperationException: Operation is not valid due to the current state of the object
System.Linq.Enumerable.First[AStarNodes] (IEnumerable`1 source, System.Func`2 predicate, Fallback fallback)
System.Linq.Enumerable.First[AStarNodes] (IEnumerable`1 source, System.Func`2 predicate)

Any help will be much appreciated
