This piece of code listens to any changes in my Firebase and fires HandleListChange() when it detects a change:
void SetRoomListListener()
{
FirebaseDatabase.DefaultInstance
.GetReference ("Rooms")
.ValueChanged += HandleListChange;
}
My HandleListChange()
looks like this at the moment:
void HandleListChange(object sender, ValueChangedEventArgs args)
{
if (args.DatabaseError != null) {
Debug.LogError (args.DatabaseError.Message);
return;
}
// We got the new data
foreach (DataSnapshot room in args.Snapshot.Children)
{
string roomName = room.Key;
foreach (KeyValuePair<string, Object> info in room.Value)
{
Debug.Log (info);
}
}
}
Debugging room.Key
gives me name of the room as I want it and room.Value
returns some kind of dictionary -> Dictionary2[System.String, System.Object]
. I want to access a value in that Dictionary using a key let's say room.Value["size"]
but I get this error from the foreach-loop foreach statement cannot operate on variables of type object because it does not contain a definition for GetEnumerator or is inaccessible
. I've tried quite a few other methods but can't get this to work. This is my first time working with both: directories and firebase, so I have no clue whats going on. Firebase API for Unity is quite minor and internet is not helping much either. I guess this problem is more likely on the C# side, not on Unity's or Firebase's. How can I access my values using a key in that directory? Thanks.
From the documentation it seems that DataSnapshot.Value
returns an object
, which may encapsulate different native types.
If you are sure room.Value
contains a dictionary, then you should just cast it and then access its members like any dictionary in C#:
var dictionary = (IDictionary<string, object>)room.Value;
var exampleValue = dictionary["size"];
