Deleted key values pairs being restored in the custom room hash table for the current room???

ManjitB

Much to my surprise this seems to be happening:

• I add a key value pair to hold some game state
• I later delete the key value pair
• I kept playing along when testing a multiplayer session
• the key value pairs that should be deleted came back somehow
• game is messed up - oops

My first question is are there any known issue with using the the custom properties hash table for the current room?

Second question how can I ensure the date is deleted. Here is my method to update the hash table:

    /// <summary>
    /// Remove a key value pair from the state.
    /// This method will remove pair from the local hash table and the Photon network.
    /// </summary>
    /// <param name="key"></param>
    private void SyncStateRemove(string key)
    {
      // To remove the property you need to set the property to null.
      PhotonHashTable table = new PhotonHashTable() { { key, null } };
      PhotonNetwork.CurrentRoom.SetCustomProperties(table);

      if (mapProperties.ContainsKey(key))
      {
        mapProperties[key] = null;
      }
    }

Hi @ManjitB,

Make sure RoomOptions.DeleteNullProperties is true (default) when creating rooms.

      if (mapProperties.ContainsKey(key))
      {
        mapProperties[key] = null;
      }

This snippet should not be needed.

Instead you need to wait until OnRoomPropertiesUpdate is called.

Is this a bug? Intellisense says it defaults to false:

We are using version 2.40.

Hi @ManjitB,

My bad then set it to true.

I thought it was true by default.
