Why is the position of my object different from the field of object?

• C# - Adding condition to func results in stack overflow exception

  I have a func as part of specification class which sorts the given iqueryable

  Func<IQueryable<T>, IOrderedQueryable<T>>? Sort { get; set; }
  

  When i add more than one condition to the func like below , it results in stack overflow exception.

  spec.OrderBy(sc => sc.Case.EndTime).OrderBy(sc => sc.Case.StartTime);
  

  The OrderBy method is implemented like this

  public ISpecification<T> OrderBy<TProperty>(Expression<Func<T, TProperty>> property)
      {
          _ = Sort == null ? Sort = items => items.OrderBy(property) : Sort = items => Sort(items).ThenBy(property);
          return this;
      }
  

  Chaining or using separate lines doesn't make a difference.

  This problem gets resolved if I assign a new instance of the specification and set it's func, but i don't want to be assigning to a new instance everytime. Please suggest what am i missing here and how to reuse the same instance (if possible).
• How to projection fields for a dictionary (C#, MongdoDB)

  I am trying my luck here, I have a model which is like the following

  public class RowData : BaseBsonDefinition
  {
  .
    [BsonExtraElements]
    [BsonDictionaryOptions(DictionaryRepresentation.ArrayOfDocuments)]
    public Dictionary<string, object> Rows { get; set; } = new(StringComparer.OrdinalIgnoreCase);
  .
  }
  
  

  In result, the schema in the MongoDB looks like

  {
  "_id": {
      "$binary": {
        "base64": "HiuI1sgyT0OZmcgGUit2dw==",
        "subType": "03"
      }
    },
    "c1": "AAA",
    "c8": "Fully Vac",
    "c10": "",
  }
  

  Those c1, c8 and c10 fields are keys from the dictionary, my question is how to dynamic project those fields?

  I tried

  Builders<RowData>.Projection.Exclude(p => "c1")
  

  It seems the MongoDB driver can not handle a value directly.

  Anyone could point me in the correct direction?

• How do I add new DataSource to an already Databinded CheckBoxList

  i'm building a web form that show Database's item(Tables, Rows, FK,...)

  I have a CheckBoxList of Tables (chkListTable) which will show a new CheckBoxList of Rows (chkListRow) everytime I SelectedIndexChanged from chkListTable. The problem is i can show the items from chkListTable with 1 selected item. But i don't know how to show chkListRow if multiple item from chkListTable are selected.

  Here are my codes:

• C# MariaDB Update Function working in DataStore but not updating in .NET Application

  My initial issue is that my database does not update when I call on this specific code. I am not sure if it is C# itself or the update query that I am calling.

  string _connectionString = "validConnectionstring";
  
  using (MySqlConnection _mySqlConnection = new MySqlConnection(_connectionString)
  {
  _mySqlConnection.Open();
  using (MySqlCommand command = new MySqlCommand("UpdateProfileStatus", _mySqlConnection))
  {

      command.CommandType = CommandType.StoredProcedure;
      command.Parameters.AddWithValue("@_username", "test");
      command.Parameters.AddWithValue("@_status", true);
      command.ExecuteNonQuery();
      
  }
  _mySqlConnection.Close();
  }
  
  

  I get no updates in my database but my console logs that the query is executed returning the value of 1 but there is no update that actually happens in my DB. Is there something in my code to reason why it is failing?

  Here is the stored procedure that I have for the update command

  CREATE PROCEDURE UpdateProfileStatus(_username VARCHAR(25), _status BOOL)
  UPDATE Profile SET status = _status WHERE username = _username;
  
  
  

  I know the Stored Procedure works but am not sure why my .NET application is not responding to my procedure call. Is it something to do with my implementation of the parameters or is it my procedure itself?

• How can I programmatically "step" through a scene playthrough for identical playback in Unity? (pixel perfect frame replay)

• error CS1061: 'Animator' does not contain a definition for 'SetInt' and no accessible extension method 'SetInt'

  so I'm having this error above in Unity and I don't know how to solve it.

  The error from what I understand is in the switch, it's probably not getting the animator and blocking me from setting the animation value.

  I searched on google and ended up not understanding very well, if anyone can help me I would appreciate it

     public class Pontos : MonoBehaviour
  {
      public static Animator BluePoint, RedPoint;
      public static int Score;
  
      void Start()
      {
         BluePoint = GameObject.Find("Azul_Icons").GetComponent<Animator>();

              case (1):

              Debug.Log("Score = 1");
              break;
  
              case (2):
              BluePoint.SetInt("AzulValor", 2);
              Debug.Log("Score = 2");
              break;
  
              case (3):
              BluePoint.SetInt("AzulValor", 3);
              Debug.Log("Score = 3");
              break;
              
          }
      }
  }
  

  To give a better example, this code is my points table (it's not perfect because I'm still testing it).

  In void Test, don't worry about "PlayerAzul" (class) and "BlueShoot" (bool) , they are from another script that is working fine.

• What is a sensor in the context of the Blender game engine?

  What's a sensor in the context of the Blender game engine?

  1. it's something that connects an input to an output

  2. it's something that listens for various events

  3. it's something that controls an object or part of the scene

  or all 3 of them?
• Count Rotations in unity 2d game

  I am making a game in which the character falls down on a slope and is constantly rotating clockwise at a fixed rotation. If it lands on it's feet it jumps.

  The question is how to count a full spin(360) after touching the ground and how to multiply the jumping power for each complete spin, for ex. if the player manages to have a full spin and lands on its feet then the jumpower will be multiplied by X, if it manages two spins it will be multiplied by Y... and so on, but when it fails and touches the ground with other parts of the body I need to also reset the jumppower to initial value.

  I tried using eulerAngles, but it doesn't work... Also I want to have a counter on screen that can show the user how many rotations has got after jumping and resetting when touching the ground, if its possible, I am new into unity and any help will be deeply appreciated.

  This is the code that I used for counting rotations(also found on stackoverflow):

  private void Start()
  {
      rigidBody = GetComponent<Rigidbody2D>();
      previousRollAngle = rigidBody.transform.eulerAngles.x;
  }
  private void FixedUpdate()        
  {
  
      IsTouchingGround = Physics2D.OverlapCircle(groundCheckPoint.position, groundCheckRadius, GroundLayer);
      if (IsTouchingGround)
      {
          rigidBody.velocity = transform.up * JumpPower;
      }
  
      //rigidBody.velocity = new Vector2(rigidBody.velocity.x, JumpPower);
      // direction = rigidBody.transform.direction
      // GetComponent<Rigidbody2D>().AddRelativeForce(new Vector2(0, JumpPower),ForceMode2D.Impulse);
  
      //countspins
      if (rollDegree >= 360)
      {
          rollDegree = rollDegree - 360;
          leftSpins++;
      }
      else if (rollDegree <= -360)
      {
          rollDegree = rollDegree + 360;
          rightSpins++;
      }
      rollDegree = rollDegree + (rigidBody.transform.eulerAngles.x - previousRollAngle);
      previousRollAngle = rigidBody.transform.eulerAngles.x;
  
      if (rightSpins == 1)
      {
          JumpPower = JumpPower * 3;
      }
  }
  

  And this is the code that I used for rotating the player:

  void Update()
  {
      GetComponent<Rigidbody2D>().angularVelocity = Spin;
      if (Input.GetKey(KeyCode.Space))
      {
          GetComponent<Rigidbody2D>().angularVelocity = CtrSpin;
      }
  

  Also I added an image with an example to be more clear
