Rectangle contains Point returns false

Question

I am making a simple Pacman game using c# in Visual studio. I decided to make a rectangles of a maze in which the main character can walk. I have a rectangle which covers main character's bounds:

Rectangle _pacmanBound = new Rectangle(Left, Top, 28, 28);

Then I take the 4 points of this rectangle (top left, bottom left, top right and bottom right). I also have a List with rectangle areas in which pacman can walk:

map = new List<Rectangle>();

map.Add(new Rectangle(12, 375, 430, 28)); 
map.Add(new Rectangle(12, 403, 28, 97)); 
map.Add(new Rectangle(12, 470, 430, 28));

Now I want to check if all these 4 points belong to any of the rectangles in a list (so it indicates that the area is walkable):

foreach (Rectangle r in _maze.map)
{
    if (r.Contains(_pacmanBound.X, _pacmanBound.Y))
    {
        topLeft = true;

    }
    else if (r.Contains(_pacmanBound.X, _pacmanBound.Y + _pacmanBound.Height))
    {
        bottomLeft = true;    
    } 
    else if (r.Contains(_pacmanBound.X + _pacmanBound.Width, _pacmanBound.Y))
    {
        topRight= true;
    } 
    else if (r.Contains(_pacmanBound.X + _pacmanBound.Width, _pacmanBound.Y + _pacmanBound.Height))
    {
        bottomRight = true;
    }
}

After loop the first one is true, second - false, third - false and fourth = false

To let you better understand, I add this picture:

Any help is appreciated.

Answer 1

Your problem is that you're using else clause. So, if the first if clause is true, the program will not check other if clauses. You need to remove else clause:

foreach (Rectangle r in _maze.map)
{
            if (r.Contains(_pacmanBound.X, _pacmanBound.Y))
            {
                topLeft = true;

            }
            if (r.Contains(_pacmanBound.X, _pacmanBound.Y + _pacmanBound.Height))
            {
                bottomLeft = true;

            }
            if (r.Contains(_pacmanBound.X + _pacmanBound.Width, _pacmanBound.Y))
            {
                topRight= true;

            }
            if (r.Contains(_pacmanBound.X + _pacmanBound.Width, _pacmanBound.Y + _pacmanBound.Height))
            {
                bottomRight = true;
            }
}

Also, you don't have to check each point of pacman rectangle. You can just check, if map rectangle contains pacman rectangle:

foreach (Rectangle r in _maze.map)
{
    if (r.Contains(_pacmanBound))
    {
        isPacmanInsideMaze = true;
        break;
    }
}
