title: Collision detection and stop movement
body: <p>I am making a simple game. I managed to make my character move with arrow keys and fire. I added some walls to the map which are pictureboxes. I managed to detect the collision like this:</p>
  
  <pre><code>private void timer6_Tick(object sender, EventArgs e){
      foreach (PictureBox pic in brick){
          if (pic.Bounds.IntersectsWith(pb_sprite.Bounds)){
              Console.WriteLine("Colision!");
              switch (rotation){
                  case "up":
                      canup = false;
                      candown = true;
                      canleft = true;
                      canright = true;
                      break;
                  case "down":
                      canup = true;
                      candown = false;
                      canleft = true;
                      canright = true;
                      break;
                  case "left":
                      candown = true;
                      canup = true;
                      canleft = false;
                      canright = true;
                      break;
                  case "right":
                      candown = true;
                      canup = true;
                      canleft = true;
                      canright = false;
                      break;
               }
          }
          else
          {
              Console.WriteLine("No colision?!");
          }
      }
  }
  </code></pre>
  
  <p>It works as expected but soon as I hit the object (wall) I get "Colision!" echo which is ok, this also stops movement in the direction which the character was facing when the collision occurred. The thing is when I exit the collision one of these bools stays false which prevents my character to move again in the same direction. I tried setting all of these bools to true in else branch but since there are five walls even if there is collision else branch gets executed 4 times out of 5. I need some kind of "any" function to check if NO or ANY walls are being hit at one moment.</p>
