Figuratively speaking, there is an image of a tank that can move in any direction using the arrow buttons on the keyboard + the picture of the tank does not crawl over the edges (stops at the edge) + while the picture itself rotates, but I have manually drawn obstacles ( not a picture ) and it is necessary that when it touches the obstacles to stop

below the code as it goes and stops in front of the window + turns (not perfect but in my version works as it should)

if (e.Key == Key.Up) { TransformGroup tg; System.Windows.Media.RotateTransform rt; tg = image.RenderTransform as System.Windows.Media.TransformGroup; if (tg == null) { tg = new System.Windows.Media.TransformGroup(); image.RenderTransform = tg; } rt = tg.Children.FirstOrDefault(x => x is System.Windows.Media.RotateTransform) as System.Windows.Media.RotateTransform; if (rt == null) { rt = new System.Windows.Media.RotateTransform(); tg.Children.Add(rt); } rt.Angle = 90; } if (e.Key == Key.Right) { TransformGroup tg; System.Windows.Media.RotateTransform rt; tg = image.RenderTransform as System.Windows.Media.TransformGroup; if (tg == null) { tg = new System.Windows.Media.TransformGroup(); image.RenderTransform = tg; } rt = tg.Children.FirstOrDefault(x => x is System.Windows.Media.RotateTransform) as System.Windows.Media.RotateTransform; if (rt == null) { rt = new System.Windows.Media.RotateTransform(); tg.Children.Add(rt); } rt.Angle = 180; } if (e.Key == Key.Down) { TransformGroup tg; System.Windows.Media.RotateTransform rt; tg = image.RenderTransform as System.Windows.Media.TransformGroup; if (tg == null) { tg = new System.Windows.Media.TransformGroup(); image.RenderTransform = tg; } rt = tg.Children.FirstOrDefault(x => x is System.Windows.Media.RotateTransform) as System.Windows.Media.RotateTransform; if (rt == null) { rt = new System.Windows.Media.RotateTransform(); tg.Children.Add(rt); } rt.Angle = -90; } if (e.Key == Key.Left) { TransformGroup tg; System.Windows.Media.RotateTransform rt; tg = image.RenderTransform as System.Windows.Media.TransformGroup; if (tg == null) { tg = new System.Windows.Media.TransformGroup(); image.RenderTransform = tg; } rt = tg.Children.FirstOrDefault(x => x is System.Windows.Media.RotateTransform) as System.Windows.Media.RotateTransform; if (rt == null) { rt = new System.Windows.Media.RotateTransform(); tg.Children.Add(rt); } rt.Angle = 360; } if (e.Key == Key.Left) if (image.Margin.Left > 10) image.Margin = new Thickness(image.Margin.Left - 15, image.Margin.Top, 0, 0); else image.Margin = new Thickness(image.Margin.Left, image.Margin.Top, 0, 0); if (e.Key == Key.Right) if (image.Margin.Left < 1230) image.Margin = new Thickness(image.Margin.Left + 15, image.Margin.Top, 0, 0); else image.Margin = new Thickness(image.Margin.Left, image.Margin.Top, 0, 0); if (e.Key == Key.Up) if (image.Margin.Top > 50) image.Margin = new Thickness(image.Margin.Left, image.Margin.Top - 15, 0, 0); else image.Margin = new Thickness(image.Margin.Left, image.Margin.Top, 0, 0); if (e.Key == Key.Down) if (image.Margin.Top < 660) image.Margin = new Thickness(image.Margin.Left, image.Margin.Top + 15, 0, 0); else image.Margin = new Thickness(image.Margin.Left, image.Margin.Top, 0, 0);

Please make a sample code !!!

    You should separate the content from the presentation. Create an internal representation of the field and objects, with each step, check its possibility. In short, you need to write a lot more. - VladD

Well, here's an example.

 public void Move(ref int x, ref int y, int a, bool[][]map) { int nX = x + (a == 1 ? -1 : a == 3 ? 1 : 0); int nY = y + (a == 2 ? 1 : a == 4 ? -1 : 0); if(nX>=0 && nX<map.length) if(nY>=0 && nY<map[nX].length) if (!map[nX][nY]) { x = nX; y = nY; } }

PS:

a : 1-Left; 2-up; 3-right; 4-Down;

map : obstacle map;
