keep track of a trail in csharp

To keep track of a trail in C#, you can use a data structure to store the coordinates of each point on the trail. One way to do this is to create a custom Point class with x and y properties, and then create a List<Point> to store the trail.

main.cs
public class Point
{
    public int x { get; set; }
    public int y { get; set; }
}

List<Point> trail = new List<Point>();

8 lines

To add a new point to the trail, you can create a new Point object and add it to the list:

main.cs
Point newPoint = new Point { x = 10, y = 20 };
trail.Add(newPoint);

You can then use the list of points to draw the trail on a map or display other information about the trail.

To make the trail tracking more efficient, you can use algorithms such as the Douglas-Peucker algorithm to reduce the number of points in the trail by removing those that are close to a straight line. This can help to simplify the data and make it easier to work with.
