2,067 PointsThe name 'width' does not exist in the current context.
I thought my codes are as same as the ones written in the video, but the compiler said that "Map.cs(16,40): error CS0103: The name 'width' does not exist in the current context." How could I fix this error?
Game.cs
using System; namespace TreehouseDefense { class Game { public static void Main() { Map map = new Map(8, 5);
Point point = new Point(4, 2);
bool isOnMap = map.OnMap(point);
Console.WriteLine(isOnMap);
point = new Point(8, 5); //zero base counting
Console.WriteLine(isOnMap);
}
}
}
Map.cs namespace TreehouseDefense { class Map { public readonly int Width; public readonly int Height;
public Map(int width, int height)
{
Width = width;
Height = height;
}
public bool OnMap(Point point)
{
return point.X >= 0 && point.X < width &&
point.Y >= 0 && point.Y < height;
}
} }
Thanks a lot.

Remember that C# is case-sensitive, and the read-only instance variables of the Map object are Width and Height, both spelled with a capital first letter.
