Hey guys tried creating my first game today SNAKE
I have followed a tutorial on mooict which was really good only problem is that the game starts i see food but i cannot see the snack and Visual Studio is showing me no errors and help would be great as i was doing this to help my coding at college :D
Settings Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Snake_1
{
public enum Directions
{
Left,
Right,
Up,
Down,
};
class Settings
{
public static int Width { get; set; }
public static int Height { get; set; }
public static int Speed { get; set; }
public static int Score { get; set; }
public static int Points { get; set; }
public static bool GameOver { get; set; }
public static Directions direction { get; set; }
public Settings()
{
Width = 16;
Height = 16;
Speed = 20;
Score = 0;
Points = 100;
GameOver = false;
direction = Directions.Down;
}
}
}
Circle Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Collections;
using System.Windows.Forms;

{
class Circle
{
public int X { get; set; }
public int Y { get; set; }
public Circle()
{
X = 0;
Y = 0;
}
}
}
Input code
using System;

Form Code

else

}
}
private void startGame()

Circle head = new Circle { X = 10, Y = 5 };
Snake.Add(head);
label2.Text = Settings.Score.ToString();
generateFood();
}
private void generateFood()

Random rnd = new Random();

}
private void eat()
{
Circle body = new Circle

};
Snake.Add(body);
Settings.Score += Settings.Points;
label2.Text = Settings.Score.ToString();
generateFood();
}
private void die()
{
Settings.GameOver = true;
}
}
}
What I have tried:
Im new to coding so i have just been able to check over the tutorial and all seems fine had a go at trouble shooting myself but all appears okay i dont know if the code is updating graphics or i did something wrong.
Thank you for any help :D
