cant figure this out!

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

namespace VideoGame
{
    class UserControlledSprite : Sprite
    {


        public UserControlledSprite(Texture2D textureImage, Vector2 position,
            Point frameSize, int collisionOffset, Point currentFrame, Point sheetSize,
            Vector2 speed)
            : base(textureImage, position, frameSize, collisionOffset, currentFrame,
            sheetSize, speed)
        {
        }

        public UserControlledSprite(Texture2D textureImage, Vector2 position,
            Point frameSize, int collisionOffset, Point currentFrame, Point sheetSize,
            Vector2 speed, int millisecondsPerFrame)
            : base(textureImage, position, frameSize, collisionOffset, currentFrame,
            sheetSize, speed, millisecondsPerFrame)
        {
        }
    }
}



This is the error I got......

'VideoGame.UserControlledSprite' does not implement inherited abstract member 'VideoGame.Sprite.direction.get'

maybe you need to implement the get method in your derived class

abstract methods you defined in the base class will have to be implemented in any subclasses eg public override ...

Your cpde defines this property an abstract:
        public abstract Vector2 direction
        {
            get;
        }
You must implement it in code  at (UserControlledSprite)
        private Vector2 GetDirection()
  {
   //return an object of type vector 2 based on your business logic
}
        public override Vector2 direction
        {
            get  GetDirection();
        }

Looking at your attached code you've defined direction property in Sprite abstract class and have also marked it as abstract. You will have to define this in the derived class.

If that was not the intent, you can remove abstract keyword on the property in the sprite abstract class.

Hi Admin

Please refer to Comment/Response 33658872 & 33682036 point the same thing. Either or both of these should be accepted.

I felt that both helped me because I implemented the get methods rockiroads suggested and also canceled the abstract in sprite.cs that novice novice suggested .They both helped me learn C# language better than Iknew before.
