XNA 2D game tutorial - controllable sprite

1. Initialize keyboard state (continue from XNA 2D game tutorial-animated sprite)

public class Game1 : Microsoft.Xna.Framework.Game

    {

        GraphicsDeviceManager graphics;

        SpriteBatch spriteBatch;

        Texture2D character;

        Vector2 position = new Vector2(200, 200);

        Point frameSize = new Point(28, 41);

        Point currentFrame = new Point(1, 0);

        Point sheetSize = new Point(12, 8);

        int state = 2; // walk if keyboard pressed

        float speed = 5; 

        KeyboardState currentState;

        KeyboardState theKeyboardState;

        KeyboardState oldKeyboardState;

        TimeSpan nextFrameInterval = TimeSpan.FromSeconds((float)1 / 16);

------------------------------------------------------------------------------------------------------------------

protected override void Update(GameTime gameTime)

        {

            // Allows the game to exit

            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)

                this.Exit();

            currentState = Keyboard.GetState();

            theKeyboardState = Keyboard.GetState();

            if (state == 1) // means walking state

            {

                currentFrame.Y = 2;

                currentFrame.X++;

                if (currentFrame.X >= 12)

                    currentFrame.X = 0;

            }

            oldKeyboardState = theKeyboardState;

            base.Update(gameTime);

        }

2. Move and animate

    if (state == 1) // means walking state

            {

                currentFrame.Y = 2;

                currentFrame.X++;

                if (currentFrame.X >= 12)

                    currentFrame.X = 0;

            }

else if (state == 2) // means wait for keyboard input

           {

                currentFrame.Y = 0;

                currentFrame.X ++;

                if (currentFrame.X >= 12)

                    currentFrame.X = 0;

                if (currentFrame.Y >= 1)

                {

                    currentFrame.Y = 1;

                    position.Y = 200;

                    frameSize = new Point(28, 41);

                }

                if (currentState.IsKeyDown(Keys.Right))

                {

                    frameSize = new Point(28, 41);

                    position.Y = 200;

                    currentFrame.Y = 2;

                    currentFrame.X++;

                    if (currentFrame.X >= 12)

                        currentFrame.X = 0;

                    position.X += speed;

                }

                else if (currentState.IsKeyDown(Keys.Left))

                {

                    frameSize = new Point(28, 41);

                    position.Y = 200;

                    currentFrame.Y = 1;

                    currentFrame.X++;

                    if (currentFrame.X >= 12)

                      currentFrame.X = 0;

                    position.X -= speed;

                }

            }

3. Run the code

4. If we press right,

5. If we press left,

6. Create .exe file

Build>> Publish <project name>.žChoose the location. Finish

7. VS 2010 will create your application’s installer

8. You can install your application in other computer ( just click the setup.exe file)

9. Click Start>> All programs. You will find your application has been installed in your computer.
