This month we`ll discuss about the code and steps to use XBOX360 controller in a XBOX360 game.

XBOX360 Controller

 

Xbox360 game screen.            

In the Game1.cs file initialize these variables.

SpriteFont myfont;//add a sprite font to draw String   in the screan

Texture2D mytx;//creating texture object

Color mycolor;//define a color variable

float Position = 0.0f;//initializing left right position

float Position2 = 0.0f;//initializing up down position

Now in the LoadContent() method write code to load the assert.

 

  mytx = Content.Load<Texture2D>("pic");

  myfont = Content.Load<SpriteFont>("Arial");

 

 

Then in the Update() method you can check for XBOX360 Contraller Inputs

 

 

GamePadState state = GamePad.GetState(PlayerIndex.One);

 //capturing the plyer one XBOX360 Controller state

     

    float moveFactorPerSecond = 80 *

   (float)gameTime.ElapsedRealTime.TotalMilliseconds / 1000.0f; // Move 400 pixels each second

 

  // Allows the game to exit

   if (state.Buttons.Back == ButtonState.Pressed)

   this.Exit();

  //A Buttons

   if (state.Buttons.A == ButtonState.Pressed)

   {

           mycolor = Color.Red;

        //Set vibration

           GamePad.SetVibration(0, 4f, 3f);

    }

   else

     {

            mycolor = Color.White;       

     }          

    //Direction Pad

      if( state.DPad.Left == ButtonState.Pressed)

      {

          Position -= moveFactorPerSecond;

      }

 

     if( state.DPad.Right == ButtonState.Pressed)

      {

          Position += moveFactorPerSecond;      

      }

     

      if(state.DPad.Up == ButtonState.Pressed)

      {

          Position2 -= moveFactorPerSecond;

      }

      

      if (state.DPad.Down == ButtonState.Pressed)

      {

           Position2 += moveFactorPerSecond;     

      }

    

 

In the Draw () method you can see the Changes of the inputs by drawing the images.

spriteBatch.Begin(); //start process

 

spriteBatch.Draw(mytx, new Vector2(100f+Position, 100f+Position2), mycolor);

 //setting position with variables (Position1) and (Position2)

 //those variables change the position of the image according to the key pressing

           

 

 spriteBatch.DrawString(myfont, "Use D Pad to move the image  and Press A for change the color",new Vector2(10f,10f),Color.Yellow);

       //drawing text on the screan

 

spriteBatch.End(); //end process

 

 

Now you can run the project by pressing F5 or by clicking the run button.

Coding for Other Buttons.

      // ABXY buttons

        public static bool BButton { get { return (state.Buttons.B == ButtonState.Pressed); } }

        public static bool XButton { get { return (state.Buttons.X == ButtonState.Pressed); } }

        public static bool YButton { get { return (state.Buttons.Y == ButtonState.Pressed); } }

 

      //Start and Back buttons

        public static bool BackButton { get { return (state.Buttons.Back == ButtonState.Pressed); } }

        public static bool StartButton { get { return (state.Buttons.Start == ButtonState.Pressed); } }

 

      //Thumb sticks

        public static bool LeftThumbButton { get { return (state.Buttons.LeftStick == ButtonState.Pressed); } }

        public static float LeftThumbX { get { return state.ThumbSticks.Left.X; } }

        public static float LeftThumbY { get { return state.ThumbSticks.Left.Y; } }

        public static bool RightThumbButton { get { return (state.Buttons.RightStick == ButtonState.Pressed); } }

        public static float RightThumbX { get { return state.ThumbSticks.Right.X; } }

        public static float RightThumbY { get { return state.ThumbSticks.Right.Y; } }

 

           

      //Shoulder Buttons

        public static bool LeftShoulderButton { get { return (state.Buttons.LeftShoulder == ButtonState.Pressed); } }

        public static bool RightShoulderButton { get { return (state.Buttons.RightShoulder == ButtonState.Pressed); } }

          

        //Triggers

        public static float LeftTrigger { get { return state.Triggers.Left; } }

        public static float RightTrigger { get { return state.Triggers.Right; } }
