XNA & 360

The bits and bytes of XNA and C# for your 360...

 

 

Gamepad Vibration!!!  Its only one line of code, and it can make your console app/game so much sweeter.  If you bump into a wall you can do a thud on your game pad, or if you want to give the user a kick, you can just give a quick vibration.

 

There is the left and right rotation motors.  If you run the demo below you can use the left and right thumbsticks to contol there speeds.  And you'll feel that the left motor is a heavy deep rumble, while the right motor is a fast whinny one giving you two completly different effects....but also letting you combine them to creat unique ones!

 

The main function is a member of the GamePad class.  Letting you specify which controller (i.e. which player pad) and the motor speeds.

 

GamePad.SetVibration(PlayerIndex.One, leftMotor, rightMotor);

 

Hopfully you'll be creating unique and exciting things with the gamepad vibration ability!
