This time lets see how, without any external texture, we will animate forms and use collision detection.
To illustrate this, lets make a Pong game.
We will need to draw 3 rectangles : 2 bars and one ball.
The update method will manage check the keyboard, move the positions of each rectangle and check collision thru the intersect rectangle method.
The code : XNA_DEMO_17
up/down for player2, z/s for player1 : as simple as that.
See below a short video.
