Gaming Mechanics:Gaming Mechanics:

In update method of GameScreen, we allow ball to move. In present method of GameScreen, we just draw the ball.

If Ball touches the bar, vY = - vYand vX = (bar.X-ball.X)* (some factor)

If Ball touches the borders, vX or vY changes sign.

(The hard part is to tell when does the ball touch the bar)

Otherwise, the ball moves:

X= X+vX*deltaTime Y= Y+vY*deltaTime vY= vY+a*deltaTime

deltaTime is the time taken between two successive GameScreen updates.

Also, we have Coin object for coin. We change coin’s position in update method and draw it in present method of GameScreen object.

There is also the catching of the coin.

If you are bad at graphics, get someone else to work with you.

Maybe using a gaming engine is better.

Don’t try to finish as fast as you can. There is no race!!!
