Flappy bird (2)

After flappy bird scratch at previous post, we will add more two bars to increase the difficulty.

Declare one more variable name xbar34

Initial two new bars.

bar3 = BitmapFactory.decodeResource(getResources(), R.drawable.kb);

bar4 = BitmapFactory.decodeResource(getResources(), R.drawable.kb);

Set their position next to old bars 200dp.

xbar34 = r+200;

We draw them near top edge to make them not straight with first gap.

canvas.drawBitmap(bar3, xbar34, -40, null);

canvas.drawBitmap(bar4, xbar34, 320, null);

Make rect touch to get hit.

Rect touch3 = new Rect(xbar34, 0, xbar34 + bar.getWidth(),

                          bar.getHeight()-40);

Rect touch4 = new Rect(xbar34, 320, xbar34 + bar.getWidth(),

                          320 + bar.getHeight());

Make the new bars run.

xbar34 = xbar34 - 7;

Make them return when go to left edge.

if (xbar34 < -bar.getWidth()) {

     xbar34 = r;                   

}

In case MotionEvent.ACTION_DOWN: set position xthanh34 when game start

xbar34 = r+200;

Run to make sure we have two more bars run.

Add these lines to get hit of bird and new bars.

if (Rect.intersects(touch, touch3)) {

hit = true;

soundPool.play(bump, 0.9f, 0.1f, 1, 0, 0.7f);

}

if (Rect.intersects(touch, touch4)) {

hit = true;

soundPool.play(bump, 0.9f, 0.1f, 1, 0, 0.7f);

}

Declare one more variable xcount2 to count number times bird fly through second gap.

xcount2 = xbar34 - 200 + bar.getWidth() + bird.getWidth();

Add above line in if (xbar34 < -bar.getWidth()) { to make it return and in case MotionEvent.ACTION_DOWN: to start game again.

Add this lien to make it run parellel with bars.

xdem2 = xdem2 - 7;

Add this lines to count number times bird fly through gap  2.

if (xdem2 < 0) {

xdem2 = r;

dem = dem + 1;

}

It’s done now, we have second gap at higher position.

To add three gap, you can do the same.
