What's next?

Sounds

Loading sounds into the game is similar to the loading of images, we use the function this.load.audio(key, url) to load sounds into the game. To play a sound we use this.sound.play(key).

I have prepared some sounds for you to use:

Moving clouds in the background

I prepared one other sprite for this exercise:

	name	url
	cloud	https://hubben-amal.github.io/game-io-workshops/img/bouncy-ball/cloud.png

We can use this cloud to make the background a little bit more interesting. Try adding some clouds in the background using the random functions. Then let them move using setPosition or setVelocity. Note that for velocity to work the clouds will need to be physics objects. Think about what happens to clouds who go off screen and the spawning of new clouds. Use a lower speed than the ground to create a parallax effect.

Ramping difficulty

Now that we separated the pillar spawning and have grouped them together we are all set to allow for more pillars to exist at the same time. Think about how to spawn more and more pillars closer together over time.

Rolling ball

An image can be rotated via its methods setAngle(degrees) or setRotation(radians). We can use this to make our ball roll over the ground. If you remember your circle mathematics you should be able to derive the rotation speed from the speed of the ground.

More controls

There is a better way to handle the input of a key if you want to perform a single action when it is pressed:

this.input.keyboard.on('keydown_<key>', callback);
this.input.keyboard.on('keyup_<key>', callback);

Where you replace <key> with the key you want to handle, some examples:

and callback is the name of the function you want to call once the key is down or up.

See an example of what is possible!
