Chapter 3. Moving Sprites Around the Screen – An Endless Runner

A while ago, endless runners started with a game called Helicopter where you had to drive a helicopter through an endless cave, just pressing a button to give it thrust.

Then, games became more complex until mobile gaming started to spread. Endless runners started gaining a new popularity due to their simple one tap control. The player is just required to touch anywhere when needed to control a helicopter.

In this chapter, you are going to build an endless runner that features a spaceship flying through a city while avoiding dangerous asteroids.

In the making of this game, you will learn, among other things, how to:

• Scroll big images to give an idea on an endless background
• Schedule events
• Control a frame rate
• Check collision between sprites
• Create a simple particle system
• Move sprites manually or using actions

Moreover, although this is supposed to be a cross-platform game, you will also learn about mouse-only controls...
