Tick Tick - Building JavaScript Games for Phones, Tablets, and Desktop - page 308

This platform game includes a number of basic elements that are found in many other games
as well:

 It should be possible to play different levels.

 These levels should be loaded from a separate file so they can be changed

without having to know how the game code works.

 The game should support animated characters for both the player and the

enemies.

 The player should control the actions of a player character that can run or jump.

 There should be some basic physics in the game to manage falling, colliding

with objects, jumping on platforms, and so on.

That is quite a list! Fortunately, you can reuse many of the classes you've already developed.
The following chapters look at all the items on the list. If you want to play the complete version
of the Tick Tick game, get the sample code for Chapter 29 and open the TickTick.html file in the
TickTickFinal folder.
