Chapter 7. Working with Update Handlers

Update handlers give us a way to run specific portions of code every time that the engine updates. Some game engines have one built in as a main loop, but with AndEngine we can create as many of these loops as necessary with ease. This chapter will cover the following recipes:

• Getting started with update handlers

• Attaching an update handler to an entity

• Using update handlers with conditionals

• Handling the removal of an entity from the game

• Adding game timers

• Setting entity properties based on the time passed
