Lab 6: Cannon Game App ( Due 01 Mar 2013 )

The purpose of this lab is to design an Android App that will allow the user to play a more challenging game - to destroy a seven piece target within a ten-second time limit. The game has four components - a cannon, a cannonball, a target, and a blocker that defends the target. The user aims the cannon by touching the screen - the cannon aims at the touched point. The cannon then fires a cannonball by double-tapping the screen. At the end of the game, the app displays an AlertDialog indicating whether the user won or lost, the number of shots fired and the elapsed time. With this app you will be learning the following technologies on the Android platform:

• Create a custom SurfaceView subclass and use it to display the game's graphics from a separate thread
• Draw graphics using Paint and Canvas
• Override the Activity's onTouchEvent to process touch events when the user touches the screen or drags a finger on the screen
• Use a GestureDetector to recognize more sophisticated user touch motions such as double taps
• Perform simple collision detection
• Add sound to your app using a SoundPool and the AudioManager
• Override three additional Activity lifecycle methods

Realize that the instructions in the book is for an older version of eclipse and android api. One of the challenges that you will have to face is to map the older features mentioned in the instructions to the newer features of both eclipse and the android platform.

After you finish, please demonstrate to Tong Zhao what you have achieved. You will then write a report that will have the following format

We will give you 1 class day grace period for showing the execution of your program to Tong Zhao. After the grace period there will be a late penalty of 10% for the next class period that you show the execution of your lab to Tong Zhao. After that we will not accept your lab.
