Hello friends,
Welcome you all in the Android Game
Development [Part6].
In the part5 we
were setting up the Game Architecture. We have created the interfaces and we
have also created the implementation classes that use those interfaces.
In this part6, we
will continue our Game Architecture setup.
Setting up the Game
Architecture:-
In the previous
part we have completed till step 9. We will continue from there.
10)
Copy and
paste the following images into the assets folder.
· dead.png
· base_brick.png
· common_brick.png
· hidden_brick.png
· final_brick.png
· small_image1.png
· small_normal.png
· small_down.png
· small_up.png
· game_background.png
· game_background2.png
· menu.png
· button.jpg
· splash.jpg
· menutheme.mp3
Copy any mp3 file into assets folder and rename it to menutheme.mp3
11) Copy the icon.png image file into res à drawable-hdpi folder
Our game architecture setup has been done now. Next step is to the add the gamecode.
Merging the GameCode :-
Now we are at the step of merging the final game code what we have developed for the java application.
1)
Create a
new package.
Right click on the src directory à New à package.
Name it as com.pocogame.gamecode
2)
Create the
following classes
a. Assets.java
b. Background.java
c. Bricks.java
d. HandlingXY.java
e. GameScreen.java
f. LoadingScreen.java
g. MainMenuScreen.java
h. SampleGame.java
i.
SplashLoadingScreen.java
3)
Copy and
paste the following code into the respective file.

Assets class – In this class we are creating reference
variables to all assets (images/audio) that will be used in our game.
SplashLoadingScreen & LoadingScreen – SplashLoadingScreen class will be used to load the splash screen. Loading Screen class will be used to load the menu screen.
SplashLoadingScreen & LoadingScreen – SplashLoadingScreen class will be used to load the splash screen. Loading Screen class will be used to load the menu screen.
Main Menu Screen - Used to start the game.
GameScreen - All the gameplay will take place in this class. This class is similar to our GameMain class.
SampleGame - The Activity class that is launched when the game starts. It opens our application.
As you know activity class is like a class which have the main() func. Here in the AndroidManifest.xml file we are giving the activity class name.
So the SampleGame.java class got called first. getInitScreen() when it calls first time, we load all the assets and create a object of SplashLoadingScreen.
5) Run the application and test it on the Emulator. You can port this application on your android device also.
You can check the Android Game Development Tutorial [ Part 3 ] to know more how to run the android application on Emulator or an Android Device.
Enjoy the game buddies.
Please give your suggestions and share it with your buddies.
