  2d game in java-Monster-Java 2D Game Graphics and Animation
Mon Feb 11, 2008 7:44 pm 

* Project Name:   Java 2d Game - Monster 2d
* Programmer:   msi_333
* Type:   Game 2D/Desktop
* Technology:  Java
* IDE:   NetBeans
* Description:   Base on 2d platform engine to create a 2d game. This is the Monster2d game that i made . It is a net beans Project so if u don't have it you will find all the codes in folder "src". There is also an executable called monster.jar in the folder "dist" which u can run the game without compiling. To run the game you must have JVM(Java Virtual Machine).

1. download Monster_1.rar
2. Unrar it.
3. run the game
have fun, you can make your changes in the code to fix bugs and add new features.
You Can learn many things form this code including :


2D Graphics and Animation with Java
Full-Screen Graphics with Java
Creating a 2D Platform Game
Images with Java
Keyboard Input
Sound Basics using Java Sound API
