simplegameclass's Introduction

README

A simple Game class project will all inside to provide basics for 2D game framreowkr based on the JDK 19 only.

One master class with subclasses to define principle and reduce footprint.
No specific java build tool like maven or gradle, but only bash scripts with java/javac JDK commands. any specific dependencies may be store in the lib directory for build or test usage.

build

build.sh

run

java -jar target/simpleclass.jar

Available CLI arguments & configuration file parameters:

Configuration	Argument	Type	Description
game.size	size	Dimension	define window dimension: `(width)x(height)`
game.screen.resolution	resolution	Dimension	Define Screen resolution `(width)x(height)`
game.physic.play.area	playarea	Dimension	Define the physic module play area dimension `(width)x(height)`
game.physic.gravity	gravity	Double	Define the physic module gravity value `0.981`
game.title	title	String	define the title for the game window `My Own Title`
game.debug	debug	Integer	set the debug information level `0` to `5` where 0 = no info

Any argument can be activated by using the command line option :

java -jar target/simpleclass.jar game.title=ThisIsMyWindow

NOTE

An internal configuration file config.properties is provided into the JAR itself, but you can overload the properties with t a side part my-config.properties file, located at the root place of the JAR file.
path_to_my_jar
|_ simplegameclass.jar
|_ my-config.properties
Now executing the JAR file, default values will be loaded from internal file, and then every key=value from my-config.properties will overload those default values.

A new window running the demonstration game will appear with "ThisIsMyWindow" as title.
