A small Chrome-Dino-like game i did during my first year at the University.

Jumping Game in Java

A game i did during my first year at the University

About

The game was created back in 2017 and was developed in Eclipse Oxygen. I thought it would be of more use in my University era projects here on GitHub than collecting bit-dust on some harddrive of mine.

Java version

The Java version i used to compile this game was.

$ javac -version
javac 9.0.4

$ java -version
java 9.0.4

Compiling

Both of the commands must be run from the src directory.

Compile the game.

$ javac -d ../bin ./game/Jumper.java

Copy the images directory to the bin directory.

$ cp ./images/ ../bin/ -r

Running

Run the program. Must be ran from the bin directory.

$ java ./game/Jumper

Note that you can't append .class to the Jumper-file when executing the game.

Author notes

One of the things i wanted to try out with this little game was to have the game be rendered using a sprite-array. The array is shifted in different speeds giving the illusion of horizontal movement.

public void initMap() {    
     map = new char[mapHeight][mapWidth];

     map[0] = "----------------------------------------------------------------".toCharArray();
     map[1] = "----------------------------------------%!@@@-------------------".toCharArray();
     map[2] = "--------------------------------------%@@!!!@@------------------".toCharArray();
     map[3] = "------------------------------------%%%@@!!!%%@@----------------".toCharArray();
     map[4] = "-------------------!@-------------------------------------------".toCharArray();
     map[5] = "------------------%%@@---------------------------!!-------------".toCharArray();
     map[6] = "-----------------%!!@@@@-----------------------!!@@!------------".toCharArray();
     map[7] = "--------------@@!!%%@@@!!@@------------------%%%@!!!@@@!--------".toCharArray();
     map[8] = "-------------------------------------------@@%%!!@@!%%@@@-------".toCharArray();
     map[9] = "-----------------------------------------%%!!@@@@@@!!@@@@@------".toCharArray();
    map[10] = "----------!@----------------------------------------------------".toCharArray();
