Getting Started

Ok, in order to get the initial crude version of the game up and running you are going to have to write some code. But before you do that create a directory on your desktop called "si" short for spaceinvaders. Then download these files, storing them in that directory:

• Alien.java
• AlienArmy.java
• AlienShot.java
• Shot.java
• SpaceInvaders.java
• Ship.java

In addition, download these images files for later use (put them in the same directory):

• back3.jpg
• blackhole_small.jpg
• meteorattacks_small.jpg
• solarearth_small.jpg
• solarwormhole_small.jpg
• terraform_small.jpg
• alien.jpg
• alienFull.jpg

Now update them so they match these files:

• Alien.java
• Shot.java
• SpaceInvaders.java
• Ship.java

Once you've done that we can try and run the initial game. To do this we must first convert the code we've written into a format the computer can understand (in Java this is bytecode). To do this open up a cmd prompt (click on start, then run and type cmd and finally click ok). Then type: "cd Desktop\si". If there any problems with this just grab the nearest lab tutor and they will help you.

To compile your code type:

javac *.java

If you don't encounter any errors then you can run your game with this command:

java -cp . SpaceInvaders

As before, if you get any errors just ask your lab tutor.

Assuming that is complete and you are familiar with playing the game then you can head back and start to improve it. <here>
