Compile and run the program

Create a batch file

Use your text editor to create a text file named CompileAndRun.bat and store it in the folder named Slick0100a .

(Once again, be careful to ensure that the file has the correct extension, particularly if you create it with Windows Notepad. An extension of .txt won'twork.)

Carefully copy the contents Listing 2 into the text file. This is the file that you will use in your attempt to compile and run yoursource-code file named Slick0100a.java . (Line breaks or wrapped lines are not allowed. Make certain that your batch file has only sevenlines of text exclusive of blank lines.)

Listing 2 . The file named CompileAndRun.bat.
echo off del *.classrem refer to jar files in the folder named jars javac -cp .;../jars/slick.jar;../jars/lwjgl.jar Slick0100a.javarem set the java.library.path and the classpath and run the program java -Djava.library.path=../lwjglbin -cp .;../jars/slick.jar;../jars/lwjgl.jar Slick0100apause

Execute the batch file

Double-click your new batch file named CompileAndRun.bat (or execute it in whatever manner you prefer.) This should cause two new windows to appear on your screen.

Slick2D output during startup

The first window to appear should look similar to Figure 1 .

Figure 1 . Output from Slick2D during program startup.
Missing image.

Figure 1 shows information produced by Slick2D when a compiled Slick2D program starts running.

A default Slick2D game window

The second window to appear should look something like Figure 2 .

Figure 2 . A default Slick2D game window.
Missing image.

Figure 2 is a default Slick2D game window. As you will learn in the next module, this particularSlick2D program has no interesting behavior. In effect, it is an "empty" game program. Therefore, the only thingshowing in the game window is a counter in the top left corner that shows the execution rate in frames per second.

Run the program

I encourage you to copy the code from Listing 1 and Listing 2 . Install the necessary software on your computer as described above. Compile the code and executeit. If you don't see results similar to those shown above, go back and review the instructions very carefully.

Summary

I showed you how to install Slick2D in such a way that you can easily compile and execute Slick2D programs from the command line with no need for a high levelIDE.

What's next?

In the next module, I will use the code from Listing 1 to begin explaining the anatomy of a basic Slick2D game engine.
