Java games rock!


« Posted 2005-03-02 06:41:35 »

Hi.

I am running the simplest of test programs trying to find any type of device connected to the default environment.

I believe I am properly running the program with proper linking to the jar's.
I have a folder 'controller' in the same path as my user.dir, which was a step in itself.

regardless, this is my command line run:

java -cp .:/Library/Java/Extensions/controller/jinput.jar:/Library/Java/Extensions/controller/jutils.jar:/Library/Java/Extensions/controller/controller.jar  GUI.JoystickInput

and here is the output:

I have been working on this problem for a while, and my senior project is basically at a standstill until I get through this.

If anyone could please help me out, it would be the most incredibly  appreciated

Ok.

So this problem has now been found.

I had for some reason put the jutil and jinput jars in the /Library/Java/Extension/ and they were being loaded twice causing havoc.

My "last" problem now is being able to actually see any inputs.

My ControllerEnvironment.getDefaultEnvironment() still returns an empty array.

Any word?

thanks alot, Jason
