jStella applet difficulties...

Dragnerok X · September 22, 2007

Recently, I've been trying to integrate jStella into my Geocities website in order to play a few of the homebrew games I offer there. I'm able to get the java window up and visible, but the problem is, I get a red "x" on the upper left hand corner of the java window and this error message when trying to run it:

JStella - detected cartridge type: F6
JStella display: YStart=37, DisplayHeight=196

...and if this means anything, here's the code I've placed in for jStella.

<applet archive="jstella.jar" code="jstella.runner.JStellaApplet.class" height="436" width="640"> 
<PARAM NAME=ROM  VALUE="Combat_DX_-_Demo_6.bin">
Your browser doesn't seem to support applets.
</applet>

Any help would be appreciated.

Sorry for the dumb question, but you do have the "jstella.jar" in the same directory, right? And it's actually called "jstealla.jar?"

Yes, I just named the .75 release jstella.jar for convenience sake.

If anything, here's a link to the page where I'm working on it. Perhaps someone else may have better luck.

Must be a browser problem or old version of Java on your end, since the game comes up just fine on my computer when I click the link.

Good to hear. :thumbsup:

I'll finish this as soon as I can (it will probably be up tomorrow), and will take a look at my computer... :ponder:

EDIT: Just discovered what it was, the applet doesn't load properly when I access it from the "preview" mode of my webpage. Almost done setting it up, though.

Yes, it works for me too, at least the whole combat motif comes up...I don't know what stage of development the ROM is, but it wasn't able to move the tanks...

It's almost done, actually. SeaGtGruff and I just need to add AI and Sound. The red tank moves, if you press F5 as I documented with "press F5 to activate manual tank control", in that once AI is added it would technically be "manual" tank control. Maybe I need to re-word that. :ponder:

Oh, BTW, Is there a way allow 2-player support over the applet?

Sorry, it works fine. I didn't read carefully.

There will be support for 2 (local) players...it's actually almost there now, but there just isn't a convenient way to establish control config via Applet parameters. Assuming we are discussing 2 LOCAL players (using the same keyboard), what does everyone think the default keyboard arrangement should be for both player 1 and player 2?

Yes, that's what I was referring to.

My suggestion is....

Player 1: Arrow keys, space bar.

Player 2: (W, S, A, D), left control

I've added some default keys for player B...since this is technically version 0.81, it isn't yet available as a JAR, but it is available in source code form on the CVS.

Both space bar and enter will work as Player A buttons.

Player B buttons are WSAD and Control to fire. Also, Y will fire as well.

Good to know. :thumbsup:

I'll gladly update whenever you have the .jar ready.

I went ahead and built 0.81. You can download it from the following link:

jstella_0_81.jar

Got it. It took me about an hour to re-document the controls but I'd say the feature was well worth it.

Edit: I hate to give you more features to add; but is there any way someone could "preset" a difficulty switch

setting for a particular game? I say this because with the way my (not yet existant) AI works, it might confuse people.

Go back to jstella.mauvila.com and get the jstella_0_82.jar file, and also the jstella.cfg file. The cfg file can be edited with a text editor (should be self-explanatory), and should be placed in the same directory as your jar and ROM.

In your HTML applet tag, add the following parameter :

This is new as of 10 minutes ago (version 0.82).

Thanks for the update.

Combat DX Online is updated and couldn't be much better.

cool - is there a configfile setting for stereo? I tried parsing the source in CVS, but couldn't tell.

Not yet, but it may be possible to do right now using JavaScript...

If you build from the most recent code (JStella 0.83) via the CVS, you can use the following config item:

jstella.stereomode=true

Also, I made a getIntercessor() method, which should open up a whole lot to JavaScript.

(There is now also a direct setStereoSound(boolean aEnabled) method that can be called directly on the applet from JavaScript).

Cool - I'll see if I can figure out how to do that this weekend.
