Thank you for taking the time to clean this up and release it. I've never played DD Poker, but have experienced the loss of other games when servers go down and the software stops being updated.

I realize source releases aren't always possible, so it's a great gift to the community when one can make it happen and they put in the effort to do so.

Thanks for the kind words. It did take a bit of work, but it was my pleasure to do so. I hope it is valuable to someone!

This was a bit of a bear to get running on my Mac. Everything depends on ddpoker.rc, which doesn't behave as expected unless an OSNAME environment variable is defined. I don't have that on macOS 14 (Sonoma) Mac using either zsh or bash. I hopped onto a 10.13 (High Sierra) hackintosh, and it doesn't have that variable either.

For the person who was having trouble getting this to work on an M1 Mac (flagged, really?), try this (after installing Java 8 and Maven using Homebrew):

    % git clone https://github.com/dougdonohoe/ddpoker.git
    ...
    % cd ddpoker
    % export OSNAME=darwin
    % source ddpoker.rc
    JAVA_HOME changed, version now openjdk version "1.8.0_422"
    % mvn-package-no-tests
    ...
    % poker

I built this before figuring out the OSNAME thing, so I can't actually vouch for the build step working out of the box.

Anyway, thank you very much, Doug. This looks really cool.

I'll have to fix the OSNAME thing, my apologies. That's an env var I have in my local ".zshrc" I had overlooked. I'll fix it later today.

This is fixed. Proper variable is `OSTYPE`, which I've fixed. `OSNAME` is a personal historical artifact.

fast fix! appreciate this

I added a `TL;DR` section to the base readme with jus this info.

Thank you for taking the time to open source this! It’s fun peeking at the source code of old games from bygone eras and more open source games are definitely a good thing.

My pleasure. Thanks for taking a peek.

Wow thanks a lot! We played DD Poker during the Pandemic. It really saved us from going insane:)

That's great! You are the 2nd person who's told me that. You don't happen to know someone named Ryan in Oakland?

No, I am from germany. Also good job on programming a game that plays flawlessly on pretty much all systems after so much time. Also, online play via IP address was super easy.

Any plans to release the source for War Age of Imperialism?

I bought and played the heck out of that game years ago but never could get anyone to try it multiplayer.

Thanks for the great games!

Glad you enjoyed the games! Unfortunately, I don't own the IP rights to War! Age of Imperialism, so can't release the source code.

I wonder if this could be made to work in the browser using CheerpJ?

Interesting. I hadn't heard of this before. I'll have to check it out.

Lead dev of CheerpJ here, if you need support you can find us on Discord: https://discord.gg/X9ruPkchM5

Edit: Tool a quick look at the repo, if the game is a Java 8 Swing application (as it seems) then it will most likely work out-of-the-box with CheerpJ

Ported my java game to Cheerp and it was the easiest thing ever. I highly recommend and you can see the results here: http://liarsdiceonline.com

Only criticism is that it can take a few MINUTES to initially load the game and there isn't a loading bar or anything

I see the game was ported with the legacy CheerpJ 2.3 runtime. Consider upgrading to the new CheerpJ 3.0. Improving boot times has been one of our main goals and upgrading is very easy: https://cheerpj.com/docs/migrating-from-cheerpj2

Fun game! I thought you programmed it wrong till I realized in your version of liars dice 1s are wild. Also never played the way of guessing the total number of dots, and we always have loser go first on the next round. Thanks for sharing!

In our game, one's are wild unless ones are specifically called. Yes, the loser should go next.

ah, good old Java Swing. Spent years working on big Swing projects.

BTW, you want to wrap statements like this in a logger.isDebugEnabled() especially in the paint loop because otherwise you always incur the cost of string concat, debug or not!

> logger.debug("REPAINT COMPONENT "+(CNT++)+" ("+ImageComponent.getDebugColorName()+") portion " + bounds_.x +","+bounds_.y+" " +bounds_.width+"x"+bounds_.height);

That code block is in an "if (debug)" block, which is enabled if "settings.debug=true" is set.

“Even though DD Poker and the backend servers was shutdown in July 2017, folks continue to play it by manually sharing game URLs”

Anyone have more details about how the above works?

The in-game help explains, which I have a copy here:

https://static.ddpoker.com/gamehelp/help/hostonline.html

I just added functionality to allow users to specify a DD Poker backend server in the UI (see https://github.com/dougdonohoe/ddpoker/issues/1). This makes it easier for users to connect to a private DD Poker server in their community.

I've never worked with Java before.

Out of curiosity, do you think the game's architecture and tech stack would be easily portable to a more modern setup, or would it require a significant rewrite?

The architecture is very Java centric. The UI is all Swing based (no 3D graphics engine stuff). I would think very little is portable to a modern gaming engine.

Java 22 was released less than a month ago.

Thanks!

(My son loves to play.)

BTW, the old Windows installer runs great under Crossover on Apple Silicon.

I'm going to try running this native. I'll file issues for what I can't readily fix.

Awesome, glad to hear your son likes it. Thanks for your help.

Could you say a bit about how the poker AI works? I know it's not modern, but just curious. Thanks.

The source code is right there, you can dive in. [0]

I just took a very quick scan read, and think by modern standards calling it "AI" would be a stretch ;)

[0] https://github.com/dougdonohoe/ddpoker/tree/main/code/poker/... - I recommend looking at V1Player.java and V2Player.java in particular

There is a write up in the docs/AI_Whitepaper.rtf file.
