FXGL VS Litiengine

I downloaded javafx from here: https://github.com/AlmasB/FXGL as a zip, extracted it, then went to my project structure and added it to my libraries. For a couple seconds it seems to work, but then I get the error again, and the folder isn't showing up in my external libraries.

Java seems to have gained a second wind in recent years, and the innovation in this ecosystem is speeding up. Java 20 and LTS release 21 are expected to happen this year. RIFE2, an actively-developed pure-Java web framework, has recently caught my attention. Like Javalin, it appears to be built on top of the successful Jetty server. I also started exploring FXGL for building games with Java. Lastly, as concerns over COVID-19 variants wane I expect an increase in Java developers participating in community events. For example, Chicago finally had its first in-person JConf event and the Chicago Java User Group (CJUG) is easing back into in-person events.

Have you checked FXGL? It’s built on top of JavaFX.

You might get some good use out of FXGL, a Java / JavaFX / Kotlin Game Library. It would probably save you implementing some things from scratch. It might not cover everything that you need, but it probably be at least somewhat helpful.

If you don't mind depending on all of JavaFX you could also try: https://github.com/AlmasB/FXGL Haven't tried it myself but seems like an easy way to start making a game. The author is a university lecturer, so there are plenty of tutorials for games. As the other comment said, Compose Desktop would be a nice choice for a chess game, with the added benefit of easy porting to Android in case you're interested in learning it!

I can highly recommend FXGL https://github.com/AlmasB/FXGL to get started building simpler 2d games before looking into 3d engines which can be daunting unless that’s what you are in for. Nice and easy api’s with everything you need as well as lots of example games to learn from.

Sure. See FXGL

Either libGDX (https://libgdx.com) or FXGL (http://almasb.github.io/FXGL/) . libGDX is more complicated and more powerful, FGXL is better suited for simpler games and so easier for beginners, but recently it's development is quite active and more and more features are available.

Have you looked at https://litiengine.com/ code? Its an interesting little pure java AWT based engine. You could see how they are doing their game loop.

Tired of all the vaguely ambiguous harvesting references? Just want to take your mind off of all the comfy farming games? How about some old-school shooty fun in space? Star ReaperZ is an arcade space shoot-‘em-up made with our very own open source Java 2D game engine LITIENGINE. We didn’t have the full weekend at our disposal, so we had to cut some corners with graphics and audio, but all in all, you will have a great time harvesting innocent galaxies! Check out the game HERE!. Oh, and of course the game is open source!

From a quick search this is the main java engine i found: Litirngine

For native binaries, we now have https://www.graalvm.org/reference-manual/native-image/, but it probably doesn't yet work nicely with game frameworks? Not sure.

There are some engines, frameworks: https://jmonkeyengine.org/, https://litiengine.com/, https://libgdx.com/, https://www.lwjgl.org/.

But I have no real experience with any of those.

so I am trying Litiengine (https://litiengine.com/), but the problem is, I am getting this error everytime I wanna build project... I tried everything what I found on the internet, but it didn't help so far... New project has the same issue, when I changed sdk (15), the error was the same, just not 11, but 15...

Google is your friend. Search terms "Java 2d game engine": https://litiengine.com/

LibGDX is often recommended, but I'm also aware of FXGL and LITIENGINE.
