fxglgames's Introduction

This repo contains sample games built with FXGL Game Library. Each game focuses on one or two aspects of FXGL, e.g. Drop focuses on bare minimums, Pac-man focuses on AI, etc.

Checkout this commit for Java 8 code for all projects (FXGL 0.5.4). All projects will eventually be upgraded to Java 11 code (FXGL 11.0+).

Run

cd PROJECT_NAME
mvn javafx:run

Build for Mobile

Follow latest instructions from client-samples. A relevant extract is copied below.

For example, to build Breakout for Android (can only build from Linux):

Download GraalVM zip: graalvm-ce-java11-linux-amd64-20.2.0.tar.gz
Set GRAALVM_HOME and JAVA_HOME environment variables to the GraalVM installation directory. For example:

export GRAALVM_HOME=/opt/graalvm-ce-java11-20.2.0
export JAVA_HOME=$GRAALVM_HOME

cd Breakout
mvn clean client:build
mvn client:package

// connect your Android device and allow it installation over USB

mvn client:install

You can now run the game from Android, or you can run with logging from Linux: mvn client:run.

fxglgames's Issues

some suggestions about Bomberman

In the Bomberman part, I think it will be more interesting to generate random walls, so I tried to add the code for randomly modifying 0.txt in BombermanApp.
BombermanApp.md

Add maven defaultGoal to all projects to ease first usage

I just read your JavaMagazin article and wanted to play with some of the examples and checked out the repository.

Personally I'd consider it to be cool if all of the subdirectories would have a defaultGoal set in pom.xml.

Asteroids doesn't seem to run via mvn javafx:run but I had to do a mvn package and start the created JAR with java -jar, while GeometryWars was able to run via javafx:run.

Integrating a defaultGoal is quite easy and would allow anyone to just clone the repo and hit 'mvn' to see the game running.

Thanks for your great work and the cool library!

The cursor image will become a mess?

Hi:

We have successfully run the game
but it seems like there is a problem
when we exit the game
then the cursor image will become a mess
any idea why it happened?
as you can see the messed image is on the screen there

macos 11.2.3 big sur intel cpu

game: space war/ geometry war
I tried openjdk 16 and graal 21.0, both have the same problem

Maybe there isn't any dev repository for fxgl version “17+dev-SNAPSHOT”?

I have downloaded the zip file of FXGLGames some days before, but I found that the IDEA seems not able to resolve the maven dependency such as "com.github.almasb:fxgl:jar:17+dev-SNAPSHOT", is there any recommendation that can help me to run the game example successfully？Thanks so much.

KeyRain ClassNotFoundException running with mvn run

running mvn javafx:run results in:

Error: Could not find or load main class com.almasb.fxglgames.keyrain.KeyRainApp
Caused by: java.lang.ClassNotFoundException: com.almasb.fxglgames.keyrain.KeyRainApp
[ERROR] Command execution failed.

Caused by:

but package for KeyRainApp is keyrain

"Code samples" link on this page is broken

Steps to reproduce:

click on the links for "code samples",

expected behavior: link to code samples

Actual behavior: error 404

suggestion: change the link from

https://github.com/AlmasB/FXGL/tree/release/samples

https://github.com/AlmasB/FXGL/tree/release/fxgl-samples

PongGame

I bought your book, "Learn JavaFX and App Development", I had just finished the third chapter and copied the pong game down onto my computer. When I ran it it didn't work. The enemy paddle and the player paddle both spawned at 0, 0. I'm not sure why this happened. I double checked the code and rewrote all of it, same issue.

Breakout fxgl version cannot be resolved

Breakout uses dev-SNAPSHOT:

FXGLGames/Breakout/pom.xml

Line 19 in 750b42c

<fxgl.version>dev-SNAPSHOT</fxgl.version>

but there does not seem to be that version in maven central

Breakout

UI circle needs to bind to new ball each time, currently it's bound to the first spawned ball and does not work after new level
...

Duplicate code in Space Invaders CollisionHandler subclasses

Classes BulletBossHandler and BulletEnemyHandler have duplicate code. It would be good to fix this.

KeyRain - test with JEP330 launch

Hello Almas,
I am just playing with some JavaFX examples using JEP330 launching, as I found for my first experiments, that basically launch(YourAppClass.class, args) works with on-the-fly classloading.

I quickly fetched required modules from maven (ya, manually, very quickly, so game works....) and found that it tries to access EntityType.main(String[]) so I put him here passing of launch and it kinda works, but crashes on mouse input ...

Can you pls quickly think what can be failing and why the Enum main is required for something??

In run.txt there is command to execute the KeyRainApp.jxc file (containing java sources of your app)
There are even 2 log files where it crashed (but I had to put app.main into enum.main !!! why??)

Its just a experiment to allow quick and dirty changes to tiny apps, now also using some referenced/provided modules...

(I am sharing this my BEGINNERS samples approach with gluon too, found it very cool for tiny things - your example was challenging as it required MANY modules and I manually fed here one by one all of them - some kind of dependecy scan and load from maven will be coo )))

But sure - I also CAN use maven finally - its easy and your tiny example is at the edge of usability of JEP330 - that was the goal to try here :-)))

(sorry, gmail complains about security so I replaced modules only by list of them)

UPDATE: Well, it in fact works :))) but the Enum.main is something I couldnt understand, really

Thanks,
Petr

GeometryWars fails to load bgm.mp3: "jfxmedia.MediaException: Could not create player"

I spotted http://almasb.github.io/FXGLGames/ on reddit, and tried out the first example listed: GeometryWars.
I cloned FXGLGames, changed directory to GeometryWars, executed mvn package which succeeded, and ran the jar with java -jar and it failed.
See log output, etc: http://hastebin.com/fuvuholatu.sm

Geometry Wars TODO List

Weapon types should not be selectable but should be automatically improved as the multiplier grows
Multiplier only grows when collecting crystals (by 1)
Multiplier "checkpoints" at 25 (add extra bullet), 50 (add extra bullet), 100 (add ricochet), 200 (add recharging shockwave)

enable ZGC by default?

Hi:

Openjdk 16 is released
and it supports ZGC which could make gc pause lower than 1ms
so is it possible to enable ZGC by default?

<options>
  <option>-XX:+UseZGC</option>
</optoins>

thx

Old version of FXGL couldn't run on new MacOSX

Hi:

Apple is deprecating OpenGL pipeline on MacOSX
so the demo projects have to upgrade its FXGL version which could provide new pipeline support(Metal instead of OpenGL)
the version should be from 11 -> 17.x(17.3 is recommended)
11 is not longer supported on new MacOSX versions
If we run the application by using FXGL 11 on MacOSX 13.4.1 it will throw exceptions indicating that:
Graphics Device initialization failed for : es2, sw
Error initializing QuantumRenderer: no suitable pipeline found

Create a Website for this Repo

Hi there.

Is there a website for this repo?

Because if you don't have, well, this repo can simply be turned into a website right away. Others will discover this project in that website.

Steps:

Go to Settings and look for GitHub Pages, scroll down. That's almost at the bottom.
You will see there: Branch:none, so you should change that to master because you have a README.md file in the master repo. This will be your page. Click Save first.
Then click Theme, you select a predefined theme of your site.
Visit your site now! The URL will be https://AlmasB.github.io/FXGLGames.

If you were amazed by that, simply read the documentation about GitHub Pages.

Tower Defense towerbase

Hi Almas,

How are you initializing the towerbases in tower defense?

I was making my own version of zombs.io and was wondering how to set the onClick for an object made in the tmx?
