LITIENGINE Release notes

0.6.0 - "Trick or Treat!"

LITIENGINE 0.6.0 banner

Surprise! After a quiet period of not releasing a new engine version since January 2022, we proudly present LITIENGINE 0.6.0. This is a release packed mostly with invisible infrastructure changes and refactorings, but also enhanced documentation, tests, and important bugfixes.

There had been some crucial problems in our build and deploy toolchain, which prevented us from releasing new versions for quite a while, but these problems have been resolved and now we are even releasing nightly snapshot builds for you to test out the latest changes!

You may have noticed the versioning of LITIENGINE has changed too. Instead of e.g. v0.5.2-beta, we are now using plain semantic versions for stable releases (starting with this release 0.6.0) and a modified git describe variant (e.g. 0.5.2-166-gb2e597fe-SNAPSHOT/) for snapshot versions.

Since the last release, we have updated to a more recent Java version several times, and recently we have finally moved to the new LTS version Java 21. That means you can now use all the new cutting-edge Java features in your LITIENGINE games!

Of course, we want to thank all our contributors, sponsors, users, and community members for keeping LITIENGINE alive even when we maintainers get lazy. You are the heart of this project!

Here's a quick overview of the changes in this release:

Build Infrastructure:

  • Updated project to Java 21
  • Restored releasability through GitHub actions
  • Introduced nightly snapshot builds
  • Switched versioning to Semantic Versions (assisted bySemVerGuru Gradle plugin.)
  • Cleaned up Gradle dependency management and updateddependencies
  • Rename master branch to main.
  • Restored SonarQube analysis
  • Cleaned up and refactored Gradle project structure

Improvements:

  • Implemented multi-target ForceEffects.
  • Implemented StateEvents to register actions when a State isentered/exited.
  • Implemented 9-sliced image scaling.
  • Added 9-slice scaling option for ImageComponent backgrounds.
  • Added shortcut methods to determine a GuiComponent's centerpoint.
  • Added color interpolation helper.
  • Turned AntiAliasing on for rendering object boxes in utiLITI
  • Added image scaling overloads for bilinear and bicubicinterpolation.
  • Separated emitter saving in utiLITI from blueprint definition.

Bugfixes:

  • Fixed EntityEmitter location jittering.
  • Fixed Particle opacity calculation.
  • Fixed SoundPlaybacks. (contributed by @Gamebuster19901)
  • Fixed Ability impact area calculation.
  • Fixed particle spritesheet assignment dropdown in utiLITI.

  • Fixed duplicate attribute modification in GuiComponentlocation setters. (contributed by @ecchilds)

API changes:

  • Renamed Effect.canAttackEntity to canAffectEntity.

Removals / Deprecations:

  • Removed CompressionUtilities (and tests). There were vulnerabilities in our implementation and the utilities have never actually been used. End users will have a much better experience using libraries such as zip4j.

Documentation and Miscellaneous:

  • Updated license.
  • Updated contribution guide.
  • Added star history to readme.
  • Removed individual developers' funding links.
  • Added .cff citation file.
  • Improved JavaDocs
  • Added more projects to LITIENGINE showcase

v0.5.2-beta - "Java 17 Migration"

LITIENGINE v0.5.1-beta featureimage

Just in time for making your new year's resolution of creating amazing games with LITIENGINE, we proudly present our latest update, packed with 250 commits over the last ten months!

Let's talk about the elephant in the room: LITIENGINE is now fully running on Java 17! In the future, we plan to keep the library updated to the latest stable jdk versions for you to utilize all the juicy new features Java has to offer.

To make building ingame UI more pleasant, the Slider, TextFieldComponent, and SpeechBubble components have seen massive updates.

Bugfixes and UX improvements for utiLITI will ensure a more smooth experience when handling the editor.

Apart from that, a lot has changed in our build and deployment pipeline and the repository is now utilizing GitHub actions instead of Travis CI. This goes along with a completely revised directory structure and proper separation of submodules. The way we bundle native libraries has been adapted and the dependency on steamworks4j has been removed. Please also take note of our changed contribution guidelines: it is now required to comply with the Java code style conventions we provide in the repository (see CONTRIBUTING.md).

Finally, a huge THANK YOU is in order: To all our new code contributors, to the community involved in discussing issues, to everyone providing help in our forum and on Discord, and lastly: Thank you to our new Sponsors RajBet, Trust My Paper, CasinoHex Canada, and ej-technologies (in chronological order of sponsorships)!

What are you waiting for? Start the new year the right way: making games with LITIENGINE.

v0.5.1-beta - "No more Netcode"

LITIENGINE v0.5.1-beta featureimage

This release brings tons of bugfixes and quality-of-life improvements. Feature-wise, the highlight of this version is the addition of a Tweening framework that lets you interpolate values over time, e.g. to let your GuiComponents bounce or your Entities wiggle. As the engine's networking code had been an unmaintained, untested, and even unsafe mess, we have decided to remove the networking package entirely.

Our Discord server has seen some upgrades and we gladly welcome our first community moderator, Conifer! In order to give back some of your love, we have introduced some special roles for our forum and the Discord server:

  • @Supporter : Members that have supported us with donations.
  • @Contributor : Members that have contributed to our open source code repositories
  • @Early Bird : Members that have been part of our community since the Alpha days of LITIENGINE.

We try to assign these roles to the best of our knowledge, but if we forgot you - please don't hesitate to complain. 🙂

Apart from that, we've updated the sponsoring tiers in the LITIENGINE Open Collective, allowing you to support our work financially and with full transparency. We have also started a spreadshirt shop where you can buy all kinds of LITIENGINE related swag and promote the cause (feel free to suggest additional motives)!

As always, huge thanks to all contributors and fans! This is an exciting journey for us and we are grateful to share it with you.

v0.5.0-beta - "Farewell, Alpha!"

LITIENGINE v0.5.0-beta featureimage

This release marks the beginning of a new era for the LITIENGINE. We consider most of the API to be stable and we pretty much settled on the current API design. With the release of our new Website, the documentation and other information about the engine are easier to use and everything can be found in one place.

It's been a long journey but, finally, we're leaving the Alpha status and are looking forward to even more fruitful experiences with the LITIENGINE in the future. A big thank you to all members of this community. Without your feedback and contributions we wouldn't be here today. You're awesome!
