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 tireless 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.

LITIENGINE is available through Maven Central:

implementation 'de.gurkenlabs:litiengine:0.5.2'

implementation("de.gurkenlabs:litiengine:0.5.2")

<dependency>
  <groupId>de.gurkenlabs</groupId>
  <artifactId>litiengine</artifactId>
  <version>0.5.2</version>
</dependency>

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.

Finally!

As of today, we end the four year-long LITIENGINE alpha, spanning a total of 17 feature-packed releases. Simultaneously, LITIENGINE hits its first beta release v0.5.0-beta, marking a magnificent milestone for us.

What once started as an overly ambitious hobby project of two naive brothers seeking to create their own video game, is now one of the most successful Java 2D game engines on the market - despite being in early access! Our hearts are filled with joy seeing how popular LITIENGINE has become and we want to thank you from the bottom of our heart.

To celebrate the prosperity of LITIENGINE and as a big thank you to our supporters, we have completely remade the LITIENGINE website from scratch. It is now a well-designed, streamlined experience that guides users to the most important points of interest more naturally. With everything designed to be maximally self-contained, we are also no longer hosting the documentation, JavaDocs, and Download page externally: The LITIENGINE website thus has become a purposeful and holistic hub for everything related to our favourite software.

We are convinced that LITIENGINE's user base and relevance will keep growing and there are some thrilling years ahead of us. If you're not already part of the LITIENGINE family, join our lovely community and explore the exciting features of our new website and LITIENGINE's first beta release.

Features / Improvements

• 91a81fbcc48523c4d8a6327ac16fae37e98ee295 Improved the delay() of the loop tick by accounting for the delay error that is inevitably caused by the fact that Thread.sleep uses long instead of double values
• 012b75d4488d5b00dc4b6321b3246e54c0f87aa2 Minor version numbers of Tiled map format releases are no longer considered when checking for version support because they are only used for bugfix releases and have no effect on the .tmx format.
• b1ca5de3a12430978ee33127beed4eddb945a4d1 Implemented possibility to retrieve a layer by name and ID
• c7af38a475b0c185a0786abd6d6026bd9084f715 Added methods for text and shape rendering with antialiasing

Changes

#243 TMX Overhaul, Part 2

• All resources except spritesheets are now cached using URLs as keys (they still work with strings)
• Resources can now be loaded asynchronously
• Most entities loaded from map objects are now rendered as part of their respective layers
• Tilesets that use individual images for each tile are now supported
• Tile types are now supported
• File custom properties are now supported, though only tentatively
• Light sources now use an enum for their type
• Various refinements for several features

Other changes

• 4fe0e8130bad562e81bf713ebee5d35e8f4007a1 Rename collisionboxHeightFactor and collisionboxWidthFactor MapObjectProperties to collisionboxHeight and collisionboxWidth. This might require you to adjust maps created with previous versions of the engine.

  • 91a81fbcc48523c4d8a6327ac16fae37e98ee295 The input loop is no longer a GameLoop and instead "just" a plain UpdateLoop. -> There should only be one GameLoop (that provides enhanced functionality like TimedActions)
• 4a37838d4391edc7b6a54ad0e55476c18cd52794 Renamed the Map class to TmxMap to avoid collisions with java.util.Map

Features / Improvements

• Squeezed out a few more frames by improving the caching mechanisms for sprites.
• Removed the parallel MapLayer rendering because it produced more overhead than it saved rendering time.
• Affected entities of Abilities are now always sorted independent of whether multi-target is enabled.
• Tiles now only evaluate their flipped state once when the constructor is called.
• Slightly improved the performance of the RenderComponent.
• Improved the performance of the UpdateLoop and RenderLoop
  • The UpdateLoop is no longer using a stream to iterate all updatables.

• Extended the IMobileEntity implementation to calculate the velocity for the current tick.
• Implemented TimeUtilities.nanoToMs method to convert nano seconds to ms.
• Implemented Gamepad.onReleased event.
• Make use of Gamepad default deadzones in the GamepadEntityController.
• Extended the Environment with the possiblity to retrieve an IEntity of a particular type by its id/name .
• Implemented the possibility to check whether a resource string is present.
• Implemented the possibility to check whether a speechbubble is currently active for an entity.
• Implemented methods on the RenderEngine that allow to scale an image via AffineTransform.
• Extended the IAnimationController with the possibility to provide an AffineTransform.
• Implemented the possibility to override MapObject loading functionality
  • Previously, a lot of logic was implemented internally within the MapObjectLoaders, so child implementations would have to re-implement some basic stuff on their own. With this change, every MapObjectLoader has a createXXX method that can be simply overwritten in case one just wants to adjust the created instance of provide a custom child implementation.
• Implement the possibility to scale Props to the size of the IEntity.
• Extended the ICombatEntity with a method that allows to check whether it was hit in a specified time span.
• Add new Valign and Align values.
• #74 Implemented the possibility to set the origin Align and Valign for Emitters.
• Implemented the possibility to provide the CollisionType for raycasts.
• Clean up Animation implementation to no longer use a Spritesheet that was being unloaded (either removed or updated).
  • Previously the Animation class would still have a reference to the old deprecated Spritesheet.
  • Spritesheets now have a isLoaded() flag that indicates whether they are (still) loaded in the current game instance.
• Implemented a method that allows to check whether a specific image extension is supported by the engine. (ImageFormat.isSupported).
• #75 Implemented the possibility to control whether particles fade.
  • Previously this was active for normal particles and it wasn't possible to disable the behavior. With this change, it is possible to define whether particles should fade out over the course of their TTL. This also works for sprite particles now.
• Improved the Particle implementation by some collision related options.
  • With this change the particles can support continuousCollision if required. Note that this is very performance crucial and should be only used when absolutely necessary.
• Extended SoundPlayback with method to check whether it is currently playing.
• Improved performance for raycast collision checks.
• #113 Implemented possibility to set a custom gain for a SoundPlayback.
• The SoundEngine is now using the Input.getLoop() to update the sounds.
  • This was necessary to support adjusting sounds while the main GameLoop is paused.
• Extended the IEnvironment with the possibility to search IEntiteis by multiple Tags.
• Extended the IScreenManager with the possibility to get its center point.
• Extended IMouse with method to set location by two double values.

• Expose the setBackground(Color) method for the RenderComponent.
• Custom MapObject properties are now serialized in alphabetical order.
• The order of a Layer is now saved as custom property instead of an unsupported XML-attribute.
• Implemented a Tag annotation that can be used to provide default tags for a custom IEntity implementation
• Registering a MapObjectLoader no longer requires a type
  • The MapObjectType is already provided by the IMapObjectLoader.getMapObjectType method and therefore all MapObjectLoader implementations already have this information which makes it redundant to specify in separately when registering a new MapObjectLoader.
• Implemented possibility to provide an AffineTransform for the CursorImage

Changes

• Added a new namespace de.gurkenlabs.litiengine.pathfinding that contains all path finding implementations
  • Added a new sub-namespace for the AStar implementation de.gurkenlabs.litiengine.pathfinding.astar
  • Previously this was all located under de.gurkenlabs.litiengine.physics
• Lowered the DEFAULT_MAX_DISTANCE for sounds to be heared from 250px to 150px.
• An entity SoundPlayback now evaluates its position by the center of the entity.
• Remove the ~~Sound.find~~ method and rename the ~~Sound.load~~ method to Sound.get for
  • For sounds, its not necessary to differentiate between the two because actually the load method just reused the find method as default and only loaded something if the sound wasn't already present.
• Moved the Direction enum to the more general namespace de.gurkenlabs.litiengine.
• Rename the Particle.getLocation method to Particle.getRenderLocation.
• Setting the location on a GuiComponent now also updates its children
• Pulled out all Font related attributes of the Appearance
  • Font information and Text alignment on a GuiComponent, for example, are strongly dependent on each other, making it necessary to have them in one place. Introduce a GuiProperty "defaultFont" to facilitate Font setup.

Major overhaul on the AmbientLight and Shadow Rendering

We now basically create an additional dynamically created tile layer and render the individual tiles. When a light/shadow is added/removed/moved or changed only the affected tiles are updated on the dynamic layer.

Previously an image of the size of the entire map had to be redrawn which resulted in a major performance issue and made actually dynamic lighting almost impossible.

The Game is now processing command line arguments when being initialized

The Game.init(String...args) now optionally takes in command line arguments from the applications main method. There are two default command line arguments at the moment that are being processed:

• -release : If set, this argument disables all debugging functionality. This is particularly useful for deployment
• -nogui: If set, this argument will not spawn a JFrame. This can be usesful for e.g. a gameserver or unit tests

Major refactoring on the whole event management

With the previous implementation, it wasn't possible to remove listeners from the event handling because we only provided a lambda implementation. With this change, large parts of the engine were refactored to provide proper add/remove methods.

Also, this changed reuses EventListener class as base class for all custom engine listeners. We've provided either adapter implementations or more fine granular listeners that only provide certain callbacks to allow the user of the API to decide what he actually wants to listen to.

There are still some events in the engine that need to be refactored in the future.

#118 Change MapObject position and size from int to float.

Add a custom XmlAdapter that makes sure that the float values are serialized like integers (without decimal digits) when they are technically integers. This was necessary to keep the format consistent with the tiled map format.

#125 Overhaul of the GameInfo

This change takes care of the inconsistencies of the GameInfo class. It not only provided information about the game but also the defaultRenderScale and even some unused fields.

We've also extended the GameInfo with more detailed information about the game (e.g. publisher or website) and additionally provided the possibility to add custom properties for even more project specific information.

#129 Overhaul on the EntityController management

Problem Previously, the whole management of controllers that are related to entities was really inconsistent. They were also managed globally, although an entity instance always had to be present in order to retrieve them. There were also some issues with the EntityControllerManager returning wildcard types whilst this essentially added no value. The basic interfaces for the controllers were all generic as well which required such an implementation.

Goal Make the basic controller interfaces non-generic while keeping the syntactic sugar to have a generic implementation for the actual classes. With this change, the controllers are managed similar to a component-based system and can be directly used/set/retrieved from an IEntity.

Also, this refactoring adds a method that allows to simply scale the sprite for an IEntity with a simple method on the IEntityAnimationController.

#130 Refactoring on the Environment rendering pipeline

Re-work the whole implementation of the Environment's rendering pipeline.

It is now more straight forward and less confusing to understand:

BACKGROUND-> GROUND-> SURFACE-> NORMAL -> (static shadows) -> OVERLAY-> (ambient light) -> UI

We still keep the named RenderType enum because it makes it easier to understand compared to e.g. an alternative approach with just numbers. Also it transfers the original design idea for the rendering pipeline.

IRenderable implementations can now be registered for any of the RenderType values.

Internally, the Environment.render method does the following for every RenderType (besides RenderType.NONE):

1. Render all Map Layers of that type
2. Render all registered IRenderable implementations of that type
3. Render all added IEntities of that type
4. Call-back on the EnvironmentRenderListener.rendered listeners for that type
5. If dbg_logDetailedRenderTimes = true: track the time it took to execute the rendering

Regarding issue #128: It's now possible to render something behind GROUND layers using RenderType.BACKGROUND or the related call-back:

Game.getEnvironment().addRenderListener(RenderType.BACKGROUND, (g, t) -> {
  // render something on the graphics object g
 });

  • It is now possible to set the offset for a static shadow
  • It is now possible to set the color for static shadows on the map
• Unified MapObjectProperty naming and clean up unused constants
• Reused JAXB class contexts because they're performance crucial
• Removed unused and meanwhile deprecated GameDirectories.
• Removed the concept of IVision from the engine because the implementation is very specific for certain types of games (like rts/moba).
  • Replaced the logic on the RenderEngine by the possibility to provide a render clip for the rendering process
• Cleaned up IRenderEngine interface
  • All methods that depend on the current camera (render the respective object relative to the viewport) are now provided directly on the IRenderEngine interface instead of being static methods on the RenderEngine class.This way, it is easier to determine which methods take the camera into account internally and which don't.

This release is the initial LITIengine release available to the public after the port to GitHub. Still a lot of implementation and documentation (!) to do.

The environment builder tool utiLITI is currently not included but the engine itself is functioning and can already be used to make some games.
