[2.0-rc.11] - 2026-04-21

Breaking Change

  • Removed C# scripting support. AngelScript is now the only supported scripting language.

Added

  • Project manager new functionalities:
    • Added a search bar to the top menu for finding projects.
    • Added "Scan" button to search for projects inside a folder recursively.
    • Added a favourite button for every project in order to show it at the top.
    • Added the current version of a project.
    • Added the last modification date for a project.
  • Support for exporting projects to Android and Web.
  • Each project now includes a project.cometProject file at its root to mark the folder as the project's entry point.
  • Opening the engine when the scripts project does not compile now can trigger two new popups:
    • Just once when the engine is opened, a popup saying that the scripts do not compile and that they should be fixed before anything else is triggered.
    • When the scripts now compile correctly (only once and just if the engine was opened when they did not compile correctly) a new popup saying that it is better to reload the project is triggered.
  • Support for playing videos:
    • VideoClip: New resource that can read video files.
    • VideoPlayer: New behaviour class that is used to display a video clip in some different modes.
  • The .fnt files can now be imported and used as BitmapFont to render using BehaviourText.
  • Slider to modify the volume when previsualizing an audio on the AudioSample inspector.
  • A text box explaining what is happening is now displayed in any collider inspector when an instanciable entity is selected, instead of showing nothing.
  • In a CometEvent, clicking an entity that owns a callback now highlights it in the hierarchy.
  • A behaviour can also be dropped inside a CometEvent and its Entity will be taken as reference.
  • Added the tag "Overriding" for the platform export options tab of the textures and texture atlas that are enabled.
  • The BehaviourText now uses the kerning of the font.
  • Now the inspector of a Font shows its texture and all the available glyphs.
  • Some AudioEffect parameters:
    • AudioEffectEcho: filter.
    • AudioEffectReverb: width, damp, roomSize, freeze, wetMix.
  • Script logs are now shown in the console panel with their script path, function name, and line number. Double-clicking a log entry opens and focuses the corresponding code in the editor.
  • AssetIcon now always shows the icon, even if the asset is not loaded.
  • Scenes referenced in the inspector of a Script or CometObject are now automatically included in the build.
  • New metadata attributes:
    • TreeNode: Makes a group with all the fields that has the same tree node name and shows them as a tree.
    • Tab: Makes a group with all consecutive fields that has a Tab attribute and shows them with tabs.
  • The BehaviourText now has a font by default.
  • Added a new (+) button in the Animation Event Inspector that allows adding a new event at the currently selected frame.
  • Added support for 9-sliced sprites using configurable borders to maintain correct aspect ratios. Borders have to be set using the SpriteEditor panel.
  • Added render modes for the SpriteRenderer and Image:
    • Simple: Renders the sprite normally (same as in previous versions).
    • Sliced: Uses the sprite’s borders for 9-sliced rendering, preventing distortion and preserving aspect ratio.
    • Tiled: Repeats the sprite using 9-sliced rendering, preserving the corners while tiling the edges and center.

  • Cameras that were rendering to a render texture were rendering to the game view as well.
  • Once an AudioMixerGroup was set to an AudioSource, it was not possible to remove it again.
  • Changing the 'Max Size' of a texture with no RGBA format in its inspector to a size that is smaller than the original was causing the texture to lose its alpha.

  • The pref directory was not working on Linux.
  • Default build platform was always Windows, now the default platform is the platform where Comet is running on.
  • Joysticks and haptics were not working on Linux.
  • Switching from fullscreen to windowed mode could cause parts of the screen that were outside the new resolution to retain old frame data instead of being properly cleared to black.
  • Filtering a resource by type in the project panel could cause multiple resource types to appear selected at once.
  • Filtering by instantiable entities in the project panel did not detect any, even when they were present.

  • Crash when the panel animation was playing an animation and then another entity clicked to select it.
  • Panel Project mode list various fixes.
  • Painting a tilemap could sometimes freeze the entire editor.
  • Shift-selecting assets did not preserve the correct order.
  • Controller Axis Y was inverted.
  • The version label in the Project Manager menu bar is now correctly positioned regardless of window width or version string length.
